AI bubble fears hit stock markets as Nvidia takes the heat

Antiestéticar of an artificial intelligence bubble has crept into the stock markets and points directly at Nvidia, the company that makes the chips underpinning the rollout of this technology. The question is not whether AI exists, but whether its stock market value has run years ahead of its actual profits.

The warning circulating on social media boils down to an image and a laugh: that of an investor pointing to **Nvidia** as the most visible symptom of the artificial intelligence frenzy. It is not a report from an investment bank or an analyst note. It is a short post, with a link to a news story and a photo of the company, and it is enough to reopen the question running through the trading floors: how much of what is being paid for AI companies reflects real businesses, and how much is expectation that could deflate.

## Nvidia, the thermometer of the frenzy

Nvidia has become the thermometer of this frenzy because its chips are the infrastructure on which large language models are trained. When the market buys the company's shares, it is really betting that demand for AI computing power will not stall. The problem is that this bet is already priced in. Any sign that orders are cooling or that customers are starting to ration their processor purchases is read as a warning that the cycle has peaked.

The comparison with the dotcom bubble of the late nineties is not gratuitous. Back then there was also a technology promising to change everything, companies valued on their story rather than their revenues, and a market that took years to digest the excess. The difference is that Nvidia sells hardware with high margins and steady profits, not just an idea. That does not make it immune to a correction, but it does change the nature of the risk.

## What the market watches to tell a bubble

The market does not question whether AI is a real technology. It questions the price. The indicators being tracked are the usual ones: the ratio between stock market value and expected earnings, the pace of growth in data centre orders, and tech companies' ability to turn AI spending into revenues that justify the investment. If those three pieces fit together, the frenzy is called growth. If any of them breaks, it is called a bubble.

The viral post offers no figures or analysis. Its strength lies in the mockery: laughter as a way of saying something does not add up. In a market that has been rising for months with AI as its banner, that gesture works as a gauge of nervousness. It proves nothing, but it is a reminder that bubbles do not burst when everyone sees them coming, but when the last person who bought in good faith finds there is no one left to sell to.

## Laughter as a sign of nerves

Bubbles are best recognised in hindsight. While they last, most participants have reasons to believe this time is different. The warning spreading on social media is not analysis, it is a mood. And moods, in the stock market, move money. That a short, mocking post about Nvidia is circulating alongside links to financial news says something about the atmosphere: there are investors starting to look at the price of AI with the same distrust they once applied to the dotcoms.

None of this means a correction is imminent or that Nvidia is about to collapse. It means the debate has stopped being technical and has entered everyday conversation. When antiestéticar of the bubble reaches social media, the market has already partly priced it in. The useful question is not whether there is a bubble, but how much of the rally depends on AI delivering promises it has yet to prove at industrial scale.
