Their wealth comes from Microsoft stock, wireless networking, mortgage lending, hospitality, venture capital and printing—not simply from owning a team. The available estimates do not support a complete, comparable ranking of every billionaire NBA owner as of October 8, 2026, so the profiles below explain documented fortunes and ownership roles rather than claim a definitive order.
What “richest NBA owner” means
An owner’s estimated personal net worth is not the same as the value of an NBA franchise or the value of that person’s stake in it. Net-worth estimates combine assets such as company shares and private investments, less liabilities, and can change as public markets move or private assets are reassessed. A team’s valuation is a separate estimate; an owner may hold less than the whole team, share control, or have a role that does not disclose an ownership percentage.
That distinction matters when comparing these profiles. Forbes’ March 12, 2026, snapshot of the world’s richest sports-team owners estimated Robert Pera’s net worth at $31.7 billion. The other profiles below do not provide a matching, same-date set of personal net-worth estimates, so that figure cannot be used to establish a complete NBA-owner ranking. The sources also differ in what they disclose about ownership stakes and control.
Selected NBA owners and the sources of their fortunes
| Owner | Documented business or wealth source | NBA role and disclosed details | Comparable net-worth estimate |
|---|---|---|---|
| Steve Ballmer | Microsoft equity and executive career | Purchased the Los Angeles Clippers in 2014; the cited Forbes profile does not establish his ownership percentage. | Not stated in the cited Forbes profile as a comparable dated figure. |
| Robert Pera | Ubiquiti wireless networking | Purchased the Memphis Grizzlies in 2012; Forbes reported he owned 93% of publicly traded Ubiquiti. | $31.7 billion, Forbes’ sports-team-owner snapshot dated March 12, 2026. |
| Dan Gilbert | Mortgage lending and other ventures | Owns the Cleveland Cavaliers; Forbes also identifies him as a StockX cofounder. | Not stated in the cited Forbes profile as a comparable dated figure. |
| Tilman Fertitta | Dining, hospitality, entertainment and gaming | The Houston Rockets’ official front-office page calls him the team’s sole owner; it says he purchased the team in 2017. | Not stated in the cited team source as a comparable dated figure. |
| Joe Tsai | Not established by the cited team biography | The Brooklyn Nets identify him as team governor and chairman of Brooklyn Sports & Entertainment. | Not stated in the cited team biography as a comparable dated figure. |
| Joe Lacob | Venture capital and startup investments | Led the ownership group that bought the Golden State Warriors in 2010; Forbes reports his stake at 25%. | Not stated in the cited Forbes profile as a comparable dated figure. |
| Glen Taylor | Printing business | Forbes identifies him as majority owner of the Minnesota Timberwolves. | Not stated in the cited Forbes profile as a comparable dated figure. |
Steve Ballmer: Microsoft equity
Ballmer joined Microsoft in 1980 and served as its chief executive from 2000 to 2014, according to Forbes. When he retired in 2014, he held 4% of the company’s stock. That substantial public-company stake is central to understanding his fortune; his purchase of the Clippers that same year was a later sports investment, not the source of the Microsoft wealth.
#1 Best Overall
Robert Pera: wireless networking
Pera founded Ubiquiti Networks, a wireless-equipment company, and remains its CEO, according to Forbes. Forbes reported that he owned 93% of the publicly traded company and identified wireless networking as his source of wealth. He bought the Memphis Grizzlies in 2012. The $31.7 billion estimate cited above is Forbes’ figure in its March 12, 2026, sports-team-owner snapshot, not the value of his Grizzlies stake.
Dan Gilbert: mortgages and business ventures
Gilbert cofounded the business that became Rocket Mortgage in 1985. Rocket Companies went public in August 2020, and Gilbert owns the Cleveland Cavaliers. Forbes also identifies him as a cofounder of the resale marketplace StockX. Forbes reported that Rocket originated $101 billion in mortgages in 2024; that is a historical annual figure, not a stated current run rate.
Tilman Fertitta: hospitality and entertainment
The Rockets’ official front-office page describes Fertitta’s business interests as dining, hospitality, entertainment and gaming. It says he bought the team in 2017 for $2.2 billion and is its sole owner. That purchase price records the transaction at the time; it does not establish the current value of either the franchise or Fertitta’s personal wealth.
Joe Tsai: confirmed team leadership, limited fortune detail
The Brooklyn Nets’ official biography identifies Tsai as the team’s governor and chairman of Brooklyn Sports & Entertainment, the umbrella that includes the Nets and Barclays Center. Those roles establish his leadership position, but the cited biography does not explain how he made his personal fortune or give a comparable net-worth estimate. It would be misleading to fill that gap with an unsourced business-origin account.

Forbes says Lacob joined venture-capital firm Kleiner Perkins in 1987 and led investments in more than 50 startup companies. In 2010, he led an ownership group that paid $450 million for the Warriors. Forbes described Lacob’s 25% stake as worth nearly $2 billion net of debt in its profile; that is the profile’s date-sensitive account of his stake, not a current estimate or his total net worth.
Glen Taylor: printing entrepreneurship
Forbes describes Taylor as a self-made printing entrepreneur and identifies him as majority owner of the Timberwolves. The available profile supports that business origin and ownership role but does not provide a date-specific net-worth estimate that can be compared with Pera’s 2026 snapshot.
Rank #4
Why there is no definitive ranking here
A defensible ranking requires a shared estimate date and consistent rules for personal net worth, family holdings, minority investors, control and multiple-team ownership. The sources cited here do not provide a complete roster and comparable figures for all billionaire NBA owners on October 8, 2026. Forbes’ March 2026 figure for Pera is a dated estimate within a sports-owner list; it should not be combined with undated profile figures or a team’s purchase price to manufacture an ordinal ranking.
One useful contrast is ownership language: the Rockets explicitly describe Fertitta as sole owner, while the Nets identify Tsai as governor and chairman of the team’s operating umbrella. These descriptions are not interchangeable with a disclosed percentage stake. Likewise, Forbes’ account of Lacob’s 25% Warriors interest is a stake figure, while Ballmer’s cited Microsoft 4% is a company-shareholding figure at retirement—not his Clippers percentage.
