Analysts weigh whether AI sell-off is froth removal or a bubble about to burst

AI investment expected to reach $1 trillion in 2026, Goldman Sachs says

Is the artificial intelligence gold rush coming to an end, or is this simply a reality check? That is the question hanging over investors after steep falls on the world’s stock markets this week.

The sell-off in the United States on Thursday was most dramatic on the Nasdaq, home to technology industry titans such as Alphabet, Nvidia, Meta and Apple. It followed sweeping gains by Democrats in this week’s midterm elections, which gave the party full control of Congress. The Nasdaq Composite stood at 24,315.0 in the Nov. 6, 2026, record of the FRED database maintained by the Federal Reserve Bank of St. Louis.

The falls seen on stock markets over the past 24 hours would appear to have been triggered by the midterm results. A number of leading Democrats campaigned against the unhindered expansion of data centers, the facilities that have underpinned the growth of artificial intelligence, and fears that the election outcome will lead to more regulation of AI appear to have sparked fear among investors. But concerns that technology firms have become overvalued were being expressed long before the elections.

Tudor Brown, co-founder of the British-based technology firm Arm Holdings, points out that “stock values are based on future earnings not present earnings.” If the rewards are not likely to be as great as expected, some investors will choose to sell up. Still, Brown thinks the impact of the current sell-off will be limited. Share valuations, in his view, were inflated by expectations of “almost infinite AI growth,” which have been followed by “a bit of a panic.”

“There is a natural floor to this,” he said. “After that it will reflect I think that actually there’s still a lot of money being made in these companies.”

Nandini Roy Choudhury of Future Market Insights thinks investors will assess whether the political shift could result in restrictions on data center construction, energy consumption and the deployment of AI technology. She does not expect an immediate, widespread recovery in tech stocks, saying traders are likely to be more selective and favor firms with stronger balance sheets.

The boom traces to the release of ChatGPT by OpenAI in late 2022, which is widely seen as having generated massive public and corporate interest in the practical uses of AI and as having set off a modern-day gold rush. Investors flocked to put their money into companies producing computer chips and networking infrastructure, building data centers and providing the energy to power them, as well as developing the AI itself. The value of technology companies soared.

The boom continued into this year. Investment in AI is expected to reach $1 trillion in 2026 alone, according to research by Goldman Sachs. The sector has drawn in so much available cash that other industries have seen their own borrowing costs increase as a result.

Investors want returns, and in recent months concerns have grown about whether the AI boom can produce the expected riches. Those worries have surfaced at a time when public comments from AI researchers casting doubt over the safety of the technology — even suggesting it could represent an existential threat to humanity — have grabbed headlines and fueled speculation that a clampdown could lie ahead.

The Trump administration has been all-in on AI, or “super intelligence” as the president likes to call it. Many leading Democrats, by contrast, have tapped into grassroots concerns about the expansion of data centers and their impact on local communities. Those concerns focused largely on the facilities’ high consumption of water and electricity, which many feared would push up household bills, as well as the noise, use of land and general disruption associated with them.

A Gallup poll published in May showed 71% of Americans would oppose the building of a data center in their community. The figure for a nuclear power station was 53%.

James Talarico, who won the Senate race in once staunchly Republican Texas, was among the candidates who tapped into that skepticism. “While we want to protect America’s leadership in artificial intelligence, we are still grappling with how it will affect everything from how we work to how our children learn,” he said. “We must protect Americans and establish clear, consistent laws for businesses.”

With control of both houses of Congress, Democrats are now expected to challenge the president’s technology agenda more vigorously while introducing legislation that could curb the expansion of the industry.

In Texas, Democratic Governor-elect Gina Hinojosa campaigned against data centers and pledged a moratorium on the construction of new facilities. Her win could present opposition to the tech multi-billionaire Elon Musk, who has moved large parts of SpaceX’s and Tesla’s operations to the state, for years a Republican stronghold. The Tesla boss had spent nearly $450 million backing Republican campaigns in the midterms.

The question now is whether this is simply the removal of froth from an over-exuberant market, or a sign that the AI rush is a bubble about to burst, with much wider consequences.
