Matchbook to Launch UK Prediction Markets Ahead of US Entry

Matchbook, a sports betting exchange, is launching a prediction market platform in the UK as it prepares to compete with rivals Kalshi and Polymarket in the US.

The British debut in January will be a “road test” of its technology before Matchbook — registered in Guernsey — obtains US regulatory approval, which it expects as early as March, interim chief executive officer Ronan McDonagh said in an interview.
