Matchbook plans UK prediction market debut in January ahead of US launch
Matchbook, a sports betting exchange majority-owned by Zeljko Ranogajec and operating for 20 years, will debut its prediction market platform in the United Kingdom in January 2026 before expanding to the United States as early as March, interim CEO Ronan McDonagh told Bloomberg. The Guernsey-registered platform will shift from fractional odds to probability-based Yes/No percentages for binary outcomes, mirroring U.S. prediction-market design. Its UK launch will run under Matchbook's existing UK Gambling Commission exchange licence and include a white-label version for easyBet. Parent Triplebet Ltd. and U.S. partner RSBIX LLC, led by former Trump defense attorney Jeff Ifrah, filed CFTC paperwork in September. McDonagh said Matchbook is open to partnering with a recognized brand for its American launch and expects to compete on day one due to its existing exchange technology, liquidity, and market-making partners.
RSBIX LLC's pending CFTC application now underpins two distinct platform launches: Matchbook and ADI Predictstreet. Any approval would instantly give both venues federally licensed status, directly challenging Kalshi and Polymarket's first-mover position in U.S. sports event contracts.
Matchbook's U.S. entry joins ADI Predictstreet's FIFA-linked platform with pending CFTC approval, both routed through RSBIX LLC as the sports-exchange sector converges on federally regulated prediction markets.
