If a tie still persists, this market will resolve in favor of the pitcher that records more strikeouts during the 2026 MLB regular season. If a tie still persists, then this market will resolve in favor of the pitcher that walked fewer batters during the 2026 MLB regular season.

The resolution source for this market will be official information from MLB; however, a consensus of credible reporting may also be used.

How trading works

Polymarket uses a central limit order book (CLOB) model — you can buy or sell shares of any outcome at the current market price, or place limit orders. Prices represent implied probability: a $0.65 contract means the market prices a 65% chance of that outcome.
