Walton Buys Stake in Diamondbacks

Denver Broncos owner Rob Walton, the richest owner in major US sports, has quietly owned a 10% stake in the Diamondbacks for two years, according to a Sportico report. The transaction, which took place in 2024, valued the franchise at $2 billion.

Walton, the son of Walmart founder Sam Walton, is worth nearly $146 billion according to Forbes. He serves as a minority owner with no decision-making responsibilities. The "bulk of the proceeds" from the stake sale will fund Chase Field renovations, with the team committing $250 million to ballpark improvements.
