US technology stocks suffered a fresh wave of heavy selling on Friday. The latest earnings results and outlooks from Intel (ASX: INTC) and Amazon (ASX: AMZN) intensified market worries about the returns on massive AI investments, and the tech selloff spread from individual names to the entire semiconductor sector. Intel (ASX: INTC) plunged more than 30% intraday, a record drop, while the Philadelphia Semiconductor Index tumbled more than 9% at one point and closed down over 7%.
At midday US Eastern time on the 30th, when stocks refreshed their lows of the day, the Nasdaq was down more than 3.8%, the Nasdaq 100 fell over 4%, the S&P 500 dropped about 2.5%, and the S&P 500 information technology sector slid 5.5%. Intel (ASX: INTC), Google parent Alphabet (ASX: GOOGL) and Meta (ASX: META) all briefly fell below their issue prices during the session. By the close, the Nasdaq 100 was down nearly 3.5%, and the combined market value of its constituents evaporated by more than $1 trillion in a single day.
The selloff is no longer merely a reaction to individual companies missing earnings expectations. With total AI spending by US tech giants expected to reach $750 billion this year, investors are scrutinizing capital expenditure, cash flow and core business growth far more strictly. At the same time, recent large-scale share offerings by companies such as Intel (ASX: INTC), Alphabet (ASX: GOOGL) and Meta (ASX: META) have also been hit by falling share prices, and whether the AI investment boom can continue and when the huge outlays will pay off has become the market's central focus.
Chip Stocks Sold Off Across the Board, With AMD and Others Down More Than 10% Intraday
Near midday US Eastern time on Friday, technology stocks became the main drag on the broader US market. By the close, the Nasdaq was down nearly 2.9% and the S&P fell more than 1.8%, both posting their biggest daily declines since June 5, while the S&P 500 information technology sector dropped more than 4%. The Philadelphia Semiconductor Index (SOX) narrowed its loss to within 8% by the close, still marking its worst single-day performance in more than a year.
Chip stocks fell almost across the board. Intel (ASX: INTC) hit a session low with an intraday drop of about 31.4%, and based on a closing decline of nearly 29%, it marked its biggest drop since July 1974. By the close, SanDisk (ASX: SNDK), AMD (ASX: AMD) and Qualcomm (ASX: QCOM) were all down more than 10%, while SK Hynix (ASX: SKHY), which had fallen more than 10% at midday, closed down nearly 8%. Broadcom (ASX: AVGO) and Micron (ASX: MU) each fell more than 5%, TSMC (ASX: TSM) slid nearly 6%, and Nvidia (ASX: NVDA) dropped more than 4%.
The plunge in Intel (ASX: INTC) was especially striking. The company's first-quarter revenue and second-quarter guidance, released after the bell on Thursday, both came in above analyst expectations, yet investors remained concerned about its business recovery prospects. The company had previously warned that supply chain issues were limiting its ability to deliver data center-related products, and that weakness in the PC market could persist into the first half of 2027.
Intel (ASX: INTC) also expects to be unable to achieve positive free cash flow this year. For a company striving to rebuild its manufacturing capabilities and win share in data center chips, the combination of capacity bottlenecks, weak demand in its legacy businesses and heavy cash burn has prompted the market to reassess the pace of its transformation.
More notably, Intel (ASX: INTC) had already racked up enormous gains. Media outlets noted that, as of before Thursday's earnings release, the stock had risen about 150% year to date, partly benefiting from growing CPU demand, as CPUs are becoming an important component for running agentic AI workloads.
However, D.A. Davidson downgraded Intel (ASX: INTC) to "neutral" from "buy" on Friday, titling its report "Not fixed yet" and pointing directly to the company's unresolved operating problems.
The analyst wrote: "We understand that the PC market is being affected by industry-wide factors. But when the weakness is this pronounced, it is hard to justify the current valuation level."
That assessment highlights the key contradiction behind the slump in Intel (ASX: INTC) shares: AI demand can drive growth in the CPU market, but that does not mean the company can immediately resolve its production and supply chain problems, nor does it mean the previously sharp share price gain remains justified.
Intel's troubles are also weighing on the entire semiconductor sector. Even as AI infrastructure buildout continues, investors are beginning to distinguish between growth in industry demand and a company's actual ability to deliver results. For chip stocks that had previously posted large gains, any doubt about guidance, supply capability or valuation can quickly amplify a price correction.
