Today's signal
Zoho founder Sridhar Vembu posted on X this weekend calling AI "the biggest investment bubble yet," while being careful to add that the technology itself is real. He was reacting to a viral thread exposing what Wall Street analysts are now calling circular financing: Big Tech invests in AI startups, those startups are contractually required to spend that investment back on the investor's cloud infrastructure, and the investor then books that compute spending as fresh revenue from a paying customer. The same dollar, recognized twice.
Why it matters
This is not a theory. It is visible in SEC filings. When Microsoft invested $13 billion into OpenAI, the funds came primarily as cloud credits. OpenAI spent those credits on Azure. Microsoft recorded that usage as cloud revenue. One capital event, two balance sheet entries.
Amazon committed $8 billion to Anthropic under the same structure, with Anthropic agreeing to use AWS as its primary cloud provider in return. The accounting consequences hit Q1 2026 hard. Alphabet's record $62.6 billion quarterly profit included $28.7 billion in unrealized paper gains from its Anthropic stake, confirmed in its own 10-Q filing. No product sold, no customer served. Anthropic raised a round, Alphabet marked up its stake, and the paper gain flowed directly into reported profit. Amazon disclosed the same: $16.8 billion of its $30.3 billion Q1 net income came from Anthropic investment gains rather than operations, while its free cash flow collapsed 95% to $1.2 billion as it spent $44.2 billion on AI infrastructure.
The take
Vembu's framing matters precisely because of who he is. He is not a short seller. He built Zoho profitably without VC money, which gives him unusual standing to say: the tech is real, and the financial architecture around it is not. This mirrors the dot-com era's vendor financing schemes, where Lucent loaned money to telecom startups that used it to buy Lucent equipment, and Lucent booked the sales as revenue until real demand failed to show up. Today's version is fully legal under current FASB accounting rules. Legal does not mean sound. If your biggest customer and your biggest investor are the same entity, and the reported revenue exists only because of that relationship, you do not have organic demand. You have an engineered loop.
The number
$28.7 billion is the portion of Alphabet's Q1 2026 profit that came from marking up its Anthropic stake, per its own SEC filing. Not from search. Not from cloud. From updating a number on a spreadsheet.
