Thunder, Cason Wallace agree to five-year, $139M extension through 2031-32
Cason Wallace has agreed to a five-year, $139 million rookie-scale contract extension with the Oklahoma City Thunder, ESPN's Shams Charania reported, citing Wallace's agents Jeff Schwartz, Max Lipsett and Marcus Monk of Excel Sports Management. The guaranteed money, the year-by-year structure and any options or incentives were not disclosed.
Yardbarker described the deal as a signing, while Charania and other outlets reported an agreement, and no team announcement of a signing appears in the reporting. According to OKC Thunder Wire, the deal came ahead of the extension deadline for 2023 first-round picks, Monday, Oct. 19, at 5 p.m. CT.
Yardbarker reported that the extension starts in 2027-28 and keeps Wallace from reaching restricted free agency next offseason. OKC Thunder Wire put him under contract through 2031-32 at around $27.8 million a year, inside the range of roughly $25 million to $33 million a year reported before the agreement.
Wallace, 22, is entering the final year of his rookie-scale deal. Yardbarker reported that he started a career-high 58 games last season, most of them in place of an injured Jalen Williams.
In 77 games he averaged 8.6 points, 3.1 rebounds, 2.6 assists and 1.9 steals, shooting 43.2% from the field and 35.1% from three. He led the NBA with 150 steals, made the All-Defensive second team and received Defensive Player of the Year votes.
With Lu Dort gone, Wallace is set to be a full-time starter and the Thunder's top point-of-attack defender, according to Yardbarker and The Oklahoman. This summer the Thunder traded Dort, Aaron Wiggins and Isaiah Joe for a combined seven second-round picks and no players, The Oklahoman reported, leaving them $6.9 million under the second apron with one standard roster spot open.
The Oklahoman also reported that Shai Gilgeous-Alexander's four-year super maximum extension kicks in the same season as Wallace's, and that the Thunder hold 2027-28 team options on Ajay Mitchell, Jared McCain and Jaylin Williams. The reporting does not say where those commitments leave the Thunder against the apron that season.
Per WAGE, Wallace's $5.8 million salary last season ranked 228th among rated players, against production that ranked 75th.
That gap earned a 79 WAGE Score in 2025-26, Smart Money.
The new deal's average would have been the 61st-highest salary in 2025-26, and the ten players paid closest to it that season had a middle production rank of 91st, per WAGE. Those figures describe what those salaries bought that season, not a measure for the new contract.
