Thesis
EHIQ has Nathan Turek as the favorite (~66%) to win the Iowa Democratic Senate primary, against a market (Kalshi) that has him around 35%. The two public polls of this race disagree by nearly 40 points — one favors each candidate — so a poll-based read collapses to a coin flip and carries no information. Our language-based signal favors Turek. We haircut the conviction deliberately because intra-party primaries are a lower-confidence regime for the method than general elections. Direction: a market FADE, logged before the vote.
- 1.The two public polls are ~38 points apart — one favors each candidate. A poll-aggregation read can't separate them; it lands on a coin flip with no signal.
- 2.Our language-based signal favors Turek; the market (Kalshi) favors Wahls at roughly 63-65%.
- 3.Intra-party primaries are a lower-confidence regime than general elections, so we widen the band rather than claim full signal strength — the call is haircut from a raw ~75% to ~66%.
- 4.This is a market FADE logged before the vote. Resolves on primary day, June 2, 2026.

Outcome
YES
Resolved
June 3, 2026
Turek won the Iowa Democratic Senate primary 62.6% to Wahls 37.4% (AP projected 2026-06-02, 98%+ counted). EHIQ called Turek at 65-66% against Kalshi's 35%, a +30pp market-fade that paid. The gate-derived call (TIQ + SEM after Layer-3 intra-party haircut) was direction-correct and conviction-correct. Strongest single-call market-fade hit since Brexit (59-day lead) and Biden-Hur (164-day lead). Turek now faces Rep. Ashley Hinson in the November general.
