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.
