Note on affiliate channel economics

The affiliate channel is the oldest performance deal in online gambling and still the least transparent. Operators pay for delivered players, affiliates deliver them from content, comparison sites and traffic they control. This note works through who keeps the margin, because the answer is less obvious than the deal structure suggests.

Three deal shapes

Revenue share pays the affiliate a percentage of the losses generated by referred players, commonly for the lifetime of the account. CPA pays a one-time fee per depositing player. Hybrids combine a reduced version of both. The shapes allocate risk differently. Revenue share puts the affiliate on the operator's side of variance, a referred player who wins costs the affiliate income. CPA transfers all player-quality risk to the operator, which is why CPA deals attract volume games, incentivised sign-ups, bonus abusers and recycled player lists, and why operators police CPA cohorts hard in the first ninety days.

Where the margin sits

In the deals we can observe through listed affiliate companies' reporting, mature revenue share portfolios behave like annuities, cash arriving from players referred years ago at near-zero marginal cost. That is the margin, and it explains the consolidation wave, portfolios of old tags are worth buying. The operator's side of the ledger is heavier than it looks, revenue share liabilities survive market exits, brand migrations and even the affiliate's own sale of the tag. Several operators have discovered in due diligence that their cheapest historical channel is their largest forward liability.

The sub-affiliate problem

Between the operator and the traffic there is often a chain, an affiliate network, a media buyer, a sub-affiliate program. Each link takes a cut, and each link removes visibility. An operator paying a headline network sees an aggregate, not the sources. The traffic may originate from channels the operator would never approve directly, misleading ads, incentive schemes, or bidding on the operator's own brand name. The chain makes attribution launder itself, by the time a player lands, the tag says only which network gets paid. Our July note takes up the brand-name end of that problem specifically.

Our read

The channel is not going away, it prices acquisition honestly in a way brand media cannot. But the economics reward opacity at every link below the top, and operators who cannot name their traffic sources are carrying risks they have not priced, regulatory, reputational and financial. The affiliates worth premium terms are the ones who can show their sources without being asked twice.
