How to Read Polymarket Prices
Polymarket FAQ
What are the odds on Polymarket today?
Polymarket odds are live market prices: a contract trading at 72¢ implies a 72% probability the event resolves YES. The table above ranks today’s markets by 24-hour volume and flags the biggest movers, refreshed every 5 minutes.
How accurate are Polymarket odds?
Prediction-market odds have historically tracked real-world outcomes closely, especially in high-volume political and macro markets where liquidity is deep. Thin, low-volume markets are noisier — always check 24-hour volume before trusting a price.
Can US traders use Polymarket?
Yes. Polymarket serves US traders through Polymarket US, a CFTC-regulated exchange live since December 2025 — identity verification is required and availability varies by state, and it lists a narrower slate than the international book. We still treat Kalshi as the primary US venue for its all-50-states coverage and deeper US-listed slate.
Polymarket vs Kalshi — which has better odds?
Neither is universally better — the same event is often priced differently on each platform, and that gap is the opportunity. We track those cross-exchange mispricings live.
How do Polymarket prices work?
Polymarket contracts trade in USDC cents. A YES price of 72¢ means a 72% implied probability. If the event resolves YES, the contract pays $1 USDC. If NO, it expires at $0.
