Cloud Cash Burn and Memory Costs Squeeze PCs and Software

The week in one line — The week ended October 30 exposed the financial and physical cost of the artificial intelligence build-out, as the largest cloud platforms burned through their own cash and tapped external capital while high memory prices and tight IT budgets starved the personal computer market. Even where cloud revenue accelerated, investors punished companies whose spending outran their free cash flow or whose traditional businesses showed strain. The bill for data-centre expansion is now arriving in credit markets and legacy hardware lines alike.

The thread

For two years, the major technology platforms paid for their data-centre build-out from the cash generated by their core businesses. This week proved that internal cash flow is no longer enough (per CNBC Technology). As we covered in Tuesday's brief, Meta ($META) turned to equity markets with a $95 billion stock offering alongside Anthropic's initial public offering prospectus, and by Friday S&P Global Ratings had revised its credit outlook on Meta to negative over rising capital spending and negative free cash flow. Amazon ($AMZN) reinforced the strain in Friday's brief, posting $42.4 billion in negative free cash flow even as AWS revenue grew 39% on new deals with Meta and OpenAI (per CNBC Technology). Chief executive Andy Jassy held 2026 capital spending plans unchanged while promising to keep spending to build a $1 trillion cloud business (per TechCrunch AI).

Smaller builders face an even tighter credit market. Blackstone predicted Anthropic will receive a high-yield junk rating from credit agencies after its listing, raising its borrowing costs (per TechCrunch), while Nvidia ($NVDA) is weighing acting as a cosigner on a data-centre loan for specialised cloud provider Nscale in West Virginia as lenders grow cautious (per TechCrunch). As measured by our signals dashboard, hyperscaler capital expenditure is running 100.5% above last year, a saturation phase that acts as a headwind for equities while high-yield credit spreads have widened by 14 basis points over the past month to 326 basis points. The build-out is now leaning heavily on external financing.

That capital drain is actively cannibalising other corporate budgets. When OpenAI chief executive Sam Altman remarked on Friday that it is better for memory chips to sit in data centres than in desktop computers (per The Verge), Intel ($INTC) shareholders were already living the consequence. Intel fell 28.6% on Friday, wiping out $140 billion in market value after blaming weak guidance on a PC slowdown and struggles to make enough server chips (per CNBC Technology, MarketWatch). Rising memory prices are denting PC demand while corporate technology teams have less budget left for laptops (per MarketWatch), a slump that also showed up in declining PC revenue at Microsoft ($MSFT) (per Ars Technica). Even within the cloud giants, the revenue side is uneven: as noted in Thursday's brief, Microsoft generated $10 billion in quarterly revenue from its commercial arrangements with OpenAI as Azure reached $33.2 billion, yet Alphabet ($GOOGL) dropped 12.6% on Thursday on concerns that artificial intelligence is impairing search monetisation despite its cloud revenue doubling. Meanwhile, ServiceNow ($NOW) fell 27.0% on Thursday after cutting its outlook for growth in remaining performance obligations, the contracted backlog of future revenue not yet recognised.

The one area where demand shows no sign of slowing is the physical electrical grid. In Wednesday's brief, the US Department of Energy offered Constellation Energy ($CEG) a conditional loan commitment of up to $5 billion to finance 1.1 gigawatts of nuclear uprates across eight plants. Utilities spent the rest of the week raising their load forecasts: American Electric Power expanded its investment plan to $100 billion with 84 gigawatts of contracted large loads, FirstEnergy's data-centre pipeline reached 26 gigawatts, and Hubbell reported that data-centre purchases of electrical equipment have risen 80% since 2025 (per Utility Dive). To capture that transmission spending as gas turbine orders slow, GE Vernova ($GEV) agreed on Thursday to buy high-voltage equipment maker Trench Group for $9 billion (per Utility Dive). Grid equipment remains the tightest bottleneck.

Who moved

Nine of our tracked companies appeared on the daily boards twice during the week, and the sharpest repeat moves belonged to enterprise software and cybersecurity. ServiceNow slipped 3.0% on Wednesday before its 27.0% drop on Thursday following its cut to backlog guidance. Fortinet ($FTNT) mirrored that two-day slide, falling 5.9% on Wednesday and 20.1% on Thursday, while Datadog ($DDOG) dropped 11.5% on Friday; nothing in the week's filings or coverage explains the moves in Fortinet or Datadog. Older software names fared better by Friday, with Adobe ($ADBE) falling 4.0% on Tuesday before edging up 0.9% on Friday, and Intuit ($INTU) dropping 3.4% on Tuesday before gaining 3.0% on Friday.

