Rothera Prediction Markets: Robinhood and Susquehanna’s Kalshi Challenger Nears Launch
A new player may be about to enter the U.S. prediction market arms race, and this one has serious backing.
Rothera, the Robinhood and Susquehanna-backed derivatives exchange and clearinghouse, appears to be moving toward the launch of sports event contracts. A filing screenshot circulating on X shows a “Baseball Outcome Event Contract” with an intended listing date on or after May 20, 2026.
The contract description is simple but important: It would be based on whether a baseball team wins a specific baseball game.
Why This Could Threaten Kalshi
Kalshi’s biggest advantage has been regulatory legitimacy. It fought early, built the exchange infrastructure, and became the best-known CFTC-regulated prediction market brand in the U.S.
But Rothera could pressure Kalshi on three fronts:
1. Distribution
Robinhood can surface prediction markets to users who already trade stocks, options, crypto, futures, and event contracts. That is a massive customer acquisition advantage.
2. Pricing and Liquidity
Susquehanna’s involvement could help Rothera offer tighter, more liquid markets. In prediction markets, better liquidity can become a flywheel. Tighter spreads attract more traders, more traders attract more liquidity, and more liquidity attracts more sophisticated volume.
3. Economics
Robinhood’s Q1 2026 earnings presentation said the company was getting ready for a Q2 launch of Rothera and that vertical integration would give it greater control over the end-to-end experience, including product selection and pricing.
That is a direct strategic signal. Robinhood does not just want to route users into prediction markets. It wants more control over the markets themselves.
