Frequently Asked Questions

You can trade on game winners (moneyline), spreads, totals (over/under), and other markets across all of their upcoming games. Each market is priced as an implied probability — for example, a price of 65¢ means traders collectively believe there is a 65% chance of that outcome.

Based on their recent games, Houston Astros has a 37% win rate with a record of 11-19. You can view their full game-by-game results on this page, including scores, opponents, and context. Recent form is one of the strongest factors influencing market odds — a team on a winning streak will typically see higher implied probabilities, while a losing run often shifts odds against them.
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. Spread markets resolve based on the final margin relative to the posted line. Totals (over/under) resolve based on the combined final score. You can check the Rules on any individual market page to see the exact resolution criteria, including how postponements or cancellations are handled.
Polymarket odds are set by real traders putting real money behind their positions, which tends to produce well-calibrated probabilities.
