Analysis
Abdul El-Sayed is currently priced at 38% to win Michigan's 2026 Senate race, indicating markets view him as the frontrunner but not an overwhelming favorite. Mike Rogers at 24% and Mallory McMorrow at 25% remain competitive alternatives, suggesting substantial uncertainty about the general election dynamics. The probability reflects expectations about candidate viability, Democratic base enthusiasm, and Republicans' ability to mobilize against the Democratic nominee. Factors that could shift this include primary results, candidate fundraising trajectories, economic conditions affecting voter sentiment, and polling showing shifts in swing-voter preferences. Major catalyst points include the Democratic primary vote scheduled for early 2026 and subsequent general election polling, which will clarify whether the frontrunner maintains support or faces erosion to challengers.
- ›Democratic primary outcome will determine the nominee and their subsequent matchup strength against Republican opposition
- ›Polling trends in Michigan swing counties and among independent voters will influence viability calculations as the general election approaches
- ›Fundraising and campaign infrastructure levels for El-Sayed relative to Rogers and McMorrow suggest resource constraints that may affect voter reach
- ›Turnout expectations in Michigan's core Democratic areas versus suburban and rural regions will determine which candidate's coalition is viable
- ›National political environment and approval ratings of the incumbent administration will shape overall partisan lean going into November 2026

How we compute these odds
SimpleFunctions aggregates live prediction-market contracts from Kalshi and Polymarket. Each slug groups contracts that resolve on the same underlying event, identified by venue event_id.
For binary slugs, the headline probability is the liquidity-weighted mid-price across all bound contracts. For multi-outcome slugs (e.g. elections with 3+ candidates), the headline is the leader’s price; we never arithmetically average disjoint outcomes — that would produce a number with no real-world meaning.
Snapshots refresh every 5 minutes during market hours; daily aggregates are computed at 04:00 UTC. The 30-day sparkline is drawn from per-ticker daily means stored in market_indicator_daily; 24h delta and movement events are derived from the same source.
