Chip Stocks Fall as the Bond Rally Cheapens AI Spend

AI chip stocks led a 2.60% drop in the Nasdaq Composite on Thursday, October 22, after three overnight filings revived spending fears. Twenty-six chip and AI names accounted for 90% of the Nasdaq-100’s net loss in value. Most other large Nasdaq stocks held up or rose.

The same session sent investors into U.S. Treasuries and pushed the 10-year yield back through 5%, which lowers the cost of the data-center bills those filings just put on the table.

Twenty-Six Names Did Almost All of the Damage

The Nasdaq Composite closed at 26,008.86, down 694 points, its largest one-day fall since June 5, when it dropped 4.18%. The Nasdaq-100 lost 2.90%. Together its members were worth about $1.32 trillion less than at Wednesday’s close.

That loss was not a broad tech wipeout. The 22 makers of chips, chipmaking tools, and data-storage gear in the index lost about $726 billion, and every one of them fell. Meta Platforms, Microsoft, Amazon, and Alphabet, the four giants still building AI data centers, lost about $471 billion more. Those 26 companies made up 90% of the net decline and 78% of the gross losses among members that fell.

HOW THE NASDAQ-100 LOST $1.32 TRILLION

Nvidia, still the largest company in the index, accounted for about $235 billion of the chip group’s hit and fell more than 4%. Lam Research, which sells the machines that etch and deposit the layers on those chips, had the steepest percentage drop among the chip names, 11.76%. Meta fell 6.98%, Amazon 4.57%, Alphabet 3.15%, and Microsoft 2.23%.

The Philadelphia Semiconductor Index, the SOX, slid 6.7%. CoreWeave, the debt-heavy AI cloud operator, fell 10%. Oracle, which has borrowed to fund its cloud build, dropped about 3%.

The Composite closed 5.8% below its October 6 record of 27,599.89, and 11.9% above its last close of 2025. It was the 10th session of 2026 in which the index fell 2% or more.

Overnight Filings That Set Up Thursday

Chip buyers and chip-tool suppliers did not issue a joint warning. Two quarterly reports and one equipment maker’s call, all after Wednesday’s close, landed on the same nerve: how much the AI build will cost, and how it will be paid for.

THE THREE DOCUMENTS BEHIND THE TAPE

• Meta’s 10-Q: Leases not yet started and non-cancelable contracts rose to about $810 billion, and 2026 capital spending was narrowed to $135 billion to $145 billion.
• Tesla’s 10-Q: The 2026 spending floor was cut to in excess of $20 billion from in excess of $25 billion, even as the CFO said later-year bills will keep rising.
• Lam Research’s call: Record sales and a first-ever 40.2% non-GAAP operating margin came with a warning that supply bottlenecks would hold back December shipments.

Chip sellers can lose on either kind of news. A buyer whose signed bills keep growing raises the question of how long that pace lasts. A buyer that lowers this year’s floor raises questions about timing. A toolmaker that beats the quarter and still cannot ship everything it could sell tells you the constraint is parts, not orders.

Nvidia chief executive Jensen Huang said on Thursday that demand from neoclouds, the specialist AI cloud hosts, is “off the charts,” and that capital was scarce. The equity tape treated the scarce-capital line as the one that mattered.

Why the Bond Rally Makes the Spending Cheaper

Money leaving those names had to go somewhere. A large share of it went into Treasuries, which had offered little shelter on earlier tech slides this year.

TREASURY YIELDS, 4:05 P.M. EASTERN

• 10-year note: 4.972%, down more than 17 basis points, the first print below 5% since September 23, and the largest one-day decline since March 10, 2023.
• 2-year note: 4.659%, down more than 16 basis points.
• 30-year bond: 5.296%, down more than 14 basis points.

On October 7 the 10-year had traded as high as 5.36%, its highest intraday level since April 2002. Above 5%, the notes started to look like a place to hide again, even with inflation still a live worry and oil jumping on Middle East risk. Brent crude settled at $113.17 a barrel, up 4%. West Texas Intermediate closed at $99.47, up 2.39%.

Mitch Goldberg, president of ClientFirst Strategy, called it a flight to safety. “People are all of a sudden terrified of the amount of bond issuance by AI-related companies,” he said. Larry Holzenthaler, a senior portfolio manager for fixed income at Catalyst Funds, said Treasuries were “enjoying haven status” for the first time in a while, with weakness in tech, Middle East risk, and higher oil all in the mix.

That bid is the twist the spending-fear tape does not price. Lower Treasury yields feed into the cost of borrowing for the same data-center leases, utility interconnects, and chip contracts investors just marked down. The session punished the size of the AI bill, then made the bill cheaper to refinance.

Oil and stress in French government debt helped the haven bid too. The equity damage was still concentrated in AI. The S&P 500 fell 1.2%. The Dow Jones Industrial Average added 11 points. A majority of U.S. stocks rose.

Record Sales, Then an 11.76% Drop at Lam

Lam Research was the cleanest example of the day’s mismatch. The Fremont, California, toolmaker reported September-quarter revenue of $8.22 billion, up 54% from a year earlier and 22% from the June quarter. Non-GAAP diluted earnings were $2.20 a share. Non-GAAP operating margin reached 40.2%, the first time it had cleared 40%.

Our strategic investments in technology inflections and manufacturing capacity are paying off, strengthening our ability to outgrow the wafer fabrication equipment market as the industry expands.

