Celtics Sale Gets $1B Investment From Indian Steel Titan Mittal

The CEO of steel giant ArcelorMittal and a member of one of India’s richest families is investing $1 billion into the William Chisholm-led purchase of the Boston Celtics.

Aditya Mittal will likely be the second-largest stakeholder of the 18-time NBA champions and potentially be the alternate governor in the future, according to multiple people familiar with the details. Chisholm will be the largest shareholder and take over as team governor from Wyc Grousbeck after the 2027-28 season.

In March, Chisholm’s group reached a deal to buy the Celtics in two stages, which was the stated goal of the Celtics’ current ownership, led by the Grousbeck family. The deal values the team at $6.1 billion in the first payment, marking the most expensive control sale in sports team history.
