Illegal Betting and the UK Pool Economy: How the Black Market Drains Exotic Pool Liquidity
Available in US
Here is a number that should alarm every pool bettor in the UK: unique visits to 22 of the most popular non-UK-licensed betting sites that take bets on British racing grew by 522% between 2021 and 2024. That is not a typo. Five hundred and twenty-two percent. Every one of those visits represents potential betting volume that bypassed the regulated market – and by extension, bypassed the Tote pools from which your exotic dividends are paid. The illegal betting market is not a side issue for wheel bettors. It is a direct drain on the liquidity that determines your returns.
IFHA Research: 522% Growth in Unlicensed Site Traffic
James Porteous, Head of Research at the IFHA Council on Anti-Illegal Betting, documented the scale of the shift. In four years the total number of unique visits to those 22 sites grew by 522%. Total traffic on unlicensed sites rose 131%, while traffic to licensed sites grew by just 25%. The disproportion is stark: the illegal market is expanding five times faster than the legal one.
By January to September 2024, more than 600,000 unique visits per month were being recorded on those unlicensed platforms. A separate BHA survey of over 14,000 respondents found that 10% of racing bettors actively use illegal operators. One in ten. That is not a fringe problem – it is a structural leakage of betting volume from the regulated ecosystem.
The reasons behind the migration are multiple: higher credit limits, fewer identity checks, better odds on some markets, and the absence of affordability interventions that some bettors find intrusive. Online stakes on UK racing fell by 1.6 billion pounds over two years, and the IFHA data suggests a meaningful portion of that lost volume migrated rather than disappeared.
How Diverted Volume Shrinks Legitimate Pool Sizes
The Tote’s exotic pools are funded entirely by the stakes placed into them. No house money, no external subsidy – the pool is the sum of all bets. When a bettor who would have placed 20 pounds into a Trifecta pool instead places that 20 pounds with an unlicensed offshore operator, the Tote pool shrinks by 20 pounds. After the 25% deduction, the net pool available for dividend distribution shrinks by 15 pounds.
Scale that across 600,000 monthly unique visits to unlicensed sites, each potentially representing multiple bets, and the cumulative drain on legitimate pool liquidity is substantial. Not all of those visits involve exotic bets – many will be Win and Each-Way betting – but the principle applies across all pool types. Every pound diverted is a pound missing from the dividend calculation.
The consequences for wheel bettors are tangible. Thinner pools produce more volatile dividends. A pool with 50,000 pounds generates a materially different dividend structure from a pool with 35,000 pounds on the same race. The 25% deduction takes a larger bite from the perceived dividend when the pool is smaller, and the chance of a winning combination returning less than the ticket cost increases.
I have noticed the effect most at midweek evening meetings, where pool sizes have contracted noticeably over the past three seasons. The races have not changed – same types, same field sizes, same quality of competition – but the money in the pools has thinned. Whether that is attributable to illegal betting, affordability checks, general market decline or some combination of all three is impossible to isolate. But the result for my Trifecta dividends is the same: lower payouts on similar results.
There is an irony here that is not lost on pool bettors. The illegal market thrives partly because regulated operators face higher costs from the Levy, tax, and compliance requirements. Those costs are passed to bettors through deductions and margins. The higher the regulated cost, the more attractive the unregulated alternative becomes, and the more volume leaks to the black market. Each round of the cycle makes the legitimate pools a little thinner and the exotic dividends a little weaker. It is a feedback loop that benefits nobody except the unlicensed operators.
Industry and Regulatory Response
Brant Dunshea, the BHA’s Chief Executive, has framed the issue as a regulatory balance problem: adding more red tape to an already highly regulated sector will only fuel a significant rise in illegal betting, deprive horseracing of funding, and prevent the Government collecting millions in taxation. The argument is that excessive regulation of the legal market pushes volume to the unregulated one, where there is no Levy contribution, no consumer protection, and no pool participation.
The BHA and the Betting and Gaming Council have both called for proportionate regulation that allows safe bettors to operate without friction. Dunshea separately stated that gambling regulation should be balanced, with those who are betting safely on racing allowed to do so without interruption. The tension between player protection and market volume is the central policy challenge, and there is no easy resolution.
For pool bettors specifically, the policy direction matters because it determines how much money flows into the Tote’s pools over the coming years. If regulatory friction drives more volume offshore, pool sizes contract further and exotic dividends deteriorate. If the regulatory environment stabilises and diverted bettors return to licensed operators, pool liquidity recovers. The outcome is uncertain, but the trend through 2024 and into 2025 has been in the wrong direction for anyone who depends on deep pools for their wheel bet returns.
As a wheel bettor you cannot control the regulatory environment, but you can control where you play. Concentrate your exotic bets on meetings with the deepest pools – Premier fixtures, festivals, World Pool races – where the liquidity drain from illegal betting has the least proportional impact. Avoid thin midweek pools where even a modest diversion of volume can visibly compress dividends. The black market is a headwind for pool betting in the UK, and the most practical response is to play where the wind blows least.

How does illegal betting reduce UK Tote pool sizes?
Bettors who place wagers with unlicensed operators instead of licensed ones remove their stakes from the regulated market. Those stakes do not enter Tote pools. The cumulative effect of hundreds of thousands of monthly visits to unlicensed sites is a measurable reduction in the money available for pool distribution, leading to thinner pools and more volatile dividends on exotic bets.
What proportion of UK racing bettors use unlicensed operators?
A BHA survey of over 14,000 respondents found that 10% of racing bettors actively use illegal operators. IFHA research showed more than 600,000 unique monthly visits to 22 popular unlicensed sites between January and September 2024. The scale suggests the issue is not limited to a small fringe but represents a significant share of total UK racing betting activity.
