Austin has had its fair share of billionaires for years now, but this year's Forbes rankings added two very-talked-about tech moguls: Elon Musk and Whitney Wolfe Herd.

While Musk is no stranger to Forbes' billionaire's list, Herd is spick-and-span new, only recently gaining the wealth to join the other local billionaires on the list this year when global dating app Bumble made its market debut.

Here's how Austin's billionaire's ranked in Forbes' 2021 world's billionaire's list:

No. 2 (+29) Elon Musk, $151 billion

Tesla CEO and new Austinite Musk landed in second place, falling behind Amazon founder Jeff Bezos after briefly overtaking him earlier this year but easily supplanting longtime richest Texan Alice Walton. His worth is largely fueled by Tesla and SpaceX, according to Forbes. This is more than six times his estimated net worth in 2020 and has allowed him to climb several ranks.

No. 30 (+3) Michael Dell, $45.1 billion

While getting knocked out of his spot as wealthiest Austin resident, Chairman and CEO of Dell Technologies Michael Dell still got richer. His wealth almost doubled from last year after dropping in value last year.

No. 451 (-121) Robert F. Smith, $6 billion

Founder of the private equity firm Vista Equity Partners, Robert F. Smith is the wealthiest Black man, although rapper Kanye West almost took the throne last month. Although going down in Forbes' ranking, he is worth $11 billion more than last year. Last fall, Smith reached a $140 million settlement with the U.S. Justice Department to resolve issues involving undeclared offshore accounts.

No. 622 (-6) Bert "Tito" Beveridge, $4.6 billion

Founder of Tito's Vodka Bert Beveridge's net worth went up since last year by about $1.4 billion, although he went down in Forbes' rankings.

No. 956 (-276) Thai Lee, $3.2 billion

CEO of the IT provider SHI International, Thai Lee is the wealthiest woman in Austin. She is ranked No. 8 on Forbes' America's self-made women 2020 list.

No. 1,008 (-328) Joseph Liemandt, $3 billion

Founder of the investment firm ESW Capital, Joseph Liemandt's net worth has stayed stagnant the past three years.

No. 1,174 (-526) John Paul DeJoria, $2.7 billion

Both in the alcohol and beauty industry, John Paul DeJoria is the founder of tequila maker Patron Spirits Co. and co-founder of the hair care company John Paul Mitchell Systems. His net worth went down this year by less than $1 billion after increasing the year before.

No. 1,249 (-341) Jim Breyer, $2.5 billion

One of Facebook's first venture investors, Jim Breyers credits investing in Facebook in early 2005 and helping Mark Zuckerberg recruit now-Facebook COO Sheryl Sandberg as two of the best decisions of his business career.

No. 1,750 (-401) David Booth, $1.8 billion

Co-founder of Dimensional Fund Advisors which he launched in 1981, David Booth began a decades-long experiment in applying academic theory to real-world investing, he told Forbes.

No. 2,263 (new to the list) Whitney Wolfe Herd, $1.3 billion

And finally, Herd, co-founder and CEO of the dating app Bumble, made her debut on the list after an initial public offering of Bumble took the company to $43 a share, raising more than $2 billion for the company. Herd has been listed on Forbes self-made woman list two years in a row.
