Walton Buys Stake in Diamondbacks

Walton, 81, son of Walmart founder Sam Walton, made the purchase in 2024 but it was never publicly disclosed by the team. The "bulk of the proceeds" went toward Chase Field renovations, with the team having committed $250 million to ballpark improvements.

As a limited partner, Walton has no decision-making responsibilities or involvement in operations. The move aligns with previous statements by team president Derrick Hall who had indicated the possibility of bringing in additional investors for ballpark funding needs.
