Nasdaq Slides to Its Worst Day Since June as Chip Stocks Lose 7.2% in One Session

Wall Street Tumbles as Nasdaq Slides Faces a Major Selloff as AI Investment Fears Shake Investors

Wall Street witnessed a sharp selloff on Friday as growing concerns over artificial intelligence (AI) spending and disappointing corporate earnings triggered heavy selling across technology stocks. The Nasdaq Composite suffered its steepest single-day percentage decline since June 5, raising fresh questions about whether the AI-driven stock market rally can sustain its momentum.

The biggest concern for investors is no longer just how much technology companies are investing in AI, but whether those investments will generate enough revenue and profits to justify the enormous spending.

The Nasdaq Composite plunged 747.73 points, or 2.86%, to close at 25,437. Meanwhile, the S&P 500 declined 140.32 points, or 1.82%, to 7,580.07, while the Dow Jones Industrial Average fell 572.25 points, or 1.09%, to settle at 51,770.31.

Nasdaq Slides : Rising AI Spending and Debt Concerns Are Creating Fresh Market Pressure

The latest market correction reflects growing concerns about the enormous capital expenditure required to build AI infrastructure.

Meta Platforms, Alphabet and Amazon have indicated higher investments in AI infrastructure as competition for computing capacity intensifies.

Morgan Stanley expects AI infrastructure capital expenditure to exceed $1 trillion next year. JPMorgan estimates global AI-related capital spending could reach $5.5 trillion by 2030, including approximately $900 billion in 2026.

Financing these investments is becoming another concern. Meta’s proposed $97.5 billion fundraise has raised questions about shareholder dilution, while Microsoft is reportedly considering approximately $25 billion through its first US investment-grade bond sale in more than nine years.

Meanwhile, Meta, Amazon and Alphabet have collectively issued hundreds of billions of dollars in bonds over the past four years.

What happened on Wall Street on October 30?

The US stock market experienced a broad sell-off on Friday, October 30, 2026, after disappointing earnings-related developments from Intel and Amazon intensified concerns about the financial sustainability of the AI investment boom.

The Nasdaq suffered its steepest single-day percentage decline since June 5.

The sell-off was not limited to Friday. All three major US indexes also declined during the week.

• Nasdaq: down 2% for the week.

• S&P 500: down 0.6%.

• Dow Jones: down 0.9%.

Despite these losses, all four major indexes remained positive for 2026 through October 30. The S&P 500 was up 10.7%, the Dow 7.7%, Nasdaq 9.4% and Russell 2000 13.3%.

Big Tech Earnings Are Raising Questions About Future Growth

Investor concerns are also extending beyond AI infrastructure. According to Bloomberg, the advertising, consumer and retail businesses supporting major US technology companies are showing signs of slowing, even as their combined AI investment commitments approach $750 billion this year.

Alphabet’s latest results also raised concerns about search advertising growth and increasing cash expenditure. S&P Global Ratings has taken an initial step towards potentially downgrading Meta’s credit rating within the next two years, citing balance-sheet pressure from AI spending.

However, Microsoft and SpaceX have stood out, with results indicating that AI investments are beginning to generate business returns.

Intel’s 28.6% crash was about more than disappointing earnings

Intel −28.6% Friday share-price decline, as reported in the supplied market coverage

Intel became one of the biggest contributors to Friday’s technology sell-off.

However, an important detail missing from your article is the company’s disappointing forward guidance.

According to Reuters, Intel projected quarterly revenue more than $1 billion below market expectations and indicated that it did not expect positive cash flow during 2026.

This raised questions about whether Intel could finance its manufacturing expansion while simultaneously meeting growing demand for AI-related processors.

• Intel’s third-quarter PC chip business accounted for approximately half of its revenue.

• Rising memory prices were putting pressure on the PC market.

• Memory manufacturers were shifting production towards high-bandwidth memory used in AI systems.

• Intel faced the challenge of supplying enough processors for AI servers while dealing with weaker demand in its traditional PC business.

• Its cash and cash equivalents stood at $21.84 billion at September-end, against $46.32 billion in long-term debt.

