Event Horizon IQ

The Midterm Board

Every live EHIQ election call, priced against the named venue and ranked by how far our probability sits from the market price. Each call is dated at open and linked so you can see the market for yourself. Election day is November 3, 2026, 44 days out.

Prices come from the same refresh that feeds our weekly digest. A price older than 24 hours is withheld rather than shown stale. The full cross-category board lives on /divergence, and every resolved call is graded on /record.
