Kalshi CEO Ranks Robinhood, CME and Sportsbooks as Top Prediction Market Threats
HOOD•Tarek Mansour, CEO of Kalshi, named Robinhood among three primary threats to his prediction market business, alongside CME Group and major sportsbook operators. Robinhood built its prediction markets hub on Kalshi’s exchange in 2025 and now routes World Cup and baseball contract flow to its Rothera venue.
1. Kalshi CEO’s Competitor Reassessment
Kalshi CEO Tarek Mansour stated that Polymarket is no longer his main rival and instead pointed to Robinhood alongside CME Group and leading sportsbook operators as the biggest competitive threats to his regulated prediction market exchange.
2. Robinhood’s Prediction Hub Development
In 2025 Robinhood launched its prediction markets hub using Kalshi’s underlying exchange infrastructure. It later began routing high-volume World Cup and baseball event contracts to its Rothera platform operated in partnership with Susquehanna.
3. Competitive Implications for Robinhood
Robinhood’s integration of event-based contracts taps into its vast brokerage user base, potentially increasing its share of prediction market volume. This expansion could pressure Kalshi on fees, product offerings and customer retention in the growing regulated sector.
