Fair Value Reasoning:

Based on historical data, the probability of a No. 15 seed beating a No. 2 seed is approximately 7% per game (historical record ~11-160). While upsets occurred consecutively from 2021-2023, the trend cooled with no upsets in 2024 or 2025. Calculating the probability of at least one win in four matchups (1 - 0.93^4 ≈ 25%) and referencing competitor market pricing (e.g., Kalshi at 22 cents), the fair value lies between 22-25 cents. The current market price of 50 cents is significantly inflated due to illiquidity.

Divergence

Significant divergence. Mainstream predictive models and historical stats suggest a win probability of around 25% for a 15-seed, with external prediction markets pricing it at ~22%. This market's 50% pricing represents a massive premium, likely driven by market inefficiency (lack of market makers) rather than informational disagreement.
