(The Center Square) – Prediction markets spent three weeks heavily favoring Flávio Bolsonaro to be Brazil's next president. That collapsed Sunday night. Tuesday, the same markets take on the U.S. Senate.
Kalshi and Polymarket put Democratic control of the Senate at 70% and 73% as of Friday morning. Forecaster Nate Silver's model put it near 75% as of Oct. 29.
