Polymarket US launched parlays to the public on the same day as Kalshi started charging market makers on its own multi-leg bets.
Despite self-certifying parlays in May, Polymarket only started testing the product for its CFTC-regulated U.S. site on Aug. 5. Testing volume then ramped up starting on Aug. 12. Through its beta test, API users — usually more sophisticated market makers or professional traders — could trade parlays but regular customers using the Polymarket U.S. app could not. Polymarket US does not currently have a live desktop site for trading.
With a new app update that went live Thursday, parlays are now available to ordinary Polymarket US customers.
