Short answer: trace money, obligations, and risk through the entire chain—AI company, investors, lenders, cloud providers, infrastructure builders, chip and server suppliers, resellers, and end customers. A financing loop is not automatically improper. The decisive question is whether reported growth would continue if supplier-linked funding, credits, guarantees, or purchase commitments disappeared. Test that counterfactual against contracts, revenue recognition, receivables, cash collections, customer concentration, and the buyer’s ability to pay independently.
What “circular financing” means in AI markets
Circular financing describes a situation in which money or credit travels around a commercial ecosystem and supports the same parties’ apparent growth. An investor may fund an AI company; that company may use the funds to buy cloud capacity, servers, chips, or data-center services from a related partner; the supplier may then report sales to the funded company or its customers. The loop can involve equity, debt, guarantees, vendor financing, prepaid capacity, credits, minimum-purchase commitments, or other forms of support.
The overlap of investor, supplier, and customer roles is not proof that sales are fictitious. A strategic investor can also sell real equipment. A cloud customer can genuinely consume capacity. The evaluation is a dependency analysis: how much growth relies on linked financing, whether products or services are transferred and used, whether payment is collectible, and whether purchases would continue without the support.

Ask: Could the customer pay for and renew the compute, equipment, or services using independent cash flow and financing if its supplier-investor or related partners stopped supporting it? If the answer is unknown, the correct conclusion is unresolved dependency—not fraud.

Build a dated map of every participant and obligation
Start with a diagram for each material transaction. Use separate arrows for cash and for non-cash support such as commitments, credits, guarantees, capacity reservations, or forgiveness. Date every event and label its status as completed, conditional, announced, or merely planned.
| Participant role | Evidence to collect | Why it matters |
|---|---|---|
| Investor | Equity subscription, closing conditions, valuation, follow-on rights | Shows who supplied capital and whether funding was actually received |
| Lender or guarantor | Loans, guarantees, covenants, maturity dates, collateral | Reveals leverage and support that may not appear as sales |
| Cloud or infrastructure provider | Capacity commitments, minimum spend, cancellation rights, pricing, credits | Distinguishes usage from a contractual promise to buy |
| Chip, server, or equipment supplier | Purchase orders, financing terms, return rights, payment schedules | Tests whether reported product demand is independently funded |
| AI company or intermediary | Cash, burn rate, debt, customer contracts, receivables, prepayments | Measures ability to pay and renew purchases |
| End customer | Who consumes the service, term, usage, cancellation and payment history | Separates real end demand from an internal funding loop |
For each arrow, record the legal counterparty, economic beneficiary, amount, currency, geography, reporting date, and whether the arrangement is enforceable. Keep a separate schedule for investments, loans, guarantees, vendor financing, customer credits, prepayments, infrastructure commitments, purchases, recognized revenue, receivables, and cash receipts. The same dollar amount can appear in several schedules but represent different economic events.
A disclosed example of an integrated arrangement
NVIDIA’s October 2025 investor presentation described its OpenAI partnership as “a powerful demonstration of NVIDIA’s ability as an AI infrastructure partner – delivering architecture, chips, systems, networking, data centers, software, operations, and financing as one integrated solution.” This is NVIDIA’s own marketing and investor-presentation language, not an independent finding. The presentation also said OpenAI would need to “re-invest future revenue and/or secure other sources of financing” to cover buildout costs. Those statements identify a potentially linked structure; they do not establish that NVIDIA’s revenue was financed by NVIDIA or that OpenAI could not pay independently.

Read the income statement and footnotes line by line. An investment can produce equity-method income, fair-value gains, interest, dividends, or other returns. None should be added to product or service sales when assessing operating growth.
Use the correct buckets
- Operating revenue: consideration for delivered software, cloud services, equipment, or other promised goods and services.
- Investment income: equity-method earnings, fair-value changes, dividends, or gains on a stake.
- Financing: borrowings, equity proceeds, guarantees, and credit facilities.
- Contractual commitments: future purchases or capacity reservations that may not yet have been paid or recognized as revenue.
Microsoft’s Form 10-Q for the quarter ended September 30, 2025 said it would account for $13 billion of total funding commitments to OpenAI as an investment under the equity method. The same filing described an incremental $250 billion Azure services purchase commitment under a new agreement. Those are material links to examine together, but the figures do not show that $250 billion had already been paid, recognized as revenue, or funded by Microsoft’s investment. Treat a commitment as a future obligation until the filing shows performance, invoicing, collection, and recognition.
SoftBank Group’s 2025 financial report said it had invested $2.2 billion in OpenAI through SVF2 since September 2024 and agreed on March 31, 2025 to make follow-on investments of up to $40.0 billion, subject to conditions and two closings. It reported completion of the first $10.0 billion investment on April 15, 2025. The report said SoftBank borrowed $8.5 billion from Mizuho Bank and other financial institutions to fund the first closing and lent the same amount to SVF2; after additional syndication, SVF2’s investment amount was reduced from $8.5 billion to $7.5 billion and SoftBank received $1.0 billion from SVF2. These are dated financing disclosures. They do not mean the full $40.0 billion commitment was completed or that OpenAI’s sales were financed by those proceeds.
