What are Robinhood prediction markets?
Robinhood launched a prediction markets hub in 2025 through Kalshi and later added other exchanges. In June 2026 it began routing some contracts, starting with the football World Cup, to Rothera, a CFTC-licensed exchange and clearing house it co-owns with Susquehanna, while keeping other markets on Kalshi (Robinhood newsroom, June 2026). The contracts work like any event contract: a price between $0.01 and $0.99 that pays $1 if the outcome happens. What is an event contract?
Which should I use?
- In the US: Robinhood if you want event contracts next to your brokerage account; Kalshi or Polymarket US for a wider list of markets. Polymarket's international platform is not an option for new positions.
- Outside the US: Robinhood's prediction markets are US-focused; Polymarket's international platform, where allowed, has the deepest markets on world events.
- Anywhere: compare the same question's rules, deadline and all-in cost, not the brand.
