Summary
- Isaiah Hartenstein signed a new deal through the 2028-29 season.
- The contract is worth a guaranteed $134 million over five years.
- This ensures key championship players are under contract for at least three years.

The Oklahoma City Thunder have finalized a significant contract extension for Isaiah Hartenstein, ensuring his presence through the 2028-29 season. This new agreement is reportedly a three-year deal worth $75 million in new money, bringing his total guaranteed earnings with the franchise to $134 million over a five-year span. The contract also includes a 15% trade kicker and a mutual option for 2028.
Hartenstein's long-term commitment solidifies Oklahoma City's championship aspirations, keeping key players like Shai Gilgeous-Alexander, Jalen Williams, Chet Holmgren, and Alex Caruso under contract for at least the next three years. Despite a high payroll, the Thunder are prioritizing continuity after their championship run.
While Hartenstein averaged 9.2 points and 3.5 assists last season in 47 games, his previous performance, including 11.2 points per game during their title-winning season, underscores his value. His contract, which was agreed upon before the 2026 season, has generated mixed reactions, with some fans questioning roster construction and potential departures of other players like Lu Dort.