Measure revenue quality, not just revenue growth
Fast growth can be genuine while still carrying concentration and collection risk. Build a period-by-period bridge that compares recognized revenue with cash and working-capital movements.
| Measure | What to calculate | Interpretation |
|---|---|---|
| Revenue versus cash | Recognized revenue, cash receipts, and operating cash flow | A widening gap calls for collection and contract diligence |
| Accounts receivable | Ending receivables, days sales outstanding, aging and write-offs | Rapid receivables growth can indicate delayed collection or front-loaded billing |
| Prepayments and credits | Customer deposits, rebates, credits, and deferred revenue | Shows whether cash arrived before delivery and who economically funded it |
| Contract structure | Committed versus on-demand usage, term, cancellation rights, remaining obligations | Tests durability of demand and exposure to termination |
| Customer mix | New customers, expansion with existing customers, direct and indirect end users | Reveals whether growth is broad or concentrated in linked buyers |
Use the disclosed NVIDIA figures with their qualifications
NVIDIA’s Form 10-K for the fiscal year ended January 25, 2026 reported total revenue of $215.938 billion, compared with $130.497 billion in fiscal 2025. Data Center revenue was $193.737 billion, compared with $115.186 billion in fiscal 2025. These figures establish rapid reported growth; they do not by themselves establish supplier-financed demand.
The same filing said two direct customers represented 22% and 14% of total revenue in fiscal 2026. It also said one AI research and deployment company contributed a “meaningful amount” of revenue by purchasing cloud services from NVIDIA’s customers; that passage did not identify the company. NVIDIA estimated indirect-customer revenue using customer purchase orders, product specifications, internal sales data, and other sources. Preserve that estimation caveat instead of presenting indirect exposure as a precisely observed customer total.
Receivables create a different risk from revenue concentration. As of January 25, 2026, three direct customers represented 25%, 18%, and 13% of NVIDIA’s accounts receivable. A customer can be a small share of current-period sales yet a large share of unpaid invoices, or the reverse. Analyze both percentages and the collection history.
Test whether the customer can pay without support
Construct a support-withdrawal scenario for each major buyer. Remove supplier loans, guarantees, credits, prepayments, equity proceeds earmarked for purchases, and minimum-spend subsidies. Then compare the buyer’s remaining liquidity with contractual payments and the cost of renewing capacity.
Checklist for independent payment capacity
- Unrestricted cash and liquid investments after committed capital expenditures.
- Debt maturities, interest expense, covenants, collateral, and available undrawn facilities.
- Cash burn and operating cash flow, separated from investment proceeds.
- Collections from the buyer’s own customers, including aging and concentration.
- Enforceable contracted revenue, renewal rates, cancellation rights, and minimum usage.
- Ability to replace the linked investor, lender, cloud provider, or equipment supplier.
- Whether the buyer can meet payment terms and renew capacity after support ends.
Run at least three cases: support continues as contracted; support is reduced or delayed; and all linked support ends at the next renewal. Compare liquidity, debt-service coverage, required equity, and capacity purchases in each case. If public filings do not provide contract-level cash receipts or side letters, state that the true counterfactual cannot be established publicly.
Apply the revenue-recognition rule precisely
FASB Topic 606 requires revenue to depict the transfer of promised goods or services in an amount that reflects the consideration an entity expects to receive. For a specific arrangement, establish an enforceable contract, commercial substance, performance obligations, transaction price, transfer of control, collectibility, and any consideration paid to the customer.
Consideration payable to a customer
Under Topic 606, consideration payable to a customer generally reduces the transaction price and revenue unless it is exchanged for a distinct good or service transferred by the customer. If the payment exceeds the fair value of that distinct service, the excess reduces transaction price. If the fair value cannot reasonably be estimated, all of the consideration is treated as a reduction of transaction price.
This rule matters when a supplier invests in a customer, grants credits, pays marketing allowances, provides rebates, or otherwise gives value to a party that purchases its goods or services. Do not assume that every equity investment is a customer rebate: determine whether the recipient is a customer for the arrangement, whether a distinct service is transferred, and whether the payment is at fair value. Review the contract, accounting policy, journal entries, and evidence of performance with qualified accounting advisers.
Distinguish completed funding from promises and announcements
Headline amounts often combine cash already transferred with conditional or future commitments. Use a status table rather than one total.
| Status | How to describe it | What to verify |
|---|---|---|
| Completed closing | Cash or securities transferred on a stated date | Settlement evidence, ownership, restrictions, and recipient’s use of proceeds |
| Conditional commitment | Available only after milestones, approvals, or other conditions | Conditions, expiry, termination rights, and probability of funding |
| Purchase commitment | Contractual obligation to buy services or capacity | Delivery, invoicing, cancellation, minimums, and recognition timing |
| Announced plan | Public intention without an executed or funded obligation | Definitive agreement and subsequent filings |
For example, SoftBank’s reported $40.0 billion figure was a proposed maximum follow-on investment under a March 31, 2025 agreement, with conditions governing the second closing. The $10.0 billion first closing was reported as completed April 15, 2025. Those two facts must not be merged into “$40 billion invested.”
