Inside the Casino Affiliate Industry: How the Revenue Model Works
07 Aug 2026
The casino affiliate industry — the marketing layer sitting between players and online gambling operators — has become a public, quarterly-reporting business, and it is having a difficult year. Gambling.com Group reported first-quarter 2026 revenue of $40.4 million, flat on the prior year, with its core marketing business down 5% and a proposed restructure that would cut roughly a quarter of its workforce. Better Collective, the largest listed company in the category, posted €86.3 million for the same quarter, up 5%, and told investors that 77% of the new depositing customers it delivered were on revenue-share contracts rather than one-off fees.
That distinction — a one-off fee versus an ongoing share — is the entire business. Affiliates are publishers: they rank comparison and review content in search, then sell the resulting audience to licensed operators. When a reader looks up Ontario online casinos, most of the pages that greet them are commercial properties earning a commission on whoever signs up. How that commission is calculated explains almost everything else about how these companies behave — what they publish, which markets they enter, and why several of them are now cutting costs.
Three ways an affiliate gets paid
A casino affiliate contract normally takes one of three forms, and each distributes risk differently.
CPA, or cost per acquisition, pays a fixed amount for every qualifying new depositor. Payment is usually gated on a minimum deposit and a minimum amount of real-money play, so the operator is not paying for accounts that register and then go quiet. It is fast, predictable and capped.
Revenue share pays a percentage of the net gaming revenue that referred players generate, for as long as those accounts stay active. Net gaming revenue is not turnover. It is what the operator keeps after player winnings, bonus costs, payment processing, platform fees and gaming tax have come out. The publisher's percentage is applied to a figure the operator calculates, which is why the contractual definition of that figure matters more than the headline rate.
Hybrid deals pair a reduced fixed fee with a reduced percentage. They have become the default for established content sites, because they give the publisher working capital while leaving the operator only partly exposed to players who do not last.
Two clauses do most of the negotiating work. Negative carryover determines what happens when referred players win more than they lose in a given month: under a carryover policy, the deficit rolls forward and the publisher earns nothing until it clears. The deduction schedule determines what the operator may subtract before the percentage is applied. A generous headline rate with an aggressive deduction schedule can be worth less than a modest rate without one.
| Deal structure | How the publisher is paid | Main trade-off |
|---|---|---|
| CPA | A fixed fee for each qualifying first-time depositor | Paid quickly, but no further income if the player proves valuable |
| Revenue share | A percentage of net gaming revenue for the life of the account | Slow to mature and exposed to deductions and negative carryover |
| Hybrid | A reduced fixed fee plus a reduced percentage on the same account | Splits the risk, and is usually offered only to proven publishers |
Media-led affiliates layer other revenue on top: display advertising sold on a CPM basis, sponsorships, subscriptions and data products. Better Collective's paid media line reached €27.6 million in the first quarter, split roughly evenly between revenue-share and CPA arrangements.
The industry is trading cash today for income tomorrow
The clearest trend in the published numbers is a deliberate move away from fixed fees.
Better Collective delivered 308,000 new depositing customers in the first quarter of 2026, broadly flat year on year — but the proportion on revenue-share contracts rose to 77%, from 73% three months earlier. Revenue-share income in North America grew 46% to €6 million, and recurring revenue across the group reached €50.1 million.
The logic is straightforward. A fixed fee is banked once. A percentage compounds for as long as the account survives, and it turns a lumpy media business into something closer to a subscription one. Investors pay more for the second kind.
The cost is patience, and cash. Revenue share takes months to mature, arrives unevenly, and depends on outcomes the publisher does not control — including how the operator's sports results run in a given quarter. Better Collective now reports Value of Deposits, a measure of what referred players actually pay into revenue-share accounts, precisely because the older headline metric of customer volume no longer describes the business.
Gambling.com Group has taken a different route and changed its product mix instead. Its sports data services grew 13% year on year in the first quarter while marketing revenue fell 5%, and full-year guidance was trimmed to around $165 million. Cost of sales rose 171%, largely because the company now pays for traffic that search once supplied at no cost.
