Prediction markets are calling who will control the Senate. On 20 August 2026, traders priced a Republican Senate at 53%, with five races too close to call:
Alaska
Iowa
Michigan
Ohio
Texas
Republicans hold the chamber 53-47 and defend 22 of the 35 seats on the ballot on 3 November 2026.
Prediction market traders read fundraising totals, polls, and primary results. None of that measures the cultural perspectives that actually decide how a person votes.
