Analysis

2d ago

This Wisconsin House seat market shows extreme illiquidity with zero 24-hour volume despite nearly $1M open interest, suggesting the $965k position may be stale or concentrated. The 28¢ price implies a heavily Democratic-favored district, yet the 498% implied yield on Republican victory and extraordinary 2191% realized volatility signal either significant model uncertainty or potential mispricing given the 198-day timeframe. The wide 35¢ spread and 8.92 volatility ratio warrant caution—this appears to be a thin, potentially illiquid market where large moves could occur on minimal news flow (4.3 info arrivals per hour).
