Google CEO: "No company is going to be immune" if AI bubble bursts

What they're saying: If the bubble bursts, "I think no company is going to be immune, including us," Pichai said in what was billed as an exclusive interview.

• "We can look back at the internet right now. There was clearly a lot of excess investment, but none of us would question whether the internet was profound," he told the British broadcaster. "I expect AI to be the same."
• "So I think it's both rational and there are elements of irrationality through a moment like this."

By the numbers: Shares in Google parent Alphabet closed at an all-time high Monday, having risen 51% this year alone.

• Despite Pichai's warning, the stock was up another 0.5% in premarket trading early Tuesday.
• The company is benefitting from surging demand for AI infrastructure, as well as growing consumer adoption of its own platform Gemini.

The bottom line: Investors continue to aggressively buy stocks linked to the AI boom — but they're also asking more questions about how long it can last.
