The founder and boss of Amazon has seen his wealth swell by $24bn (£19bn) after soaring demand for online shopping sent the firm's share price to a new high.
Jeff Bezos now has a fortune of $138bn, according to the Bloomberg Billionaires Index, cementing his position as the world's richest man.
Amazon has benefited from surging internet shopping by people forced to stay home during the Covid-19 outbreak.
The firm has been recruiting thousands of workers to cope with demand.
However, Amazon has also been criticised by employees in the US over workplace protection against the coronavirus.
Mr Bezos owns an 11% stake in Amazon and on Tuesday, the firm's shares rose by 5.3%.
The family behind retail giant Wal-Mart, which owns Asda in the UK, have also gained during the lockdown.
The Waltons saw their net worth rise 5% this year to $169bn, making them the world's richest family, according to Bloomberg.
