The US Political Future Index (UPFI) provides a comprehensive, real-time measure of anticipated Republican versus Democratic political control across major US electoral offices. Built on prediction market data from Kalshi, UPFI aggregates market-based probabilities to deliver a forward-looking gauge of political sentiment and power distribution expectations.

UPFI exclusively uses Kalshi prediction market data, ensuring regulatory compliance through CFTC oversight and maintaining data consistency across all included markets.

The index employs a weighting methodology that reflects both political significance and market characteristics:

  • Category Weights: Presidential (40%), Senate (30%), House (20%), Gubernatorial (8%), Mayoral (2%)
  • Market Weights: Volume sensitivity, time to expiration, population representation, and inherent political impact

The index spans five major office categories across federal, state, and local levels, incorporating markets for Presidential elections, Senate races, House contests, Gubernatorial elections, and qualifying Mayoral races.

note: composite indices follow a 100 - (50 - weighted_probability) pricing, non-composite are simply probability on a democrat (0) to republican (100) scale
