OddsOverlay

See what prediction markets say about claims on X. Like Community Notes, powered by real money.

Tweets make claims. OddsOverlay shows you what money thinks. When someone on X posts about elections, crypto, AI, geopolitics, or anything with a prediction market — OddsOverlay quietly appears below the tweet with the real-time probability from Polymarket. No opinions. No pundits. Just what thousands of traders are betting with real money. HOW IT WORKS Browse X normally. OddsOverlay reads tweet text, matches it against thousands of active prediction markets, and shows the odds inline — styled like Community Notes, because that's where useful context belongs. Always on by default — you don't have to do anything. If you prefer, toggle it off and use Scan Now to check tweets on demand.
