Analysis

4d ago

Horiguchi's championship odds have tripled from 2¢ to 6¢ over seven days, yet the market shows zero 24-hour volume and an unusually wide 8¢ spread, suggesting thin liquidity despite $372k open interest. The 2216.8% implied yield on the yes side is extreme and likely reflects the low base probability rather than genuine edge—typical for long-shot binary outcomes with minimal trading activity. With 258 days to resolution and a neutral regime, this appears to be a speculative position with limited price discovery rather than an actively traded market.
