A small cohort of high-value players still generates most of the revenue in online gambling, and that concentration is now the industry's central growth problem. The economics that made VIP schemes the sharpest instrument in operator marketing are the same economics regulators have set out to break.
Start with how skewed the base is. Patterns of Play, the largest study of British online gambling accounts, analysed 139,152 accounts from seven major operators over July 2018 to June 2019. It was commissioned by GambleAware and run by NatCen with professors David Forrest and Ian McHale at the University of Liverpool. The headline finding: the 5 percent of accounts with the highest losses produced at least 70 percent of gross gambling yield in every product category studied, from betting to virtual casino, live casino and slots.
A parallel NatCen analysis put it another way: the top 10 percent of accounts by amount staked delivered 79 percent of operator revenue, and the top 20 percent delivered just over 90 percent. Spend was also weighted toward deprivation, with a quarter of gaming losses coming from the fifth of accounts in the most deprived areas.
That is the whole business in one number. Growth in online gambling has never been about many people betting a little. It has been about a few people betting a lot.
What high-value players are worth
The VIP scheme is the machinery built around that fact. Operators identify their highest-spending accounts and attach a dedicated host, hospitality invitations, personal cashback, and individualised bonuses that the wider customer base never sees. The UK Gambling Commission's own high-value customer guidance describes these schemes as enhanced service reserved for customers of "enough commercial value" to justify it.
For a decade this was the most efficient marketing spend in the sector. A host managing a book of high-value accounts returned more per pound than any acquisition campaign, because the players were already there and already spending. The cost was reputational, and for years operators treated it as someone else's problem.
The rules that broke the model
The Commission ended that on 30 September 2020, with new rules in force from 31 October. Before granting VIP status, an operator now has to establish that the spending is affordable within the customer's disposable income, check for indicators of gambling harm and vulnerability, hold current evidence of identity, occupation and source of funds, and put a senior manager holding a personal management licence in charge of the scheme. Status is reviewed at least quarterly and suspended when the checks fail.
The impact was immediate. The Commission said the number of customers in VIP schemes had already fallen by 70 percent after its initial 2019 challenge to the industry, before the formal rules even landed. The enforcement record shows why it moved. Betway paid 11.6 million pounds for failings tied to VIP customers, including a VIP who deposited more than 8 million pounds and lost more than 4 million with no adequate source-of-funds checks, and another who lost 187,000 pounds in two days.
The affordability squeeze
The second blow is affordability, and it reaches deeper than VIP status. From 30 August 2024 the Commission introduced light-touch financial vulnerability checks at a net deposit of more than 500 pounds per rolling month, tightening to more than 150 pounds from 28 February 2025. These run on public data such as county court judgments, not bank statements, and are designed to catch financial distress before a loss cascade.
Above that sits a separate pilot of frictionless risk assessments for the highest-spending accounts, using credit-reference data. The Commission has reported that the large majority of checks in the pilot completed automatically, with only a small share of accounts, on the order of a few percent, flagged for further review. The point of the design is to make the friction invisible to ordinary bettors while still catching the outliers. We covered the mechanics for players in our explainer on UK financial risk checks, and the parallel constraint from deposit limits works on the same cohort.
The combined effect is that the exact accounts that generate the bulk of revenue are now the accounts wrapped in the most compliance. The high end of the book is no longer a growth lever an operator can pull freely.
Where the growth has to come from instead
Some operators have already rewritten the plan. Evoke, the group formerly named 888, repositioned its UK business toward lower-staking, higher-margin, recreational customers and away from dependence on high-spend players. In its 2023 results the group's UK and Ireland stakes fell 11.3 percent while betting net-win margin rose from 10.8 to 12.1 percent, and it set targets of 5 to 9 percent annual revenue growth with steady margin expansion.
That trade is the template. Revenue from a wide base of small, sustainable players is worth less per head but carries less regulatory and reputational risk, and it does not evaporate when an affordability rule tightens. It also forces a different marketing muscle, retention and cross-sell across a large base rather than white-glove management of a few hundred whales. Our analysis of the shift from acquisition to player retention traces where that spend is moving.
The tax side pushes in the same direction. With the UK Remote Gaming Duty rising to 40 percent, the margin on every player thins, and a book propped up by a handful of high-loss accounts is both the most profitable and the most exposed. The concentration that built the modern operator is now the single feature auditors, regulators and investors examine first.
Growth that survives an audit
The high-value player is not going away. There will always be customers who spend more than everyone else, and serving them well is legitimate. What has ended is the freedom to build a growth plan on them without scrutiny. The operators that treated VIP revenue as a compliance liability to be managed down, rather than a number to be defended, are the ones whose growth now reads cleanly on the page. The rest are running a model whose best quarter is also its biggest risk.
