Traders assign an 80.5% probability to “No” because current polling averages and forecasts for the November 3, 2026 midterms show no federal or statewide race projected to finish within 0.01 percentage points. Multiple Senate contests, including Iowa, Alaska, Maine, and Texas, sit near toss-up status with expected margins of 0.2 to 3 points, while competitive House districts and governor races display similar spreads. Large electorates in these contests make margins narrower than one vote in 10,000 statistically uncommon absent extraordinary turnout or counting anomalies. Historical data on U.S. elections confirms such precision is rare, and no late-October developments have altered projections toward that threshold. The market consensus therefore reflects the low base rate for an outcome this tight across the full slate of races.
