The entrenched constitutional schedule for U.S. midterm elections, reinforced by longstanding federal statutes and unbroken historical precedent even amid wars and crises, drives the overwhelming trader consensus reflected in current market pricing. Bipartisan institutional norms and the absence of any active legislative or executive effort to alter the November timeline further anchor expectations. While probabilities above 90% leave limited room for disruption, realistic scenarios that could still shift outcomes include a severe national emergency such as widespread infrastructure failure or a constitutional crisis requiring congressional action, though no such developments are currently underway.
