Analysis
This market shows extreme illiquidity with only $556.88 open interest and zero 24-hour volume, making the 53¢ price potentially unreliable for serious trading. The massive spread (43¢) and extraordinarily high implied yields (188.5% for Yes, 239.7% for No) reflect the thin liquidity rather than genuine market conviction about the Mariners' 2026 prospects. With 172 days to expiration and a neutral regime, this market lacks sufficient trading activity to serve as a meaningful probability signal.
Resolution rules
This market will resolve to "O 88.5" if the Seattle Mariners win more than 88.5 games during the 2026 MLB Regular Season. If at any point it becomes statistically impossible for the Seattle Mariners to record more than 88.5 wins per the rules of the MLB, the corresponding market will resolve to "U 88.5". If the MLB Regular Season is cancelled, partially completed, or postponed after November 30, 2026, 11:59 PM ET, this market will resolve to "50-50". The resolution source will be official information from Major League Baseball (https://www.mlb.com/standings/); however a consensus of credible reporting may also be used.
