Prediction markets on Kalshi posted a 63% probability of Democrats winning both the House and Senate in the midterms, a reading posted on October 25, 2026. That reading reflects real money being placed by traders who stand to gain or lose depending on the outcome.
Unified government control has historically meant a cleaner runway for legislative priorities, which is why policy-sensitive sectors move in response to shifting odds well before Election Day. Traders are already repricing names exposed to potential shifts in defense spending and other government-directed budgets, meaning the rotation is underway now.
For investors sitting on the sidelines, the risk is that the market will have already priced in a sweep by the time votes are counted. Keeping an eye on defense contractors and other sectors tightly linked to congressional appropriations is where the signal is sharpest right now.
