AI Revenue Loop: Are Big Tech Cloud Deals Built on Circular Accounting?

TLDR:

• OpenAI and Anthropic make up over half of Big Tech’s $2 trillion future cloud backlog combined.
• Microsoft’s $13B OpenAI investment returned as cloud credits, then recorded as fresh revenue by Microsoft itself.
• Alphabet’s Q1 2026 record profit included $28.7B in unrealized paper gains tied to its Anthropic stake.
• Oracle has 54% of its entire $553 billion pipeline dependent on a single AI startup, OpenAI.

The AI revenue loop is drawing fresh scrutiny as analysts examine how major tech companies account for investments in AI startups.

Corporate filings reveal that OpenAI and Anthropic together account for more than half of the $2 trillion cloud backlog held by Microsoft, Oracle, Google, and Amazon.

Critics argue this structure relies on circular financial flows rather than organic market demand.

How the Round-Trip Revenue Model Works

A pattern has emerged across several major investment deals in the AI sector. A tech giant provides billions to an AI startup, often in the form of cloud credits rather than direct cash. The startup then uses those credits to rent computing infrastructure from the same company that funded them.

BullTheoryio described the arrangement plainly: “A tech giant gives billions of dollars to an AI startup as an ‘investment’. But hidden in the contract is a strict rule forcing the startup to hand that exact same money straight back to the tech giant to rent their computer servers.”

Microsoft’s $13 billion investment in OpenAI followed this structure. The funds came as cloud credits, which OpenAI spent on Microsoft’s servers. Microsoft then recorded that usage as cloud revenue from a paying customer.

OpenAI’s cloud spending has grown to over $60 billion annually, more than double its reported revenue of $25 billion. The gap is covered by continued recycled investment flows rather than external customer income.

Paper Profits and Real Cash Gaps Tell Two Different Stories

Beyond cloud revenue, tech companies are recording large paper gains tied to startup valuations. Each new funding round at a higher valuation triggers a mark-up on the investor’s books, which gets counted as profit.

In Q1 2026, Alphabet posted $62.6 billion in profit. However, $28.7 billion of that figure came from a paper markup on its Anthropic stake.

Amazon reported $30.3 billion in profit the same quarter, with $16.8 billion attributed to an unrealized Anthropic valuation gain.

Meanwhile, Amazon’s free cash flow fell 95% to just $1.2 billion, as the company spent $44.2 billion building physical data centers. The contrast between reported profits and actual cash positions is stark.

The concentration risk is also notable. Microsoft has 49% of its $627 billion future backlog tied to OpenAI. Oracle has 54% of its $553 billion pipeline linked to the same company.

Analysts have drawn comparisons to the 2001 dot-com collapse, when Global Crossing and Qwest Communications swapped fiber-optic capacity to manufacture fake sales.

Qwest later erased $1.4 billion in revenue, and Global Crossing filed for bankruptcy. Unlike those cases, the current AI accounting structures remain fully legal under existing rules.
