Major US technology companies are borrowing at the fastest pace on record to fund AI infrastructure, pushing bond yields higher as investors grow more selective.
Major US technology companies are borrowing at the fastest pace on record to fund AI infrastructure, pushing bond yields higher as investors grow more selective.

Alphabet, Amazon, Microsoft, Meta and Oracle have raised more than $110 billion in combined debt and equity this year to finance their artificial intelligence buildout, pushing corporate bond yields higher as investor appetite for tech debt cools.
"The market is starting to question whether the returns on this capital will materialize within a timeframe that justifies the leverage," said Hans Mikkelsen, credit strategist at TD Securities.
Alphabet alone raised roughly $70 billion in debt and equity in 2026, doubling its long-term debt to $98.2 billion while suspending its buyback program. Oracle plans approximately $40 billion in new financing after burning through negative $23.7 billion in free cash flow in its fiscal 2026. Amazon's trailing free cash flow collapsed 95% to $1.2 billion as property and equipment additions surged, with total 2026 capital expenditures expected near $200 billion.
The borrowing spree leaves the five largest hyperscalers with a combined debt load exceeding $500 billion, according to company filings. If enterprise AI demand slows or GPU returns disappoint, the interest burden could compress profit margins by 200 to 400 basis points across the group, analysts at BNP Paribas estimated.
Alphabet's $70B Raise Signals Market's Breaking Point
Alphabet's financing activity illustrates the strain. The company raised roughly $70 billion through a combination of equity offerings and debt issuance, pushing its long-term debt to $98.2 billion from roughly $49 billion a year earlier. Chief Financial Officer Anat Ashkenazi warned in the company's second-quarter earnings call that "free cash flow will remain under pressure" as capital expenditures hit $44.92 billion in the quarter, up 100.1% year over year. The company's 2026 capex range now stands at $195 billion to $205 billion, up from an earlier $180 billion to $190 billion.
Oracle and Amazon Carry the Highest Leverage Risk
Oracle ranks as the most exposed hyperscaler by balance sheet metrics. The company posted negative $23.69 billion in free cash flow for fiscal 2026 while spending $55.66 billion on capital expenditures. Total liabilities reached $218.70 billion against shareholders' equity of just $43.06 billion. Oracle shares have fallen 50.53% over the past year.
Amazon faces the largest absolute capital commitment at roughly $200 billion for 2026. First-quarter capex alone reached $44.20 billion, up 76.7% from a year earlier. The company's Trainium chip commitments include roughly 2 gigawatts for OpenAI and up to 5 gigawatts for Anthropic, creating counterparty concentration risk if either customer renegotiates terms.
Microsoft's Cushion and Meta's Dual Exposure
Microsoft is the least exposed among the group, though its capital spending still reached $37.5 billion in the second quarter and $30.88 billion in the third, up 84.4% year over year. A 45.6% operating margin and $625 billion in commercial remaining performance obligations provide a buffer. Chief Financial Officer Amy Hood said GPU contracts for the largest customers "are contracted for the entire useful life of the GPU," limiting downside risk.
Meta Platforms raised its 2026 capex guidance to $125 billion to $145 billion, the largest single-year increase among peers, with no external cloud rental revenue to offset the spending. Reality Labs posted $4.03 billion in operating losses in the first quarter, and free cash flow grew only 11.7% to $12.39 billion despite 33.1% revenue growth.
The divergence in balance sheet quality is creating a clear winner-loser dynamic in hyperscaler credit. Microsoft's bonds trade at the tightest spreads, reflecting its operating margin and contracted GPU revenue, while Oracle's debt has widened by roughly 150 basis points this year, according to Trace data. For equity investors, the risk is concentrated: if one hyperscaler announces a capex plateau, the multiple compression would hit Oracle and Amazon hardest, followed by Alphabet, while Microsoft and Meta would face relatively less pressure.
