AI Funding Loop Sparks Regulatory Concerns

Introduction

The AI boom has a funding engine, and a significant portion of it appears to be AI companies writing checks to other AI companies.

The Circular Funding Model

The basic loop is simple to sketch. Company A invests in Company B. Company B then spends that money buying products or services from Company A. Everyone's revenue goes up, and everyone's valuation looks healthier.

The Numbers

The most detailed data comes from the Bank for International Settlements. BIS Bulletin 137, published on October 1, 2026, examined funding flows across 1,246 AI firms between 2021 and 2025.

The Supply-Chain Angle

The supply-chain angle is where things get especially tangled. BIS found that 58% of intra-AI deal value involved commercial supply-chain relationships. That means investors were frequently also suppliers, customers, or both.

Foreign Capital

The circular model has attracted substantial capital from abroad. Savings from surplus economies like South Korea, Japan, and Taiwan have been drawn in to help fund US data centers.

Macro Implications

The core concern is distorted demand signals. If a meaningful share of AI revenue traces back to investments made by the sellers themselves, those signals get noisy. A company might look like it has booming demand when part of that demand is its own capital coming back as orders. Heavy interconnectedness is the second risk. The BIS figures suggest AI firms are deeply entangled with one another through equity, supply contracts, and customer relationships.

Key Takeaways

For investors, the practical takeaway is to look past top-line revenue growth. Disclosures around related-party deals, vendor financing, and equity stakes held by suppliers deserve extra scrutiny. So do restructurings like the one that reshaped the reported Nvidia and OpenAI figures. On the macro side, the flow of foreign capital into US data centers is worth tracking closely. A shift in savings patterns in South Korea, Japan, or Taiwan, or a change in appetite for US tech assets, could affect funding for the buildout.
