This market asks whether a woman will ultimately be the officially certified or sworn-in winner of the 2028 U.S. presidential election, not merely whether a woman wins a party nomination. A direct external market for a woman president was at 21%, while individual-winner projections put Alexandria Ocasio-Cortez at 12.7% and Kamala Harris at 4.0%; those candidate probabilities are only partial components of the broader outcome. October polling has Harris near the top of Democratic preference surveys, but the Republican field is led by men, notably JD Vance, and no nominee has been settled. With the race still more than two years away and early polling largely measuring name recognition, the exact-outcome external price is the best anchor, supporting a 21% quote.
The October 15–19 survey had Harris at 19%, Newsom at 14%, and Buttigieg and AOC at 13% each; Vance led the GOP field at 38%.
The Center Square’s October poll put Harris at 29%, with Newsom second at 14% and AOC at 9%; this is early preference polling, not a declared candidacy or settled nomination.
In the Oct. 2–5 survey of 2,553 U.S. adults, Harris received 30% of Democratic nomination preferences, ahead of Newsom (15%), AOC and Buttigieg (9% each); Vance led Republicans at 38%, followed by Rubio at 20%.
An October survey of women voters found 22% not open to voting for a qualified woman for president, while 65% said there are too few women in elected office.
Reporting describes Harris as retaining party affection and operational advantages while facing doubts about a repeat run; she has not announced a decision.
