How to play The Rave
Yahoo Finance has ended its dedicated prediction market integration with Polymarket, cutting short a high-profile partnership less than a year after launch.
The investing and news site announced last week that it halted an arrangement in which it used Polymarket prediction market data for a dedicated hub on the website.
That relationship ended in April, just six months after it started. Yahoo Finance confirmed the end of that agreement to Bloomberg but noted that Polymarket remains an advertising partner.
What is The Rave?
“If a customer finds black market sites that have all their preferred betting and gaming options, convenience dictates they will transfer a broad range of their expenditure there. Consumer recycling means that banning or restricting key products has a broader distortive impact on the entire market,” the report noted.
Notably for highly engaging verticals light online slots, if players are receiving a smaller-than-expected RTP (return to player), or bonuses have been restricted, they could again transition to an illegal offering where there are no such restrictions.
As has been flagged in previous reports, Regulus highlighted that the top 1% of active customers accounts for almost 50% of black market revenue across Europe. This follows a similar trend across licensed gambling as the report highlights “online gambling is a consumer discretionary expenditure item. This means a large proportion of expenditure is concentrated into a relatively small number of players.”

The two related businesses are associated with entrepreneur Nic Brereton and had only recently started operating under their own licences. BresBet was licensed in February 2025, while Bet St George received its licence in December and launched in March this year.
At launch six months ago, Brereton told iGB that Bet St George would use the experience he gained applying advanced data models in the medical sector to improve the customer experience in betting.
“Sometimes what data tells you is uncomfortable because it’s challenging the norm,” he said at the time. “For me [it’s about] where we can make some marginal differences by using player data and challenging the perspectives of what the industry thinks should and does happen.”
