Boston Celtics' majority owner puts team up for sale weeks after NBA championship

The ownership group behind the Boston Celtics, Boston Basketball Partners LLC, has announced plans to sell the team. The majority stake is expected to be sold by the end of 2024 or early 2025, with the remaining sale closing in 2028. The Celtics, one of the most successful and widely followed teams in U.S. professional sports, recently won their 18th championship. The team was acquired by Wyc Grousbeck and his group in 2002 for $360 million. Grousbeck will continue as the team’s governor until the second closing in 2028. The sale comes amid rising sports franchise valuations.
