Prediction Market Volume Surges During Midterm Elections Amid High Accuracy Rates
Trading activity on prediction platforms Kalshi and Polymarket saw a significant surge during the midterm elections, with volume for election-related contracts more than tripling in the week leading up to the vote. Traders reacted in real time to shifting results, including heavy betting on Democratic control of Congress and the Texas gubernatorial race. While analysis shows that over 87% of election markets correctly identified winners with at least a 90% probability 24 hours before the election, experts remain divided on their efficacy. Political forecaster Nate Silver argued that market probabilities often merely converge toward existing statistical models rather than providing independent foresight. Despite the political interest, sports betting continues to dominate total volume across these platforms.
