The Oklahoma City Thunder have taken a hit to their NBA championship odds after star Jalen Williams suffered a severe lower leg injury on Sunday, Oct. 25 against the Los Angeles Clippers.
Williams, an All-Star and key contributor to Oklahoma City’s 2025 championship, was taken off the court on a stretcher late in the Thunder’s 108-101 victory.
The Thunder entered the season as the favorite to win the NBA title in the betting markets, but the injury changes the pathway for Oklahoma City moving forward. Team general manager Sam Presti said both Williams and fellow starter Cason Wallace will need surgery.
Williams has a fractured fibula and a dislocated ankle on the left side, while Wallace has a labral tear in his left shoulder. Presti did not provide a timeline for either Williams' or Wallace's return.
As of 7:17 p.m. ET, Oct. 26, the Thunder’s title odds lengthened to +347 from +238 on Oct. 24, per BetFinder’s consensus. That shift dropped Oklahoma City behind the San Antonio Spurs, who became the new championship favorite at +290.
The Thunder's odds had already lengthened to +309 earlier Monday, before Presti's press conference detailing the extent of the injuries.
In implied probability – the likelihood of winning suggested by betting odds – Oklahoma City fell 7.2 percentage points from 29.6% to 22.4%. That’s the largest peak-to-trough decline of any NBA team in BetFinder data dating to July 7.
The Miami Heat have experienced the next-largest drop, falling 3.4 percentage points from their July 22 peak to their Oct. 26 low. San Antonio also fell 3.4 points between its July 8 peak and Oct. 25 low.
No other team has seen a peak-to-trough decline exceeding two percentage points.
Oklahoma City’s change came over just two days. By comparison, Miami’s decline stretched from late July into October, while San Antonio’s peak and subsequent low followed a similar trend. The timing makes the Thunder’s slide especially abrupt.
Despite the injury to Williams and Wallace, Oklahoma City still has a stacked roster, led by two-time and defending MVP Shai Gilgeous-Alexander and Chet Holmgren, who ranked second in last season’s defensive player of the year honors. Holmgren is dealing with right patellar tendinitis, however, and will miss the Thunder's game against the Phoenix Suns on Monday, Oct. 26.
And with that in mind, bettors still give the Thunder a just over one-in-five shot at the title, per implied probability.
The third-ranked team in championship odds is the LeBron James-led Philadelphia 76ers at +925. No other team has odds shorter than +1000, while the defending champions New York Knicks sit right at that line.
