Before you start looking for billionaire GoFundMe's to contribute to, the world's billionaires are doing just fine, with a collective fortune of $8.5 trillion in 2018 – down from $8.9 trillion the previous year, but still a pretty impressive figure. And in the United States, American billionaires actually went against these worldwide trends, with an increase in billionaire fortunes of about 4.8 percent, swelling their ranks to 749 billionaires in the US. That's thanks in part to the financial success of the tech industry within the US, which itself has 89 American billionaires to its name, with almost $1.3 trillion in various assets belonging to US tech billionaires alone, reportedly almost twice that of what they had just five years ago.
