Promote legal sportsbooks and earn $100-$400 per depositing user. With 38 US states now legal, the affiliate opportunity is massive. Top affiliates earn $20K-$100K/month driving signups.
Sports betting affiliate marketing is the business of sending people who want to bet to companies that take bets, and getting paid when those people deposit and lose money. That is the whole model. Everything else - the odds comparison widgets, the "best sportsbook in Ohio" listicles, the promo code pages - is packaging around that single transaction.
It is also one of the most heavily regulated forms of affiliate marketing that exists. In several US states you cannot legally take a commission without registering with a gaming regulator. In Great Britain you do not need your own licence, but the operator paying you is legally answerable for every word you publish, which means your content is governed by a rulebook you never signed. In Ontario, taking money from one legal operator can bar you from advertising anywhere else in the province. In Massachusetts, one of the two standard commission models is simply illegal.
Most guides to this niche skip all of that and lead with income claims. This one does the opposite, because the compliance detail is the business. If you get the regulatory side wrong you do not get a warning letter - you get your account terminated, your accrued balance forfeited under a clause you did not read, and in the worst case a state regulator asking your operator partner why it was paying an unregistered vendor.
What the deal actually is, mechanically
An affiliate agreement is a contract between you and a licensed gambling operator, or with a network acting for several operators. You publish content, you link out with a tracking parameter, the operator drops a cookie or records a click ID, and when a referred user opens an account and funds it, the operator attributes that player to you.
Three things are worth understanding before any discussion of rates.
You are being paid out of losses, not turnover. Almost every revenue share deal is calculated on net gaming revenue (NGR) or an equivalent "net revenue" figure, not on the amount wagered. If your referred players collectively win in a given month, your commission for that month can be zero or negative. This is not an edge case in sports betting, where a single upset weekend can swing an operator's margin sharply.
The operator defines the numbers. You do not audit the operator's books. You see the figures the operator's affiliate platform reports, and those figures are net of whatever the contract says they are net of. The bet365 Partner Programme terms are unusually explicit about this. Clause 5.1 defines Net Revenue as monies received in respect of bets placed, after deducting winnings paid to customers, betting duties, levies and taxes, bad debts, fraud and chargebacks, customer rewards and promotions, third-party royalties, jackpot contributions, payment organisation charges, and administrative costs. Every item on that list is a deduction taken before your percentage is applied.
The contract is terminable at will. Clause 7.5 of the same agreement confirms that either party may terminate with or without reason. That is the industry norm, not an outlier. You are building an asset whose revenue can be switched off by the counterparty with no cause given.
The licensing question, and why most guides get it wrong
There is no single answer to "do I need a licence". The answer is jurisdictional, and in the United States it is jurisdictional at the state level and further conditional on how you are paid.
Great Britain: no affiliate licence, but you are bound by the operator's rulebook
The Gambling Commission does not issue a licence category for marketing affiliates. Its public register covers gambling businesses, personal licences and premises. If you are not offering facilities for gambling yourself, you do not apply for anything.
That is not the same as being unregulated. Social responsibility code provision 1.1.2 of the Licence Conditions and Codes of Practice makes licensees "responsible for the actions of third parties with whom they contract for the provision of any aspect of the licensee's business related to the licensed activities". The contract must, among other things, require the third party to "conduct themselves in so far as they carry out activities on behalf of the licensee as if they were bound by the same licence conditions and subject to the same codes of practice as the licensee". It must also let the licensee "terminate the third party's contract promptly if, in the licensee's reasonable opinion, the third party is in breach of contract... or has otherwise acted in a manner which is inconsistent with the licensing objectives, including for affiliates where they have breached a relevant advertising code of practice".
Read that last clause carefully. It is a contractual kill switch, mandated by the regulator, triggered by an advertising code breach in the operator's reasonable opinion. You do not get a hearing.
The Commission's own guidance on affiliates and third parties reinforces the point on data: when affiliates conduct direct marketing, "we, and the ICO, consider that you are primarily responsible for any breaches" - "you" being the operator. Its guidance on licensees' responsibilities for third parties states that the responsibility for compliance "sits with the licence holder and cannot be transferred to any other party", and that failure to maintain adequate control of third parties "can result in regulatory action including suspension or the loss of the operating licence".
The practical consequence is that British operators run affiliate compliance defensively. They audit creative, they demand pre-approval, and they cut affiliates quickly, because the alternative is explaining an affiliate's landing page to a regulator that can suspend their licence. A single UKGC notice from May 2019 illustrates the reach: operators were told they must ensure age verification before customers can access free-to-play games through affiliate websites, because the operator cannot benefit from affiliate advertising that offers unprotected free-to-play versions. Self-declaration of date of birth was explicitly ruled insufficient.
