NBA's biggest contracts: Jayson Tatum agrees to largest contract in NBA history to stay with Celtics

Jayson Tatum has signed a five-year, $314 million contract extension with the Boston Celtics that will make him the highest-paid player in NBA history, according to a report from The Athletic on Monday.

The new pact will begin with the 2025-26 season and keep the five-time All-Star in Boston through 2029-30 season.

When completed, Tatum’s new, supermax contract will become the largest in NBA history, supplanting the one signed last offseason by teammate Jaylen Brown, when he inked a five-year deal that will pay him up to $304 million.

Tatum, 26, is entering the final years of a five-year, $163 million contract extension he signed with Boston in 2020. He will make $51.4 million next season under his new extension and $71.4 million in the final year for an average of $62.8 million annually.

Tatum averaged 26.9 points, 8.1 rebounds, 4.9 assists and shot 47% from the field, earning All-NBA first-team honors for the third consecutive season. Those numbers grew to 25 points, 9.7 rebounds and 6.3 assists per game during a playoff run in which he eclipsed 30 points six times, including 31 in their championship-clinching Game 5 win over the Dallas Mavericks.

Tatum has been voted an All-Star five times in his seven-year career. The Celtics drafted Tatum with the No. 3 overall pick in the 2017 NBA Draft.
