The AI Trade Is Being Repriced. A Rundown on Who Is Earning Their Valuation

An AI-driven sell-off erased about US$5 trillion in market value over three weeks, and the Nasdaq lost 5.2% in October. Alphabet had its worst day on record after its results, Intel fell nearly 29% in its worst day since 1974, and Marvell dropped 12.7% after announcing a mega-deal. [9, 10, 12]

The recent AI sell-off does not establish that a crash is coming. It does expose a tougher investment question: which companies can grow profitably—and how much are investors paying for that growth?

Here is how Nvidia, Broadcom, Alphabet, Meta, AMD, Marvell and Intel compare.

The numbers behind the story

Latest fully reported quarters, including AMD’s Q3 results released on 3 November. Ranked by our assessment on growth quality.

¹ GAAP operating expenses exclude cost of revenue and capital expenditure. Operating margin accounts for cost of revenue. Figures represent the whole company, not AI revenue alone; reporting periods differ. Sources: company releases; ratios calculated from reported figures. [1–4] ⁴ Meta’s figures include a US$9.89 billion legal charge; excluding it, operating expenses were 44% of revenue and operating margin 35.4%. Nvidia’s quarter ended 26 July 2026 and Broadcom’s on 2 August 2026. [13, 14, 17]

What is the market paying?

² As reported for 2 November 2026 by Stock Analysis; Nvidia, Broadcom and Meta from CompaniesMarketCap. AMD’s ratio uses its 2 November market value and Q3 revenue. ³ Market capitalisation divided by four times quarterly revenue: a simple scale comparison, not a trailing or forward price-to-sales ratio. It ignores debt, cash, seasonality and future growth; Marvell excludes the proposed Lumentum combination. [5, 15, 16, 18]

Our ranking for growth quality

1. Nvidia: the clearest case of profitable growth

Nvidia is the standout on both measures that matter here. Revenue more than doubled, up 106% to US$96.2 billion, and it kept US$66 of every US$100 of sales as operating profit. Operating expenses rose 55%, well below revenue growth.

Its market value is about 12.7 times annualised quarterly revenue, below AMD’s despite a far higher margin. The risk is concentration: its fortunes depend heavily on a small number of very large cloud customers continuing to spend. Management guided to about US$108 billion in revenue for the next quarter, roughly 12% above the last. [13]

2. Broadcom: custom AI chips, widening margins

Broadcom’s revenue rose 86% to US$29.6 billion, driven by AI semiconductor revenue of US$16.7 billion, up 221%. Remarkably, operating expenses fell 7% over the same period, lifting operating margin to about 54% from 37% a year earlier.

Broadcom designs the custom chips behind Google’s TPUs, and its guidance of about US$34.8 billion in revenue for the next quarter implies 93% growth. At about 13 times annualised revenue, the risk is reliance on a handful of very large customers whose spending plans can change. [17]

3. Alphabet: strongest foundation among the platform giants

Alphabet combines substantial scale with the highest operating margin among the platform giants. Revenue grew 25%, while operating income increased about 30%.

The concern is investment intensity. Quarterly capital expenditure of $51.4 billion exceeded operating cash flow of $42.3 billion, leaving negative free cash flow of $9.1 billion. A US$5.2 billion payment for a 2018 European Commission fine and a build-up of TPU inventory also weighed on cash generation. Its operating business looks strong; the returns on its infrastructure spending still need scrutiny. [1, 6, 11]

4. Meta: strong advertising, heavy spending

Meta grew revenue 26% to US$64.6 billion. Its reported operating margin fell to 20%, but that includes a one-off US$9.89 billion legal charge; excluding it, the margin was about 35%.

The bigger question is spending. Capital expenditure reached US$34.9 billion in the quarter and free cash flow turned negative, at –US$2.1 billion, with full-year capital spending guided to US$135–145 billion. At about 6.1 times annualised revenue, the market is already pricing in some of that doubt. [14]

5. AMD: growth accelerating, valuation still demanding

AMD’s third-quarter results, released after the US close on 3 November, beat expectations. Revenue rose 45% to a record US$13.4 billion, ahead of the roughly US$13.1 billion analysts expected, while operating expenses grew 25%. Operating margin improved to 21%, from 17% in the previous quarter, and data-centre revenue nearly doubled, up 97% to US$8.5 billion.

Management guided to about US$17 billion in revenue for the fourth quarter, implying about 66% year-on-year growth and well above analysts’ expectations of about US$16.2 billion. The shares rose more than 7% in after-hours trading. Growth is accelerating, but even before that rise AMD carried the richest valuation in this comparison, so it needs to keep delivering. [2, 7]

6. Marvell: healthy demand, greater execution risk

Marvell’s revenue increased 37%, with data-centre revenue up 46%. However, operating expenses increased approximately 38%, slightly faster than sales.

Its proposed all-stock Lumentum acquisition, which gives Lumentum an enterprise value of about US$115 billion, adds integration and shareholder-dilution risks. Marvell shareholders would own about 67% of the combined company, the deal is not expected to close until the first half of 2028, and Marvell’s shares fell 12.7% on the day it was announced. The opportunity is substantial; so is the need to demonstrate disciplined execution. [3, 8, 10]

7. Intel: improving results, less certain momentum

Intel grew revenue 21% while keeping operating expenses almost flat, lifting operating margin to 15.3%.

But its next-quarter revenue guidance of $15–16 billion implies a sequential decline from $16.5 billion and fell short of analysts’ expectations. Intel pointed to a slowing PC market, higher memory prices and an explosion at its factory in Israel, and its shares fell nearly 29% the next day. Its lower sales multiple should therefore be weighed against a less predictable recovery and its manufacturing investment requirements. [4, 12]

This is an editorial ranking of current growth quality and resilience, not a prediction of share-price performance.

Nvidia and Broadcom lead on both growth and profitability. Alphabet leads the platform giants on operating strength. Meta must show its spending pays off, AMD must grow into its valuation, Marvell must justify expansion costs, and Intel must sustain its recovery.

The lesson from the sell-off: look for revenue growing faster than expenses, profits converting into cash, and a valuation that leaves room for disappointment. Being in the AI supply chain alone answers none of those questions.
