Kalshi
This market focuses on determining which player will win the second set of a specific tennis match at the 2026 US Open. It reflects the competitive performance of the two athletes during that particular segment of play. The outcome depends entirely on the match's progression and final score in set two.
The market resolves based on which player wins the second set of the Arthur Fery vs Lorenzo Musetti match in the 2026 US Open Men Singles Round of 128. If the match does not commence due to injury, walkover, forfeiture, or cancellation before any ball is played, the market settles at a fair price. Postponements or delays allow the market to remain open until the rescheduled match concludes, with a two-week window for closure. In cases of retirement during the match, markets can resolve based on completed play; unresolved markets 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 through buying and selling contracts, which determines the current implied probability for each outcome. The top outcome’s chance reflects collective wisdom from active participants, adjusted continuously as new insights or betting activity emerge. Volume of $78,551 helps indicate how much interest the market is generating.
This market resolves around Aug 30, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The winner of the second set will be the sole determinant, based on official match results from accredited sports authorities and widely accepted score updates.
Injuries, weather delays, or sudden changes in player form could shift this market significantly before Aug 30, 2026. Key moments like early breaks of serve, high-profile coaching adjustments, or crowd support may also sway trader sentiment. Any last-minute news affecting either competitor’s readiness or strategy has the potential to move prices rapidly as the match approaches.