Amazon’s results revealed a major contradiction in the AI investment story

Amazon AI spending concerns Third-quarter results released October 29

Amazon reported the following third-quarter 2026 results:

• Amazon expected approximately $220 billion in cash capital expenditure during 2026.

• The company reported a trailing 12-month free cash flow loss of approximately $42.4 billion.

• Amazon indicated that capital expenditure would remain higher as it expands AI infrastructure.

• Its fourth-quarter revenue guidance was $240 billion to $247 billion, compared with analysts’ expectations around $244.16 billion at the midpoint.

The market reaction was negative, with Amazon shares falling approximately 7% after hours following the earnings announcement.

The semiconductor sell-off spread across global technology stocks

The semiconductor index also recorded monthly losses exceeding 15%.

According to Reuters:

• ASML shares in Europe declined more than 6%.

• Taiwan Semiconductor Manufacturing Company (TSMC) fell nearly 2%.

• South Korea’s KOSPI declined approximately 3.5%.

• Samsung Electronics lost around 3%.

• China’s technology-focused STAR50 index fell to its lowest level in more than two months.

The pressure extended to the broader technology supply chain because rising memory prices were creating difficulties for PC and smartphone manufacturers.

Alphabet’s earnings exposed another major weakness in the AI investment story

Alphabet −12.6% Thursday’s share-price decline

Alphabet reported third-quarter results on October 28, 2026, which disappointed investors.

Alphabet’s advertising revenue missed estimates by approximately $1.4 billion, while its free cash flow turned negative as investment in AI infrastructure accelerated.

Google Cloud, however, remained a bright spot, with revenue more than doubling year-on-year to $30.71 billion.

The company also reported a cloud backlog of $561 billion, highlighting strong demand for its cloud services.

Meta’s $97.5 billion fundraising plan raised concerns about shareholder dilution

Meta Platforms $97.5 billion Planned equity offerings

The $97.5 billion figure refers to the combined planned equity offerings, not simply a single conventional share issue.

Reuters reported the following components:

• $25 billion in planned common-stock issuance.

• $12.5 billion in convertible preferred depositary shares.

• A separate programme to sell up to $60 billion in shares over time through an at-the-market offering.

The company was raising capital to finance its aggressive AI infrastructure expansion.

The concern is that issuing additional equity can dilute existing shareholders’ ownership if the new shares increase the outstanding share count.

Meta’s fundraising also highlighted a broader development: major technology companies are increasingly looking beyond their existing cash reserves to finance AI expansion.

Microsoft planned a $25 billion bond sale to finance its expansion

Microsoft $25 billion Reported planned US bond offering

Microsoft’s fundraising plans are another important development that deserves more explanation.

According to Reuters, Microsoft was planning its first US investment-grade bond sale in more than nine years.

The company was reportedly looking to raise approximately $25 billion.

The bond offering attracted more than $100 billion in orders, equivalent to more than four times the proposed issue size.

The reported structure included as many as 10 tranches, with maturities ranging from two to 40 years.

AI infrastructure spending could reach $5.5 trillion by 2030

JPMorgan’s research also highlighted that Amazon, Alphabet, Meta, Oracle and Microsoft could collectively spend approximately as much on AI capital expenditure in 2026 alone as they had spent cumulatively since ChatGPT’s launch in November 2022.

Energy Stocks Offer Some Support While Cryptocurrency Shares Decline

Energy stocks moved against the broader market weakness after Exxon Mobil and Chevron reported quarterly profits above expectations. Exxon gained 2.2%, while Chevron advanced 2.8%, supported by stronger refining margins.

Cryptocurrency-linked stocks remained under pressure following reports of a $6.3 billion theft from Binance. Coinbase, Strategy and Robinhood declined between 7.2% and 10.6%.

Market breadth also weakened significantly, with declining shares outnumbering advancing shares by 1.8 to 1 on the NYSE and approximately 3 to 1 on the Nasdaq.

Total US exchange trading volume reached 19.87 billion shares, above the 20-day average of 17.26 billion.