Tim Archer, President and Chief Executive Officer, Lam Research earnings release

Guidance for the December quarter was $8.6 billion of revenue, plus or minus $400 million. Chief financial officer Doug Bettinger said that figure would have been a little higher without near-term supply-chain constraints, and that shipments delayed by timing should move into the March quarter. Management put 2026 wafer-fabrication equipment spending in the mid-$150 billion range and a preliminary 2027 outlook above $200 billion, led by DRAM, then advanced foundry logic and NAND.

China was 35% of September revenue, up from 26% in June, and is expected to fall as a share in December. That mix shift, plus a wide guide, gave traders a reason to sell a stock that had already run hard. The deeper read is less about China and more about what a bottleneck implies. If parts and clean-room space are the brake, the order book is not the problem.

Ken Griffin, chief executive of Citadel, said investors were “almost certainly in an AI bubble.” Bulls argue that indebted neoclouds are still small next to hyperscaler earnings power. Thursday’s buyers of Lam’s story were scarce either way.

Meta’s $810 Billion of Future Bills

Meta reported third-quarter results after Wednesday’s close and filed its 10-Q the same evening. Advertising sales grew 26%. Capital expenditures, including principal payments on finance leases, were $34.91 billion. Cash, cash equivalents, and marketable securities stood at $82.45 billion. Long-term debt was $80.922 billion, up from $58.744 billion at the end of 2025. The company also said it would create a new class of nonvoting Class C shares to help fund infrastructure.

The 10-Q’s commitments note is what the tape reacted to. Leases that have not yet started came to $355.73 billion of leases not yet started, covering data centers, energy-related infrastructure, colocations, and network gear, with terms running as long as 30 years. Non-cancelable contractual commitments were $454.52 billion, mostly third-party cloud capacity, servers, network kit, energy deals, and Reality Labs hardware. Added together, that is about $810 billion still to pay.

META’S SIGNED BILLS, TWO QUARTERS

Three months earlier the same two lines came to about $628 billion. Contracts due in 2027 alone rose to $121.41 billion, more than the $82.45 billion of cash and marketable securities on the balance sheet. None of that says Meta cannot pay. It does say the unpaid stack grew by about $182 billion in one quarter, and that 2026 spending was tightened to a range of $135 billion to $145 billion from $130 billion to $145 billion, a higher floor, not a lower ceiling.

Lorenzo Di Mattia, founder and chief investment officer at Sibilla Capital, put the investor error in one line.

The model developers have massive computing bills, while the infrastructure providers spend heavily on chips and data centers. Investors may be expecting the profits of the old software model while funding a spending race with no clear finish line.

Meta closed down 6.98%. Traders had first gone along with the Class C plan as a way to fund the build. By Thursday afternoon they were selling the build itself.

Homebuilders, Apple, and the Rest of the Tape

Forty-nine of the Nasdaq-100’s 100 companies rose. Once SpaceX is set aside, the remaining 73 members gained about $70 billion. Apple and Walmart added the most value of any member. SpaceX, listed in the index as aerospace even though its AI work now out-earns Starlink, fell 9.14% and lost about $198 billion, more than the other 74 companies combined.

That split is the session in miniature. The index is a handful of AI suppliers and spenders. The average stock was not in a panic. Homebuilders caught a bid as mortgage rates, which move with the 10-year, eased. Energy stocks had oil at their back. Utilities and other bond proxies firmed as yields dropped.

The Philadelphia Semiconductor Index had already fallen for eight straight sessions through October 16, shedding about 16% in that run, its longest losing streak since 2008. A bounce earlier in the week did not hold. LPL Financial’s research desk has the five largest U.S. cloud and AI infrastructure firms on track for combined capital spending above $600 billion in 2026. UBS has estimated that hyperscaler capex growth slows to 25% in 2027 and 6% in 2028 after a 76% jump this year to $673 billion. Supplier profits track the growth rate, not the level. A slower slope can hit chip earnings while the buildings are still going up.

Tokyo followed through on October 23, with selling again concentrated in AI and chip-related stocks after the SOX’s 6.7% slide. The U.S. close did not get revised overnight. The argument did not either.

Tesla Cut This Year and Left a Larger Tab

Tesla’s contribution was a quieter line in a 10-Q, not the shareholder letter. The filing now calls for capital spending in excess of $20 billion in 2026, driven by Super Intelligence work, including compute and data centers. The prior 10-Q had said in excess of $25 billion. Shares closed down 3.08%.

Spending through nine months was $13.01 billion, from $2.49 billion in the first quarter, $5.79 billion in the second, and $4.73 billion in the third. The third-quarter figure was well below the $7.5 billion average estimate compiled by LSEG, and free cash flow came in at $1.53 billion when many desks had penciled in a cash burn. On September 29 Tesla signed credit agreements with $30 billion of commitments. Chief financial officer Vaibhav Taneja said the company does not plan to draw on them this year.

We’re revising our CapEx guidance to be approximately $20 billion for the current year as a result of managing our capital deployment efficiently and plan to fund it primarily from our cash flows from operations.

Vaibhav Taneja, Chief Financial Officer, Tesla Q3 2026 earnings call

He also said spending will keep expanding over the next few years as Tesla adds robotaxi fleet, Optimus capacity, solar manufacturing, more SI compute, and a semiconductor fab. The 2026 cut is a timing shift. The later bill got larger in the same breath.

That is the session’s leftover. Demand for the chips is still, in Huang’s word, off the charts. Lam could not ship all of it. Meta’s unpaid stack grew by about $182 billion in a quarter. Tesla postponed some of this year’s checks and described a bigger slate after that. Investors sold the suppliers, bought the Treasuries, and left the 10-year at 4.972%. Cheaper money does not settle whether those data centers earn their keep. It does make the next dollar of spend less painful to fund.
