Will D&A as a share of revenue rise year-over-year for at least 3 of 4 big hyperscalers in Q3 2027 vs Q3 2026?
Years of heavy AI infrastructure spending are moving from construction into active use, and depreciation is catching up with that spending curve.
Who is on each side
The two sides.
Each side in DeepStack’s words, then the voices who argue it, attributed and paraphrased, dated where the date is known. A voice links to its page on DeepStack where one exists.
The case for yes
Depreciation compresses margins
AI infrastructure spending outpaces revenue growth, so depreciation and amortization climb as a share of sales at most of the four largest hyperscalers, Microsoft, Alphabet, Amazon, and Meta, squeezing reported operating margins compared with the peak of the spending boom. During the capex cycle, high spending lifts revenues elsewhere in the market while costs are amortized slowly, temporarily boosting market-wide margins; once depreciation catches up, that boost fades and true cash economics show through.
The case for no
The case against it
Depreciation and amortization stays flat or falls as a share of revenue at three or more of the four firms. This could happen if cloud and AI revenue grows faster than depreciation, companies extend useful-life assumptions or reclassify leases to slow reported depreciation growth, or infrastructure spending decelerates sharply in 2026 so the asset base in use stops outgrowing revenue.

Depreciation compresses margins
Nebius's financial reporting excludes GPU depreciation from cost of revenues, instead showing it separately. With 60 percent of GPU inventory idle, depreciation on deployed assets remains artificially low. When depreciation and product development…

CoreWeave, operating cash flow as a share of revenue, quarter ended September 30, 2026: whether it comes in at or above 24%.
On the Docket Pendingth031-t04Pre-specified
- Question
- Did the net cash from operating activities of CoreWeave for the quarter ended September 30, 2026 come to at or above 24.0% of its revenue?
- Source
- SEC EDGAR, XBRL company facts of CoreWeave (Forms 10-Q and 10-K)
- Rule
- Divide the net cash from operating activities by the revenue that CoreWeave reports for the quarter ended September 30, 2026 in its 10-Q or 10-K filing on SEC EDGAR. The answer is yes if the ratio is at or above 24.0%; no if it is below 24.0%.
- If the source is late, revised or silent
- If CoreWeave has not filed by November 16, 2026, or a filing restates a period the rule reads, the test is inconclusive, and the Result says what was read and what was missing.
- Base rate
- CoreWeave's operating cash flow as a share of revenue was 26.4% for the quarter ended June 30, 2026, by its filing on SEC EDGAR.
- Outside view
- A year earlier, for the quarter ended June 30, 2025, the same line read -20.7%, so the rungs sit on the last print.
- What would change the number
- A change in product mix, a one-time charge, or a reclassified line would move the reading.

In The Buildout
The Parts on the same question.
The stories that take up this thesis, with their own Calls and tests.
Part 04: AI Spending Has Met Its First Real Bill
AI’s buildout is entering its first financing test: spending outruns cash flow, investors have separated the winners from the believers, and the next budget will expose who is right.
Part 11: The Backlog Is Not the Quarter
AI suppliers report record order books. DeepStack reads the near book as revenue, the far book as a promise and the margin as the number that arrives last.
Part 14: The Cash Arrives Unevenly
Microsoft pays for its data centers from its own cash with room to spare. Alphabet and Meta now spend most of theirs and Amazon more than all of it; Alphabet and Amazon have covered the gap with stock and bonds. DeepStack reads the filings company by company and names the October 28 report that tests the view.
A thesis page states one question and both sides of it; DeepStack takes no side in words, and its view is the number it gives each test before the date. Analysis and opinion, not investment advice. Voices are paraphrased from public writing and attributed by name; DeepStack shows no score, ranking or accuracy for any person. Pre-specified means the words were approved on or before the test’s date. Specified after the date means they were written afterwards: such a test is counted and shown, and never rated. An open question has no words yet. The Call’s number is the chance, from 0 to 100, that the Call gives the yes answer to a test’s question, recorded before the test’s date; it is DeepStack’s own reading, not a market price and not advice. The readers’ mark on the same line is the readers’ median, the middle of the numbers signed-in readers gave the test, shown from 25 readers. The machines: Each model read this page and nothing else. The number that counts is the latest one each model gave before the test closed.
