Resolution criteria

• Each of the listed players resolves YES if that player appears as one of the four semifinalists in the 2025 US Open Women’s Singles main draw; players resolve NO otherwise. Verification: the official US Open women’s singles draw/results page or PDF and/or the WTA tournament page.

(en.wikipedia.org, wtatennis.com)

• “Other (Any Player Not Listed Above)” resolves YES if at least one of the four semifinalists is not among the named answers; resolves NO if all four semifinalists are from the listed options. For clarity's sake, those listed players are:

  • 🇧🇾 Aryna Sabalenka (1)

  • 🇵🇱 Iga Swiatek (2)

  • 🇺🇸 Coco Gauff (3)

  • 🇺🇸 Jessica Pegula (4)

  • 🇷🇺 Mirra Andreeva (5)

  • 🇮🇹 Jasmine Paolini (7)

  • 🇺🇸 Amanda Anisimova (8)

  • 🇰🇿 Elena Rybakina (9)

  • 🇺🇸 Emma Navarro (10)

  • 🇨🇿 Karolina Muchova (11)

  • 🇨🇭 Belinda Bencic (16)

  • 🇯🇵 Naomi Osaka (23)

  • 🇺🇦 Marta Kostyuk (27)

• Edge cases: being that the tournament has already begun, it is unlikely there will be any players that resolve N/A. If a player has to retire due to injury before the semifinals, so be it, that player will resolve NO. If a player retires during the semifinal matches, that makes no difference to this market. As market creator, I reserve the right to N/A if there is some sort of unforeseen extraordinary circumstance.

Background

• Event dates/venue: Aug 24–Sep 7, 2025, USTA Billie Jean King National Tennis Center (NYC). The 2025 edition uses a 15-day format starting on a Sunday. Women’s semifinals are scheduled for Thu, Sept 4 (evening). (usopen.org, espn.com, wtatennis.com)

Considerations

• Only the Women’s Singles main draw counts (not doubles, mixed, or juniors).

• Inspired by @105du's excellent men's semis market.
