Decoding the Market: How to Trade the Astros vs. Mariners

For those new to Polymarket, it’s important to understand that this is a peer-to-peer prediction market, not a standard betting line. Here, prices represent the implied probability of an outcome.

For example, if a side is trading at 54¢, the market believes there is a 54% chance of that outcome occurring. The payout is based on the difference between your purchase price and the final outcome (which settles at $1.00).
