A Baseball prediction market lets traders buy and sell shares in real-world Baseball outcomes for matchups like Texas Rangers vs. New York Yankees and Cincinnati Reds vs. Chicago Cubs. Each share is priced between 0¢ and 100¢, and the price reflects the market's implied probability that the outcome occurs.

Polymarket uses probability-based pricing rather than traditional moneyline or spread odds. A Baseball contract trading at 1¢ implies the market believes there is a 1% chance of that outcome. Prices update continuously as traders incorporate new information — injuries, weather, sportsbook movement, and in-play developments.

The most-traded Baseball markets at the moment include Texas Rangers vs. New York Yankees, Cincinnati Reds vs. Chicago Cubs, and Minnesota Twins vs. Washington Nationals. Trading volume reflects how much real money is flowing through each market and is a useful signal of where consensus is forming.

New Baseball markets are typically listed ahead of major fixtures, tournaments, and seasons. Markets are added as schedules are finalized and resolved once outcomes are official.

There are 125 live Baseball prediction markets, including ones for MLB and KBO, on Polymarket.

Polymarket Baseball prices reflect the consensus of traders putting real money at risk on Baseball outcomes — what research often calls the "wisdom of crowds" with skin in the game.

On Polymarket, Baseball predictions aren't tips, picks, or guarantees — they're the live, market-driven view of how likely each Baseball outcome is. Baseball odds are shown as prices between 0¢ and 100¢, and that price is the implied probability of the outcome. So a Baseball prediction is the question being asked ("who wins?"), and the Baseball odds are the real-time, real-money answer the market is giving.
