Kalshi
This market focuses on determining which player will win the third set of a specific tennis match at the 2026 US Open. It reflects the competitive performance of the two athletes in a high-stakes Grand Slam tournament. The outcome depends entirely on the players' skills, strategies, and conditions during that particular set.
The market resolves based on which player wins the third set of the specified 2026 US Open Men Singles Round Of 128 match between Stefanos Tsitsipas and Arthur Fils. If the match does not commence due to injury, walkover, forfeiture, or cancellation before any play occurs, the market settles at a fair price. Postponements or delays allow the market to remain open until the rescheduled match concludes, with settlement occurring within two weeks after the match finishes. In cases of retirement during the match, markets that can be definitively settled based on completed play will do so, while unresolved markets will settle at a Fair Market Price determined by the Exchange. Kalshi disclaims any official affiliation with the governing league, and all trademarks remain property of their respective owners.
On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. On Kalshi, traders manually set prices for this market through buying and selling contracts that represent either player winning Set 3. The current implied chance reflects the collective assessment of participants about which player is more likely to take the set, adjusted continuously by market activity and any new information about player form or conditions.
This market resolves around Aug 30, 2026, with the outcome confirmed once the match result is verifiable from credible public reporting. The winner of Set 3 will be determined by standard tennis rules during the match, and the platform will update the market accordingly shortly after official confirmation of the set result.
Key signals that could shift prices in this market include player injuries, changes in serving performance, weather delays, or any strategic adjustments made during the match. High-profile breaks of serve, tiebreakers, or decisive momentum swings are especially likely to influence trader sentiment and shift the odds rapidly as the set progresses.