Ontario shows what regulation does to the economics
Ontario is the most instructive case study available, because the market is open, competitive and fully documented.
Licensed operators in the province handled roughly CAD 98.3 billion in wagers during the 2025 calendar year, up 26%, generating about CAD 4 billion in gross gaming revenue before the province's 20% tax — a 34% increase, and roughly CAD 807 million for the treasury. Cumulative operator revenue since the market opened in April 2022 has passed CAD 10 billion. Just under 50 operators run more than 80 gaming sites, and active player accounts reached 1.27 million by the end of 2025.
That is a large and growing pool of commission to compete for. It is also the most constrained advertising environment in North America.
The compliance liability sits with the operator
Ontario does not license affiliates separately. There is no affiliate registration and no affiliate certificate. Instead, the Alcohol and Gaming Commission of Ontario (AGCO) makes the operator answerable for the conduct of every third party it contracts with, while iGaming Ontario handles the commercial agreements.
The practical effects are significant. Under the Registrar's Standards for Internet Gaming, third parties must behave as though bound by the same rules as the operator, and an operator may not work with a marketing affiliate that also promotes gambling sites serving Ontario without registration — which forces publishers to choose between the regulated market and the grey one. Since February 2024, athletes and celebrities have been barred from gambling advertising altogether, other than for responsible-gambling messaging.
The most commercially significant rule is the restriction on inducements. Bonuses and credits cannot be advertised to the general public; they may appear only on an operator's own channels or go to players who have actively opted in. That removes the single most effective conversion device the affiliate model relies on elsewhere, and pushes the competitive ground toward review depth, licensing transparency and payment detail instead.
Similar forces are visible in other markets. Better Collective attributed part of its revenue-share weakness to Brazil's prohibition on welcome bonuses, which it said redirected users towards unlicensed sportsbooks. Gambling.com Group cited a higher-than-expected gaming duty in the UK, and new rules in Finland curtailing performance marketing, when it set 2026 guidance.
Compliance is not overhead in this industry. It is a pricing input.
The bigger threat is arriving through search
Every structure described above assumes the same thing: that a reader clicks a link.
Pew Research Center analysis of the browsing behaviour of 900 US adults found that users clicked a traditional search result on 8% of visits to pages carrying an AI-generated summary, against 15% on pages without one — close to half the click-through rate. Clicks on links inside the summaries themselves were rarer still, at 1% of visits. Nearly six in ten participants encountered at least one AI summary during a single month.
For a business whose entire asset base is ranked pages, that is a structural problem rather than a cyclical one. It also explains the response: sports data subscriptions, content licensing deals with mainstream publishers, distribution partnerships on social platforms, paid acquisition and app products. Each is an attempt to own an audience relationship that does not route through a search results page.
What the casino affiliate model teaches other industries
Performance marketing is regularly presented to smaller companies as the sensible alternative to paying for advertising upfront — the pay-after-the-sale model businessabc has covered for SMEs. Gambling affiliates run the most developed version of that idea anywhere, and their experience is instructive in three ways.
First, whoever defines the payout base holds the power. If the counterparty calculates the number your percentage is applied to, the deduction schedule is the real negotiation, not the rate.
Second, deferred income transfers working capital from the buyer to the publisher. That is comfortable when volumes are stable and painful when they are not.
Third, a channel that supplies most of your traffic is a concentration risk, however well it has performed. The listed affiliates spent a decade optimising for one distribution channel and are now spending heavily to reduce their dependence on it.
Repricing, not collapse
None of the published numbers suggest the model is finished. Better Collective is guiding to organic revenue growth of 7% to 12% for 2026. Gambling.com Group remains cash-generative. Ontario's market is still expanding at a double-digit rate — and a regulated market with disciplined advertising rules arguably needs credible comparison publishing more than an unregulated one does.
What is changing is the price of the inputs. Traffic costs money now. Compliance costs money. And payment for delivering a customer increasingly arrives slowly, in instalments, and only if that customer stays.
That is the profile of a maturing industry rather than a failing one. It is simply a much harder business to run than it was three years ago.
