Big Tech’s AI Spending Sparks Historic Debt Surge
Corporate borrowing tied to artificial intelligence is accelerating at an unprecedented pace, with Big Tech companies issuing record amounts of debt to finance the data centers, chips, and cloud infrastructure required for large-scale AI deployment.
Key Takeaways
- AI-related debt issuance surged to a record $120B in 2025, up over 500% from 2024.
- Big Tech could raise about $142B in AI debt in 2026, with upside risk toward $317B.
- AI spending is reshaping corporate debt markets as infrastructure costs explode.
In 2025, major technology firms raised roughly $120 billion in corporate debt linked to AI investments, according to BofA Global Research. That represents a more than 500% increase compared with 2024 and exceeds the combined issuance of the previous four years, underscoring how quickly capital needs have escalated as the AI race intensifies.
Hyperscalers prepare for even higher funding needs
The surge has been driven by hyperscalers expanding compute capacity at speed. Companies such as Amazon, Google, Meta, Microsoft, and Oracle are expected to increase debt issuance by around 18% in 2026, lifting total AI-related borrowing to roughly $142 billion under base-case estimates.
Analysts warn that the upside risk is substantial. In a more aggressive scenario, AI-driven issuance could reach as much as $317 billion next year, implying a 164% year-over-year increase as spending on data centers, power supply, advanced semiconductors, and networking accelerates.
A capital-intensive shift reshapes debt markets
The scale of borrowing highlights a structural shift in how technology growth is funded. Unlike earlier software cycles, today’s AI buildout requires massive upfront investment in physical infrastructure, locking companies into long-term spending plans that are increasingly financed through debt rather than internal cash flows.
For investors, this creates a new balance. AI remains a powerful growth driver, but the rapid accumulation of leverage raises questions around balance-sheet resilience, funding costs, and returns if revenue growth fails to keep pace. At the same time, the surge in issuance is reshaping the corporate bond market, with AI-related spending emerging as one of the dominant sources of new supply.
As 2026 approaches, markets will be watching whether borrowing stabilizes near current forecasts or accelerates toward the upper-end scenario. Either outcome would confirm that AI is no longer just a technological transformation – it is becoming a central force behind global corporate debt growth.
