As investments in artificial intelligence continue to soar, some analysts are raising alarms about a looming bubble that could burst and trigger broader market declines. Others, however, say they’ve never been so sure that it is a growing opportunity.

So who is right? Well, on Wall Street, there’s a pick-your-flavor opinion for whatever it is you want to back, so we can’t determine that. But we can show you what each side is thinking.

Firstly, that the sector is overvalued. Analysts and investors and even company CEOs of AI giants have expressed concerns that current valuations of AI-related stocks may be disconnected from their underlying fundamentals.

The rapid rally in companies involved in AI hardware, software, and infrastructure—including chipmakers, cloud providers, and automation firms—has driven valuations to levels that many consider unsustainable.

Why does that matter? Because everything that goes up must eventually come down.

That means that recent market volatility and warnings from veteran investors suggest that a sudden reassessment of valuations could result in a significant downturn, similar to past technology and internet bubbles. 

The hype men

Secondly, that growth is why those valuations are worth it.

Despite recent concerns about overvaluation and a possible slowdown in AI-related growth, UBS analysts reaffirmed their positive outlook on the sector this week, buoyed by Nvidia’s hotly anticipated quarterly results.

In a note released after Nvidia reported earnings that exceeded expectations (but only just barely), UBS said that the core case for AI investment remains intact.

“While valuations might appear stretched in the short term, the fundamental need for AI technology across industries continues to grow,” UBS wrote in a note to investors.

The firm highlighted Nvidia’s role as a leader in semiconductor and AI infrastructure, emphasizing that the company’s robust revenue growth, which is projected at 48% for the current quarter, is a sign for ongoing demand for AI hardware and software solutions.

Analysts also pointed out that the broader enterprise move toward integrating AI is supported by increasing capital spending, which bodes well for the sector’s long-term prospects.

“Investors should maintain conviction,” UBS added, “as the demand for scalable, high-performance AI platforms is only poised to accelerate.”

Market experts agree that while short-term volatility is inevitable, the fundamental structural drivers, such as the adoption of AI in cloud computing, autonomous vehicles, and enterprise AI, suggest the sector’s growth story remains robust for the foreseeable future.

The haters

Not everyone is as bullish on AI as UBS.

Take OpenAI CEO Sam Altman, a man who is watching billions of dollars being poured into his competitors. Altman caused a major market rout when he said that investors are getting “over-excited” about AI.

“Are we in a phase where investors as a whole are over-excited about AI? My opinion is yes. Is AI the most important thing to happen in a very long time? My opinion is also yes,” He told The Verge, adding that he thinks that some valuations of AI start-ups are “insane” and “not rational”.

Investors are also increasingly wary after reports that Meta is considering a “downsizing” of its artificial intelligence division, with some executives expected to depart.

This potential shift marks a notable departure from Meta CEO Mark Zuckerberg’s recent heavy investments in transforming the company’s AI operations.

Over the past few months, Zuckerberg has championed a major overhaul of Meta’s AI strategy, emphasizing its critical role in enhancing user experience and competing with rivals like OpenAI and Google.

The New York Times cited sources close to the company, indicating that the restructuring could lead to significant layoffs or a shakeup in leadership.

The planned changes have raised questions among market watchers about whether Meta’s aggressive AI ambitions are being reassessed, or if internal challenges are forcing a strategic pivot. The move signals a period of uncertainty for Meta’s AI efforts, which had been a key part of Zuckerberg’s vision for the company’s future growth

So full speed ahead or hit the brakes?

While some experts acknowledge the transformative potential of AI, they caution investors to remain vigilant and avoid chasing speculative gains that lack proper valuation.

“The risk is that we are in a man-made bubble that will eventually burst, causing widespread damage,” said industry veteran Michael Johnson.

“Even when the dotcom bubble burst, there were a handful of fairly obvious winners that eventually came roaring back,” said CNBC‘s Jim Cramer. “If you gave up on Amazon in 2001, you missed the $2 trillion (£1.4 trillion) boat.”

Cramer has been investigated by the Securities and Exchange Commission at least once, and has also drawn criticism for past comments on market manipulation.

Perplexity, the AI startup that wants to pay publishers for their scraped content, launched a new agentic web browser called “Comet” in July. It arrived with an impressive $200-per-month subscription cost, available for Perplexity Max and some Perplexity Pro subscribers.

According to Perplexity, “The security features, privacy, and compliance standards your business demands are already built into the core of Comet.” Now, the AI-powered browser is coming under fire for security vulnerabilities discovered by Brave and Guardio (via Tom’s Hardware).
