This market tracks which team will win the professional baseball game between the Miami Marlins and Houston Astros. On Kalshi, the current probability of Miami winning is 98.0%, with Houston at 3.0%. The resolution source is based on the game's result as originally scheduled. Watch for the game on July 22, 2026 at 8:10 PM EDT, as this is the event that will determine the market outcome.
The event consists of two mutually exclusive outcomes corresponding to each team's victory in the Miami vs Houston professional baseball game originally scheduled for July 22, 2026 at 8:10 PM EDT. If the game is postponed or delayed, markets remain open and close after the rescheduled game concludes within two days.

Prediction market odds and sportsbook odds often diverge because they serve different purposes. Sportsbooks set lines to balance action and lock in profit margins, while prediction markets reflect pure trader belief without a built-in margin. This market aggregates the views of many independent traders with real money at stake, which can reveal insights sportsbooks miss. However, sportsbooks may move faster on breaking news or injury reports. Comparing the two can highlight where the crowd sees value that traditional oddsmakers have overlooked.
On Kalshi, this market is priced through a continuous order-book mechanism where traders submit bids and asks for shares representing each possible outcome. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price of each share reflects the probability traders assign to that outcome, ranging from near-zero to near-100. As new trades execute, prices update instantly. You can enter limit or market orders to buy or sell shares at your preferred price, and the spread between bid and ask represents the current disagreement among traders on the true probability.
This market resolves around Jul 23, 2026, once the matchup concludes and the result is verifiable from credible public reporting. The outcome will be confirmed based on the final score and official game records. Until that point, prices will fluctuate as traders react to team news, injury updates, betting trends, and other signals that may shift expectations. After resolution, all shares will be settled according to the confirmed result, and traders' profits or losses will be finalized.
Key player injuries, roster changes, or unexpected absences can significantly shift odds as traders reassess team strength. Recent form, head-to-head records, and momentum heading into the game often trigger repricing. Weather conditions, travel schedules, and rest advantages may also influence trading. Major news—such as coaching decisions or lineup announcements—typically sparks sharp moves. Additionally, early betting action from sharp bettors and line movement at sportsbooks can signal where informed money is flowing, prompting traders to adjust their positions before the game begins.
