UK Black Market Gambling Stakes Set to Double by 2028 According to New Forecasts

Independent analysis from H2 Gambling Capital projects that illegal black market gambling stakes in the UK will nearly double from £17bn in 2025 to over £33bn by 2028 and this growth would account for 19.2% of all online betting and gaming stakes during that period. The figures come at a time when industry groups are examining how proposed regulatory changes might influence player behavior and operator activity across both regulated and unregulated channels.

Key Projections from the Analysis

The forecast highlights a steady rise in stakes directed toward unregulated platforms and observers note that these operators currently handle significant volumes without contributing to UK tax revenues or implementing mandated safer gambling measures. Data indicates the black market share could reach nearly one fifth of total online activity by the end of the forecast window and this shift would occur alongside broader market expansion in the legal sector.

Stake volumes are expected to climb consistently each year with the analysis breaking down annual increments that lead to the £33bn figure and experts have pointed out that such growth reflects patterns seen in other jurisdictions where regulatory tightening coincided with increased migration to offshore sites. The 19.2% proportion represents a notable portion of overall stakes and it underscores the scale of activity occurring outside the oversight of the Gambling Commission.

Industry Concerns Over Upcoming Regulations

The Betting and Gaming Council has drawn attention to several policy developments that could accelerate movement toward unregulated operators and these include financial risk assessments scheduled for discussion at the Gambling Commission's 21 May board meeting along with potential increases in tax rates and additional restrictions on product offerings. Industry representatives argue that these measures when combined may reduce the appeal of licensed platforms for some players and push activity into channels that lack consumer protections or tax obligations.

Financial risk assessments in particular are viewed as a point where compliance costs could rise for legal operators and the Council has noted that higher operational burdens might narrow the competitive gap between regulated sites and those operating without UK licensing. Tighter rules on marketing and product design are also cited as factors that could influence player retention within the licensed market while unregulated sites continue to offer unrestricted options without equivalent safeguards.

Tax and Compliance Implications

Unregulated operators pay no UK gambling duties and this creates a structural difference in cost bases compared with licensed entities that must meet tax and regulatory requirements. The analysis suggests that any acceleration in black market growth would correspondingly reduce the tax base available to the Treasury from online betting and gaming activities and this outcome has been flagged by the Betting and Gaming Council as a material risk of the current policy trajectory.

Those who have examined similar regulatory shifts in other markets observe that players often respond to increased friction in legal channels by seeking alternatives that impose fewer checks or limits. The Council has emphasized that maintaining a balanced regulatory environment remains essential if the objective is to keep the majority of stakes within the licensed sector where consumer protections apply and tax contributions are collected.

Context Around the May Board Meeting

The Gambling Commission's board meeting scheduled for 21 May will consider proposals related to financial risk assessments and these discussions are expected to shape the next phase of enforcement and compliance standards. Stakeholders in the licensed industry have submitted views on how such assessments might be implemented without creating unintended incentives for players to migrate elsewhere and the outcome of that meeting will likely influence subsequent guidance issued to operators.

Broader policy discussions around tax rates and product restrictions are also ongoing and the Betting and Gaming Council has highlighted the need for coordinated timing across these initiatives. Evidence from the H2 Gambling Capital forecast is being referenced in these conversations as an indicator of potential market responses to cumulative regulatory pressure.

Conclusion

The independent forecast from H2 Gambling Capital provides a quantified projection of black market growth through 2028 and the Betting and Gaming Council has used this data to underscore risks associated with the regulatory pipeline including the 21 May board meeting and related tax and rule changes. Figures showing stakes rising from £17bn to over £33bn while reaching 19.2% of total online activity illustrate the scale of activity occurring outside licensed channels and these numbers continue to inform debates on how best to align regulatory objectives with market dynamics.
