Spurs forward Julian Champagnie has agreed to a three-year, $45 million contract extension that will keep him with the San Antonio Spurs through the 2028-29 season. The deal was reported by ESPN’s Shams Charania on Monday.

San Antonio opted to decline Champagnie's $3 million team option for the upcoming season to facilitate the new agreement. The contract includes $42 million in new money and is structured to provide Champagnie with early financial security while offering the team flexibility as it pursues a championship.

Champagnie, who turned 25 on Monday, has become a key piece of the Spurs' young core since being waived by the Philadelphia 76ers in 2023. During the Spurs' recent run to the NBA Finals, he posted career highs in minutes played (27.6 per game), points (11.1 per game), and rebounds (5.8 per game). He played in all 82 regular-season games and set a franchise record with 195 three-pointers made in a single season.

After moving into the starting lineup in February, Champagnie was part of a Spurs team that became the NBA's best in the second half of the season. Head coach Mitch Johnson described Champagnie as an "unsung hero" for the team, which ultimately fell to the New York Knicks in five games in the NBA Finals. In the Western Conference Finals against the Thunder, Champagnie averaged 17.3 points over the final three games of the series.

Champagnie entered the NBA undrafted out of St. John's in 2022 and initially signed a two-way contract with Philadelphia. The 76ers waived him the following year to make room for another player. The Spurs claimed Champagnie two days later, and he has now committed his future to the team.
