In Forbes' annual list of the world's richest sports-team owners, six NBA owners cracked the list. Of the top-10 richest owners, four were from the NBA:

Steve Ballmer - Ballmer, who is the owner of the Los Angeles Clippers, comes at No. 2 on the list with a net worth of $68.7 billion. Most of Ballmer's wealth comes from his time as CEO of Microsoft.

Dan Gilbert - The 59-year-old owner of the Cleveland Cavaliers sits right behind Ballmer, at No. 3 on the list with a net worth of $51.9 billion. Gilbert is also the co-founder of StockX, where customers buy and sell shoes, clothing, and accessories.

Robert Pera - Pera is the youngest owner in the NBA right now and comes in at No. 6 on the list. At 43 years old, Pera has a net worth of $18.3 billion. Pera actually bought the Memphis Grizzlies when he was in his 30s.

Joseph Tsai - Tsai, who is No. 10 on the list, became owner of the Brooklyn Nets in 2019, but initially invested back in 2017 when he purchased 49% stake of the team. Tsai has a net worth of $11.6 billion.

This is an encouraging sign for the NBA, as the business is clearly doing well aside from the hardships that were brought along with the COVID-19 pandemic. The league hopes to bounce back from low ticket sales this season, as it has been rumored that the NBA expects arenas to be at full capacity next year.
