Cleveland is the 54c favorite for game 2 at Progressive Field on September 15, 2026, and Kalshi and Polymarket post the identical number on both sides of the moneyline. The standings cut the other way: Chicago took the opener 7-3 and pushed its AL Central lead to 1.5 games, so the White Sox (77-73) can push the Guardians (76-75) further back with a second straight win in Cleveland. The board carries roughly $17.3K in lifetime volume across the two venues and settles when the game goes final.
Chicago walked into Progressive Field and took the opener 7-3, pushing the AL Central lead from a half game to 1.5. The market still sides with the home team for game 2: Cleveland is 54c on both books against 47c for the White Sox, a 54% implied chance for a club that is 36-40 at home this season. Roughly $17.3K in lifetime volume has come through the board across Kalshi and Polymarket, with about $13.5K of that sitting in the two moneyline legs. Prices in this piece are the board as observed late on September 14, 2026, and the live widget above carries the current read.
White Sox vs Guardians Market Context
The standings argument runs against the favorite. Chicago is 77-73 and .513, Cleveland is 76-75 and .503, and the 1.5-game gap is the widest this division lead has been in the stretch run. Detroit sits 6 games back at 71-79 on a five-game win streak, so taking the remaining two games here is the realistic path back to the top of the AL Central for the Guardians. Chicago carries a one-game win streak into game 2, Cleveland a one-game skid.
The splits explain part of the 54c number and complicate the rest. Cleveland is 36-40 at Progressive Field and 40-35 away from it, one of the few clubs that has been better on the road than at home. Chicago is 43-31 at home and 34-42 on the road, so this is the version of the White Sox the market prices down. Head to head, though, Chicago leads the regular-season series 7-4 across 11 completed meetings, including the 7-3 opener.
Recent form is a wash. Cleveland is 2-3 over its last five, with 5-2 and 9-2 wins at Minnesota on September 12 and September 13 bracketed by losses. The White Sox are also 2-3 over that span, dropping two of three at St. Louis before the opener win.
Cross-platform there is nothing to shop. Kalshi and Polymarket post Cleveland at 54c and Chicago at 47c, identical to the cent on both legs, and the pair sums to 101c for a 1c overround. Across every snapshot captured between 8:36 PM and 10:25 PM ET on September 14, both legs held: Cleveland never moved off 54c and Chicago never moved off 47c. The only movement observed in that window was the Chicago -2.5 run line ticking from 28c to 27c on Polymarket.
White Sox vs Guardians Pitching and Props Read
Cleveland has Foster Griffin listed as its probable starter as of September 14, a 15-5 season with a 3.65 ERA that ESPN ranks 23rd in the majors. Chicago is listed behind Davis Martin at 9-7 with a 4.05 ERA. Martin has seen this lineup already, having started the August 9 finale in Chicago.
The total is a genuine coin flip. Over 8.5 runs prices at 51c, matching the 8.5 number posted on the game, with Over 7.5 at 58c and Over 9.5 at 41c. Team totals lean fractionally toward the home side: Cleveland over 3.5 runs is 60c against 56c for Chicago over 3.5. The run line is close to symmetric, Cleveland -1.5 at 37c and Chicago -1.5 at 35c, which is the shape a 54c favorite in an 8.5-run game should produce.
The first-inning run market is the second-deepest rung on the board at about $2.8K in lifetime volume, priced 50c on Kalshi and 51c on Polymarket. It is the only non-moneyline market here with meaningful depth. The spread and total rungs each carry under $500, so treat those quotes as indicative rather than traded.
Availability matters more for the home side. Angel Martinez, Cleveland's home run leader at 15, is day-to-day with a side issue, and Rhys Hoskins is on the 10-day injured list with a back issue. Chicago is without Tommy Pham (10-day injured list, calf) but has Miguel Vargas at 31 home runs and Colson Montgomery at 84 RBI available.
When the White Sox vs Guardians Market Resolves
The moneyline resolves to the team that wins the game at Progressive Field on September 15, 2026, scheduled for 6:40 PM ET. The Kalshi ticker encodes the same 6:40 PM ET start the ESPN scoreboard lists, so the two independent sources agree on first pitch. Winning contracts pay $1 per share and the losing side settles at zero. The run line and game total settle on the final score including extra innings, and the first-five-innings rungs settle on the score after five complete innings. Every rung settles once the game goes final, and a postponement pushes settlement to the completion of the rescheduled game under each platform's rules.

- Depth is concentrated: about $13.5K of the board's $17.3K lifetime volume sits in the moneyline and $2.8K in the first-inning run market.
- Series control: Chicago leads the regular-season series 7-4 and took the September 14 opener 7-3.
