Center Isaiah Hartenstein has reached a three-year, $75 million agreement with the Oklahoma City Thunder, according to reports published Saturday, June 27, 2026.
The new contract keeps the 7-footer in Oklahoma City through the 2028–29 NBA season. Financial terms place the average annual value at $25 million.
Hartenstein, 28, joined the Thunder during the 2025–26 campaign and averaged double figures in scoring while providing interior defense and rebounding. His performance helped Oklahoma City secure a postseason berth and prompted the front office to move quickly to retain him as free agency opened.
The agreement cannot become official until the league’s moratorium on transactions is lifted next month.
