Analysis
The Yes side is pricing in only a 24% probability of the series extending beyond six games, implying a heavily favored sweep or 4-1 result, which seems conservative given that Philadelphia-Boston matchups historically tend to be competitive. The extreme 3773.5% implied yield on Yes reflects severe illiquidity with just $41 in 24-hour volume and $31 open interest, making the 14¢ spread unreliable for actual execution. With 31 days to expiry and recent upward price movement from 20¢ to 24¢, this market lacks sufficient depth to draw meaningful conclusions about true probability.
Resolution rules
If above 5.5 games are played in the Philadelphia vs Boston 1st Round series in the 2026 Pro Basketball playoffs, then the market resolves to Yes.
