French luxury goods tycoon Bernard Arnault fell out of the top 10 list of the world's biggest fortunes, leaving an all-American roster of mostly tech billionaires to dominate the rankings.
Arnault's net worth fell to $143 billion, according to the Bloomberg Billionaires Index, pulling the LVMH founder below Warren Buffett, the 96-year-old philanthropist and chair of Berkshire Hathaway.
