You can trade on game winners (moneyline), spreads, totals (over/under), and other markets across all of their upcoming games.

Each MLB market on Polymarket is structured as a yes/no question — for example, "Will Houston Astros win?" You buy shares in "Yes" or "No" at the current market price, which reflects the crowd-sourced implied probability. If your side is correct when the game concludes, your shares pay out $1 each. If incorrect, they pay $0. You can also sell your shares at any time before the game ends to lock in a profit or cut a loss. Prices update in real-time as traders react to news like injury reports, lineup changes, and other developments.

All Houston Astros markets resolve based on official game results, including overtime or extra periods where applicable. Moneyline markets resolve based on the final result of the game.

You can check the Rules on any individual market page to see the exact resolution criteria, including how postponements or cancellations are handled.
