Wisconsin Governor Democratic Primary Margin of Victory (0.2% Brackets)

Platform comparison

Market context

Wisconsin's Democratic primary for governor takes place on 11 August 2026, with the margin between the top two finishers determining settlement. The market currently shows 0% implied probability across all brackets, suggesting either extreme uncertainty about the field or insufficient liquidity to establish meaningful odds. This stands in sharp contrast to general-election forecasting, where Wisconsin remains a perennial swing state with robust trading activity. The absence of consensus pricing here reflects the early stage of the primary cycle and the lack of declared candidates or polling data specific to the Democratic side.

Historical Wisconsin Democratic primaries offer limited precedent for predicting margin distributions. The 2018 gubernatorial primary saw Tony Evers defeat Kelda Roys by roughly 45 percentage points in a three-candidate field, though that reflected a frontrunner with substantial name recognition. Earlier primaries in the state have produced closer contests, particularly when multiple credible candidates competed. The current 0% reading suggests traders are awaiting concrete candidate announcements and initial polling before committing capital to any margin bracket.

Key catalysts include formal candidate declarations, which typically accelerate in spring 2026, and any early polling released by Wisconsin-based news outlets or Democratic organisations. Endorsements from sitting officials and organised labour will shape momentum in the months preceding August. The settlement window closes immediately after polls close on 11 August, leaving no time for provisional ballot counting disputes to influence resolution. Traders should monitor whether the Democratic field remains contested or consolidates around fewer candidates, as this directly affects the probability distribution across margin brackets.
