Jeff Bezos predicted to Amazon employees last week that “one day Amazon will fail,” according to a recording of an internal meeting heard by CNBC.

Bezos added that Amazon’s job was to delay failure for as long as possible by focusing on its customers.

Amazon staffers told CNBC that issues such as government regulation and potential antitrust violations worried them.

Amazon CEO Jeff Bezos made a stunning acknowledgment last week in an all-hands meeting, a recording of which was heard by CNBC.

With the company valued at just shy of $1 trillion and Bezos being the richest man in modern history, the Amazon CEO said his 24-year-old firm was far from invincible.

“Amazon is not too big to fail … In fact, I predict one day Amazon will fail,” Bezos reportedly said when addressing a question about Sears recently going bankrupt. “Amazon will go bankrupt. If you look at large companies, their lifespans tend to be 30-plus years, not a hundred-plus years.”

While history shows that no empire lasts forever, it is unusual for CEOs – particularly a boss of one of the world’s most successful companies – to talk down their firm in such unvarnished terms.

Bezos said that the goal was to delay the inevitable for as long as possible – and that the way to do that was to focus on customers.

“If we start to focus on ourselves, instead of focusing on our customers, that will be the beginning of the end … We have to try and delay that day for as long as possible,” he said.

Several Amazon employees who spoke with CNBC on the condition of anonymity said government regulation and potential antitrust violations were “big concerns” when looking to the future of the company.

“It’s a fact that we’re a large company,” Bezos said in the recording heard by CNBC. “It’s reasonable for large institutions of any kind, whether it be companies or governments, to be scrutinized.”

Amazon this week announced it was going to expand into two new locations for its second headquarters, dubbed “HQ2,” which will mean an increase of roughly 50,000 employees.

Amazon did not immediately respond to Business Insider’s request for comment.
