Richest Sports Owner Buys Diamondbacks Stake

The transaction, which took place in 2024 but was never publicly announced by the Diamondbacks, will fund Chase Field renovations. Walton, 81, worth nearly $146 billion according to Forbes, has no decision-making responsibilities or involvement in operations, serving as a minority limited partner.

The team has publicly committed to put in $250 million toward ballpark improvements, with the club having previously considered bringing in additional investors for flexibility with payroll and future ballpark needs.
