**Democratic candidates in the 2026 midterm Senate and gubernatorial races face a national environment shaped by low presidential approval ratings and polling trends favoring the party in several battleground states.** The November 3 election serves as the resolution benchmark, with markets resolving based on whether each listed Democrat’s statewide vote share falls below Kamala Harris’s 2024 presidential performance in that state. Recent polls, including Marist surveys in Iowa, show Democratic challengers competitive or leading in key contests, while broader aggregates indicate Democratic advantages in Senate control probabilities. Resolution depends on certified vote totals from state election authorities, with any candidate removed from the ballot treated as receiving zero percent. Traders assess state-specific factors such as incumbency, turnout patterns, and regional swings against the 2024 baseline.
