A Robinhood‑hosted prediction contract reveals the market heavily backs Sofia Kenin to take the second set against Mika Stojsavljevic.
Key points
- The market priced Sofia Kenin at 99 ¢ versus Mika Stojsavljevic at 1 ¢, indicating strong consensus that Kenin would win Set 2.
- Contract settlement rules cover cancellations, postponements, and retirements, with fair‑price adjustments applied when necessary.
- Robinhood’s sports prediction contracts are closed to new trades once the event concludes, and payouts are $1 per correct contract.
- Eligibility restrictions prevent insiders and those with material non‑public information from participating.
Robinhood’s derivatives platform listed a prediction contract for the second set of the WTA Hong Kong Round‑of‑32 match between Mika Stojsavljevic and Sofia Kenin scheduled for November 4, 2026. The contract asked traders to choose which player would win Set 2, with the market now closed to new trades.
At the time the market closed, the price for a "Yes" contract on Sofia Kenin winning Set 2 was 99 ¢, while the equivalent contract for Mika Stojsavljevic was priced at just 1 ¢. In Robinhood’s pricing model, a price near 100 ¢ reflects a near‑certain outcome, suggesting that market participants overwhelmingly expected Kenin to take the set.
Market pricing and implied probabilities
The contract terms state that if the match does not start—due to injury, walkover, or other cancellation—the contract will resolve to a fair price determined by the exchange. Should the match be postponed, the market remains open until the rescheduled set is completed, and any retirement after play begins will be settled based on the portion of the set already played.
Because the event has already taken place, the market is now marked as closed and no longer tradable. Traders who held contracts at settlement would receive a payout of $1 per contract if their prediction was correct, less any applicable fees.
