Cason Wallace, Thunder Reportedly Agree to $139M Contract Extension, Updated Salary Cap, Apron Space

Cason Wallace has been an important secondary contributor for the Oklahoma City Thunder throughout his career, and they made sure that won't change in the immediate future on Sunday.

Oklahoma City and the guard agreed to a five-year, $139 million rookie-scale contract extension, per ESPN's Shams Charania.

The Thunder are $51.5 million over the cap and had $6.9 million remaining in second apron space in 2026-27, per Spotrac . However, team will have a tough budget in 2027-28.

This comes after the Thunder exercised the $7.4 million club option for the 2026-27 season on his contract in October 2025. That previous move made sure he was not scheduled for restricted free agency until the summer before the 2027-28 campaign.

Now there is even more long-term certainty for the guard following this development.

And that is welcome news for the Thunder as well considering his overall importance as a role player for one of the best teams in the league.

Wallace averaged 6.8 points per game as a rookie in 2023-24 while largely coming off the bench and then saw an increase in usage in his second season. The end result was 68 regular-season appearances, 43 of which were starts, and he averaged 8.4 points, 3.4 rebounds, 2.5 assists and 1.8 steals per game while shooting 47.4 percent from the field and 35.6 percent from deep.

That was just the start of things for the Kentucky product, as he helped lead the Thunder to the championship during the 2024-25 campaign.

His ability to hit from deep plays well alongside Shai Gilgeous-Alexander, as the gravitational pull from the MVP guard often leads to open looks on the wings for his teammates. But Wallace does far more than just hit outside shots.

He is an elite defender as well and consistently guards some of the best playmakers on the opposing side.

In fact, he finished seventh in Defensive Player of the Year voting in his third season in the league in 2025-26 while averaging a career-high 8.6 points per game and connecting on 35.1 percent of his triples on the offensive end.

The Thunder finished with the best record in the league at 64-18, although they lost to the San Antonio Spurs in the Western Conference Finals even though Wallace averaged a solid 10.1 points per game in the series.

With Wallace now signed for the immediate future, he will look to continue doing his part to help the Thunder dominate the NBA and contend for more championships.
