Boston is the marginal 52.5c moneyline favorite over the New York Mets (49.5c) in a near pick-em Red Sox vs Mets line, tight despite the Red Sox sitting 16 games clear of the Mets in the standings (45-48 to 40-56). Kalshi (53c) and Polymarket (52c) agree within a cent on Boston, so there is no cross-platform edge to work. First pitch is 1:40 PM ET at Citi Field on Sunday, July 12, 2026, and the live board above carries the current prices across both books.
Boston opens as a marginal favorite on the road in Queens, priced at 52.5c on the moneyline against a New York Mets team it outpaces by 16 games in the standings. The near pick-em line is a home-field story: the Red Sox are the better club at 45-48, but the Mets get enough of a bump playing at Citi Field to hold the number close. The live board above tracks the current Kalshi and Polymarket prices; first pitch is 1:40 PM ET on Sunday, July 12, 2026.
Boston is the 52.5c side (53c on Kalshi, 52c on Polymarket), with the Mets at 49.5c (50c Kalshi, 49c Polymarket). The two books agree within a single cent on each team, so there is no cross-platform arbitrage to work here, and the market is efficient and tight. That pricing is notable because the Red Sox (45-48) sit 16 games ahead of the Mets (40-56) and carry the road-team profile the record suggests, going 28-21 away from Fenway against a 17-27 mark at home. New York, by contrast, is 21-27 at Citi Field and 19-29 on the road.
The probable pitchers reinforce Boston's edge. Payton Tolle (5-6, 3.14 ERA) takes the ball for the Red Sox against New York's Zach Thornton (0-1, 4.35 ERA), a run-plus gap in ERA that argues Boston should sit higher than a coin flip. Home-field advantage is doing the work that keeps the Mets near even money. On the bats, Juan Soto anchors the Mets lineup at .294 with 21 home runs and 51 RBIs, while Boston leans on Jarren Duran (13 home runs, 44 RBIs) and Ceddanne Rafaela (.282).
The run line reads the same way the moneyline does. Boston to win by more than 1.5 runs trades at 40c, ahead of the Mets at 33c to do the same, a spread that tracks Boston's small edge without conviction. The total sits around 8.5 runs: Over 8.5 is priced at 49c, with Over 7.5 at 57c and Over 9.5 at 39c, so the market is pricing a game in the mid-to-high single digits. Tolle's 3.14 ERA is the main reason the total is not higher despite Soto and a lineup that can score.
Line movement has been modest. Boston opened at 50c on Polymarket, a true coin flip, and firmed to 52c over the evening, a 2c drift toward the Red Sox that lines up with the pitching edge. Kalshi has held Boston in the low 50s across the same window, so both books are moving in the same direction.
