Robinhood’s new derivatives platform lets users bet on the winner of a WTA 125K match with a simple yes/no contract.
Key points
- Robinhood’s prediction market lets users wager on a single tennis match outcome with binary contracts priced in cents.
- The contract settles within an hour of the match’s result, unless the match is cancelled or postponed, in which case a fair‑price settlement applies.
- Eligibility rules prohibit insiders and anyone with material non‑public information from trading.
Robinhood Derivatives, LLC has listed a binary contract on the upcoming WTA 125K Cali round‑of‑32 match between Sofia Costoulas and Marina Bassols Ribera, scheduled for November 3, 2026. The contract asks traders to predict which player will win after the first ball is played, with a payout of $1 per contract if the prediction is correct.
The market operates 24 hours a day, except for a two‑hour maintenance window on Thursdays from 3 AM to 5 AM ET. Prices currently show a bid of 33 ¢ and an ask of 34 ¢ for a “Yes” contract (Costoulas wins), while a “No” contract (Bassols Ribera wins) trades at a similar range. Trades can be closed before the event resolves, and payouts are typically processed within an hour of the match’s conclusion.
How the contract works
If the match does not take place—due to injury, walkover, or cancellation—the contract will settle at a fair price according to Robinhood’s rules. Should the match be postponed, the market will stay open and close after the rescheduled contest, provided it occurs within two weeks of the original date.
Robinhood restricts trading for current players, coaches, staff, and anyone with non‑public material information about the match. Employees of the league, team owners, their immediate families, and individuals employed by the source agencies are also barred from participating, in line with standard event‑contract regulations.
