The match outcome hinges entirely on the precise set score. All six possible scorelines across the best-of-five format are individually tracked for resolution.
This market resolves based on the exact set score of the match between Alexander Zverev and Karen Khachanov in the 2026 US Open Men Singles Semifinal. There are six possible outcomes: Zverev winning 3-0, 3-1, or 3-2 sets, or Khachanov winning 3-0, 3-1, or 3-2 sets. If the match does not occur due to injury, walkover, forfeiture, or cancellation before any ball is played, all markets resolve to a fair price. If postponed or delayed, markets remain open until the rescheduled match concludes within two weeks. In case of retirement, markets that can be settled based on completed play resolve accordingly, while others resolve to Fair Market Price at the Exchange's discretion. The Exchange bears no official affiliation with the governing league, and all trademarks remain property of their respective owners.
