BlockBeats news, October 29: Polymarket launched five-minute cryptocurrency up-or-down prediction contracts on its regulated U.S. platform. The platform is operated by QCX LLC and regulated by the U.S. Commodity Futures Trading Commission (CFTC).

A correct prediction pays $1 per share, while an incorrect one pays zero, with a structure similar to binary options.