Hardware and supply-chain names whipsawed between days. Sandisk ($SNDK) rose 7.7% on Wednesday as memory tightness stayed in focus, then gave it all back with a 13.5% drop on Friday. USA Rare Earth ($USAR) fell 4.5% on Monday before jumping 16.7% on Tuesday alongside federal supply-chain loans, while Nebius ($NBIS) slipped 3.5% on Monday and gained 11.2% on Tuesday. Single-session shocks rounded out the board: Vertiv ($VRT) rose 16.5% on Wednesday, Marvell Technology ($MRVL) fell 13.2% on Thursday, and Coherent ($COHR) dropped 11.3% on Friday alongside Intel's 28.6% fall.

Every major equity benchmark closed on its weekly low. The S&P 500 ETF ($SPY) fell 0.6% to 755.72 after trading as high as 772.31, while the Nasdaq Composite dropped 2.0% to 25,437.00 from a high of 26,549.85 and the Nasdaq 100 ETF ($QQQ) lost 2.0% to 690.49. The Technology Sector ETF ($XLK) fell 2.0% to 179.51, the Semiconductor ETF ($SMH) slipped 0.9% to 522.49 after reaching 567.67 mid-week, and the Software ETF ($IGV) took the heaviest damage, falling 5.7% to 104.29 from a high of 111.91. The 10-year Treasury yield fell six basis points to 4.93%, and $VIX ended down 0.2% at 19.42.

What changed

The week's evidence tilted our AI Compute Build-out and AI Platforms & Cloud themes against the bulls. Both themes are now challenged by direct proof that capital spending is outgrowing the cloud giants' internal cash flows and outrunning near-term returns outside of core cloud rental. When Amazon posts a $42.4 billion free cash flow deficit, Meta takes a negative credit outlook from S&P Global Ratings after a $95 billion equity raise, and Nvidia considers cosigning customer debt, the self-funded phase of the cycle is over. Within our compute universe, median valuations sit at the 84th percentile of their own history with only 1 of 18 companies in a rising price trend, leaving only Credo Technology ($CRDO) cheap against its own past in an adverse context.

In AI Software & Agents, our broader theme readings still show support following OpenAI's Tuesday release of GPT-6.1 Terra, an agentic model priced roughly 50% below its predecessor. Yet the market's reaction to ServiceNow's Thursday guidance cut and the 5.7% drop in the software ETF complicate last week's narrative that capital would cleanly rotate into application vendors. ServiceNow, Salesforce ($CRM) and Adobe all screen as cheap against their own past in our universe, with Salesforce in a supportive context and ServiceNow in a mixed one, but enterprise budget scrutiny is clearly testing backlog growth. By contrast, our AI Power & Critical Minerals theme saw its thesis confirmed across multiple sessions as utilities locked in gigawatts of load and federal nuclear loans advanced.

The week ahead

Eighteen of our tracked companies are scheduled to report results next week, providing a direct test of all three threads.

• PC and server chip demand: Apple ($AAPL) is expected to report on Monday, November 2, followed on Tuesday, November 3 by Advanced Micro Devices ($AMD), Super Micro Computer ($SMCI), Arista Networks ($ANET) and Astera Labs ($ALAB), with Qualcomm ($QCOM) and Coherent due on Wednesday, November 4 and Lumentum ($LITE) on Thursday, November 5. After Intel blamed its guide on PC weakness, high memory prices and AI server chip supply constraints (per MarketWatch), AMD's results will show whether Intel's struggles are industry-wide or company-specific.
• Enterprise software budgets: Palantir ($PLTR) is scheduled to report on Monday, Datadog before the open on Wednesday, and Cloudflare ($NET) on Thursday. Their customer expansion and backlog figures will test whether ServiceNow's slowdown is isolated or if corporate IT teams are freezing software spend alongside laptops. Meanwhile, Okta is slated to join the S&P 500 on Wednesday (per MarketWatch).
• Power, minerals and factory automation: Energy Fuels ($UUUU) is due on Wednesday, USA Rare Earth on an estimated Thursday date, and Vistra ($VST) before Friday's open, testing whether utility load pipelines are translating into generation and mineral contracts. In robotics, Aeva Technologies ($AEVA) and Cognex ($CGNX) are expected on Wednesday, followed by Rockwell Automation ($ROK) before Thursday's open.
