Center Isaiah Hartenstein is reportedly expected to re-sign with the Oklahoma City Thunder on a three-year contract, ESPN's Shams Charania reports.
The value of the deal will be $75 million, according to Charania. Hartenstein previously had a $28.5 million team option for the 2026-27 season, but the Thunder declined that option in favor of the new three-year agreement with an additional $46.5 million.
Additionally, the contract reportedly includes a 15% trade kicker and a mutual option for the final year of the deal that allows both sides to rework the terms for the 2028-29 season.
Hartenstein, 28, averaged 9.2 points and 9.4 rebounds in his second season with Oklahoma City after signing a three-year, $87 million free agent contract that included the aforementioned $28.5 million team option.
In two seasons with the Thunder, Hartenstein has averaged 10.3 points and 10.1 rebounds per game, the best numbers of his career. He's also been a reliable postseason presence, playing in all 38 of Oklahoma City's playoff games with 35 starts. In the playoffs, he's averaged 9.1 points, 8.3 rebounds and 2.6 assists.
During his eight NBA seasons, the 7-footer has also played for Houston Rockets, Denver Nuggets, Cleveland Cavaliers and New York Knicks.
Hartenstein will be under contract with the Thunder for a total of five years and $134 million. That brings down his average annual salary slightly from the $28.5 million he earned with his first contract to $26.8 million per year. That still ranks him among the top 15 NBA centers in average annual salary.
In Hartenstein's two seasons with Oklahoma City, the team has a combined 132-32 regular-season record, advancing to two Western Conference finals and winning the 2024-25 NBA championship.
On a team full of scorers including two-time NBA MVP Shai Gilgeous-Alexander, Jalen Williams and Chet Holmgren, in addition to Ajay Mitchell and Jared McCain, Hartenstein is an invaluable role player in the frontcourt and the Thunder demonstrated that by signing him to a new contract.
