About OddsOverlay
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.
WHAT YOU GET
- Real-time Polymarket odds on tweets that make testable claims
- AI-powered matching that understands context, not just keywords
- Categories: Politics, Crypto, Sports, Tech, AI, Business, World, and more
- Share cards as screenshots — post them, paste them, flex on quote tweets
WHAT WE DON'T DO
- We don't read your DMs
- We don't track you
- We don't modify tweets or inject ads
- We don't require an account
- We only read publicly visible tweet text on your timeline
100 matches/day included. Built by @LeverCRO — more at oddsoverlay.com
