California’s 11th congressional district, encompassing most of San Francisco, carries a Cook Partisan Voting Index of D+36 and has delivered overwhelming Democratic margins in recent statewide and federal contests. Nancy Pelosi’s retirement opened the seat, but the June 2026 top-two primary advanced only Democratic candidates—state Sen. Scott Wiener and Supervisor Connie Chan—to the November general election, with Republican contenders receiving under 6 percent combined. This structure and the district’s voter registration patterns have produced the current market pricing. A Democratic outcome could shift only under extraordinary circumstances such as a candidate’s withdrawal, party switch, or disqualification after the filing deadline, none of which have materialized.
Rules
This market will resolve according to the party of the candidate who wins the CA-11 congressional district seat in the U.S. House of Representatives in the 2026 midterm elections. The midterm elections will take place on November 3, 2026. A candidate's party will be determined by their ballot-listed or otherwise identifiable affiliation with that party at the time all of the 2026 House elections are conclusively called by this market's resolution sources. A candidate without a ballot-listed affiliation to either the Democrat or Republican parties will be considered a member of one of these parties based on the party with which they most recently expressed their intent to caucus at the time all of the House elections are conclusively called by this market's resolution sources. This market will resolve based on the result of the election as indicated by a consensus of credible reporting. If there is ambiguity, this market will resolve based solely on the official results as reported by the United States government, specifically the Federal Election Commission (https://www.fec.gov/).
