Analysis

7d ago

This market shows extreme mispricing with a staggering 9120% implied yield on the Yes side, suggesting the 13¢ price significantly undervalues Boston's probability of winning 4-3—a plausible outcome in a competitive first-round matchup. The sharp 9¢ price drop over seven days (from 3¢ to 12¢) combined with low liquidity ($527 24h volume) and high cliff risk (7/10) indicates potential manipulation or a liquidity crunch rather than fundamental repricing. With 29 days to expiry and tight 1¢ spreads, this appears to be a mispriced niche market where informed traders could exploit the Yes side's asymmetric payoff structure.

Resolution rules

If the series score is Boston wins 4-3 in the Philadelphia vs Boston 1st Round series in the 2026 Pro Basketball playoffs, then the market resolves to Yes.
