Analysis

11d ago

This market shows extreme mispricing with a 3,696% implied yield on the Yes side, suggesting the 25¢ price significantly undervalues the probability of 3+ first-round upsets. The sharp 10-cent rally over 7 days (from 15¢ to 25¢) combined with modest $869 daily volume and a wide 7¢ spread indicates thin liquidity and potential for rapid repricing as the May 16 expiry approaches in 30 days. The neutral regime and moderate Cliff Risk Index of 3 suggest this is a genuine probability misjudgment rather than a liquidity-driven anomaly, making it potentially attractive for contrarian traders with conviction that upset rates will exceed market expectations.

Resolution rules

If the teams in the Pro Basketball playoffs record at least 3 series upsets in the 1st Round of the 2026 Pro Basketball Playoffs, then the market resolves to Yes.
