With NBA playoffs tipping off April 18, trader consensus on Polymarket prices the Boston Celtics at 38% implied probability to claim the Eastern Conference title, ahead of the No. 1 seed Detroit Pistons despite their league-best 60-22 record and home-court advantage through the postseason. Boston's No. 2 seed (56-26), championship pedigree, deep roster led by Jayson Tatum and Jaylen Brown, and cushy first-round path against the No. 7 76ers fuel their edge, especially after a late-season surge locking the spot. Cleveland Cavaliers and Pistons share 20.5%, buoyed by the Cavs' No. 4 seed versus Toronto Raptors and Detroit's Cade Cunningham-fueled dominance; New York Knicks (14.5%) hold as No. 3 hosts to Atlanta Hawks amid balanced top-four depth, with no major injury disruptions reported in official updates.
