Kalshi CEO: Polymarket is not the main competitor; CME, Robinhood, and DraftKings pose a greater threat.

According to ME News, on June 18 (UTC+8), Kalshi CEO Tarek Mansour stated in an interview with Front Office Sports that he does not consider Polymarket a major competitor, but is more concerned about the threats posed by CME Group, Robinhood, and sports betting operators. According to data from Bank of America analysts, Kalshi holds approximately 91% of the regulated prediction market share in the US, holding about $1 billion of the industry's approximately $1.6 billion in open interest, and listing on approximately 97% of the active markets. Kalshi's trading volume over the past 30 days was approximately $9.8 billion, close to Polymarket's $9.9 billion. CME launched FanDuel Predicts in partnership with FanDuel last December; Robinhood, after building its prediction market on the Kalshi exchange in 2025, has begun migrating some contracts to its Rothera platform, which partners with Susquehanna. Mansour called for Polymarket to be brought under regulatory oversight, stating that insider trading cases on its offshore platform are harming the entire industry. The CFTC released a 267-page rule proposal on June 10, suggesting that it would allow most sports contracts but prohibit in-game betting and pre-game college sports. A 45-day public comment period is underway. (Source: ME)
