Will Democrats win
Analysis
This probability represents the market's assessment that Democrats will win both Iowa and Ohio in the 2026 election cycle. At 35%, the Republican sweep scenario is currently favored, suggesting markets view these states as leaning Republican. The current level reflects historical voting patterns in both states—Iowa and Ohio have voted Republican in recent presidential cycles—combined with demographic trends and early polling signals. Movements in this probability would likely respond to shifts in national sentiment, economic indicators before the election, and performance of Democratic or Republican candidates in these specific states. The main catalyst shaping this probability will be campaign developments and polling movements as the election approaches, with particular sensitivity to any major national events affecting voter preferences.
- ›Iowa and Ohio have voted Republican in the last two presidential cycles (2016, 2020), establishing a baseline expectation favoring GOP performance
- ›The 35% Democratic outcome is split across multiple contracts, with 'no wins' (Republican sweep) and a single-state Democratic win tied as co-leaders, indicating market uncertainty about which specific outcome dominates
- ›Kalshi contract volume is relatively modest ($264–$332 in 24h volume per top contracts), suggesting limited price discovery and potential for shifts as market participation increases
- ›The number of possible outcomes (9 separate contracts) spreads probability mass thinly, with most individual scenarios trading at or near 3¢, reflecting low confidence in any single Democratic path through these states

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.
