Trump’s extensive 2026 midterm endorsement activity, delivered primarily through Truth Social statements, continues to shape trader views on recipients in Senate, House, and gubernatorial races. As of mid-September, the president has issued dozens of endorsements with a reported 96% primary success rate, including recent slates backing candidates such as Barry Moore and Tommy Tuberville in Alabama, alongside heavy spending by affiliated super PACs exceeding $138 million in targeted advertising for roughly 50 contests. Some gubernatorial picks have faced primary setbacks, while Senate and House support has largely aligned with incumbents or early frontrunners. Upcoming general-election voting in November and any additional late-cycle announcements remain key variables that could shift probabilities.
