The Forbes World’s Billionaires list is a snapshot of wealth using stock prices and exchange rates from March 11, 2022. We value a variety of assets, including private companies, real estate, luxury cars, art and more. We don’t pretend to know each billionaire’s private balance sheet (though some provide it). When documentation isn’t supplied or available, we discount fortunes. For a detailed meth- odology, see forbes.com/billionaires.
