The Chicago White Sox open as the home favorite at 56.5c (57c on Kalshi, 56c on Polymarket) against the Houston Astros at 44c in the Astros vs White Sox market for July 24, 2026. Chicago sits 54-47 and 31-17 at Rate Field, while Houston arrives 50-54 and 24-27 on the road. First pitch is scheduled for 7:40 PM ET.
Astros vs White Sox Market Context
The White Sox at 57c imply about a 57% chance to win at home, and the records support the price. Chicago is seven games over .500 at 54-47 with a 31-17 home mark (.646), one of the stronger home splits in the league, and the Chicago White Sox have leaned on that home edge all season. The Houston Astros are four games under .500 at 50-54 and 24-27 away from home, which is why the market lists them as the 44c road underdog rather than the favored side their franchise name usually commands.
The board is tightly agreed across platforms. The White Sox moneyline is 57c on Kalshi and 56c on Polymarket, a 1c gap, and the Astros sit at 44c on both books. That convergence means neither platform offers a clear pricing edge on the moneyline for July 24, 2026. The moneyline has also held into game day: the White Sox opened at 58c on Kalshi and sit at 57c, a 1c drift, while the Astros have stayed at 44c through the session. Steady pricing plus the heavier Kalshi volume on the White Sox contract points to conviction on the home side rather than a market still searching for a number.
Astros vs White Sox Pitching and Run Line
Chicago is projected to start Davis Martin against Houston's Spencer Arrighetti, and the strikeout props frame the matchup. Arrighetti's over 4.5 strikeouts sits at 62.5c and his over 3.5 at 67.5c, pricing him for roughly five punchouts, while Martin's over 3.5 is 66c and his over 4.5 drops to 46c, a shorter leash from the market. Houston's Yordan Alvarez, who leads the Astros in average (.328), home runs (34), and RBI (77), is priced at 26c to go deep on a home run over 0.5 and 72c to record at least one hit. Chicago counters with Colson Montgomery, the team home run leader at 24, and Miguel Vargas, who paces the club with 61 RBI.
On the run line, the White Sox -1.5 trades near 39.5c and the Astros -1.5 near 32.5c, so the market gives Chicago about a 40% chance to win by two or more and Houston roughly 33%. The total sits at 8.5 runs and is priced as close to a coin flip (52c to the over on both books), with over 7.5 runs at 57.5c and over 9.5 at 40.5c. The first-inning run market is 51.5c, another near-even read that tracks two starters the board expects to work into the middle innings.