Assess concentration and indirect exposure
Concentration is not circularity, but it determines how damaging a financing loop could be. Calculate the share of revenue and receivables attributable to the largest direct customers, then investigate indirect end-customer exposure through cloud providers, resellers, and customers’ customers.
Ask whether a named customer is purchasing for its own use, reselling capacity, or acting as an intermediary for an undisclosed end user. Examine purchase orders, product specifications, internal sales data, usage records, and payment history. When a company estimates indirect-customer revenue, present it as an estimate and explain the inputs and uncertainty.
Read regulatory questions in context
The SEC Division of Corporation Finance’s January 13, 2025 staff letter to CoreWeave asked about top-customer revenue, committed versus on-demand contracts, growth from new versus existing customers, debt service, and agreements with NVIDIA and MagAI Ventures. Staff questions identify areas requiring explanation; they are not findings of wrongdoing and should not be described as such.
Best Value
Use such correspondence to expand your checklist: request customer-level concentration, contract duration, cancellation provisions, payment terms, related-party agreements, debt-service schedules, and evidence of independent demand. A company’s response, subsequent filing, or audited disclosure may resolve a question; an unanswered question remains an evidence gap.
A repeatable evaluation workflow
- Set the period and perimeter. Choose the latest filing date, define the geography and entities included, and list every investor, lender, supplier, cloud provider, intermediary, and end customer.
- Build the flow map. Draw cash arrows separately from commitments, credits, guarantees, capacity, and other non-cash support. Mark each item completed, conditional, announced, or planned.
- Reconcile funding. Tie equity and debt proceeds to bank-cash movements, restricted cash, and stated uses. Do not treat an announced commitment as cash.
- Reconcile revenue. Tie reported sales to contracts, performance obligations, invoices, receivables, deferred revenue, and cash collections. Separate operating revenue from investment gains.
- Test consideration payable. Identify rebates, credits, investments, or services provided to customers and apply the Topic 606 analysis to each contract.
- Measure concentration. Calculate direct revenue and receivables concentration and investigate indirect end-customer estimates.
- Model withdrawal. Remove linked support and test whether the buyer can pay, renew, and service debt from independent resources.
- Classify the conclusion. Use “independent demand supported,” “supplier-supported demand,” “potential circularity,” or “counterfactual unknown” according to the evidence. Reserve accusations of fraud or fictitious revenue for documented proof.
Red flags that warrant deeper diligence
- Revenue and receivables rise much faster than cash collections without a clear contractual explanation.
- The largest customers are also investors, lenders, guarantors, cloud providers, or equipment suppliers.
- Large “commitments” lack delivery schedules, enforceable minimums, payment terms, or cancellation details.
- Customers depend on credits, prepayments, or financing from the same ecosystem to meet invoices.
- Growth is concentrated in existing linked customers while new-customer additions remain weak.
- Indirect-customer identities are aggregated and the company relies heavily on estimates.
- A buyer’s debt service or renewal payments require another round of equity from a related party.
- Contracts appear to exchange funding for purchases without evidence of distinct services at fair value.
None of these indicators proves misconduct. Each identifies a contract, cash-flow, or accounting question that must be answered with primary documentation.
What a strong conclusion looks like
A defensible conclusion names the specific links, dates, amounts, and evidence. It distinguishes cash investments from purchase commitments, direct from indirect customers, recognized revenue from cash collected, and completed funding from conditional promises. It states what would happen if support ended and identifies which facts remain private or unverified.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
For example, you might conclude that reported growth is real but highly concentrated and dependent on customer financing that has not yet been tested through a renewal cycle. Or you might find that contracts, usage records, collections, and independent liquidity support genuine demand despite overlapping investor and supplier roles. If contracts, side letters, and customer-level receipts are unavailable, say plainly that the standalone-demand counterfactual is unknown.
Key questions readers commonly ask
Is AI growth circular?
Some arrangements can be linked through investment, infrastructure purchases, and customer commitments, but overlap alone does not answer the question. Trace cash, obligations, delivery, collection, and the buyer’s ability to continue without support.
Are AI companies funding their own customers?
They may provide equity, credits, guarantees, prepayments, or financing to customers or intermediaries. Determine whether the value is consideration payable to a customer under Topic 606, a separate financing transaction, or payment for a distinct service at fair value.
Is vendor financing inflating AI revenue?
Vendor financing can increase a buyer’s purchasing capacity, but it does not by itself make revenue improper. Examine collectibility, transfer of control, payment history, cancellation rights, and whether the customer could pay without the vendor’s support.
Can the customer pay for compute without supplier support?
Answer by modeling cash, debt maturities, independent customer collections, contracted revenue, and renewal costs after removing linked loans, credits, guarantees, and equity proceeds. Public filings may not contain enough contract-level information to reach a definitive answer.
