Polymarket YES price as of 2026-08-30T13:50:53.366927Z for: Boston Red Sox vs. New York Yankees
The sportsbook consensus gives the home team (Yankees) a 49.1% win probability, implying Boston (away) has ~50.9%. Records show Yankees 77-59 (home) vs Red Sox 74-62 (away). The home team advantage slightly favors Yankees. Starting pitchers: Will Warren (Yankees) vs Ranger Suarez (Red Sox). The odds are essentially even. Given near-equal records, roughly even pitching matchup, and sportsbook implying slight Red Sox edge but home field favoring Yankees, I'll estimate Boston's win probability at approximately 0.49.
The sportsbook consensus implies roughly a 49.1% chance for the Yankees at home, so about 50.9% for Boston before adjusting for vig. However, the listed starters favor Boston less than a generic coin flip: Ranger Suarez is typically a stronger, more established option than Will Warren, while New York also has the slightly better record and home field. Balancing those factors against likely modest overround in the odds, I put Boston just under even money. I assign a small extra haircut for postponement/tie resolution risk being effectively unfavorable.