United States: registration is real, and the payment model is the trigger
Several US states require affiliates to register with or be licensed by the gaming regulator before they can be paid. Crucially, in a number of them the requirement is triggered by how you are compensated. Flat media buys often fall outside the regime; cost-per-acquisition and revenue share often fall inside it.
Pennsylvania is the state where the figures can be verified directly from the regulator. The Pennsylvania Gaming Control Board's published Schedule of Fees sets out, for Gaming Service Providers - the category affiliates fall into:
- Gaming Service Provider Registration: 2,500 US dollars for an initial five-year term, 2,500 dollars to renew, plus a 500 dollar non-refundable applicant investigation deposit, 60 dollars per affiliated entity and 60 dollars per principal or key employee.
- Gaming Service Provider Certification: 5,000 dollars initial and 5,000 dollars renewal, with a 2,500 dollar applicant deposit, 500 dollars per affiliated entity and 1,000 dollars per principal, principal entity or key employee.
- Gaming-Related Gaming Service Provider Certification: 10,000 dollars initial and renewal, with the same 2,500 dollar deposit structure.
- Interactive Gaming Service Provider Registration sits at 2,500 dollars with a 500 dollar deposit; Interactive Gaming Service Provider Certification at 5,000 dollars with a 2,500 dollar deposit.
For scale, the same schedule prices a Sports Wagering Certificate at 10 million dollars and a Sports Wagering Operator licence at 50,000 dollars. You are not being asked to pay operator money. You are being asked to submit to an operator-style background investigation for the privilege of a few thousand dollars of paperwork.
Tennessee is the clearest illustration of the payment-model trigger, and it is written into statute. The Tennessee Code's definition of "Vendor" states that the term "does not include marketing affiliates who are compensated by a method other than a revenue sharing agreement". In other words: take a CPA and you are outside the vendor regime; take a percentage of revenue and you are a vendor. That matters, because Tennessee's vendor registration fees under the Sports Wagering Council's rules are not affiliate-scale. The rules set a first-period registration fee of 150,000 dollars payable in three annual instalments of 50,000 dollars, with subsequent-period fees ranging from 150,000 dollars for geolocation, platform software or player account management vendors down to 30,000 dollars for KYC, payment processing "or similar material services". The published schedule does not contain a category obviously drawn for marketing affiliates. This audit could not confirm from a primary source what fee a revenue-share affiliate in Tennessee would actually be assessed; the honest answer is that you would need to ask the Council directly before signing a revenue share deal for that state, and that the downside risk is a five-figure registration bill against a marketing arrangement.
Beyond those two, an industry tracker maintained by BettingUSA, last updated in May 2026, lists the following. Treat these as a starting point for enquiry, not as gospel - the Pennsylvania figures in that list match the regulator's own schedule, which is reassuring, but fee schedules change and the tracker is secondary.
- Arizona: licence required, roughly 1,500 dollars initial and 500 dollars renewal.
- Colorado: a Vendor Minor licence for CPA arrangements at around 350 dollars; a Vendor Major licence for revenue share at around 1,200 dollars plus a 10,000 dollar background investigation deposit, with investigator time billed hourly. Colorado's own published definitions confirm the split: a Vendor Major licence is required where a party "provides products, services, information or assets" to a licensed operator and "receives, therefore, a percentage of gaming revenue"; a Vendor Minor licence covers everyone else acting on an operator's behalf.
- Indiana: around 500 dollars for CPA arrangements, with a separate tier for revenue share.
- Michigan: around 200 dollars for vendor registration on flat-fee or CPA terms; supplier-level fees for revenue share.
- New Jersey: vendor registration for CPA or flat fee, submitted by the operator; an Ancillary Casino Service Industry Enterprise licence with a 2,000 dollar application fee for revenue share.
- Virginia: around 500 dollars application and 500 dollars renewal on a three-year term.
- West Virginia: around 1,000 dollars registration.
- Louisiana: a threshold model, with a vendor permit required above roughly 500,000 dollars of annual earnings and a waiver application below it.
- No affiliate licensing currently required in several states including Iowa, Mississippi, Wyoming and Washington DC.
Sources disagree on some of these numbers. A separate industry summary attributed to the same publisher's chief executive lists Colorado, Tennessee, Virginia and Indiana all at 500 dollars, New Jersey at zero, Pennsylvania at 2,500 dollars, West Virginia at 1,000 dollars and Michigan at 200 dollars. The Colorado figure in particular is quoted at both 350 and 500 dollars in different places, and this audit could not confirm either from the Colorado Division of Gaming's own published fee schedule. Verify with the regulator before budgeting.
