Big Tech, known for its abundant cash, is building an AI empire on a mountain of debt, with Europe feeling the impact. The five biggest builders of AI data centers in the US—Alphabet, Amazon, Meta, Microsoft, and Oracle—have doubled their combined debt to approximately $350 billion over five years.
According to Bloomberg’s data compilation:
These tech giants are betting that cutting-edge AI will eventually repay this massive investment. However, for now, interest payments remain a negligible fraction of their cash flow. In 2025, the five companies collectively paid around $10 billion in debt interests—a significant increase from 2019 but still modest considering Google’s quarterly cash flow of roughly $64 billion.
Strain and Changing Market Dynamics
The financial strain is becoming more apparent. Amazon experienced a negative free cash flow in the March quarter, while Oracle’s debt-to-sales ratio climbed to 2.5 times, prompting S&P to downgrade its rating to one notch above junk status, citing excessive AI spending.
Investors have been eager to purchase these tech giants’ bonds, but the market dynamics are shifting. Amazon’s $25 billion bond sale this week received a tepid response, indicating a potential shift in investor confidence. Traders are offloading older tech company bonds, including those from Amazon, Nvidia, and Oracle, to make space for the influx of new debt.
European Implications: A Growing Debt Market
With limited dollar borrowing options, American tech companies are turning to Europe. Morgan Stanley predicts that US hyperscalers will borrow approximately €50 billion in euros this year, surpassing France as the largest corporate debt contributor in the eurozone.
This shift has significant consequences for European startups and infrastructure funds that rely on the same Euro debt market. A Munich or Paris-based startup without AI involvement may face higher borrowing costs due to the increased demand from Big Tech.
Historical Context: Lessons from Intel
Not all are concerned. Amazon CEO Andy Jassy expresses high confidence in monetizing the debt, while Mark Zuckerberg maintains that demand for computing power continues to outpace supply. Some analysts, like Gil Luria of DA Davidson, consider the debt load manageable. However, others, such as Fitch’s Jason Pompeii, warn that excessive borrowing could prove detrimental, citing Intel’s missed AI chip opportunity and subsequent need for government bailout and Nvidia investment.
Conclusion: A Cautionary Tale
The rapid buildup of AI-related debt represents one of the largest corporate debt bets in history. As the race to dominate AI continues, the potential consequences for both tech companies and investors are substantial.
