Luck Reactor

What is Luck Reactor?

GREF is a cooperative network bringing together national gambling regulators across Europe and beyond to facilitate dialogue, exchange information and share best practice on regulatory strategies. 

Tim Miller, who resigned from the UK Gambling Commission earlier this year, has stepped down from the GREF board and has relinquished his role as treasurer. 

Miller served on the forum for several years and was a key UK figure during a period when the Gambling Commission implemented extensive reforms to online gambling regulation and affordability checks. GREF expressed its gratitude for Miller’s contributions during his tenure.

While the new figures underline the sheer scale of Britain’s regulated market, leading operator Entain is pressing the government for tougher action against black-market platforms.

Entain highlighted that 11 of 20 Premier League clubs currently hold sponsorship or advertising arrangements with gambling operators lacking a Gambling Commission license—up from government estimates of eight clubs during the 2025/26 season.

“The government made clear in February that it would bring in a ban and it should do so immediately,” said Entain CEO Stella David, noting that clubs entering new agreements had already been warned. “Inconvenience is not an excuse for inaction.”

Entain warned that a sharp rise in MGD could prompt customers to migrate out of the regulated market, estimating that up to £1 billion in gambling stakes could shift to the black market.

The company cited analyses from the Office for Budget Responsibility which suggested previous gambling tax rises had reduced expected tax receipts, including a £500m reduction in forecast receipts for 2029-30. This revenue, writes David, would flow to the black market. 

A new report commissioned by Euromat, and produced by Regulus Partners and Helios, has estimated that Europe’s black market has sustained a compound annual growth rate of 18% between 2019 and 2026, and will be worth up to €13 billion by the end of the year.
