The Oklahoma City Thunder have reached agreement with forward Jalen Williams on a five-year rookie maximum extension that could be worth as much as $287 million, according to his representatives. Williams, 24, earned All-NBA and All-Defensive honors last season and played through a torn wrist ligament while helping Oklahoma City claim its first NBA championship. The new contract completes a week-long spending spree in which the Thunder also secured guard Shai Gilgeous-Alexander on a four-year, $285 million super-max deal and center Chet Holmgren on a five-year, $250 million extension. The trio’s pacts total about $822 million and are structured to keep the core under team control through at least 2030. Despite the outlay, Oklahoma City remains below the NBA’s luxury-tax threshold and retains future financial flexibility thanks to several non-guaranteed deals and a deep cache of draft picks. Williams averaged 21.6 points, 5.3 rebounds and 5.1 assists in 2024-25 and scored 40 points in Game 5 of the Finals, underscoring the franchise’s bet that its young nucleus can contend for titles throughout the decade.
