A year ago, stable giants like Microsoft and Amazon absorbed the risk of the AI compute build-out. Now, they've stepped back, and smaller players like Oracle and CoreWeave, along with chipmakers financing their own sales, have taken on that risk. This shift to less stable, more circular financing models reveals the bubble's underlying fragility.

The AI boom is fueled by 'club deals' where large companies invest in startups with the expectation that the funds will be spent on the investor's own products. This creates a circular, self-reinforcing valuation bubble that is highly vulnerable to collapse, as the failure of one company can trigger a cascading failure across the entire interconnected system.
The call for a "federal backstop" isn't about saving a failing company, but de-risking loans for data centers filled with expensive GPUs that quickly become obsolete. Unlike durable infrastructure like railroads, the short shelf-life of chips makes lenders hesitant without government guarantees on the financing.
Unlike prior tech revolutions funded mainly by equity, the AI infrastructure build-out is increasingly reliant on debt. This blurs the line between speculative growth capital (equity) and financing for predictable cash flows (debt), magnifying potential losses and increasing systemic failure risk if the AI boom falters.
A new risk is entering the AI capital stack: leverage. Entities are being created with high-debt financing (80% debt, 20% equity), creating 'leverage upon leverage.' This structure, combined with circular investments between major players, echoes the telecom bust of the late 90s and requires close monitoring.
AI data center financing is built on a dangerous "temporal mismatch." The core collateral—GPUs—has a useful life of just 18-24 months due to intense use, while being financed by long-term debt. This creates a constant, high-stakes refinancing risk.
The AI infrastructure boom has moved beyond being funded by the free cash flow of tech giants. Now, cash-flow negative companies are taking on leverage to invest. This signals a more existential, high-stakes phase where perceived future returns justify massive upfront bets, increasing competitive intensity.
The enormous capital needed for AI data centers is forcing a shift in tech financing. The appearance of credit default swaps on Oracle debt signals the re-emergence of large-scale debt and leverage, a departure from the equity and free-cash-flow models that have characterized the industry for two decades.
Tech giants are no longer funding AI capital expenditures solely with their massive free cash flow. They are increasingly turning to debt issuance, which fundamentally alters their risk profile. This introduces default risk and requires a repricing of their credit spreads and equity valuations.
The current trend of AI infrastructure providers investing in their largest customers, who then use that capital to buy their products, mirrors the risky vendor financing seen in the dot-com bubble. This creates circular capital flows and potential systemic risk.
Companies like CoreWeave collateralize massive loans with NVIDIA GPUs to fund their build-out. This creates a critical timeline problem: the industry must generate highly profitable AI workloads before the GPUs, which have a limited lifespan and depreciate quickly, wear out. The business model fails if valuable applications don't scale fast enough.
