Sport Prediction: Every League, Every Major Event, One Order Book

Sports prediction markets — real-time odds across every league

Sport on Polymarket covers the NBA, NFL, MLB, NHL, MLS, top European football leagues (Premier League, La Liga, Serie A, Bundesliga, Champions League), tennis majors, Formula 1, MotoGP, UFC title fights, and the Olympics on a rolling basis. On PolyGram you trade this full catalogue through a mobile-first interface with UK-localised formatting.

Contract types

Every sports contract is binary — YES / NO. Price in cents equals implied probability. Match winners, series winners, season champions, MVP, coach of the year, playoff advancement, specific statistical milestones. Long-tail: specific player prop aggregates, end-of-season standings, transfer outcomes.

Why prediction markets instead of a sportsbook?

No house edge. Trading the same contract at the same price every other trader sees means you start without a built-in disadvantage. On premium events (NBA Finals, Super Bowl, Champions League final), that’s often the difference between profit and break-even.

Live trading

Order books remain liquid into the closing minutes on most markets. Prices respond in real time to in-game events, injuries, and momentum. Polygon block times drive execution latency — typically 2-3 seconds end-to-end.
