The remote gaming duty hike from 21% to 40% in April is also expected to have a significant impact on the black market, with Regulus estimating it could drive the market to be worth up to €1 billion, as consumers choose illegal offerings to access unrestricted bonuses.
Other studies have made similar estimations. In June last year two thirds of bettors surveyed by YouGov said the tax increase, which will also hit online sports betting from next year, would drive them to play with unlicensed operators.
The UK has historically maintained a high channelisation rate due to it being particuarly mature with a huge competitive offering. According to the report, up to 1,491 licensed sites provides sufficient choice for engaged players.

That distinction also informs his view of the wider battle. Asked whether illegal gambling can actually be defeated, his answer is: “No, but you can make it very difficult for them.”
The objective, he argues, is to make it harder for operators to simply replace a blocked domain with another one. “If they knew there was a tool that would find those new sites as well, they might become more cautious.”

Beginning with the US presidential elections in November 2024, when prediction markets catapulted into mainstream culture, their rise has been undeniable.

Commercial sports betting generated just under $17 billion in nationwide revenue in 2025, which is why Davenport asserts that the “stakes of this case are exceptionally high”. Kalshi and Polymarket alone posted more than $45 billion in trading volume, which is similar but not identical to betting revenue, in August. That was a 15% decline from July, although that drop is attributed to the conclusion of the Fifa World Cup tournament that month per Yahoo! Finance.
