The global race to build artificial intelligence infrastructure is reshaping the financial profile of the world’s largest technology companies. According to a new report from Moody’s Ratings, the unprecedented pace of AI investment is putting pressure on the balance sheets of hyperscalers such as Microsoft, Amazon, Alphabet, Meta, Oracle and CoreWeave.

While these companies remain among the strongest financially, Moody’s argues that the transition from software-driven, asset-light business models to capital-intensive AI infrastructure is creating new risks that investors and business leaders should closely monitor.

AI is Changing How Big Tech Invests

For decades, leading technology companies built their success on software, cloud services and intellectual property—businesses that generated high margins while requiring relatively modest capital investment.

Generative AI is changing that equation. Training and deploying advanced AI models requires massive data centers filled with high-performance GPUs, networking equipment and energy infrastructure. Instead of investing primarily in software development, hyperscalers are now committing hundreds of billions of dollars to physical assets.

Moody’s estimates that capital expenditures across the sector will reach approximately $785 billion in 2026, before climbing to nearly $1 trillion in 2027, marking one of the largest infrastructure investment cycles the technology industry has ever experienced.

Growing Investments Mean Growing Financial Pressure

The report highlights that these investments are beginning to affect free cash flow, even for companies with enormous cash reserves.

To finance AI expansion, many technology firms are increasingly relying on:

Corporate debt issuance
Equity offerings
Long-term financing arrangements
Off-balance-sheet infrastructure commitments

According to Moody’s, direct debt across the six companies analyzed has already reached roughly $460 billion. In addition, lease commitments for future AI infrastructure have expanded dramatically, totaling around $1.2 trillion, with more than $820 billion tied to data centers that are still under construction.

Although these lease obligations are not recorded as traditional debt, Moody’s considers them debt-equivalent liabilities because they commit companies to significant long-term payment obligations.

The Strongest Players Remain Well Positioned

Despite the warning, Moody’s does not believe the largest hyperscalers face immediate credit downgrades.

Microsoft, Alphabet, Amazon and Meta continue to maintain exceptionally strong balance sheets and investment-grade credit profiles. Their diversified businesses, growing cloud revenues and long-term enterprise contracts provide substantial financial resilience.

The report suggests that greater pressure is likely to fall on companies with weaker credit positions, particularly Oracle and AI cloud provider CoreWeave, both of which depend more heavily on external financing to support rapid infrastructure expansion.

A Circular AI Economy Is Emerging

One of the report’s more interesting observations concerns the increasingly interconnected nature of the AI ecosystem.

Large cloud providers have invested billions of dollars in AI startups such as OpenAI and Anthropic. Those same AI companies then spend enormous amounts on cloud computing services supplied by their investors.

This creates what Moody’s describes as a circular AI ecosystem, where technology giants both finance and serve many of the same customers.

While this model accelerates AI development, it also concentrates risk. If demand for AI infrastructure slows or investment assumptions change, multiple companies across the ecosystem could be affected simultaneously.

What This Means for Businesses

For organizations following AI adoption trends, the report highlights several important developments:

AI infrastructure has become one of the largest capital investment cycles in technology history.
Cloud providers are making long-term financial commitments based on continued growth in AI demand.
Financial performance will increasingly depend on whether these investments generate sustainable returns.
AI adoption is becoming closely tied to large-scale infrastructure ownership, creating higher barriers to entry for smaller competitors.

The Bottom Line

Moody’s believes the AI revolution remains financially sustainable for today’s largest technology companies, but it also marks a significant shift in how the industry operates.

Rather than relying primarily on software economics, hyperscalers are evolving into infrastructure-heavy businesses that require continuous investment in data centers, specialized hardware and energy resources. As AI spending approaches the trillion-dollar mark annually, investors will increasingly evaluate whether these massive capital commitments translate into long-term profitability and competitive advantage.

For businesses adopting AI, the message is equally important: the next phase of artificial intelligence will be defined not only by more capable models, but also by the enormous infrastructure required to power them.
