This event tracks combined run production during only the first five innings of the Houston vs Kansas City game on June 13, 2026. Bettors predict whether the teams will collectively score above various thresholds in the early portion of the game. If the game is postponed or delayed, the market remains open and resolves after the rescheduled game completes within two days.
Resolution is based on the combined run total scored by Houston and Kansas City during the first five innings of the game originally scheduled for June 13, 2026 at 7:10 PM EDT. Each market corresponds to a specific run threshold (0.5, 1.5, 2.5, 3.5, 4.5, 5.5, or 6.5 runs). A market resolves to Yes if the combined first-five-inning total exceeds its designated threshold; otherwise it resolves to No. If the game is postponed or delayed, the market remains open and closes after the rescheduled game has finished, provided the rescheduled game occurs within two days of the original date. The official box score as recorded by Major League Baseball determines the first-five-inning run totals.
Prediction market odds and sportsbook odds often diverge because they reflect different participant bases and incentive structures. Sportsbooks set lines to balance action and lock in profit margins, while prediction markets like this one are driven by trader consensus and real-money risk. Sportsbooks may adjust lines faster in response to sharp action, whereas prediction markets aggregate dispersed information over time. For first-inning totals, sportsbook odds typically tighten around game time, whereas prediction markets can remain more volatile if new information—such as late lineup announcements or weather updates—emerges. Comparing the two can reveal where public perception and informed traders diverge.
On Kalshi, this market is priced through a continuous order-book mechanism where traders submit bids and offers on shares representing outcomes. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price of each outcome reflects the marginal trade—the last executed transaction—and moves as new orders flow in. Traders can buy or sell fractional shares, and the platform matches orders in real time. Prices typically converge toward fair value as more participants trade, especially as the game approaches. The bid-ask spread widens or tightens depending on order flow and uncertainty, so watching the order book can signal whether traders expect a shift in the total.
This market resolves around Jun 14, 2026, once the first five innings of the Houston-Kansas City game are complete and the combined run total is verified against credible public sources. The outcome is determined by the official box score recorded by Major League Baseball, which tallies all runs scored by both teams through the end of the fifth inning. No runs scored in extra innings or after the fifth inning count toward this market. Resolution occurs shortly after the game data is finalized and confirmed by the platform.
Several catalysts can shift prices before the game begins and during the first five innings. Lineup announcements, injuries to key batters or pitchers, and weather conditions—wind direction and speed affect ball carry—often trigger repricing. Recent offensive trends, bullpen availability, and head-to-head matchup history also influence trader positioning. Once play starts, early runs, pitcher effectiveness, and defensive plays drive inning-by-inning adjustments. Late-breaking news such as a starting pitcher change or a player entering health and safety protocols can cause sharp moves. Traders monitoring these signals in real time often capitalize on price dislocations before the broader market reprices.
