This event group covers the MLS regular season match between St. Louis City SC and Seattle Sounders FC scheduled for March 7, 2026. Markets are offered on Kalshi and Polymarket, with Kalshi covering all three outcomes (Seattle win, St. Louis win, or draw) and Polymarket offering three separate binary markets (Seattle win, St. Louis win, draw). Resolution is based on the result after 90 minutes of regular play plus stoppage time, excluding extra time and penalties.
Kalshi's market structure contains a logical contradiction where all three mutually exclusive outcomes are defined to resolve to Yes, making the market fundamentally unresolvable. Polymarket's three separate binary markets are logically consistent and mutually exclusive.
Hero Tip:
Kalshi's market as written is unresolvable due to internal contradiction. Polymarket's structure is the only logically sound framework. Avoid Kalshi until clarification. Use Polymarket as the authoritative resolution source.
Critical Divergence Points:
Kalshi: Defines three outcomes where Seattle win resolves Yes, St. Louis win resolves Yes, and Draw resolves Yes. This is logically impossible since exactly one outcome must occur. Quote: 'If Seattle wins...then the market resolves to Yes. If Saint Louis wins...then the market resolves to Yes. If Tie wins...then the market resolves to Yes.'
Polymarket: Offers three separate binary markets with mutually exclusive logic: Seattle Win (Yes if Seattle wins, No otherwise), St. Louis Win (Yes if St. Louis wins, No otherwise), Draw (Yes if draw, No otherwise). Cancellation rule: if game canceled with no makeup, Draw resolves Yes and Win markets resolve No. Quote: 'If Seattle Sounders FC wins, this market will resolve to Yes. Otherwise, this market will resolve to No.'
