This event tracks the precise set scores in a specific tennis match at the 2026 US Open. It focuses on whether either player wins by particular set margins, providing a detailed outcome-based perspective on the match.
The event determines whether the Mirra Andreeva vs Janice Tjen match in the 2026 US Open Women Singles Round Of 128 concludes with one of four exact set score outcomes: Mirra Andreeva winning 2-0, Mirra Andreeva winning 2-1, Janice Tjen winning 2-1, or Janice Tjen winning 2-0. If the match does not occur before play begins—due to injury, walkover, forfeiture, or cancellation—the market resolves to a fair price. Postponements or delays keep the market open until the rescheduled match concludes, with settlement occurring within two weeks. In cases of retirement during the match, any markets that can be settled based on completed play resolve accordingly, while unresolved markets settle at Fair Market Price, determined at the Exchange’s discretion. The Exchange disclaims any official affiliation with the governing league, and all trademarks remain the property of their respective owners.
