Substantial investments in AI are suggesting a global financial bubble that may soon burst, exposing companies and investors to the risk of unmanageable debts unable to be serviced by the scant revenues from current AI applications. But what implications does this have for the future of the technology fueling this financial madness?

Recent warnings have emerged globally about the danger of an AI bubble. The Bank of England, the CEO of JP Morgan Chase, and even OpenAI’s Sam Altman have all cautioned against the current trends. “This isn’t merely a stock market bubble; it encompasses investment and public policy bubbles,” asserts David Edgerton from King’s College London.

The interconnected nature of deals among leading AI firms has raised concerns. Take Nvidia, for instance, which manufactures the GPU chips propelling the AI surge; it recently poured up to $100 billion into OpenAI, while maintaining its own data centers filled with Nvidia chips. Ironically, OpenAI also holds a stake in Nvidia’s competitor, AMD.

According to Morgan Stanley Wealth Management, an estimated $400 billion is spent yearly on data centers, leading to increasing worries about the impending burst of the AI bubble. In the second quarter of this year, the US GDP saw a 3.8% increase, but as Harvard’s Jason Furman points out, excluding data center investment, the actual growth was merely 0.1% in the first half of the year.

Carl Benedikt Frey, a professor at Oxford University, notes that such frenetic deal-making isn’t uncommon in the technology sector’s history. “Overbuilding tends to happen; it unfolded during the railroad boom and again during the dot-com bubble,” he explains.

The concern is whether the fallout from the AI bubble will impact only the companies involved or whether it could ripple through the economy. Frey indicates that many data centers being constructed “off-balance sheet” entail creating new companies to bear the associated risks and potential rewards, usually supported by external investors or banks.

This opacity leaves many unsure about who might be negatively affected. The funding for data centers could be rooted in investments from influential tech billionaires or major banks, and substantial losses might trigger a banking crisis, adding turbulence to the economy. “While a financial crisis isn’t immediately on the horizon, the uncertainties breed potential risks,” Frey comments.

Benjamin Arold, a professor at Cambridge University, states that the crucial factor is the profit-to-company valuation ratio, revealing the disconnect between public perception and the actual financial performance of companies. Such metrics are, he warns, red flags for contemporary tech firms.

“We haven’t seen price levels like this in 25 years; it’s reminiscent of the dot-com bubble,” Arold warns. “It may work out in the end, but investing in it feels risky.”

James Poskett from the University of Warwick argues that the AI sector may face a downturn that could lead to many companies going out of business. However, he believes this doesn’t spell the end for the technology itself. “It’s essential not to conflate that with the notion that the technology itself is flawed or redundant,” Poskett emphasizes. “AI could falter, yet it won’t vanish.”

Poskett suggests we may end up with valuable technology, much like how the collapse of various railroad companies in the past left the legacy of a robust rail system, or how the dot-com bust concluded with an extensive fiber-optic infrastructure.

For consumers, the fallout from the AI bubble could translate to fewer choices, potentially higher costs, and a slower rate of technological advancements. Utilizing an expensive tool like GPT-5 for tasks such as email creation resembles using a sledgehammer to crack a nut and may reveal the concealed costs associated with its use, obscured by the present AI race. “There’s currently a lot of ‘free lunch,’ but eventually, these companies will need to start turning a profit,” Poskett notes.
