Analysis
The 35-cent price reflects a 35% implied probability for a 4-1 San Antonio sweep, which is reasonable given that first-round series rarely end in 4-1 sweeps (historically occurring in roughly 10-15% of matchups). The extraordinarily high implied yield of 2,641.9% on the Yes side signals extreme illiquidity and suggests this is a niche outcome with minimal trading activity ($3,272.54 in 24h volume), making the price potentially unreliable for serious position-taking. With 29 days until resolution and a Cliff Risk Index of 2, the market will likely see significant repricing once the series begins and actual competitive information emerges.
Resolution rules
If the series score is San Antonio wins 4-1 in the Portland vs San Antonio 1st Round series in the 2026 Pro Basketball playoffs, then the market resolves to Yes.
