Matchbook launched UK prediction market in January ahead of US plans
Matchbook, a sports betting exchange majority-owned by Zeljko Ranogajec and operating for 20 years, debuted 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 shifted from fractional odds to probability-based Yes/No percentages for binary outcomes, mirroring U.S. prediction-market design. Its UK launch runs under Matchbook's existing UK Gambling Commission exchange licence and includes 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 underpins Matchbook's planned U.S. expansion. Any approval would give the venue federally licensed status, directly challenging Kalshi and Polymarket's position in U.S. sports event contracts.
Matchbook's U.S. entry, routed through RSBIX LLC, targets federally regulated prediction markets.
