This market will resolve according to the individual who wins the CA-04 congressional district seat in the U.S. House of Representatives in the 2026 midterm elections. The midterm elections will take place on November 4, 2026. 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/).**Mike Thompson holds a clear lead in trader pricing for the CA-04 general election outcome, reflecting his incumbency, established fundraising edge, and broad party endorsements following the June 2 top-two primary.** In that contest, Thompson captured first place with roughly 41 percent while fellow Democrat Eric Jones advanced in second at about 22 percent, ahead of the leading Republican. The solidly Democratic district lean (Cook PVI around D+8) and the absence of a Republican on the November 3 ballot concentrate the race on the intraparty matchup. Thompson benefits from long tenure since 1999, moderate positioning, and support from figures including Nancy Pelosi and Gavin Newsom. Jones, a younger progressive challenger, has raised competitive sums but trails in name recognition and institutional backing. Forecasters rate the seat Solid or Safe Democratic, with limited late-cycle developments to shift the consensus beyond these structural factors.
