Key Highlights

● Applied Materials fell sharply on Friday, October 30, 2026.

● Lam Research and ASML also fell steeply.

Applied Materials (NASDAQ:AMAT) fell sharply on Friday, October 30, 2026, as chip-equipment stocks sold off on doubts about AI capital spending. The Santa Clara, California-based company had no company-specific news; it moved with its sector. Reports differed on the size of the move.

Applied Materials makes the machines that chipmakers use to deposit, etch and inspect the layers that form semiconductors. Its sales depend on how much foundries and memory makers invest in new factories and equipment, which in turn depends on Demand from the companies building AI data centers.

That chain of dependence put the stock in the line of fire on Friday. Lam Research (NASDAQ:LRCX) and ASML Holding (NASDAQ:ASML) also fell steeply.

The capex question

The doubts came from several directions. Alphabet (NASDAQ:GOOGL) reported capital spending of $51.4 billion for the quarter, up $6.5 billion from the prior quarter, alongside negative free Cash Flow of $9.1 billion. Its shares suffered a record drop on Thursday and slipped again on Friday.

Amazon (NASDAQ:AMZN) then reported trailing 12-month free cash flow of negative $42.4 billion, compared with positive $14.8 billion a year earlier. The company held its 2026 capital spending plan at about $220 billion and signaled another increase next year. "On the CapEx involved to grow the way we're talking about, it's meaningful," Chief Executive Andy Jassy said

A market analyst said that "Together, Amazon, Google, Microsoft (NASDAQ:MSFT) and Meta (NASDAQ:META) spent more than $200bn in the third quarter alone," and that "the risk is that higher financing costs will absorb more of the cash generated,"

Microsoft, by contrast, beat expectations for its Azure cloud Business and raised $25 billion in a Debt sale. Its shares still retreated on Friday, according to market data, as megacap technology stocks moved lower.

Intel lights the fuse

Intel (NASDAQ:INTC)'s warning added to the pressure. The chipmaker forecast fourth-quarter Revenue of $15 billion to $16 billion, well below expectations, and warned of cash burn, citing a weak PC market, Manufacturing hurdles and heavy production spending. Its shares suffered what market reports called their steepest one-day drop on record.

The Philadelphia Semiconductor index fell steeply to 10,688.80. Advanced Micro Devices (NASDAQ:AMD), Qualcomm (NASDAQ:QCOM), Nvidia (NASDAQ:NVDA), Broadcom (NASDAQ:AVGO) and Micron (NASDAQ:MU) all slid.

The broader market posted its worst session since June. The S&P 500 fell 140.32 points to 7,580.07, the Dow Jones Industrial Average lost 572.25 points to 51,770.31 and the Nasdaq Composite tumbled 747.73 points to 25,437.00, its worst day since June 5. The Russell 2000 dropped 47.37 points to 2,811.84.

A senior market analyst said: "The message from investors is becoming clearer: strong AI demand is no longer enough on its own."

Elsewhere, oil rose above $100 a barrel, crypto stocks fell after Binance was reportedly hacked for about $6.3 billion, and markets now expect the Federal Reserve to raise rates in December after it left its benchmark rate range unchanged on Wednesday.

What to watch

Investors will look for any change in spending plans from the large cloud companies and chipmakers, since their budgets drive demand for Applied Materials' equipment. Commentary from customers on factory Investment will be closely watched.

The coming week brings Apple (NASDAQ:AAPL)'s results on Monday, November 2, Qualcomm's on Wednesday, November 4, and the October jobs report on Friday, November 6. The midterm elections on Tuesday, November 3, could also matter, as investors watch races for data-center implications.
