Berkshire Hathaway revealed that it had roughly $348 billion in cash, cash equivalents, and short-term U.S. Treasuries at the end of the first quarter of 2025. That's the largest cash stockpile in the company's history.

Buffett said he will step down as CEO of Berkshire Hathaway, ending a 60-year run where he became an influential and iconic part of the U.S. economy.

"You're losing one of the most esteemed investors one could argue of all time," a source said of investors' reaction to Buffett's plan to step down.