Two states prohibit one of the two commission models outright, and this is the detail that catches people. Massachusetts regulation 205 CMR 256.01(3) bars an operator from entering an agreement with a third party to conduct advertising or marketing on its behalf "in exchange for a percentage of sports wagering revenue earned from users that the third party directs or causes to be directed to the Operator". Revenue share is not permitted in Massachusetts. That rule is itself the survivor of a wider ban: the version of 205 CMR 256 originally adopted prohibited any third-party marketing compensation "dependent on, or related to, the volume of patrons or wagers placed, or the outcome of wagers", which would have swept up CPA as well. Affiliates and operators argued at a Gaming Commission roundtable in February 2023 that affiliate marketing is pull rather than push advertising and that a blanket ban would push consumers toward illegal operators; the Commission amended the rule to permit CPA while keeping the revenue share prohibition. Trade reporting on that same Massachusetts rulemaking states that Illinois runs the identical asymmetry - revenue share prohibited, CPA permitted - and that Connecticut runs it in the opposite direction, prohibiting CPA while allowing revenue share. This audit could not verify either from the primary Illinois or Connecticut regulations, and you should confirm with the regulator before structuring a deal for those states.
If you build a single national US site on revenue share deals, you have to geo-exclude Massachusetts and Illinois. If you build it on CPA, you have to geo-exclude Connecticut. There is no configuration that is simultaneously legal everywhere on one deal type.
Ontario: the exclusivity trap
Ontario does not, on the AGCO's published guidance, require marketing affiliates to register in their own right. Standard 1.19 of the Registrar's Standards for Internet Gaming places the obligation on operators: they "are responsible to ensure that any third parties that they contract, including entities commonly referred to as 'marketing affiliates' advertising on the operator's behalf, also meet the standards".
Standard 1.21 is the one that reshapes your business. Any marketing affiliate that advertises for the Ontario market "must not also advertise gaming sites that operate in Ontario without AGCO registration". For an established international affiliate site carrying grey-market brands, that is a hard choice: firewall Ontario completely, or purge every unregistered brand from your entire portfolio.
Standard 2.05 then removes the single highest-converting content type in the niche. Public advertising of inducements, bonuses and credits is strictly prohibited, including targeted advertising and algorithm-based ads, and the AGCO has confirmed this covers "links and descriptions provided by affiliates". The bonus code page - the format that most sports betting affiliate sites are built around - cannot exist for Ontario traffic.
Brazil and Australia
Brazil regulated fixed-odds betting from 1 January 2025. Affiliates are expressly defined in the rules of the Secretaria de Prêmios e Apostas, operators must hold written Portuguese-language contracts with them, and operators remain jointly and severally liable for advertising conducted by affiliates, influencers or third-party platforms under their brand. Advertising must carry mandatory 18-plus and harm warnings occupying a minimum of 10 percent of the advertising space. Welcome bonuses and upfront incentives were banned at market launch. The effect on affiliate volumes was severe and is visible in listed-company reporting: Better Collective attributed a substantial part of a 25 percent year-on-year decline in new depositing customers in the fourth quarter of 2025 to the Brazilian regulatory transition, specifically the prohibition of welcome bonuses redirecting new player activity to offshore sportsbooks.
Australia already restricts gambling advertising around live sport. Between 5:00am and 8:30pm, no gambling advertising or promotion of odds is permitted from five minutes before the published scheduled start of play until five minutes after play, including during breaks, on broadcast television and radio and on live sport streamed over the internet. A far broader reform package has been proposed, with the bulk of measures commencing 1 January 2027 pending parliamentary approval: a ban on notable persons including athletes, celebrities and influencers endorsing wagering products; frequency caps; bans around school pick-up times; and a "triple lock" for online content services requiring a registered account, age confirmation and opt-in consent before wagering advertising can be served. Affiliates are explicitly inside the perimeter: the drafting defines wagering advertising as content "by, on behalf of, or for the benefit of" licensed providers, which captures anyone in a commercial arrangement with an operator. Separately, the Interactive Gambling Act 2001 prohibits advertising banned services in Australia at all, which makes promoting offshore casino brands to Australian traffic a legal exposure rather than a grey area.
CPA versus revenue share: the arithmetic nobody publishes
No major sportsbook publishes its affiliate CPA rates. The figures that circulate - 100 to 400 dollars per depositing customer, and higher - are industry chatter, repeated between affiliate blogs without a traceable source. Treat any specific number you see, including on this page, as an estimate unless it comes from an audited filing.
