Each of the listed players resolves YES if that player appears as one of the four semifinalists in the 2026 U.S. Open Women's Singles main draw; players resolve NO otherwise. Verification: the official U.S. Open women's singles draw/results page or PDF and/or the WTA tournament page. Links:

"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:

Edge cases: for any players that do not appear in the main draw (withdrawing prior to the tournament for any reason), those players will resolve N/A. If a player plays at least one point in a main draw match, however, and THEN has to retire due to injury before the semifinals, 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.

Event dates: August 30 – September 13, 2026. Women's semifinals are scheduled for Thu, Sep 10.

Only the Women's Singles main draw counts for the purpose of this market (not doubles, mixed, or juniors).
