Berkshire Hathaway’s chairman Warren Buffett becomes the world’s sixth centibillionaire with 11 zeros behind his estimated fortune of US$100 billion
- Warren Buffett’s estimated wealth jumped on Wednesday to US$100.4 billion, according to the Bloomberg Billionaires Index
- That makes Buffett the sixth member of the US$100 billion club, a group including Jeff Bezos, Elon Musk and his friend Bill Gates

Now, at 90, his net worth has blown past US$100 billion.
The clan’s combined wealth has grown rapidly, fuelled by government stimulus, central-bank policy and the surging equity market. On Wednesday, President Joe Biden’s US$1.9 trillion Covid-19 relief bill cleared its final congressional hurdle as the House voted to approve the legislation, adding to the US$3 trillion or so in stimulus Washington has already disbursed in the past year.

Berkshire, the source of virtually all of Buffett’s wealth, has had a good start to 2021. The firm’s A shares are up 15 per cent this year, outpacing the 3.8 per cent gain of the S&P 500 Index. That’s been helped by Buffett’s recent push to spend record amounts buying back Berkshire’s own stock, a notable shift for an investor who previously preferred to use the US$138 billion cash pile to buy other businesses or common shares.
