This index measures market-implied expectations of Republican control of the U.S. Congress following the 2026 midterm elections. It aggregates prices from a focused set of legislative outcome markets that resolve favorably under Republican-aligned scenarios, specifically Republican control of the House and Senate, while offsetting exposure to Democratic control of each chamber. By synthesizing probabilities across both chambers, the index reflects the market’s aggregate assessment of Republican legislative control rather than the likelihood of any single chamber outcome in isolation. Movements in the index capture shifts in perceived Republican strength as political conditions evolve, including presidential approval trends, economic conditions, candidate quality, fundraising, and historical midterm dynamics.
