According to CNBC, traders placed at least $1 million on Kalshi that Texas Gov. Greg Abbott would win reelection, and more than $1.4 million on a contract that Republicans would not secure control of the House of Representatives. Both trades were made on Nov. 3; Abbott lost to Democrat Gina Hinojosa by more than 700,000 votes. Prediction-market volume on midterm contracts across Kalshi and Polymarket more than tripled from the last week of October into midterms week.
