Warnings of AI Bubble Grow Louder as Big Investors Dump Nvidia Stock
"I’m very nervous about the size of these investments in these data centers," one tech CEO said.
Nov 18, 2025
Tech industry insiders are growing more wary of a financial bubble in the artificial intelligence industry that many analysts have been warning could tip the global economy into a severe recession.
Sundar Pichai, CEO of Google parent company Alphabet, said in an interview with BBC published Tuesday that he believes the speculation currently pumping up investment in AI is akin to the kind of speculation that occurred in the late 1990s ahead of the dot-com stock crash.
"We can look back at the internet right now," he told BBC. "There was clearly a lot of excess investment, but none of us would question whether the internet was profound. 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."
PIchai said that he believed his firm would be well positioned to weather the bursting of an AI bubble, although he also cautioned that "I think no company is going to be immune, including us," were such a scenario to occur.
Sebastian Siemiatkowski, CEO of global payments network Klarna, told the Financial Times on Monday that while he still believed in the potential of AI, he also thought many of the biggest players in tech were vastly overspending to build out infrastructure that would not be needed to power the technology.
Siemiatkowski pointed to advances made this year by Chinese AI firm DeepSeek in vastly reducing the power needed to run AI as evidence that the energy-devouring data centers being constructed across the US would be a massive overbuild.
"I think OpenAI can be very successful as a company but at the same time I’m very nervous about the size of these investments in these data centers,” he said. "That’s the particular thing that I am concerned about."
Some major investors are also signaling that the boom may be over for AI.
MarketWatch reported on Monday that Palantir chairman Peter Thiel's hedge fund, Thiel Macro LLC, dropped all its shares in Nvidia, the US-based semiconductor giant that manufactures most of the chips used to power AI. The move by Thiel was revealed just one week after Japanese investment holding company SoftBank disclosed that it had divested its entire $5.8 billion stake in Nvidia.
Nvidia has also become a target for investor Michael Burry, who famously made a fortune by short-selling the US housing market ahead of the 2008 financial crisis, and who recently revealed that his firm was making bets against Nvidia and Palantir.
Concerns about a potential AI bubble have roiled global markets this week, and all major US stock indexes once again traded lower on Tuesday, marking the fourth consecutive losing session.
According to the Wall Street Journal, the current selloff is being driven by investors spooked about "lofty valuations and a pile-up of debt to build data centers," and the paper pointed to a new survey showing that "45% of fund managers see an AI bubble as the top 'tail risk' for markets" right now.

Warning Against Taxpayer Bailout for Big Tech, Critics Fume Over OpenAI Execs' Talk of Government Loans
"Big Tech is building a mountain of speculative infrastructure," warned one critic. "Now it wants the US government to prop up the bubble before it bursts."
Nov 06, 2025
Tech giant OpenAI generated significant backlash this week after one of its top executives floated potential loan guarantees from the US government to help fund its massive infrastructure buildout.
In a Wednesday interview with The Wall Street Journal, OpenAI chief financial officer Sarah Friar suggested that the federal government could get involved in infrastructure development for artificial intelligence by offering a "guarantee," which she said could "drop the cost of the financing" and increase the amount of debt her firm could take on.
When asked if she was specifically talking about a "federal backstop for chip investment," she replied, "Exactly."
Hours after the interview, Friar walked back her remarks and insisted that "OpenAI is not seeking a government backstop for our infrastructure commitments," while adding that she was "making the point that American strength in technology will come from building real industrial capacity, which requires the private sector and government playing their part."
Despite Friar's walk-back, OpenAI CEO Sam Altman said during a podcast interview with economist Tyler Cowen that released on Thursday that he believed the government ultimately could be a backstop to the artificial intelligence industry.
"When something gets sufficiently huge... the federal government is kind of the insurer of last resort, as we've seen in various financial crises," he said. "Given the magnitude of what I expect AI's economic impact to look like, I do think the government ends up as the insurer of last resort."
Friar and Altman's remarks about government backstops for OpenAI loans drew the immediate ire of Robert Weissman, co-president of consumer advocacy organization Public Citizen, who expressed concerns that the tech industry may have already opened up talks about loan guarantees with President Donald Trump's administration.
"Given the Trump regime’s eagerness to shower taxpayer subsidies and benefits on favored corporations, it is entirely possible that OpenAI and the White House are concocting a scheme to siphon taxpayer money into OpenAI’s coffers, perhaps with some tribute paid to Trump and his family." Weissman said. "Perhaps not so coincidentally, OpenAI President Greg Brockman was among the attendees at a dinner for donors to Trump’s White House ballroom, though neither he nor OpenAI have been reported to be actual donors."
JB Branch, Public Citizen’s Big Tech accountability advocate, said even suggesting government backstops for OpenAI showed that the company and its executives were "completely out of touch with reality," and he argued it was no coincidence that Friar floated the possibility of federal loan guarantees at a time when many analysts have been questioning whether the AI industry is an unsustainable financial bubble.
"The truth is simple: the AI bubble is swelling, and OpenAI knows it," he said. "Big Tech is building a mountain of speculative infrastructure without real-world demands or proven productivity-enhancing use cases to justify it. Now it wants the US government to prop up the bubble before it bursts. This is an escape plan for an industry that has overpromised and underdelivered."
An MIT Media Lab report found in September that while AI use has doubled in workplaces since 2023, 95% of organizations that have invested in the technology have seen "no measurable return on their investment."
Concerns about an AI bubble intensified earlier this week when investor Michael Burry, who famously made a fortune by short-selling the US housing market ahead of the 2008 financial crisis, revealed that his firm was making bets against Nvidia and Palantir, two of the biggest players in the AI industry.
This has led to some AI industry players to complain that markets and governments are undervaluing their products.
During her Wednesday WSJ interview, for instance, Friar complained that "I don’t think there’s enough exuberance about AI, when I think about the actual practical implications and what it can do for individual."
Nvidia CEO Jensen Huang, meanwhile, told the Financial Times that China was going to beat the US in the race to develop high-powered artificial intelligence because the Chinese government offers more energy subsidies to AI and doesn't put as much regulation on AI development.
Huang also complained that "we need more optimism" about the AI industry in the US.
Investment researcher Ross Hendricks, however, dismissed Huang's warning about China winning the AI battle, and he accused the Nvidia CEO of seeking special government favors.
"This is nothing more than Jensen Huang foaming the runway for a federal AI bailout in coordination with OpenAI's latest plea in the WSJ," he commented in a post on X. "These grifters simply can't be happy making billions from one of the greatest investment manias of all time. They'll do everything possible to loot taxpayers to prevent it from popping."
