This market will resolve based on whether Donald Trump announces that he will vote for or endorse the listed candidate in the election named in the title. If Donald Trump does not announce an endorsement by the day before the scheduled election at 11:59 PM ET, this market will resolve to "No". The resolution source for this market will be official information from Donald Trump or one of his representatives, or a consensus of credible reporting of Donald Trump's endorsement.Trump's endorsements have shaped Republican primary outcomes in the 2026 cycle, with endorsed candidates winning 97% of races decided so far across congressional, state legislative, and executive contests. Recent activity includes a slate of Florida endorsements ahead of the August 18 primaries, covering governor, U.S. Senate, and other offices, alongside selections in other states that have drawn trader attention on platforms tracking specific races. Key drivers include Trump's public statements on Truth Social, timing relative to filing deadlines and runoffs, and the pattern of support for incumbents or aligned challengers over establishment figures. Upcoming primaries and any late-cycle announcements could shift probabilities, as markets price the likelihood of particular candidates receiving backing before resolution dates. Trader consensus reflects observed influence in battleground and open-seat contests amid the broader midterm environment.
