Description

This event tracks a specific snapshot of public opinion regarding congressional control in the 2026 U.S. elections. It focuses on a single moment in time to capture the state of voter preference between major parties. The outcome depends entirely on the precise numerical difference in support measured at that instant.

Kalshi

The event resolves to Yes if, at exactly 2:35 PM ET on September 27, 2026, the VoteHub 2026 generic ballot margin (calculated as Democratic support minus Republican support, using a time-weighted methodology) falls within any of several defined ranges: below 7.9%, exactly 7.9% through 8.5%, or above 8.5%. No other conditions or thresholds affect the resolution; the market settles based solely on this specific numerical comparison at the designated timestamp.