There is one class of source that is auditable: the annual reports of listed affiliate companies. Better Collective A/S, which operates a large portfolio of sports betting media assets, reports both revenue by commission model and the number of new depositing customers (NDCs) it delivers. Its 2025 annual report gives the following.
- Group revenue of 337 million euros, down from 371 million euros in 2024.
- Revenue share income of 157.5 million euros (down 13 percent year on year) and CPA income of 80.0 million euros (down 13 percent), with revenue share accounting for 47 percent of group revenue, CPA 24 percent, subscription 5 percent and other income 24 percent.
- 1,200 thousand NDCs for the full year 2025, against 1,754 thousand in 2024 and 1,916 thousand in 2023.
- In the fourth quarter of 2025, 305 thousand NDCs, of which 73 percent were generated under revenue share agreements.
From those figures you can derive an order of magnitude, with caveats. Dividing fourth-quarter CPA revenue of 22.5 million euros by the roughly 82 thousand NDCs delivered on CPA terms in that quarter gives an implied average of about 270 euros per CPA-referred depositor. That number is a global blend across many markets and includes upfront components of hybrid contracts, so it is not a rate card. But it is the closest thing to an audited figure available, and it suggests that the commonly quoted 100 to 400 dollar range is broadly the right neighbourhood for a company with real negotiating leverage. An individual with a new site should assume the bottom of that range or below, and should assume the top of it is reserved for partners delivering thousands of customers a month.
The same report gives a usable, if rough, view of blended value across both models: revenue share plus CPA income of 237.5 million euros against 1,200 thousand NDCs is about 198 euros per NDC. That figure understates per-cohort economics in one direction and overstates it in another - revenue share income in any given year comes partly from players referred in earlier years, while the NDC count is current-year only - so it should be read as a scale indicator, not a unit economic.
When revenue share beats CPA
The break-even is simple arithmetic. If a CPA offer is worth C and a revenue share offer pays r percent of NGR, revenue share wins once cumulative NGR from that player exceeds C divided by r.
At C of 270 euros and r of 30 percent, the referred player must generate about 900 euros of lifetime net revenue for the operator before revenue share pulls ahead. At r of 40 percent, about 675 euros. At a more realistic new-affiliate CPA of 100 euros and r of 25 percent, the crossover is around 400 euros of lifetime NGR.
Whether your players clear those thresholds depends almost entirely on who they are. A promo-code hunter arriving from a "best sign-up bonus" page has been selected for price sensitivity: they take the offer, they may never deposit again, and they are the ideal CPA player and a poor revenue share player. A reader who arrives from an in-depth analysis piece and stays for the odds comparison tool is a plausible revenue share player. Affiliates who understand this route different traffic sources to different deal types, which is exactly what hybrid deals - an upfront CPA plus a lower ongoing percentage - are designed to accommodate.
Better Collective's disclosed mix is instructive here. It has been deliberately shifting its North American business from CPA toward revenue share, and stated that it expected to generate approximately 10 to 15 million euros in clean revenue share from the North American market, against which it reported 17 million euros of pure revenue share for the year. The trade-off it describes candidly: the shift "temporarily impacted" reported revenue because upfront payments are deferred into recurring income. If a company with that balance sheet finds the transition painful, a solo operator financing content production out of cash flow should think hard before giving up upfront money.
Negative carryover, and the other clauses that quietly eat commissions
Negative carryover is the single most consequential term in a revenue share contract and the one least likely to be discussed in a "how to start" guide.
Under a revenue share deal your monthly commission is a percentage of NGR from your referred players. When those players win more than they lose in a month, NGR is negative. The question is what happens next. Under a no-carryover programme, your balance resets to zero and you start the following month clean. Under negative carryover, the deficit rolls forward and must be recovered from future NGR before you are paid anything again.
Programmes vary and the variation is contractual, not conventional. Two published examples show the range.
- The bet365 Partner Programme terms state at clause 5.2 that negative commission balances in any vertical will be deducted from available commissions. That is cross-product netting: a bad month on one product reduces what you are paid on another.
- 22Bet Partners operates a narrower version. Its high-roller policy defines a customer who generates at least 10,000 dollars of negative net revenue in a month as a "high-roller", and permits negative revenue from that customer to be carried forward against future earnings from the same customer - but the negative cannot be applied against other customers' revenue, and cannot exceed the total aggregate negative revenue for the brand in that month.
The difference between those two structures is the difference between one lucky punter costing you a customer's future earnings and one lucky punter costing you a quarter.
Negative carryover is not the only clause worth reading before signing.
Minimum activity thresholds. The bet365 terms require a minimum of 15 active customers before you are eligible for any referral commission payment at all. A site that refers ten players a month earns nothing, indefinitely.
