Warren Buffett’s company is on the verge of a $1 trillion valuation — but he may not be celebrating

Berkshire’s sustained growth has made it the seventh-most valuable US public company. It’s worth more than Eli Lilly ($859 billion), Broadcom ($751 billion), and Tesla ($665 billion), but less than Meta Platforms ($1.3 trillion).

Buffett’s net worth has risen $25 billion this year, putting him in eighth spot on the Bloomberg Billionaires Index, worth $145 billion.

Headache

A $1 trillion Berkshire has seemed inevitable for a while, given it had assets worth $1.1 trillion at the end of June. That included $277 billion in cash, Treasurys and other liquid assets and short-term investments.

Buffett, who turns 94 on Friday, might get a kick out of a $1 trillion market cap, but he may also have some misgivings. He’s frequently framed Berkshire’s mushrooming size as a headache, as it’s become harder for him to find high-quality investments large enough to move the dial.

One shareholder asked Buffett during Berkshire’s 2014 annual meeting what a $1.2 trillion Berkshire would look like. The “Oracle of Omaha” seemed concerned about what compelling purchases he could make at that gigantic scale.

“There’s no question that at some point we will have more cash than we can intelligently deploy,” Buffett said, suggesting Berkshire stock might still be attractive to repurchase. That challenge may be on his mind as his company flirts with another milestone valuation.
