Prediction market traders give Democrats 74% odds for Senate control
Kalshi traders one day before midterms estimate a three-in-four probability that Democrats will win Senate majority.
What This Means
Traders on prediction markets have moved to assign a 75% probability to Democratic Senate control, reflecting their collective assessment of electoral outcomes. This matters for markets because Senate composition shapes tax policy, regulation of financial services and energy, and judicial appointments—each with direct bearing on corporate earnings, sector valuations, and capital allocation.