Dormancy and forfeiture. The same agreement operates a dormancy process at clause 11: accounts that go three months without 15 referrals trigger notices, then a 50 percent reduction of the accrued balance, then potential closure after six months of inactivity. Half your accrued earnings can be written off because you stopped publishing for a quarter.
Declining rates on inactivity. 22Bet's terms reduce commission to 15 percent if no new first-time deposits occur within six months, and to 5 percent after twelve months. A revenue share tail is not passive income if the rate decays when you stop working.
Payment thresholds. 22Bet sets a 100 dollar minimum withdrawal. Below that, your money sits with the operator.
Deductions before your percentage. Return to the bet365 Net Revenue definition. Betting duties and taxes are deducted before your share is calculated. This is not academic. The UK government has confirmed that Remote Gaming Duty rises from 21 percent to 40 percent from 1 April 2026, and that a new tiered General Betting Duty takes effect from 1 April 2027 with a 25 percent rate on remote betting other than remote bets on UK horseracing, which stays at 15 percent. Separately, a statutory levy on gambling operators commenced on 6 April 2025 under the Gambling Levy Regulations 2025, charged at 1.1 percent of the leviable amount for online operators, with rates falling to 0.1 percent for some land-based and lottery categories and a small number of licence types excluded. If duties and levies are deducted before your commission is computed, a large duty increase reduces your commission on identical player behaviour. Whether it does in your specific contract depends on the wording, and you should check it.
A worked model
The following is arithmetic, not a case study. There is no real person behind it and no claim that these results are typical or achievable.
Assume a British-focused site that publishes for twelve months and reaches a position where it refers 25 new depositing customers a month on a 30 percent revenue share with negative carryover, plus a small number of CPA placements.
Inputs, and where they come from:
- 25 NDCs per month. Assumption, not sourced.
- Average net revenue per referred player of 40 pounds per month in the first three months, declining thereafter as casual bettors churn. Assumption, not sourced. There is no public dataset of per-player NGR for affiliate-referred sports bettors, and any figure you see quoted is an estimate.
- 30 percent revenue share. Within the commonly quoted range; not confirmed from any operator's published rate card.
Month twelve, on those assumptions, might see roughly 120 to 180 players still generating measurable activity out of 300 referred, producing perhaps 3,000 to 5,000 pounds of monthly NGR and therefore 900 to 1,500 pounds of monthly commission - before any negative month.
Now introduce one negative month. A high-margin weekend for punters wipes out the month's NGR and produces minus 2,000 pounds. Under negative carryover, you earn nothing in that month and nothing the following month until the deficit clears. Two months of income, gone, from an outcome you had no influence over. Under a no-carryover programme, you lose one month.
Now introduce the bet365-style dormancy clause. You take a two-month break. Referrals fall below the threshold. Notices are issued. Fifty percent of the accrued balance is removed.
None of this is exotic. All three mechanisms are in published contracts quoted above. The point of the model is not the revenue figure - which is invented and labelled as such - but the shape: revenue that looks like an annuity, governed by terms that behave like an option held by the counterparty.
The advertising rules actually constrain what you can write
This is where sports betting affiliate content diverges hardest from ordinary affiliate marketing. In most niches, advertising standards are a background consideration. Here they determine the page.
Great Britain
The CAP Code section on gambling explicitly applies to "marketing by third parties (for example, affiliate marketers) acting on an advertiser's behalf". You are inside the code whether or not you knew it existed.
The binding constraints include:
- Rule 16.3.12: advertisements must not be likely to be of strong appeal to children or young persons, "especially by reflecting or being associated with youth culture". In a sport-adjacent niche this is a live risk, not a theoretical one - the whole point of your content is proximity to football, and footballers are of strong appeal to children.
- Rule 16.3.14: no one who is, or appears to be, under 25 may be shown gambling or feature in a significant role. Those aged 18 to 24 may appear only on transactional platforms to illustrate specific betting selections.
- Rule 16.3.13: advertisements must not be targeted at under-18s through media choice or placement context.
- Rule 16.3.4: advertisements must not suggest gambling can be a solution to financial concerns, an alternative to employment, or a way to achieve financial security.
That last rule kills an entire content format. "Make money from betting", "beat the bookies", "supplement your income with matched betting" - all of it sits on the wrong side of 16.3.4 when published as advertising for a gambling operator.
Enforcement is also being automated. From 11 June 2026 the Committee of Advertising Practice deployed an AI-based Active Ad Monitoring System, working with social media platforms, as part of a content marketing sweep to identify gambling advertising of strong appeal to under-18s, with takedown demands, platform referrals and Gambling Commission fines available as sanctions. Content that survived by not being noticed will be noticed.
