Who will win the 2026 Iowa Senate election
Analysis
The 58% probability reflects market expectations that Republican Ashley Hinson will win Iowa's 2026 Senate seat. This represents a substantial but not overwhelming advantage over Democrat Zach Wahls at 14% and independent Josh Turek at 26%. The current pricing reflects Hinson's incumbent status and recent electoral performance in Iowa, though the substantial runner-up probability suggests meaningful uncertainty about voter preferences heading into the general election. Key factors affecting this outcome include national political environment shifts, candidate fundraising and campaign performance, and demographic voting patterns in Iowa. The general election on November 3, 2026, will ultimately resolve the race, though primary outcomes and debate performances may significantly move probabilities in the months beforehand.

2026 Midterms: Democrats 85% to Flip House, Senate a Toss-Up

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.
