The Circular Financing Loop

In September 2025, Nvidia agreed to invest up to roughly $100 billion in OpenAI, which committed to buy millions of Nvidia GPUs. Oracle signed a $300 billion cloud deal with OpenAI while buying $40 billion in Nvidia chips. AMD handed OpenAI warrants against a chip commitment. Draw the map and a small cluster of the biggest names in AI appears to be funding each other in a loop, each able to book the other's deal as revenue. Critics called it circular financing; bulls called it real demand accelerating.

For founders and operators, this case sharpens the most important question you can ask about any reported number: where did the money actually come from? It trains you to scrutinize revenue and demand signals inside any ecosystem thick with inter-party investment, and to recognize a pattern that has appeared in defense, real estate, and telecom before. The resolution of which case is true here is exactly what you should not assume.
