Key Highlights

● Intel's fourth-quarter Revenue guide fell well short of the $17.07 billion consensus.

● AMD fell 8.72% and Arm 9.41% in pre-market trading on Friday.

● AMD reports Nov. 3 and Arm Nov. 4, with Qualcomm and Palantir later that week.

● Investors are weighing whether AI faces a Demand problem or a spending problem.

Chip stocks are entering next week's Earnings run on the back foot. Intel (NASDAQ:INTC)'s weak fourth-quarter outlook knocked about 25% off its shares before Friday's open and dragged most of the sector lower. Next week, AMD (NASDAQ:AMD), Qualcomm (NASDAQ:QCOM), Arm (NASDAQ:ARM) and Palantir (NASDAQ:PLTR) all report, giving investors a fresh read on whether the AI trade has a demand problem or just a spending problem.

The sector heading in

As of 8:23 a.m. ET Friday, pre-market data showed AMD at $517.00, down 8.72%, and Arm at $207.24, down 9.41%. According to media reports, AMD, Arm, Qualcomm, Nvidia (NASDAQ:NVDA), Broadcom (NASDAQ:AVGO) and Micron (NASDAQ:MU) were among chipmakers down between 2% and 9%. Overseas, SK hynix fell 8.3% and Samsung 5.9% in Seoul, while ASML (NASDAQ:ASML) dropped about 5% in Amsterdam.

The catalyst was Intel. Its fourth-quarter revenue guide of $15 billion to $16 billion fell well short of the $17.07 billion consensus. Its data-center sales grew 78% in the third quarter, but it expects PC chip sales to fall more than 20% sequentially as rising memory prices hurt PC demand. Intel CFO David Zinsner said he sees that slowdown continuing "at least through the first half of next year."

What each report will test

AMD reports on Nov. 3, according to automated market notes. It's the most direct AI read, since it competes with Nvidia in data-center accelerators and with Intel in PC and server processors. The same notes say AMD had rallied about 170% this year, which raises the bar, though that figure couldn't be independently confirmed. Meta (NASDAQ:META) disclosed that Nvidia, AMD and Broadcom expressed nonbinding interest in buying up to $5 billion of its recent common stock offering, a sign of how closely chipmakers are now tied to their customers' financing.

Arm reports on Nov. 4, per the same notes, which also flag uncertainty over its litigation with Qualcomm. Its Royalty model makes it sensitive both to smartphone and PC volumes and to AI data-center designs. Qualcomm's report will show how memory costs are affecting handset demand. Exact dates for Qualcomm and Palantir weren't confirmed, beyond a media report's note that both report during the week.

Sandisk (NASDAQ:SNDK) offers a warning about expectations. It beat its own guidance with revenue of $11.03 billion and guided higher, yet fell about 8% pre-market on concerns that memory pricing may be nearing a peak, according to media reports.

Palantir is the software test. After Twilio (NYSE:TWLO) fell about 20% despite a beat, and Fortinet (NASDAQ:FTNT) dropped 20.1% on Thursday, investors will scrutinize whether AI software demand is accelerating enough to justify premium valuations.

The bigger debate

The question running through every report is whether AI spending will continue at this pace. Amazon (NASDAQ:AMZN) reaffirmed $220 billion of 2026 capex and Alphabet (NASDAQ:GOOGL) guided to $195 billion to $205 billion, which supports chip demand, even as investors punish the spenders for cash burn. "Strong AI demand is no longer enough on its own," one analyst said.

Macro risks add to the uncertainty. Tuesday's midterm elections could shift the outlook, and one market strategist said a Democratic "blue wave" would be "negative for both the AI names." Section 232 tariffs of 25% apply to certain advanced chips, including Nvidia's H200 and AMD's MI325X, according to a Tariff tracker updated Oct. 27.

What to watch: data-center revenue growth and guidance at AMD, handset and PC commentary at Qualcomm and Arm, and Palantir's commercial growth rate. With the Nasdaq-100 already headed for a losing October, a strong set of numbers could spark a rebound, while further guidance cuts would deepen the selloff.
