Forbes has released its 40th annual list of the 400 wealthiest people in the world, and the majority are Americans.
According to the publication, the billionaires' net worths were calculated using stock prices and exchange rates from Sept. 3, 2021.
Notably, the minimum net worth required to make the list was $2.9 billion, up from the previous $2.1 billion cutoff – knocking off 51 billionaires.
So, who topped the list in the U.S.A.?
1. Jeff Bezos
While the Blue Origin, LLC founder stepped down as CEO to become chairman in July, Amazon thrived during the COVID-19 pandemic.
Bezos also owns The Washington Post.
2. Elon Musk
Musk has promised to give more than half of his stake in Tesla as collateral for loans, and Forbes said it had discounted his stake to take the loans into account.
Musk stepped down as chairman of the electric car company in 2018 after making "false statements" that launched a probe by the U.S. Securities and Exchange Commission.
SpaceX, however, is valued at $74 billion, Forbes said.
3. Mark Zuckerberg
His social network has been under scrutiny in recent months and a whistleblower who leaked internal documents to The Wall Street Journal delivered congressional testimony against the tech giant on Tuesday.
Zuckerberg, the subject of the movie "The Social Network," took Facebook public in 2012 and owns around 12% of the company's stock, according to Forbes.
In 2015, Zuckerberg and his wife, Priscilla Chan, pledged to give away 99% of their Facebook stake over their lifetimes.
4. Bill Gates
Bill and Melinda Gates announced in May that they were ending their decades-long marriage, though the two will still co-chair the foundation.
5. Larry Page
Page, CEO until 2005 and from 2011 until 2015, also became the CEO of Google's parent company Alphabet before he stepped down in December 2019.
The reclusive billionaire remains a board member and a controlling shareholder, according to Forbes.
