How Big Is the Black Market: Traffic Data and Revenue Estimates

Estimating the precise size of an illegal market is inherently difficult, but the data points are consistent enough to draw a clear picture. An estimated 9.4 million pounds of Grand National turnover in 2025 — about 3.8% of the approximately 250 million total — went through unlicensed operators. That is from one race on one day. Scale that across the entire racing calendar and the numbers become significant.

Grainne Hurst, CEO of the Betting and Gaming Council, has been direct about the nature of these operators. She describes them as parasites that pay no tax, ignore safer gambling obligations and contribute nothing to the levy that funds British racing. The language is forceful, but the substance is accurate: unlicensed operators sit entirely outside the regulatory framework. They do not pay the 10% levy on gross gaming yield. They do not contribute to the 108.9 million pounds that funded prize money, integrity and welfare in FY2024-25. They do not comply with self-exclusion schemes, deposit limits or responsible gambling tools.

The 522% traffic growth coincides with the introduction and tightening of affordability checks by the UK Gambling Commission. Since February 2025, the threshold for enhanced checks sits at 150 pounds in net deposits per month. The Racing Post’s Big Punting Survey — roughly 10,000 respondents — found that 23.7% of bettors had experienced affordability checks in 2025, up from 16.6% in 2023. Among higher-staking punters, a third admitted to using unlicensed operators. The connection between tighter regulation and black market growth is not proof of causation, but the correlation is hard to ignore.

What Bettors Risk on Unlicensed Sites: No Payouts, No Protection

The appeal of unlicensed operators is obvious: no account restrictions, no affordability checks, higher limits and sometimes more generous odds. The risks are less visible until something goes wrong — and things go wrong regularly.

An unlicensed operator has no obligation to pay you. If you win a large amount and the operator decides not to honour it, you have no dispute resolution process, no ombudsman, no legal standing in UK courts. Your deposit is not held in segregated funds. If the operator shuts down or moves to a different domain (which happens frequently), your balance disappears with it.

There are no responsible gambling protections. No self-exclusion, no deposit limits, no reality checks. If you develop a problem, there is no safety net. The operators are not subject to the advertising standards that apply to UKGC-licensed companies, which means they can target vulnerable customers with aggressive promotions that would be prohibited in the regulated market.

Ian Murray, the DCMS Minister, addressed this directly in a Westminster Hall debate, stating that the government intends to pursue unlicensed operators through legislative, regulatory and financial means. The Chancellor’s budget allocated 26 million pounds to the Gambling Commission specifically to tackle the black market. But enforcement against offshore operators is slow, and new sites replace shut-down ones within days.

The regulatory gap also means no data protection. Unlicensed operators may sell your personal information, use your payment details for unauthorised transactions or share your data with other unregulated entities. The UKGC’s data protection requirements do not apply to operators it does not regulate. I have spoken to punters who discovered fraudulent transactions on the cards they used to deposit with unlicensed sites — and they had no recourse because the operator existed beyond the reach of UK law.

Government Response: 26 Million Pounds for Enforcement

The scale of the black market has forced a political response. An open letter signed by over 400 leaders of British racing warned the government that the unregulated market threatens both the sport’s finances and the effectiveness of harm prevention measures. The letter described what the signatories called an unprecedented state intrusion — referring to the affordability check regime — that has dismayed millions of racing enthusiasts while simultaneously feeding the black market.

The government’s primary response has been financial: 26 million pounds for the Gambling Commission to expand its enforcement capabilities. The DCMS has also signalled legislative interest in giving regulators stronger powers to block unlicensed websites and disrupt payment processing to offshore operators. Whether these measures will be effective against a market that operates across jurisdictions and can relocate infrastructure quickly remains to be seen.

The enforcement challenge is structural. Unlicensed operators typically register domains in jurisdictions beyond UK legal reach, use cryptocurrency payment channels that bypass traditional banking controls and market themselves through social media accounts that can be recreated within hours of being taken down. Blocking website access through internet service providers is technically feasible, but punters with basic technical knowledge can use VPNs to circumvent blocks. The 26 million pounds is a start, but closing the black market requires international cooperation that moves far slower than the operators themselves.

For punters, the practical message is unambiguous. Every pound placed with an unlicensed operator is a pound that carries no payout guarantee, funds no prize money, supports no welfare programme and sits outside every protection the regulated market provides. The frustrations with affordability checks and account restrictions are real — I hear them from serious bettors constantly. But the alternative of betting in an unregulated market trades one set of problems for a far more dangerous set. The regulated market has flaws. The black market has none of the features that make betting safe.

Frequently Asked Questions

How can I tell if a horse racing betting site is unlicensed?
Check the UK Gambling Commission"s public register. Every operator licensed to accept bets from UK customers is listed with a licence number. If the operator is not on the register, it is not licensed. Unlicensed sites often lack a visible UKGC licence number in the footer, may be registered in offshore jurisdictions and sometimes offer unusually high deposit limits or no identity verification.
What happens if I win on an unlicensed betting site?
There is no guarantee you will be paid. Unlicensed operators are not bound by UK regulations on fund segregation, dispute resolution or payout timescales. If the operator refuses to pay, you have no recourse through the Gambling Commission, no access to an alternative dispute resolution provider and limited legal options since the operator sits outside UK jurisdiction.
