- Isaiah Hartenstein intends to sign a three-year, $75 million contract to return to the Oklahoma City Thunder through the 2028-29 season, with reps Andrew Morrison and Aaron Mintz of CAA Sports negotiating the deal.
- The contract includes a maximum 15% trade kicker and a unique mutual option allowing both the Thunder and Hartenstein to rework the agreement again in 2028 before the final season.
- The new deal brings Hartenstein's total guaranteed earnings with the Thunder to five years and $134 million.
- Hartenstein, a 7-foot, 250-pound center who arrived in OKC as a free agent in summer 2024, was one of the finishing pieces of the Thunder's championship puzzle, filling a glaring need for physical interior presence.
- In his first two OKC seasons, Hartenstein averaged 10.3 points, 10.1 rebounds and 3.7 assists as the starting center, though a broken left thumb and a lingering right calf strain limited him to 104 regular-season games.
- Hartenstein has appeared in all 38 of the Thunder's playoff games over the past two postseasons, starting 35, with averages of 9.1 points, 8.3 rebounds and 2.6 assists in the playoffs.
Why it matters: OKC retains its starting center at roughly $25M per year average, locking in the interior anchor of a championship roster rather than letting him walk in free agency. The 2028 mutual option gives both sides an early renegotiation window — useful insurance given Hartenstein's injury history, which already cost him time in both his OKC regular seasons.
