Cheaper isn't the same as underpriced
Both exchanges can be too expensive at once. Pro compares each price with the sportsbooks' fair odds and alerts you when either exchange sells a team below what it's worth.
How the comparison works
Prices
We use the price you'd pay to buy each side right now (the ask) on both exchanges. A 60¢ contract pays $1 if that team wins.Fees
Both charge a fee of roughly 7% × price × (1 − price) per contract, highest near 50¢. Polymarket US's rate is slightly lower. The "Buy on" column already includes both.Why prices differ
They're separate markets with different traders. News, big orders and thin late-night books move one before the other, so gaps of a few cents are common.Before you buy
Prices change by the minute and the cheapest price may only cover a few contracts. Check the live price on the exchange, and see our combo checker before buying parlays.Not affiliated with Kalshi or Polymarket. For information only, not financial advice. 21+.
