Analysis
The Boston Celtics' Eastern Conference title odds are priced at 40¢ with a notably asymmetric implied yield structure—71% for Yes positions versus 29% for No—suggesting the market may be undervaluing the downside risk or overcompensating Yes holders for duration risk across the 805-day window. With $1.1M in open interest but only $71k in 24-hour volume, liquidity is moderate relative to the position size, and the 158% realized volatility paired with a 1.82 vol ratio indicates significant price swings despite the tight 1¢ spread. The market has drifted upward 5¢ over seven days in a neutral regime with low information arrival (0.3/h), suggesting the recent move reflects positioning rather than breaking news about the team's championship prospects.
Resolution rules
