Analysis
The Yes position trades at an extreme 2496% implied yield, suggesting severe underpricing relative to the ~40% historical probability of first-round series extending beyond six games, though the modest $102.78 daily volume indicates thin liquidity that may explain the mispricing. The market has drifted upward 14% over seven days (28¢ to 32¢) despite the unfavorable odds, and with 31 days to expiry, there's meaningful time for repricing if either team's injury status or playoff seeding shifts market expectations. The 5¢ spread and low Cliff Risk Index (2) suggest this is a relatively stable contract, but the extreme yield differential warrants caution about whether the pricing reflects genuine market consensus or simply insufficient capital deployment.
Resolution rules
If above 5.5 games are played in the Portland vs San Antonio 1st Round series in the 2026 Pro Basketball playoffs, then the market resolves to Yes.