Massachusetts, in detail, because the text is instructive
205 CMR 256 is worth reading in full even if you never target Massachusetts, because it is a clear articulation of what regulators across the US are converging on.
- Operators are responsible for the content and conduct of all advertising done on their behalf or to their benefit, whether by employees, agents, affiliated entities or third parties under contract, "regardless of whether such party is also required to be licensed or registered".
- Every advertisement must disclose the identity of the sports wagering operator.
- Advertising may only be disseminated in the state by or on behalf of operators licensed there, unless the advertisement clearly states the offerings are not available in the Commonwealth. Advertising forms of illegal gambling in the state is prohibited outright.
- Promotions must be explained clearly, and where a promotion requires the patron to wager their own money, the required amount must be disclosed in the same size and style of font as the bonus amount, and "the complimentary item or promotional credit shall not be described as free".
- Advertising must not imply sports wagering is free of risk, describe it as "free", "cost free" or "free of risk" where the player must risk their own money, encourage chasing losses or reinvesting winnings, suggest betting solves financial or personal problems, imply that chances of winning increase with time or money spent, or be placed on any page devoted primarily to responsible gaming.
- Advertising must state that patrons must be 21 or older, must not appeal primarily to under-21s, and must not be placed in media used primarily by under-21s, at events where 25 percent or more of the audience is expected to be under 21, at schools, on any college or university campus, or in college newspapers or broadcasts. Depicting students, schools or college settings is prohibited.
- Responsible gaming messaging carrying the state problem gambling helpline is mandatory, with prescribed minimum font sizes: for print and signage, the greater of the majority body text size or 2 percent of the height or width; for billboards, at least 5 percent; for websites including social media, at least the same size as the majority of the page text, posted conspicuously on each page.
That last item is the one affiliates routinely miss. A responsible gambling line in 10-pixel grey at the foot of the page does not satisfy a rule requiring it to match the body text.
The US enforcement record
Ohio provides the clearest evidence that these rules are enforced against advertising language rather than against gambling itself. In the first week of January 2023, days after legal betting launched, the Ohio Casino Control Commission issued notices of violation carrying potential 150,000 dollar fines to the parent companies of BetMGM, Caesars and DraftKings over advertising and promotions - specifically the use of "free" and "risk-free" and failures to display required problem gambling messaging. Settlements followed. Caesars and BetMGM each paid 150,000 dollars; DraftKings paid 500,000 dollars to resolve two matters, including mailing advertisements to people too young to bet. Ohio collected more than a million dollars in fines in the first year of legal sports betting.
Those penalties fell on operators, not affiliates. But the operator that has just paid 500,000 dollars for using the word "free" is not going to tolerate an affiliate whose homepage headline is "Claim your risk-free bet". The compliance pressure travels down the chain as contract terms and content approvals.
Ontario and Brazil
Ontario's Standard 2.05 prohibition on publicly advertising inducements, bonuses and credits applies to affiliate links and descriptions. Brazil requires 18-plus and harm warnings occupying at least 10 percent of the advertising space, prohibits presenting betting as a source of income, and holds operators jointly and severally liable for affiliate advertising.
The through-line across all four jurisdictions: the bonus offer is the highest-converting hook in the niche, and it is the thing regulators are most actively restricting.
How the regulation tightened, and what it did to volumes
It is worth laying the sequence out, because the direction of travel is one way.
In Great Britain: the 2005 Act's advertising settlement began being unwound in stages. CAP tightened the strong appeal test in 2022. The 2023 gambling review produced a statutory levy, which commenced 6 April 2025 at 1.1 percent of gross gambling yield for online operators, replacing voluntary contributions. Online slot stake limits followed: 5 pounds per spin for adults went live on 9 April 2025, and 2 pounds per spin for 18 to 24 year olds on 21 May 2025. Financial risk assessments were confirmed on 7 July 2026 on a staged basis, beginning with net deposits of 5,000 pounds in a rolling 24 hours for those aged 25 and over and 2,500 pounds for under-25s, moving eventually to 1,000 pounds in 24 hours or 3,000 pounds in 90 days for those 25 and over, and 750 pounds or 2,000 pounds for under-25s. Then the tax: Remote Gaming Duty to 40 percent from 1 April 2026, and remote General Betting Duty to 25 percent from 1 April 2027.
Every one of those measures reduces the amount of money an operator makes from a given customer, and revenue share commission is a slice of that number.
