Apple has overtaken Nvidia to become the world's most valuable company, a changing of the guard at the top of the stock market that reflects a broader wobble in the artificial-intelligence trade.
By the close on Friday, Apple was worth about $4.88 trillion, narrowly ahead of Nvidia's roughly $4.86 trillion, after Nvidia's shares fell around 3.5%. It was the first time Apple had held the top spot since about April of last year. Nvidia, the maker of the chips that power much of the AI boom, had reigned as the most valuable company since the middle of 2025.
A rotation away from chips
The shift is less about a sudden surge at Apple than about a retreat from Nvidia and its peers. Chip stocks have been falling sharply, with a widely watched semiconductor index down nearly a fifth from its highs and heading for its worst week in more than a year. The sell-off has been driven by a growing question in the market: whether the enormous valuations attached to AI-related companies are justified by the returns the technology will actually produce.
As investors trim their exposure to the most obvious beneficiaries of the AI build-out, money has flowed toward companies seen as steadier or better placed to profit from AI in the hands of consumers. Apple, which had been widely characterised as a laggard in the AI race because it spent far less than rivals on building cutting-edge models, has been a beneficiary of that rotation. What was recently seen as a weakness, its comparative restraint, is now, for some investors, a virtue.
How fleeting a crown?
The lead at the very top has become precarious. Apple and Nvidia are now so close in value that a single day's trading can decide which is ahead, and the gap between them is a rounding error against sums that dwarf the economic output of most countries. That two companies should each be worth close to $5 trillion is itself a measure of how far the AI-fuelled rally has run.
Whether Friday's reordering marks a durable change or a passing moment is the question now facing the market. If the doubts about AI valuations deepen, the rotation away from chipmakers could continue, and Apple's position could firm. If confidence in the AI boom returns, Nvidia, whose chips remain central to it, could quickly reclaim the top spot.
The bigger picture
Beneath the horse race between two giants lies a more consequential story about the mood of the market. For much of the past two years, a handful of AI-linked companies, Nvidia foremost among them, have powered the gains in global equities, and their fortunes have become tightly bound to expectations for a technology still in its early commercial stages.
Friday's session, part of a broader retreat in chip stocks that has rattled markets from Asia to New York this week, suggested that those expectations are being reassessed. It does not mean the AI boom is over; demand for advanced chips remains strong, and the technology continues to advance. But it is a reminder that sentiment can shift quickly, and that even the most dominant company can be dislodged from the summit in the space of a single, jittery week.
