Why are the prices different?
Kalshi and Polymarket are separate exchanges with different traders and fees, so Blues and Red Wings can trade at different prices on each for minutes at a time. If buying Blues on one venue and Red Wings 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.
