All-NBA forward Jalen Williams and the big-spending Oklahoma City Thunder are finalizing a five-year supermax contract extension with a value that could inflate to $287 million.

ESPN reported Williams’ deal was agreed to on Thursday to cap a whirlwind week for the NBA champions.

Williams is the third player on the Thunder championship roster to go from the NBA Finals victory parade to the quarter-billion dollar club in the past month.

NBA MVP Shai Gilgeous-Alexander officially signed a four-year, $285 million deal on Tuesday, the same day the franchise agreed to an extension with 2022 No. 2 overall pick Chet Holmgren (five years, $250 million).

With Williams’ deal set for ink, owner Clay Bennett is on the hook at a total of $822 million for Oklahoma City’s Big Three.

Selected 10 picks after Holmgren in the same 2022 draft, Williams had a breakout season in 2024-25. He was named to the All-Star team, was named All-NBA and a member of the NBA’s All-Defensive Team while teaming with Gilgeous-Alexander to carry Oklahoma City to the franchise’s first Larry O’Brien Trophy last month.

Williams, 24, averaged 23.6 points per game in the NBA Finals as the Thunder won their first league championship. He averaged 21.4 points, 5.5 rebounds and 4.8 assists in the playoffs, when he gutted through a torn tendon in his right wrist that required surgery.
