The reigning NBA champions, the Oklahoma City Thunder, have locked down another key piece for years to come. Chet Holmgren has agreed to a maximum rookie extension according to ESPN’s Shams Charania who cited Bill Duffy of WME Basketball. The extension is for five additional years fully guaranteed, keeping him under contract through the 2030-31 season.

Holmgren joins Shai Gilgeous-Alexander in signing a lucrative extension this off-season with the champs. Gilgeous-Alexander signed his extension on Tuesday, also keeping him with the Thunder through 2031.

Holmgren was the second selection in the 2022 NBA Draft, but sat out the entire 2022-23 due to a Lisfranc injury to his right foot. He also sustained a serious injury during the 2024-25 season, missing games from mid-November until early February with a pelvic fracture. He recovered to play an instrumental role in the Thunder’s championship run. He finished the season averaging 15 points and 8 rebounds per game.

Next up in importance for the Thunder is a rookie extension for Jalen Williams. Charania states that there is momentum to get such an extension done. Only the 1977 Portland Trail Blazers were a younger team that won the NBA championship, and now it appears that Oklahoma City is well on the way to locking down their best players for more than the next half-decade.
