Tip-off for the 2026-27 season is just weeks away, and rosters are already set. For American fans who’ve gotten used to checking Polymarket alongside box scores, the title market has quietly become one of the sharpest previews of the year, pricing contenders in real time as money moves rather than waiting for a sportsbook to post a number.
Two teams have separated from the field early, with a pair of challengers close enough behind to matter. Here’s how the race looks as the market sees it right now.
The Co-Favorites: Spurs and Thunder Running Neck and Neck
San Antonio sits on top at 23%, the shortest price on the board. The Spurs were everyone’s pick last spring too, grinding past Oklahoma City in a seven-game Western Conference slugfest before a red-hot Knicks team swept past them in five Finals games. That loss hasn’t dented the market’s confidence. Victor Wembanyama, Stephon Castle and Dylan Harper are all still climbing, and traders are pricing San Antonio as a team whose title window is opening rather than closing.
Oklahoma City isn’t far off at 19%, still the reigning 2025 champions and still built around Shai Gilgeous-Alexander, who added a second MVP to his résumé last season. The gap between these two has narrowed and widened a few points either way since August, tight enough that anyone opening a new position with a Polymarket referral code is stepping into a genuine coin flip rather than a one-sided bet.
The Pursuers: Knicks Defend, Sixers Swing Big
New York sits at 13%, a number that looks almost disrespectful for a team that just won it all. That’s the market pricing in the usual championship hangover: back-to-back deep playoff runs are brutal, and traders have historically been skeptical of repeat winners. Still, writing off Jalen Brunson and a defense built for playoff basketball would be premature, and 13% looks like value if last year’s grit carries over.
Philadelphia rounds out the group at 11% off the back of an offseason nobody saw coming. Signing both LeBron James and Jaylen Brown turned a seventh-seed roster that upset Boston in round one into one of the most talked-about teams in the league. Whether that translates into real contention is unproven, but the Sixers are priced like a team the market isn’t ready to dismiss.
With a month of basketball still to shake things out, these four prices are the clearest read on where the smart money sits today.
