AI Insights:
03.05 10:35 UpdatedFair Value Reasoning:
Based on the ~2.1M votes cast in the March 3, 2026 GOP primary, and historical data showing Texas runoffs typically see a 30-50% turnout drop (e.g., ~50% drop in 2022 AG runoff, ~20% in 2012 Senate runoff). Given the high-profile 'Cornyn vs Paxton' civil war (similar to Cruz vs Dewhurst 2012), retention should be relatively strong, placing the most likely outcome in the 1.0M-1.5M range (50-70% of primary). The market significantly overprices high-turnout options (>1.8M), ignoring standard runoff attrition.

Divergence
Severe divergence. Polymarket pricing implies a high probability of 1.8-2.1M turnout (matching primary turnout), which contradicts Texas historical data showing significant drop-offs in runoffs. The market completely ignores the standard attrition pattern, diverging sharply from historical norms and expert consensus.
