America’s richest sports team owner in 2026 is Steve Ballmer, with a net worth of $156 billion, primarily from his Microsoft stock. Ballmer, who purchased the Los Angeles Clippers in 2014 for $2 billion, now oversees a franchise valued at $7.5 billion following their 2024 move to the Intuit Dome. However, Ballmer faces a one-year NBA suspension due to a salary cap violation involving hidden sponsorship deals for player Kawhi Leonard, alongside a $30 million fine and the loss of five future draft picks, resulting in both league and federal investigations.

Rob Walton, heir to the Walmart fortune, ranks second with $132 billion and leads the ownership group of the Denver Broncos, which was acquired for $4.65 billion in 2022. Walton’s organization plans to build a new $4 billion retractable-roof stadium in Denver, aiming to open by 2031 with additional development of a mixed-use entertainment district. Henry Samueli, co-founder of Broadcom, is third richest with $33.8 billion, thanks in part to a 22% increase in his semiconductor company’s stock value, driven by expectations for massive AI-related revenue growth.

Among other top owners is Miriam Adelson, worth $33.5 billion, who purchased a majority stake in the Dallas Mavericks in 2023. Robert Pera, owner of the Memphis Grizzlies, has seen an impressive 23.3% net worth gain to $29.6 billion, despite the Grizzlies being the NBA’s least valuable team, largely due to the growth of his wireless networking company. Billionaire sports owner Stan Kroenke, managing six major franchises including the LA Rams and Arsenal, holds an estimated $27.6 billion, boosted by his recent $4 billion acquisition of a majority stake in MLB's Los Angeles Angels.

The collective wealth of America’s top 20 sports team owners totals $666 billion, a 10% rise from last year. The group controls franchises across various leagues such as the NFL, NBA, MLS, NHL, and major international soccer competitions, reflecting the intersection of tech, retail, real estate, and investment wealth in today's sports ownership landscape. Newcomers this year include Dan Friedkin, Jimmy Haslam, and Peter Mallouk, while some owners like Miriam Adelson and Dan Gilbert have experienced drops in net worth.