Amazon Maintains $220 Billion Capital Spending Guidance for the Year, Cash Flow Pressure Back in Focus
Amazon (ASX: AMZN) also came under pressure. After reporting third-quarter results after the bell on Thursday, its shares fell about 7% in premarket trading and continued to decline after Friday's open, dropping nearly 6% early on, though the loss gradually narrowed and the stock closed down about 1.4%.
Amazon's third-quarter net sales rose 12% year over year to $201.94 billion, below market expectations, while diluted earnings per share of $1.89 also fell short of analyst estimates. Although operating profit reached $28.1 billion and the operating margin rose to 13.9%, a record high, the strong profitability still failed to fully offset concerns about growth quality and capital deployment.
The cloud business was the bright spot in the report. Amazon Web Services (ASX: AWS) third-quarter sales rose 39.3% year over year to $46 billion, the fastest growth in nearly five years, with an annualized revenue run rate of $184 billion.
However, Amazon maintained its expectation of roughly $220 billion in cash capital expenditure for 2026. Its free cash flow over the past 12 months swung to a net outflow of $42.4 billion, compared with a net inflow of $14.8 billion a year earlier, while net capital expenditure rose by $94.8 billion year over year, mainly reflecting increased AI investment.
In other words, Amazon's cloud business is growing rapidly, but the infrastructure investment needed to support future growth is also rising quickly. The market needs to judge whether AWS revenue and profit growth can continue to cover the enormous outlays on data centers, chips and other infrastructure.
Bloomberg previously noted that total AI spending by US tech giants is expected to reach $750 billion this year. At the same time, growth in core businesses such as advertising and e-commerce at companies including Alphabet (ASX: GOOGL) and Amazon is showing signs of slowing, making investors even more focused on how much incremental revenue AI investment can actually generate.
The market's concern is not that tech giants entirely lack growth opportunities, but whether the huge investments can deliver returns sufficient to justify current valuations. When capital expenditure keeps climbing, free cash flow comes under pressure and traditional business growth slows, simply emphasizing strong AI demand is no longer enough to satisfy investors.
Amazon's performance is a microcosm of this contradiction: AWS continues to grow strongly and overall profitability has improved, yet investors are still asking when ever-expanding AI spending will translate into more substantial free cash flow.
From Alphabet to Amazon, AI Investment Returns Become the Focus of Earnings Season
Friday's selloff was not an isolated event but a continuation of the market repricing triggered by this week's earnings from large technology companies.
After Alphabet (ASX: GOOGL) reported earnings on Wednesday, its shares plunged about 13% on Thursday, one of the largest single-day declines in the company's history, wiping out nearly $500 billion in market value. Investors were worried both about slowing growth in Google's search advertising business and about the pressure on free cash flow as the company maintains high AI capital spending.
The subsequent results and outlooks from Amazon (ASX: AMZN) and Intel (ASX: INTC) further intensified those concerns. Meanwhile, Meta (ASX: META) had previously said it would continue investing heavily in AI, and its next-generation agent product Muse is also seen as requiring substantial computing power. Large technology companies are continuously expanding AI infrastructure investment, but the speed at which those investments pay off remains uncertain.
This means the market's criteria for evaluating the AI trade are changing. Previously, investors focused mainly on whether companies could secure more computing power, expand data center scale and sustain rapid growth in AI businesses; now, the scale of capital expenditure, financing methods, cash flow changes and investment payback periods are becoming equally important considerations.
Jake Behan, head of capital markets at Direxion, commented:
"This is a great example of how the AI trade has changed. The market is no longer just asking how fast you can grow, but how much you need to spend to achieve that growth."
This shift is especially important for large technology companies. Building AI infrastructure requires sustained funding, and companies must not only buy chips and build data centers but also bear power, networking and operating costs. Even if end demand is strong, the investment payback period may be longer than the market previously expected.
Bloomberg reported that tech giants are raising funds for AI infrastructure through bond issuance, share sales and multibillion-dollar data center agreements, while also taking on enormous future spending obligations. As a result, investors are paying closer attention to whether these outlays will squeeze cash flow and whether new AI products can create enough commercial value.
For the market, the real question has shifted from "Will AI grow?" to "Can AI growth generate economic returns commensurate with the investment?"
Tech Giants Diverge, Nvidia Becomes a Relative Laggard Among the Mag 7
The "Magnificent Seven" (Mag 7) showed divergent intraday moves on Friday.
As of near midday, Nvidia (ASX: NVDA) was the biggest decliner among the seven and the only one whose losses continued to widen. Amazon (ASX: AMZN) fell nearly 6% early on before paring most of the loss, while Alphabet (ASX: GOOGL) dropped nearly 2% in early trading and closed down less than 1.5%.
