Why are the prices different?
Kalshi and Polymarket are separate exchanges with different traders and fees, so Mavericks and Spurs can trade at different prices on each for minutes at a time. If buying Mavericks on one venue and Spurs on another costs less than $1 after fees, the difference is yours whoever wins, as long as both venues settle the game the same way. Read the step-by-step guide and the risks.
Prices are each venue's best ask: the price to buy that team, before fees, at whatever size is for sale. A price of 45¢ means the market puts it at about 45%; each contract pays $1 if that team wins. Venues can settle a postponed or suspended game differently; check both venues' rules before trading. Not financial advice. ArbTrader isn't affiliated with Kalshi and Polymarket.
