Thunder to re-sign center Hartenstein on three-year, $75 million deal

Isaiah Hartenstein intends to sign a new three-year, $75 million contract to remain with the Oklahoma City Thunder through the 2028-29 season. The agreement was negotiated by Hartenstein's representatives at CAA Sports and includes a maximum 15 percent trade kicker along with a mutual option that allows both sides to rework the contract before the final season.

Contract details The new deal brings Hartenstein's total guaranteed earnings with the Thunder to $134 million over five years. Hartenstein, 28, joined the Thunder as a free agent in the summer of 2024 and has served as the team's starting center.

Performance and injury history In his first two regular seasons with Oklahoma City, Hartenstein averaged 10.3 points, 10.1 rebounds and 3.7 assists per game. He has appeared in all 38 of the Thunder's playoff games over the past two seasons, starting 35 of them, and posted postseason averages of 9.1 points, 8.3 rebounds and 2.6 assists.

Injuries have limited his availability. A broken left thumb kept him out at the start of the 2024-25 season, and a lingering right calf strain restricted him to 104 regular-season games across his two years with the team.
