Walton Buys Stake in Diamondbacks

The transaction, valued at $2 billion, took place in 2024 but was never made public by the Diamondbacks. Walton, 81, a son of Walmart founder Sam Walton, is worth nearly $146 billion according to Forbes.

As a minority owner and limited partner, Walton has no decision-making responsibilities or involvement in operations. The "bulk of the proceeds" went toward Chase Field renovations, with the team having publicly committed $250 million to ballpark improvements.
