Cloud Capex Lags and Search Doubts Test AI Hardware and Platforms

Microsoft capex delays and Alphabet search slowing test AI hardware and cloud themes after the close, even as Vertiv and memory makers surge.

Market data from the close — the last completed trading session before publication.

The setup — After Wednesday's close, quarterly reports from Microsoft ($MSFT) and Alphabet ($GOOGL) split the evidence on the AI build-out. While Azure revenue jumped 48% (per CNBC) and Alphabet's cloud revenue doubled (per MarketWatch), slower core search growth at Google and lower-than-expected quarterly capital spending at Microsoft strained the case that hyperscaler budgets and AI returns will rise without interruption.

What changed for the themes

Our AI compute build-out theme lost support after Wednesday's close as hyperscaler spending and return figures pulled in opposite directions. On the narrative that the largest AI buyers are still raising their capital budgets, Alphabet held its 2026 capital spending guidance unchanged while projecting a significant increase for 2027 (per CNBC), and Microsoft's quarterly capital spending and finance leases of $45.2 billion came in below analyst estimates because third-party capacity deliveries were delayed (per Stocktwits). Earlier during Wednesday's session, Google altered its cloud strategy by enlisting partners to sell its custom TPU chips beyond its own cloud (per CNBC). Overseas memory results after the close backed the supply bottleneck thesis, as SK Hynix and Samsung Electronics both reported record third-quarter profits (per CNBC and CNBC). Even so, the narrative that AI spending is outrunning its returns challenged the theme after Alphabet missed quarterly revenue and earnings expectations (per CNBC).

Our AI platforms and cloud theme remains contested following the post-close earnings releases. Microsoft grew total revenue 19% to $92.3 billion and net income 32% to $33.6 billion (per The Verge), recording $10 billion in quarterly revenue from its commercial arrangements with OpenAI (per TechCrunch) as Azure revenue reached $33.2 billion. Coupled with Oracle ($ORCL) stating on Wednesday that it will cap additional fundraising at $20 billion through fiscal 2030 alongside a $225 billion revenue forecast, those figures supported the theme on the narrative that the build-out is outgrowing cloud cash flows. Yet Alphabet challenged the theme on the returns narrative: despite total revenue rising 25% to $127.6 billion (per TechCrunch) and cloud revenue doubling, search ad growth slowed to 12% and free cash flow turned negative at $9.07 billion (per Investing.com), sending the shares down 10% in premarket trading (per CNBC).

Our AI software and agents theme met a post-close setback at one of its core companies despite gaining support in our overall readings. During Wednesday's session, Anthropic launched tools to show enterprise customers what their AI spending is buying ahead of its planned IPO (per TechCrunch). After the close, however, ServiceNow ($NOW) — which our readings flag as cheap against its own past alongside Salesforce ($CRM) and Adobe ($ADBE) — fell nearly 18% in Thursday premarket trading as investors digested its third-quarter results (per MarketWatch). Separately after the close, cloud security startup Upwind raised $400 million at a $3.8 billion valuation after walking away from an acquisition offer from Datadog ($DDOG) (per TechCrunch).

Nothing new altered our readings on our AI power and critical minerals theme — beyond the $5 billion federal nuclear loan commitment to Constellation Energy ($CEG) (per TechCrunch) that we covered in yesterday's brief — or on our robotics and physical AI theme.

Risks to watch

The sharpest risk working against both compute and platform themes is that AI investment outruns the revenue it brings in. Alphabet's third-quarter miss gave that risk concrete evidence: Google advertising revenue of $82.01 billion missed expectations by roughly $1.4 billion as search ad growth decelerated for a third straight quarter (per Investing.com), raising concern that AI is impairing search monetization (per MarketWatch). Meanwhile, our signals dashboard reads the AI infrastructure capital spending cycle in slowdown — even with spending still running 80.3% above last year — which acts as a headwind for equities across both themes.

How that build-out is paid for separates the giants from the leveraged builders. Microsoft funded its expansion from $33.6 billion in quarterly net income (per The Verge), whereas Alphabet posted a second consecutive quarter of negative free cash flow at $9.07 billion (per Investing.com) and Oracle carries our active warning for cash burn with rising debt despite its new $20 billion fundraising cap. For debt-funded cloud builders like CoreWeave ($CRWV), the strain is direct: CoreWeave's capital spending ran at 298% of operating cash flow over the past year while long-term debt rose 185% and operating profit fell short of interest expense. Bond yields on CoreWeave debt reached 15% and credit-default swap spreads hit roughly 1,100 basis points earlier this month (per Motley Fool), while Japanese corporate credit-default swaps widened by the most since 2022 on global AI credit worries (per MT Newswires). Sustained capacity delays or tighter credit markets would confirm the risk.

Company-specific warnings also remain active across the themes: Super Micro Computer ($SMCI) carries warning language in its filings, while Coherent ($COHR) and USA Rare Earth ($USAR) carry warnings for heavy dilution.

The companies

Vertiv ($VRT), which rides our compute and power themes, rose 16.5% to $242.94 on Wednesday — about 3.7 times its typical daily move after allowing for how the tracked companies moved. Before the open, Vertiv reported third-quarter net sales of $4.31 billion, up 61.2% year over year, as organic orders more than doubled and adjusted operating margin expanded 290 basis points to 25.2% (per StockStory). It also filed an 8-K before the open and its third-quarter 10-Q after the close. The beat and raised full-year guidance align with our reading that Vertiv turns 25% of revenue into free cash flow after stock pay, though its valuation sits at the 90th percentile of its own history.

CoreWeave ($CRWV) and Nebius ($NBIS) gained 7.3% to $63.93 and 7.0% to $182.34 during Wednesday's session, with CoreWeave welcoming news that its Denmark AI capacity went live (per Motley Fool). After the close, however, Microsoft's third-party capacity delays and Alphabet's cash burn sent CoreWeave and Nebius down 6.1% and 6.5% in Thursday premarket trading (per Investing.com). That reversal matches our adverse reading on CoreWeave, where contracted backlog growth of 245% collides with warning language in its latest filing and cash burn after stock pay equal to 188% of revenue.

GE Vernova ($GEV), which rides our power theme, fell 1.9% to $878.03 on Wednesday even though third-quarter organic orders rose 96% to $29.3 billion, backlog reached $197 billion, and 2026 gas turbine pricing is running roughly 50% above 2025 levels (per 24/7 Wall St.). After the close, Citigroup, TD Cowen and President Capital lowered their price targets while RBC raised its target to $1,230 (per MT Newswires).

Aeva Technologies ($AEVA), Energy Fuels ($UUUU), PDD Holdings ($PDD) and USA Rare Earth ($USAR) had no material company-specific news or filings in Wednesday's session.

The backdrop

Equities edged higher on Wednesday before the mega-cap earnings arrived: the S&P 500 ETF ($SPY) rose 0.3%, the Nasdaq 100 ETF ($QQQ) gained 0.6%, and the Nasdaq Composite added 0.3%. Semiconductor shares led as the Semiconductor ETF ($SMH) climbed 1.7%, outpacing the Technology Sector ETF ($XLK) at 0.8% and the Software ETF ($IGV) at 0.1%. Among the 68 tracked companies with a move in Wednesday's session, 43 rose and 25 fell, with a median gain of 0.7%; overall, the median tracked company sits at the 78th percentile of its own valuation history. Meanwhile, the 10-year Treasury yield rose five basis points to 5.05%, WTI crude oil gained 2.9% to $102.78, and $VIX fell 3.5% to 16.91.