Meta (ASX: META) fell more than 2% early on, then briefly turned lower several times, closing down more than 1.5%. Microsoft (ASX: MSFT) slid nearly 3% early on and closed down nearly 1.6%. Apple (ASX: AAPL) briefly turned positive during the session and closed down 1.2%.
This shows that while the market is broadly reducing risk exposure to technology stocks, investors are not selling all large technology companies with the same intensity. Some stocks attracted buying after early declines, indicating that funds are still differentiating among companies based on business performance, cash flow conditions and valuation levels.
Still, narrowing losses in individual names does not mean AI investment worries have faded. As large technology companies report earnings one after another, investors' tolerance for high valuations and heavy capital expenditure is declining, and any results or guidance that falls short of expectations could trigger sharper price adjustments.
"Not a Reckoning," but Crowded Positioning and Valuation Pressure Are Emerging
Despite the sharp technology selloff, some market participants believe it does not mean the growth logic of the AI industry has been completely overturned.
Matt Orton, chief market strategist at Raymond James, said in a CNBC interview on Friday:
"I don't think this is a reckoning, but I do think investors should seriously consider one question: despite still-strong fundamentals, positioning across the sector remains highly crowded."
That assessment reveals another risk in the current market. Over the past year, the AI investment boom has driven sharp gains in chip stocks and related technology companies, concentrating large amounts of capital in a handful of popular names. When earnings and guidance fail to keep delivering positive surprises, crowded positioning can amplify selling pressure from profit-taking and risk control, even if fundamentals have not fundamentally reversed.
Alphabet's (ASX: GOOGL) earlier earnings already showed slowing growth in core businesses such as search advertising, and the market immediately questioned its heavy capital spending. Amazon's (ASX: AMZN) latest results also exposed pressure on growth in its traditional e-commerce and advertising businesses, while Intel (ASX: INTC) was dragged down by PC demand and supply chain problems.
These problems are not identical, yet they point at the same time to the market's core concern: how much incremental profit and cash flow can companies actually generate from the huge sums they are investing in AI?
Tech giants still have powerful cloud computing, advertising, consumer and enterprise software businesses, and AI may open new revenue sources in the future. But when capital expenditure grows faster than cash flow improves, the market's patience with investment returns can quickly wear thin.
Therefore, Friday's technology stock slump looks more like a concentrated repricing of valuations, positioning and investment return expectations than a single signal proving that AI demand has reversed.
Earnings Margin for Error Narrows, Market Begins Punishing Growth Misses
Bloomberg reported that investors are reacting more harshly to companies missing expectations. This is especially true in the technology and communication services sectors, where post-earnings share price adjustments have widened noticeably.
With about one-third of earnings season completed, S&P 500 companies' profit growth has slowed to about 26% from about 32% in the second quarter. Bloomberg Intelligence expects third-quarter earnings growth in the technology sector to slow to 65% from nearly 77% in the previous quarter, while communication services may slow to 3.2% from nearly 10%.
Although these growth rates remain historically high, for technology and communication services companies that carry large weight in the US stock market, slower growth means the market may no longer be willing to grant them the same valuation premium as before.
Chris Zaccarelli, chief investment officer at Northlight Asset Management, said that in the current environment, investors are reacting "much more sensitively than usual," preferring to sell first and look for explanations later rather than passively absorb losses after further declines.
He also noted that if earnings in a certain area fall short of expectations, that area can quickly face repricing as well.
This logic was especially evident in this week's technology stock trading: after Alphabet's (ASX: GOOGL) earnings triggered a sharp decline, results from Amazon (ASX: AMZN) and Intel (ASX: INTC) brought doubts about AI spending, traditional business growth and cash flow to a head, with the shock spreading from individual stocks to the entire semiconductor sector.
Still, peaking earnings growth does not necessarily mean the US stock bull market is over. Bloomberg Intelligence expects S&P 500 profit growth to remain close to 20% in 2027 and the first quarter of 2028. What the market needs to judge next is the extent of the slowdown in earnings growth and whether companies can continue to meet expectations amid high interest rates, tariff pressure and elevated energy costs.
For the AI industry, long-term demand prospects and short-term share price performance are not contradictory. AI may still drive growth in cloud computing, data centers and chip demand, but as investment scale keeps expanding and corporate cash flow comes under strain, capital markets will demand a clearer path to returns.
Friday's technology selloff reflects exactly this change: investors are not simply rejecting AI, but reassessing the price they are paying for it and how much value this unprecedented infrastructure race can ultimately create for shareholders.
