Elon Musk has reclaimed his title as the world's richest person, knocking the boss of luxury goods giant LVMH, Bernard Arnault, off the top spot.
His net worth has soared by $55.3bn (£44.44bn) since January to $192bn, after a rise in the value of his electric car company Tesla.
Mr Arnault's fortune has fallen by $24.5bn to $187bn, per Bloomberg's Billionaires Index.
He is followed by Jeff Bezos and Bill Gates in third and fourth positions.
Mr Arnault, 74, had overtaken Mr Musk, 51, on the the rich list in December when shares in LVMH jumped as demand for luxury goods rebounded.
At the same, shares in Tesla - the company from which Mr Musk
derives most of his wealth - fell sharply amid concerns that his takeover of
the social media platform Twitter was affecting his leadership.
However, Tesla shares have bounced back by almost 92% since the start
of this year as investor nerves have eased and Mr Musk has announced his
replacement as Twitter chief executive.
His visit to China this
week to discuss Tesla has also sparked excitement, while the car firm is
benefiting from the rise in interest in artificial intelligence.
By contrast, LVMH - which owns brands including Louis Vuitton
and Christian Dior - has gone into reverse.
After hitting a
record high in April, its shares have fallen sharply and are down 16% since
the start of the year.
Mr Arnault, who co-founded the luxury
goods giant in 1987, owns a majority stake in the business, which is
Europe's most valuable firm.
In January, the Frenchman appointed
his daughter Delphine Arnault, 47, as head of his fashion house Dior as part
of a shake-up at LVMH.
All five of Mr Arnault's children hold
management positions at brands in the group.
According to
Bloomberg, Amazon founder Jeff Bezos is the world's third richest person
with a fortune of $146bn. Mr Gates, who co-founded Microsoft, is worth
$126bn.
