Hyperscalers’ Debt Burden: A Warning Sign for the AI Boom?

The recent warning from Apollo Global Management about the escalating credit risk of hyperscaler debt has sent ripples through the tech industry. Behind the scenes of the AI boom, a worrying trend is unfolding – one that could have far-reaching implications for the companies at its core.

Companies like Alphabet, Amazon, Meta Platforms, and Microsoft are financing their AI development and deployment largely through debt. This approach comes with significant risks, as Torsten Slok, chief economist at Apollo, pointed out: “a debt-financed AI capex cycle with rising leverage, negative free cash flow, and uncertain payback on depreciating assets” is taking center stage.

The widening gap in credit default swaps (CDS) between hyperscalers and banks – now at around 60 basis points since October 2025 – should be a red flag. This implies that these companies’ debt is becoming riskier on its own terms, not just due to increased bank hedging.

The timing of this warning couldn’t be more pertinent, as the leaders of frontier LLMs expressed concerns over safety and potential regulation last weekend. This might seem unrelated, but it’s actually a symptom of the same problem: hyperscalers are increasingly shouldering liabilities for the actions of autonomous agents.

Some analysts argue that companies seeking legislation to shield them from competition and potential legal liability is merely “regulatory fatigue.” However, others see this as a genuine concern. Dan Alpert likened their push for regulation to the Communications Act treatment afforded social media platforms, highlighting the precarious position these companies find themselves in.

The notion that banks have built robust fortress balance sheets since the mortgage crisis provides little comfort. As Alpert noted, “that is where the answer may lie in terms of the way the market is looking at credit risk.” This dichotomy – between the financial resilience of traditional institutions and the debt-fueled ambitions of hyperscalers – should give investors pause.

Despite rising CDS prices and growing concerns, technology investors remain optimistic. They argue that increasing margins for hyperscalers justify the debt issuance and that it’s too soon to worry about the widening CDS spreads. Paul Meeks predicted “we’re starting to see a turn to the positive in their margins,” but this might be wishful thinking.

The statistics on these companies’ financial health are sobering: forward debt-to-equity ratios range from 7.34% for Microsoft to 34% for Meta Platforms, and all but Microsoft have negative free cash flow. These companies are living on borrowed time.

As the Apollo warning suggests, policymakers should take heed of this situation. Dean Baker astutely observed that “CDS investors, who are the most sophisticated investors anywhere, are attaching far greater risk to the debt of the most profitable companies in the world.” They obviously think there’s a substantial risk that AI companies cannot make good on their commitments.

The future of the AI boom hangs precariously in the balance. As hyperscalers continue to pour money into this sector, it’s essential that we don’t ignore the warning signs. The stakes are high: if these companies falter, the consequences could be catastrophic for the entire tech industry and beyond.