In the US, the pattern is state-level advertising codes with real fines, plus the spread of vendor registration. In Ontario, an advertising regime that removed the bonus hook and imposed portfolio exclusivity on affiliates. In Brazil, a regulated launch that banned welcome bonuses outright and pushed acquisition volume offshore.
The volume effect is measurable in listed-company reporting. Better Collective delivered 1,916 thousand NDCs in 2023, 1,754 thousand in 2024 and 1,200 thousand in 2025 - a 37 percent decline across two years. Its Publishing segment, the part of the business built on organic search, saw CPA revenue fall from 40.5 million euros in 2024 to 20.0 million euros in 2025, a decline of about 51 percent in a single year. Average full-time headcount fell from 1,773 in 2024 to 1,504 in 2025, a decline of about 15 per cent. Note the trap in the company's own five-year summary table: its columns run Q4 2025, Q4 2024, then the full years, so the first two figures on that row are quarterly averages, not annual ones. The full-year numbers above are taken from Note 5 of the financial statements.
Regulation is not the only cause. The company's own risk disclosure names the other one plainly: its Publishing business relies in part on organic search traffic, and changes to search engine algorithms, ranking methodologies or referral mechanisms - including "the increasing use of AI-driven search features and large language" models - may adversely affect the visibility and discoverability of its content. It has responded by investing in brand-led traffic, diversified formats and alternative acquisition channels specifically to reduce reliance on search.
That is one of the largest listed sports betting affiliate businesses telling its shareholders that the search-traffic model it was built on is structurally exposed. Anyone planning to build a comparison site on organic search rankings in 2026 should read that sentence twice.
The paid channel is tightening in parallel. Google requires certification to run gambling ads, restricts certification to specific websites, and will not certify sites on free hosting platforms, subdomains using third-party root domains, domains with no gambling association, or second-level domains the advertiser does not own and operate. Aggregator and comparison destinations may promote gambling content but "must not offer gambling services themselves or link to gambling services they own", and may not promote gambling that fails to meet country-specific licensing requirements. From 23 March 2026, all accounts seeking to advertise in gambling and games categories must demonstrate good policy health, and manager accounts with substantial volumes of revoked gambling certificates lose the ability to apply for new certificates and have existing certifications revoked. Better Collective characterised the January 2026 tightening as a positive structural development that would limit unlicensed operators in the auction - which is true, and also means the entry cost of the paid channel went up.
What it actually costs to start
Honest ranges, with the sourced items marked.
Sourced. US state registration where required: Pennsylvania Gaming Service Provider Registration at 2,500 dollars for five years plus a 500 dollar investigation deposit, per the PGCB fee schedule. Other states, per the industry tracker cited above, in the low hundreds to low thousands, with Colorado's Vendor Major route carrying a 10,000 dollar background deposit plus hourly investigator billing.
Estimated. Everything else. A domain, hosting and a content management setup can be done for under 200 pounds or dollars a year. Content is the real cost, and it is a labour cost: this niche demands sport-specific knowledge, regulatory accuracy per jurisdiction, and constant maintenance as promotions and rules change. If you outsource writing, budget for specialist rates rather than general freelance rates, because a writer who does not know that "risk-free" is prohibited in Ohio and Massachusetts will produce content that gets your operator partner fined. This audit could not source a defensible per-word market rate for regulated gambling content and will not invent one.
Frequently underestimated. Legal review of affiliate contracts. Geo-targeting infrastructure so that Ontario, Massachusetts, Illinois and Connecticut traffic sees compliant offers. Ongoing monitoring of rule changes across every jurisdiction you serve. Accounting for commission income that may be denominated in a foreign currency and paid net of deductions you cannot audit.
Tax and structure vary by country - check locally
Affiliate commission is trading income in the jurisdictions covered here, and it is taxable. Beyond that, do not take generic advice.
In the UK, affiliate commission is self-employment or company income depending on how you are structured, and there is no gambling-winnings exemption available to you, because you are not gambling - a distinction people get wrong surprisingly often. In the US, treatment depends on entity choice and state nexus, and receiving a state gaming registration may itself create filing obligations. In Canada, business income rules apply and Ontario's regime adds provincial considerations. In Australia, commission from promoting wagering is ordinary income, and the Interactive Gambling Act creates a separate legal exposure if you promote prohibited services.
Where you are tax resident, where your company is incorporated, and where your audience is located can all be different, and each can matter. This page is not tax advice. Speak to an accountant who has handled gambling affiliate income specifically, before you take the first payment rather than after.
What actually goes wrong
Your programme terminates you and you lose the balance. Termination at will is standard. Combine it with a dormancy clause that reduces accrued balances and you have a real risk of working for months and being paid nothing.
