The core idea
A price is a probability.
On Polymarket, a market at 59¢ means the crowd thinks there's a 59% chance it happens. PolyWatch teaches you to read the world in odds — then shows you when those odds move.
How it works
Three taps from noise to signal.
Browse
Filter 10,000+ markets by Politics, Crypto, Sports, Tech or Culture — price, volume and momentum at a glance.
Watch
Star the questions you care about — or link your wallet and let the markets you actually hold drive the radar.
Get alerted
Eleven detectors watch 24/7 and ping you the moment something moves — with the price, not just a number.
The edge
Eleven signals. Thousands of markets. Zero manual scanning.
Our detectors run on every market, every minute — so you only look when something actually happens.
Odds Swing
Sentiment is shifting fast.
Something new happened — go find out why before the rest of the market catches up.
Whale
Big money just moved one side.
Follow the smart money — large players often know something.
Volume Spike
A dormant market woke up.
A previously-ignored question is suddenly in play.
Smart Money
A top-ranked wallet just took a position.
PolyWatch tracks the top-50 profit leaderboard. Follow any wallet and get pinged when it moves.
Arbitrage
YES + NO sell for less than $1 combined.
A complete set locks in the gap whatever happens — every opportunity verified against the live order book.
The real edge is the overlap — a whale and an odds swing pointing the same way. The Conviction Score does that math for you.
