The figure
$50.5Bas of 1 Jan 2019Wikidata (citing forbes.com)↗staleEvery figure below names its source and the date it describes.
Drawn on a fixed rule from nothing to $1T. The same rule is used everywhere on this site, so two fortunes compared here can be compared with two compared anywhere else.
The figure
This figure is 7 years old. Large fortunes move with the markets daily and nothing here tracks that, so read it as a record of what was published then, not as a current valuation.
