Meanwhile, Justin Herbert’s new five-year, $262.5m (£203.6m) extension with the Los Angeles Chargers will make him the NFL’s highest-paid quarterback by annual salary, insiders say.
Brown’s five-year Celtics contract exceeds reigning NBA Finals Most Valuable Player Nikola Jokic’s $264m (£204.9m) deal at Denver Nuggets, which he signed last summer.
The two-time All-Star, 26, averaged career bests in points (26.6), rebounds (6.9) and assists (3.5) during 2022-23 as Boston reached the Eastern Conference finals.
Brown, the third pick in the 2016 NBA draft, will earn $28.5m (£22m) next season before his extension begins in 2024, when he will average $60.8m (£47.1m) per year.
Team-mate Jayson Tatum is eligible for his own supermax extension next summer – which allows a team to re-sign qualified players on deals worth up to 35% of the salary cap, to maximum five-year contracts.

Brown and Tatum combined for 56.7 points per game last season, which is the fourth-most by a duo since the competition’s 1976-77 merger.
Herbert’s Chargers contract surpasses the $52.5m (£40.7m) average annual salary of Lamar Jackson, who signed a five-year, $260m (£201.8m) extension with the Baltimore Ravens this offseason.
The 25-year-old is the only player to top 4,000 passing yards in each of the first three seasons of their career – and no player in NFL history has made more completions (1,316) over the first three campaigns.
From Eugene, Oregon, Herbert was the sixth pick in the 2020 NFL Draft and was named the NFL’s Rookie of the Year 2020-21 following a record-breaking season in which he became the youngest player to throw 30 touchdowns in a single season.
He still had two years remaining on his rookie contract, which would have paid him about $8.5m (£6.5m) this season.
His new deal may not remain the NFL’s highest for long as Cincinnati Bengals quarterback Joe Burrow is due for an extension, which could top Herbert’s figure.
