Steve Steglitz is discussing:

US household wealth could fall further through the second half of 2022 to hit $9 trillion in total losses, according to JPMorgan Chase

"According to the report, US billionaires are the biggest losers in the market rout, with their collective wealth having crashed almost $800 billion since its peak in November."

I think this excludes the top billionaires, namely, the Elon Musks, Jeff Bezoses, Bill Gateses, and of course the trillionaire dynasties like the Rothchilds, Rockefellers and Windsors.
