Celtics signing Jayson Tatum to biggest contract in NBA history

According to a league source who spoke with MassLive, Jayson Tatum has agreed to a five-year supermax agreement with the Celtics. Commencing with the 2025–26 season, the contract has a value of $315 million spread over five years. According to a source, Tatum should receive a player option in the fifth year of the contract. The transaction was initially reported by Bleacher Report’s Chris Haynes.

Along with Jaylen Brown, Tatum is the only NBA player among his teammates to sign a supermax contract. Tatum made an All-NBA team his first two seasons, which qualified him for the supermax. His current deal has one year left on it before a player option becomes available.

Tatum shot 47.1 percent from the field and 37.6 percent from three during the regular season, averaging 26.9 points, 8.1 rebounds, and a career-high 3.9 assists. For the second consecutive year, he was selected to the All-NBA first team this season.

The franchise reached a second extension on Monday with Tatum’s contract. On Monday afternoon, Derrick White and Boston reached an agreement on a four-year, $125 million contract extension, which will keep him under contract for the following five years. These large contracts will prevent Boston from controlling its core for the foreseeable future, but maintaining the team will come with a hefty tax burden.

The following lists Boston’s schedule for the 2025–2026 season:

Tatum Jayson: $54.1 million

$53.6 million for Jaylen Brown

Holiday Jrue: $32.4 million

Porzingis Kristaps: $30.7 million

$28.1 million is Derrick White’s

$7.2 million for Payton Pritchard

Scheierman Baylor: $2.5 million

$208.6 million in total to seven players

Tatum’s position as the team’s premier player for the balance of the decade is secure, but tough choices regarding Boston’s squad may eventually need to be made. After agreeing to a new contract, the All-Star will compete for Team USA at the Olympics in Paris later this month alongside colleague Jrue Holiday.
