A key red flag in the AI sector is circular financing, where a company like NVIDIA invests in a startup that then uses the funds to purchase NVIDIA's products. This creates a closed loop that can artificially inflate revenue and demand metrics, a tactic reminiscent of the dot-com bubble.

Major cloud providers like Amazon are making multi-billion dollar investments in AI startups like Anthropic, which then commit to spending that money back on the provider's cloud services. This "circular" financial arrangement locks in future revenue and inflates growth metrics with non-organic activity.

A significant portion of AI industry revenue is illusory, consisting of circular payments. For instance, NVIDIA invests in a company like OpenAI, which then uses the funds to buy NVIDIA's chips. This creates the appearance of strong revenue growth while masking the industry's financial fragility.

A massive portion of cloud providers' growth comes from just two AI companies, OpenAI and Anthropic. Since these same providers (e.g., Microsoft, Google) are also major investors in those startups, it creates a circular economy where investment capital flows directly back as revenue for compute.

Tech giants like Google and Amazon report massive profits partly from paper markups on their investments in AI labs like Anthropic. These labs then spend the investment capital on cloud services from their investors, creating a fragile, self-referential financial ecosystem.

The AI ecosystem appears to have circular cash flows. For example, Microsoft invests billions in OpenAI, which then uses that money to pay Microsoft for compute services. This creates revenue for Microsoft while funding OpenAI, but it raises investor concerns about how much organic, external demand truly exists for these costly services.

Major cloud providers invest billions in AI labs like Anthropic and OpenAI, who then commit to spending those billions back on the providers' cloud services. This circular flow significantly inflates revenue backlogs, raising questions about whether the growth is sustainable or symptomatic of an AI bubble.

Companies like NVIDIA invest billions in AI startups (e.g., OpenAI) with the understanding the money will be spent on their chips. This "round tripping" creates massive, artificial market cap growth but is incredibly fragile and reminiscent of the dot-com bubble's accounting tricks.

A circular economy is forming in AI, where capital flows between major players. NVIDIA invests $100B in OpenAI, which uses the funds to buy compute from Oracle, who in turn buys GPUs from NVIDIA. This self-reinforcing loop concentrates capital and drives up valuations across the ecosystem.
