The Boston Celtics carry a road win streak into Toronto, and AccuScore's simulation makes them the clear favorite to keep it going: a 67.8% win probability in tonight's matchup against the Toronto Raptors.
That's consistent with how dominant Boston's season has looked through its 8-2 start. AccuScore's full-season simulation projects a 58.4-23.6 record, translating to a 97.1% playoff probability — among the strongest marks in the league.
But there's a wrinkle for fans checking where Boston stands among the NBA's elite. On the Market Index, which rates teams purely off betting prices for Week 3 of the 2026–27 season, the Celtics sit at No. 4, with a rating of +10.69 pct. That's actually down from a previous rank of No. 2. In other words: Boston keeps winning, and AccuScore's playoff math keeps loving them, but the market has cooled slightly on exactly how good this team is relative to the rest of the league.
It's a reminder that a win-loss record and a betting-market rating answer different questions. The 8-2 start and 97.1% playoff odds reflect how often Boston is projected to beat its schedule. The Market Index rank reflects strength relative to other contenders, and right now two teams have passed the Celtics there even as Boston's own number ticked up slightly.
For tonight specifically, the Raptors enter 5-5, and AccuScore still likes Boston by a wide margin — 67.8% win probability is a healthy favorite's number, not a lock. If Boston wins, the streak continues and the season projection likely holds near its current levels. If Toronto pulls the upset, it won't move the 97.1% playoff number much on its own, given how far ahead of the field Boston already is in simulations run across the full schedule.
The headline number for fans tracking Boston's night is simple: 67.8% to win, part of a season already pointing toward a 97.1% playoff finish — even with the Market Index suggesting the gap at the very top is tightening.