A negative month becomes a negative quarter. Under carryover, a single winning run by your referred players can suppress income for months. You have no control over this and no visibility into it until the statement arrives.
You promote a brand that loses its licence, or never had one. Promoting an unlicensed operator to a regulated market is the fastest way to become a legal problem rather than a commercial one. Ontario Standard 1.21 makes it a portfolio-wide issue; Massachusetts 205 CMR 256.02(2) prohibits advertising forms of illegal gambling in the state; Australia's Interactive Gambling Act prohibits advertising banned services outright.
Your traffic disappears in an algorithm update. This is not a hypothetical risk. It is disclosed as a principal risk by one of the largest listed affiliate businesses in the sector, whose Publishing segment CPA revenue halved in a year.
You breach an advertising code without realising. The word "free" attached to a bonus that requires a deposit is prohibited in Massachusetts and has produced six-figure fines in Ohio. "Beat the bookies" framing falls foul of CAP 16.3.4 in Great Britain. A stock image of a person who looks 22 celebrating a win falls foul of CAP 16.3.14.
You register in a state and discover the investigation is the real cost. Background investigations require ownership disclosure, criminal history, fingerprinting in several states, and in Colorado the investigator's time is billed hourly against a deposit. The application fee is the smallest part of the bill.
You build on bonus content and the jurisdiction bans bonus content. Ontario did it. Brazil did it. The format most affiliate sites are structured around is the format under most pressure.
Who should skip this
Be blunt about the exclusions.
Anyone uncomfortable with the underlying economics. You are paid, under revenue share, in proportion to how much money the people you referred lose. There is no reframing that changes this. If that sits badly with you, it will sit worse in year three when you can see the cohort data.
Anyone who wants passive income. Every published contract examined here penalises inactivity. bet365's dormancy process can remove half an accrued balance. 22Bet's rate falls to 15 percent after six months without new depositors and 5 percent after twelve. The revenue tail is conditional on continuing to work.
Anyone who cannot budget for compliance. If the idea of paying 2,500 dollars to Pennsylvania, plus a background investigation, plus legal review of each contract, plus geo-targeting infrastructure, sounds like unnecessary overhead, this niche will remove you from it eventually.
Anyone building a single global site. The commission model that is legal in Massachusetts is illegal in Connecticut. The bonus content that converts everywhere is banned in Ontario and Brazil. The portfolio of brands that pays well internationally can disqualify you from Ontario entirely. One site, one deal type, one content template does not work here.
Anyone whose plan depends on organic search rankings holding. One of the sector's largest listed players is actively reducing its dependence on that channel and has told shareholders why.
Anyone in a jurisdiction where the promotion itself is unlawful. Several countries prohibit advertising gambling services, and promoting an offshore operator into a regulated market can expose you personally. Check before you publish, not after.
Anyone under financial pressure looking for a quick result. The compliance work is front-loaded, the content asset takes months to rank if it ranks at all, and the first revenue share payment may be gated behind a minimum active customer threshold you have not met.
If you are still going ahead
A defensible sequence, in order.
- Pick one jurisdiction and read its rules end to end before writing anything. For Great Britain that means CAP section 16 and LCCP social responsibility code 1.1.2. For a US state it means the state's advertising regulation and its vendor or service provider registration requirements.
- Decide your commission model before you decide your content strategy, because the model determines which states you can serve and what registration you need. Revenue share excludes Massachusetts and Illinois. CPA excludes Connecticut. Revenue share triggers vendor status in Tennessee by statute.
- Read the affiliate agreement for negative carryover, cross-vertical netting, dormancy and forfeiture, minimum active customer thresholds, payment thresholds, and the definition of net revenue including what is deducted before your percentage. If the terms are not published, ask for them in writing before applying.
- Build the geo-targeting before the traffic, not after. Serving an Ontario visitor a bonus code page is a Standard 2.05 problem for your operator partner and a termination trigger for you.
- Assume the search channel degrades. Build an email list, a direct audience, or a distribution channel you own, on the explicit assumption that organic rankings are not durable.
- Keep records. Massachusetts requires operators to retain advertising records; Brazil requires written contracts in Portuguese; the UKGC expects operators to demonstrate oversight of third parties. Being the affiliate with clean, retrievable records of what was published when is a genuine commercial advantage when an operator is deciding which partners to keep.
- Re-read the rules every quarter. Between April 2025 and July 2026 alone, Great Britain introduced a statutory levy, two tranches of stake limits, a confirmed financial risk assessment regime and two announced duty increases; Google changed its gambling certification requirements twice; and Brazil's bonus ban reshaped one of the largest growth markets in the sector. Nothing in this niche stays still for a year.
