ADI Predictstreet Launches Prediction Markets in the UK with Matchbook

ADI Predictstreet has launched its prediction market platform in the UK via a partnership with Matchbook, crossing over with the start of the FIFA men’s World Cup.

ADI Predictstreet launched earlier this week, and is the official prediction markets partner for the World Cup. However, the platform on its own website is unavailable to UK users.

ADI was granted a license by the government of Gibraltar, a British overseas territory, in early April, but it is not licensed directly by the Gambling Commission, and has effectively secured a carriage deal with Matchbook.

In January, Matchbook’s parent company, Triplebet, became the UK’s first official prediction market operator when it repackaged the sportsbook at its EasyBet brand as a prediction market.

Predictstreet.matchbook.com is now listed among the domain names under Triplebet Limited’s Gambling Commission license. Matchbook itself operates as a peer-to-peer betting exchange.

Prediction market furore

Prediction markets have rapidly become popular across the US, in part due to the simplified “Yes/No” form of bets they offer. In the prediction market format, participants trade contracts where the payoffs are tied to a future event. The odds shift based on the betting activity from players.

Prediction market operators in the US have not limited themselves to sports betting, offering markets in areas such as culture, politics, crypto and economics. An example of a prediction market bet would be a player betting Yes or No on whether President Donald Trump will attend another football game this year. If 80% of bettors vote Yes, then the Yes bet will likely cost $0.80 and the No bet will cost closer to $0.20.

Kalshi and Polymarket have become two of the standout names in the space in the US, but several states have sought to take enforcement action against them.

While Minnesota is the only state to have placed an outright ban on prediction markets, more than 10 states are currently in litigation with prediction market operators, including Nevada and New Jersey.

Prediction markets in the US can be operated under a license from the Commodity Futures Trading Commission, and operators have not sought licensing from a state’s gaming regulator like with traditional sports betting. However, unlike Kalshi and Polymarket, ADI Predictstreet is only offering Yes/No markets on sporting events.

A unique position

Ronan McDonagh, Matchbook CEO, said:

“We already power EasyBet Predictions in the UK, and with the addition of ADI Predictstreet at Matchbook, we now operate the only exchange platform in the world running multiple licensed prediction market brands under a single regulatory framework.

“That is not a position any other operator can claim. Prediction markets represent the next evolution of what an exchange can be — accessible, intelligent, and genuinely more fair for the customer. Combining Matchbook’s two decades of exchange infrastructure with ADI Predictstreet’s FIFA World Cup 2026 partnership creates something genuinely new for sports fans in our markets. We are proud to be part of it.”

Regulatory differences

From a regulatory standpoint, Triplebet and ADI are very unlikely to face the same regulatory issues as those faced by Kalshi and Polymarket in the US. As with ADI Predictstreet, EasyBet only offers prediction markets on sporting events.

EasyBet is operated by Triplebet as part of a joint venture with EasyGroup, owner of airline EasyJet. With sports betting being fully regulated in the UK, the lines are not being obviously blurred, unless the Commission eventually decides to look into regulating that specific form of sports betting.
