Warren Buffett has finally joined the exclusive $100bn (£72bn) club that includes Elon Musk, Jeff Bezos and Bill Gates.
The 90-year-old is the chairman of investment firm Berkshire Hathaway, which has seen its shares rise to a record level this year.
On Wednesday his net worth edged above $100bn for the first time.
Regarded as the world’s most successful investor, Mr Buffett has given away billions of his wealth to charity.
While Mr Buffett has been a fixture at the top of the world’s wealth rankings for decades, his personal fortune hasn’t topped $100bn until now.
One reason is his sizeable charitable donations – he has given away more than $37bn in Berkshire Hathaway stock since 2006.
Mr Buffett is a co-founder of the Giving Pledge, a campaign to encourage billionaire philanthropy. Mackenzie Scott, ex-wife of Amazon founder Jeff Bezos, has also signed up to the pledge and gave away more than $4bn of her fortune in just four months last year.
The fifth member of the exclusive cohort is LVMH’s Bernard Arnault and his family.
Facebook co-founder Mark Zuckerburg has just slipped out of the exclusive ranks, according to the Forbes real-time billionaires list.
Mr Buffett’s net worth comes almost entirely from owning about one-sixth of Berkshire Hathaway, a roughly $600bn company.
Its share price is up 15% this year, surpassing $400,000 a share. The investment firm had been struggling in recent years to find deals to spark its growth given its sheer size.
The Omaha-based company is a major shareholder in Apple and other tech stocks that have seen their values surge during the pandemic.
Berkshire Hathaway was a failing textile company before Mr Buffett took control of it 1965. It now owns more than 90 businesses.
