In just one year, Michael Dell’s net worth soared by $3.3 billion — more than the entire net worth of fellow Austin billionaire Thai Lee.

The 2020 edition of the Forbes 400, which ranks the 400 richest Americans, shows Dell’s net worth as of July 24 stood at $35.6 billion. That makes him the richest Austin resident and the 18th richest American. Last year’s Forbes 400 pegged Dell’s net worth at $32.3 billion.

By comparison, Forbes estimates this year’s net worth for Lee, a tech entrepreneur, at $3.1 billion. That’s up from $3 billion in 2019. This year, she sits at No. 268 among the richest Americans.

For years, Dell, chairman and CEO of the Round Rock-based tech company that bears his name, has dominated the billionaire ranks in Austin. Today, Dell and Lee are among eight Austin billionaires on the Forbes 400, which was released September 8.

"Pandemic be damned: America’s 400 richest are worth a record $3.2 trillion, up $240 billion from a year ago, aided by a stock market that has defied the virus," Forbes writes.

Here’s the full list for Austin:

• Michael Dell, tech magnate — $35.6 billion, No. 18. Last year: $32.3 billion.
• Robert Smith, private equity entrepreneur— $6.2 billion, No. 125. Last year: $5 billion.

Walmart heiress Alice Walton of Fort Worth retained her status as the richest Texan and America’s richest woman, with a net worth estimated this year at $62.3 billion. That compares with $51.4 billion in 2019. She moved up from No. 11 last year to No. 10 this year in the Forbes ranking of the richest Americans.

From 2019 to 2020, Walton’s net worth jumped by $10.9 billion. To give you an idea of how much money that is, the size of the economy in Africa’s Republic of Congo totaled $10.8 billion in 2019. Walton’s entire net worth is slightly more than the size of the Costa Rican economy (nearly $61.8 billion in 2019).
