Last year, Jaylen Brown grabbed attention by locking in a five-year supermax extension worth $303.7 million. It was the biggest deal in NBA history at the time. But now, Jayson Tatum has one-upped that with a monster five-year contract worth up to $315 million. The monumental deal makes him the latest member of the NBA’s $300 million club.

Coming off a championship run in the 2023-24 season, this cements Tatum’s spot among the league’s top dogs. In addition, it also fuels his push for more championship glory in the seasons ahead.

Jayson Tatum just made history, securing a five-year deal worth up to $315 million, the biggest contract in NBA history. Kicking in for the 2025-26 season, this deal locks the five-time All-Star in Boston through 2029-30, with a player option and trade kicker put into the mix. Tatum’s earned every bit of that bag, showing why he’s one of the league’s best.

With a player option in the final year of his deal, Jayson Tatum has all the leverage to stick with the Celtics or test free agency. If he keeps leveling up and shows he’s worth an even bigger bag, Boston will have no choice but to re-sign him. Additionally, this contract officially makes Jayson Tatum the highest-paid player in the NBA in terms of contract value. Here’s the current breakdown of the top earners:

Last season, Tatum was a beast, putting up over 26.9 points, 8.1 boards, and 4.9 dimes in the regular season. When the playoffs got tougher, he elevated his game, staying elite with over 25 points, nearly 10 rebounds, and 6.3 assists per game. He might’ve missed out on Finals MVP, but Big Deuce was key to the Celtics, locking down the title. He’s more than just a star—he’s the backbone of this team’s future.
