Matchbook Rolls Out In The UK As It Gears Up For A US Prediction Market Entry

Matchbook, a long-running sports betting exchange, is preparing to launch a new prediction market platform in the United Kingdom in January 2026, with a United States rollout targeted for March. The company will first test its technology and user experience in the UK before trying to break into the US prediction market arena led by Kalshi and Polymarket.

Unlike a traditional sportsbook, Matchbook operates as a betting exchange, directly matching customers who want to bet for or against an outcome and charging a small fee on each trade. For its new product, the firm will present markets as simple “yes” or “no” contracts priced as probabilities, rather than the fractional odds used in conventional sports betting.

Interim CEO Ronan McDonagh says the model should feel familiar to existing exchange users while being easier for newcomers to understand, potentially opening the door to a broader audience. Matchbook is operated by Triplebet Ltd., a Guernsey-registered company that has run its sports exchange for two decades.

Matchbook is majority-owned by Zeljko Ranogajec, a reclusive professional gambler originally from Australia who was recently identified by the Wall Street Journal as a key figure in a 2023 campaign that secured a $57 million Texas Lottery jackpot. His reputation for complex, data-driven betting strategies adds intrigue to Matchbook’s prediction market play.

To enter the US, Matchbook is partnering with RSBIX LLC, which filed with the Commodity Futures Trading Commission in September and is led by lawyer Jeff Ifrah, a former defense attorney for Donald Trump. McDonagh has indicated Matchbook is open to co-branding with a larger US name, arguing that its exchange experience, technology, and liquidity will let it compete from day one.
