Kalshi CEO Mansour Says Polymarket Is Not His Main Rival

Kalshi CEO Tarek Mansour said he does not see Polymarket as his main competitor, arguing bigger trading and betting players pose a larger threat to his prediction market exchange. According to BeInCrypto, Mansour told Front Office Sports he is watching CME Group, Robinhood and sportsbook operators most closely, reframing a rivalry often cast as a two-horse race between Kalshi and Polymarket. Bank of America analysts estimate Kalshi has about 91% of the regulated US prediction market, with Polymarket second and Underdog third. Over the past 30 days, Kalshi traded about $9.8 billion versus Polymarket’s $9.9 billion, according to DeFi Rate.
