U.S. Sports Betting Market Monitor – December 2025

The December edition of our U.S. Sports Betting Market Monitor is now live.

U.S. OSB continues to grow, with T12M GGR +16% through Oct-25 and net hold tracking toward record highs in 4Q25. At the same time, the FanDuel-DraftKings duopoly remains near a historic low (~64% GGR share), as challengers continue to close execution and scale gaps.

A central focus this month is prediction markets product. Our hands-on testing of Fanatics and DraftKings’ newly launched PM apps highlights meaningful differences in integration, UX, and PM-native tooling. And while Kalshi’s product remains ahead of both new offerings, the PM category remains nascent, and no clear product template has yet emerged.

Also inside:

  • A detailed Missouri OSB launch readthrough, including early Google Trends signals
  • An Evoke M&A analysis, assessing which U.S. buyers could realistically pursue European scale
  • Updated state-level performance, ROI mapping, and acquisition momentum trends
