# DeepStack: Independent analysis of the AI economy

> The money behind the machine. Where informed investors disagree, the evidence each side stands on, and the date that settles it. DeepStack is an independent publication on the AI economy: the capital, the chips, the power and the people betting on all three. Sharp analysis, sourced numbers, a clear verdict. Every story gives the strongest case on each side, takes one in The DeepStack Call, and names the dated test that will settle it. Analysis and opinion, not investment advice.

DeepStack publishes at https://deepstack.ltd. The pages are free to read; quote with attribution and a link to the canonical page. Every figure carries its date and source. This file was generated 2026-10-22T01:47:05Z.

Questions typed into the search box or asked through the MCP tools are kept as text with the date, the tool used, the number of results, a session id, the name and version the calling program gives itself, the time the call took and a short digest of its arguments, and nothing that identifies you: no address, no user agent, no cookie. They are kept to decide what DeepStack covers next.

Signing in keeps your email (to send sign-in links, a reminder before a test you forecast closes and a note when it resolves, each with a one-click stop), the pseudonym you choose and each forecast with its time; never your IP address, your browser or a cookie. Deleting the account removes all of it at once.

## Stories

- [Part 01: Nvidia’s Demand Is Real. Its Financing Is Fragile.](https://deepstack.ltd/stories/nvidias-demand-insatiable-or-manufactured/): Google paid roughly double for Nvidia capacity while private credit financed a $35bn compute platform. The chips are scarce; the returns may be anything but.
- [Part 02: SpaceX Is Funding an AI Bet Before the Proof](https://deepstack.ltd/stories/spacex-after-the-ipo-exit-liquidity/): SpaceX’s $75 billion IPO puts AI infrastructure inside a profitable Starlink shell. The capacity looks plausible; the operating proof has not reached the meter.
- [Part 03: The Machines Will Work. The Debt Might Not.](https://deepstack.ltd/stories/the-debt-behind-the-machines/): AI demand may be real. The more dangerous question is who is financing the machines, and how quickly lenders can change their minds.
- [Part 04: AI Spending Has Met Its First Real Bill](https://deepstack.ltd/stories/the-market-stops-paying-for-faith/): Hyperscaler capital budgets are still climbing. The market has started charging for them, rewarding cash-backed returns and punishing faith.
- [Part 05: OpenAI and Anthropic Are Not the Same Business](https://deepstack.ltd/stories/anthropic-grew-142-percent-openai/): OpenAI is cutting prices while Anthropic still monetizes enterprise coding. The difference matters because hyperscalers, lenders and investors have priced the pair as one AI bet.
- [Part 06: Power Doesn’t Depreciate. Its Premium Moves.](https://deepstack.ltd/stories/power-doesnt-depreciate/): Electricity is the constraint, but the premium belongs to whoever can secure permission, build on time and turn a megawatt into revenue before demand catches up.
- [Part 07: The Fed Hiked. The Long End Still Climbed.](https://deepstack.ltd/stories/the-fed-hiked-the-long-end-kept-climbing/): The rate rise did not tame long yields. The bill for AI’s capital binge is arriving through bonds, deficits and the investors now setting the price of duration.
- [Part 08: AI Lenders Are Financing the End of Scarcity](https://deepstack.ltd/stories/the-scarcity-is-the-collateral/): The shortage of power, chips and data-center capacity supports lenders today. But every new dollar also brings the glut that can wreck their collateral.
- [Part 09: Habit Was the Moat. Agents Are Draining It.](https://deepstack.ltd/stories/habit-was-the-moat/): Meta’s Muse has inserted itself between shoppers and sellers. The first bill is coming due for businesses paid by customer inertia.
- [Part 10: The Bubble Is in the Denominator](https://deepstack.ltd/stories/the-bubble-is-in-the-denominator/): The S&P 500 looks cheaper because profits surged. But those profits depend on AI spending, chip values and debt that may be inflating the denominator while raising the discount rate.
- [Part 11: The Backlog Is Not the Quarter](https://deepstack.ltd/stories/the-backlog-is-not-the-quarter/): Ciena carries a $10 billion order book, Microsoft's far backlog grew three times as fast as its near one, and Nvidia now waits a year to be paid. The orders will ship. DeepStack expects the profit to arrive later, and the third-quarter reports to show the gap.
- [Part 12: The Model Is Not the Price](https://deepstack.ltd/stories/the-model-is-not-the-price/): A frontier model now lists at $4 per million input tokens, open and Chinese models carry most of the tokens on the platforms that count them, and the two labs' revenue is counted in the tens of billions. Investors agree the token is cheap. They differ on what the lab is paid for, and only a prospectus on EDGAR can settle it.
- [Part 13: The Ratepayer Pays First](https://deepstack.ltd/stories/the-ratepayer-pays-first/): Households in the nine jurisdictions PJM serves paid a median 11.7% more per kilowatt-hour over the year to July than the year before, against 5.6% elsewhere. Data center builders tell regulators they pay their own way. PJM's market monitor told them no state commission can shield households from the capacity price their demand sets.
- [Part 14: The Cash Arrives Unevenly](https://deepstack.ltd/stories/the-cash-arrives-unevenly/): Microsoft, Alphabet, Amazon and Meta spent 96 cents on property and equipment for each dollar of operating cash in the second quarter of 2026, up from 65 cents across 2025, by DeepStack's reading of SEC filings. Microsoft still pays from its own cash. Amazon spent $1.38 per dollar in the first half.
- [Part 15: Oil Is the Headline. The Real Yield Is the Bill.](https://deepstack.ltd/stories/oil-is-the-headline-the-real-yield-is-the-bill/): From February 27 to October 8, 2026, the 10-year Treasury yield rose 125 basis points, 115 of them real yield, while breakeven inflation rose 10, by DeepStack's reading of FRED. Retail diesel set a record in the week of September 21, 71% above the week of February 23, by the EIA's survey. The oil shock reaches the AI trade through the Fed and the real yield.
- [Part 16: The Seller Holds the Paper](https://deepstack.ltd/stories/the-seller-holds-the-paper/): Nvidia was owed 59.6 days of sales on July 26, 2026, against 45.4 in April, by DeepStack's arithmetic from its filings, and its guarantee table reached $108.5 billion from $3.5 billion, up to $105 billion of it signed in August for one Ohio campus and phased in from fiscal 2029. The buyers are real. Part of the money they pay with came from the seller.
- [Part 17: The Guarantee Has No Date](https://deepstack.ltd/stories/the-guarantee-has-no-date/): By mid-2026 the five largest builders of AI data centers had signed $1.12 trillion of leases not yet begun, by DeepStack's sum of their filings, 69% more than Moody's counted at the end of 2025. The leases reach the balance sheet on a schedule. The guarantees beside them have no date.
