Will the 2026 Midterm Elections happen as scheduled?

Prediction markets put the probability at 90%: Will the 2026 Midterm Elections happen as scheduled. Currently, markets see this as likely (90% YES). Trump’s Approval Rating Compared to Predecessors Facing Midterm Elections.

What’s Happening

With 90% of prediction market participants betting that the 2026 midterm elections will proceed as scheduled on November 3, 2026, the primary risk to the electoral calendar stems from a potential post-election dispute rather than a pre-election cancellation. A recent Los Angeles Times analysis highlighted a specific procedural landmine: if the election outcome is very close, Republican lawmakers could theoretically invoke unsubstantiated fraud claims to nullify results in enough House contests to deny Democrats control. This scenario, while not delaying the vote itself, raises questions about whether the midterm elections happen as scheduled in terms of their conclusive certification. The market’s 10% NO probability reflects this tail risk, though no sitting member of Congress has introduced legislation to postpone the date. [Los Angeles Times, Apr 26]

President Donald Trump’s approval rating, now hovering around 40% according to the Silver Bulletin, is a key factor driving the political context for the election. Newsweek reported that Trump is currently more unpopular than he was in 2018, when Democrats gained 40 House seats during his first midterm cycle. Historical patterns strongly favor the party out of power, and with Republicans holding a slim 53-47 Senate majority, Democrats are targeting the 35 Senate seats up for election—including special elections for the Ohio seat vacated by Vice President JD Vance and the Florida seat left by Secretary of State Marco Rubio. These structural advantages make it likely that the midterm elections happen as scheduled, as both parties have invested heavily in primary campaigns already underway in states like Oklahoma (primary: June 16), Colorado (primary: June 30), and Kansas (primary: August 4).

The procedural mechanics of the election remain on track, with state-level filing deadlines and primary dates already set. The New York Times has published detailed polling for Senate races in Oklahoma, Kansas, and Colorado, indicating that both parties are operating under the assumption that the midterm elections happen as scheduled. No state legislature has moved to alter voting dates, and the Help America Vote Act provides federal standards for election administration. The primary risk to the schedule would require an extraordinary event—such as a national emergency declaration or a constitutional crisis—neither of which has materialized. For now, the 90% YES probability reflects the absence of any credible legislative or executive action to delay the vote, with the 10% NO margin reserved for the certification dispute scenario outlined by the Los Angeles Times.
