Frequently asked questions

On Kalshi, the first inning run market dashboard tracks real-time odds and trading activity for whether Houston or Detroit will score in the opening inning of their matchup. The interface displays the current probability for each outcome, historical price movements, and 24-hour volume data. Traders use this dashboard to monitor shifting sentiment as game time approaches and to execute positions based on team lineups, weather, and pitcher matchups. The platform aggregates all buy and sell orders into a live price that reflects the collective prediction of market participants.

Prediction market odds and sportsbook odds often diverge because they serve different purposes and audiences. Sportsbooks set lines to balance action and manage risk, while prediction markets reflect the true belief of traders risking real money on outcomes. This market's odds may move faster or slower than traditional sportsbooks depending on which venue receives new information first. Comparing the two can reveal value: if this market prices Houston higher than a sportsbook does, it may signal informed traders expect stronger offensive performance in the first inning.

On Kalshi, this market is priced through a continuous order-book mechanism where traders submit buy and sell orders at their chosen probability levels. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The current odds reflect the spread between the highest bid and lowest ask, with the midpoint representing the consensus probability. As new information emerges—such as lineup announcements or injury updates—traders adjust their orders, causing the price to shift. Liquidity and order flow determine how quickly prices move and how tight the bid-ask spread remains.

This market resolves around Jun 27, 2026, once the first inning of the Houston versus Detroit game concludes. The outcome is determined by whether either team scores at least one run during that inning. Resolution is verified against credible public sources such as official MLB records and major sports data providers. Traders holding positions will see their contracts settle automatically once the result is confirmed and the market is officially closed.

Several catalysts can shift odds before the game begins. Lineup announcements, particularly the identity of each team's starting pitcher, carry significant weight since pitcher quality directly impacts early-inning scoring probability. Weather conditions—wind speed and direction at the stadium—affect ball carry and can favor or hinder offensive production. Injury reports, recent team form, and bullpen availability also influence trader sentiment. As game time approaches, any late-breaking news about player availability or weather changes will likely trigger sharp price movements in this market.
