Jeff Bezos, Mark Zuckerberg and Elon Musk have made $115 billion this year

The message from Jeff Bezos: Big Tech’s not so powerful.

The message from his personal fortune: Oh yes it is.

As Bezos and three other technology magnates prepare to defend their businesses at a Congressional hearing on antitrust worries Wednesday, their fast-growing wealth provides a breathtaking measure of their companies’ economic might. The Amazon.com Inc. founder has seen his net worth soar by $63.6 billion this year. On one day this month, it leaped an unprecedented $13 billion. The world’s richest man is now on the cusp of another record: a fortune exceeding $200 billion, according to the Bloomberg Billionaires Index.
