Nvidia sheds $177bn in a day as AI selloff deepens

Summary

• Nvidia fell 3.36% Monday, erasing roughly $176.6bn in market value, GuruFocus reported.
• Broadcom lost 4.77%, AMD 4.4%, and SoftBank dropped 10.7% in Tokyo trading.
• The selloff pairs AI valuation doubts with bond yields above 5% and oil above $100.

The latest

Nvidia led a broad selloff in artificial-intelligence stocks on Monday, 14 September 2026, closing down 3.36% and erasing about $176.6bn of market value, according to GuruFocus. Broadcom fell 4.77% and AMD 4.4%, while the wave carried into Asia with SoftBank down 10.7% in Tokyo. Nvidia slid a further 3% in Tuesday pre-market trading.

Details

• The numbers: GuruFocus put Nvidia's single-session decline at 3.36%, equal to roughly $176.6bn of market capitalisation. Broadcom shed 4.77% and AMD 4.4% on the same day, making the losses a sector-wide move across chip designers rather than a single-name repricing.
• The Asia leg: SoftBank, one of the most heavily AI-exposed listed holdings in Japan, dropped 10.7% in Tokyo — a decline roughly three times the size of Nvidia's, per GuruFocus. The move showed the selling was not confined to US trading hours.
• Tuesday follow-through: Nvidia extended losses by about 3% in pre-market trading on Tuesday, indicating the selling did not stop at Monday's close. No stabilisation level was identified in market reporting.
• The trigger cited: Market reports attributed the wave to public warnings from chief executives of major US artificial-intelligence companies about the risks of the current pace of development, alongside calls for coordination and for slowing that pace. The executives issuing those warnings were not individually named.
• The macro squeeze: Two pressures hit alongside the AI warnings: bond yields rising above 5% and oil prices trading above $100. Higher yields reduce the present value of long-dated growth earnings, the core of the AI trade's valuation case.
• The July precedent: CNBC reported that a late-July selloff wiped more than $1tn from the market value of chip stocks, spanning Nvidia, SK Hynix, Samsung, Micron, AMD and TSMC. That episode set the template the current wave is repeating.
• The underlying fear: According to CNBC, the July decline ran on concern that AI infrastructure spending had peaked faster than expected — a demand-cycle argument rather than a technology one, which is why it hits suppliers across memory, foundry and accelerator segments at once.
• The breadth question: The named decliners cover US designers, a Japanese investment holding, Korean memory makers and Taiwan's foundry leader, indicating the repricing is running along the AI supply chain rather than within one national market.

Background

CNBC's late-July episode erased over $1tn from chip valuations on fears AI infrastructure spending had peaked early. The same names — Nvidia, AMD, Micron, TSMC, Samsung, SK Hynix — are again at the centre of the move.

Between the lines

The two supports that carried US equities for two years are weakening in the same week: the AI trade, now questioned by the industry's own executives, and cheap money, now priced out by yields above 5%. That combination matters because the July selloff turned on spending having peaked — a demand argument that higher financing costs make harder, not easier, to disprove.

What's next

Watch whether Nvidia's pre-market 3% decline holds into Tuesday's close, whether yields stay above 5% and oil above $100, and whether the named AI executives follow their warnings with any concrete coordination proposal.
