Polymarket accuses Kalshi of espionage over perpetuals announcement
Polymarket has accused rival platform Kalshi of espionage, claiming Kalshi spied on Polymarket in order to announce perpetual contracts first. The allegation marks an escalation in competition between the two prediction market platforms.
A public accusation of espionage between two leading prediction market platforms signals deteriorating relations that could draw regulatory scrutiny or spawn litigation, and it highlights how fiercely the two are competing on derivatives-style product launches.
Polymarket and Kalshi's public espionage clash joins their already parallel defensive lines against Kentucky's AG and CME's courtroom challenge, binding the two rivals together as the most litigated and scrutinized pair in the prediction-markets sector.
