AI’s borrowing boom is adding strain to US bond markets

Big tech firms have borrowed around $500 billion since January to fund AI chips, servers and data centres, as US government bond yields climb above 5.30%. Yahoo Finance reports that analysts see AI borrowing as one pressure on markets, alongside inflation and other forces.

What happened

The report says Google, Meta, Amazon, Microsoft and others have raised about $500 billion in debt in the nine months since January. Goldman Sachs expects technology-sector borrowing to reach $1.2 trillion in 2027. One adviser quoted by Yahoo Finance estimates that AI now accounts for 25% of corporate bond issuance, up from 4% two years ago.

The report also notes that Meta has had to offer investors more than 7% a year, while riskier data-centre companies have offered rates above 9%. The Yahoo Finance report says some analysts believe demand for technology-company bonds may be competing with demand for US Treasuries. It also describes inflation linked to the war against Iran and high energy prices as another force behind rising borrowing costs.

Why it matters

AI infrastructure is usually discussed in chips, power and construction. Debt adds another measure of the build-out’s cost, with possible consequences beyond technology firms: the report says the 10-year US Treasury yield has topped 5.30%, its highest level since 2002. That is a benchmark that influences borrowing costs across the economy, including mortgages and car loans.

The figures are not proof that AI borrowing alone drove yields higher. They do show why the financing of the AI boom is becoming a market story, not merely a corporate one.

Our read

The striking point is the scale: around $500 billion in technology borrowing in nine months, with more expected. That is a sizeable bill to fund a race whose returns remain uncertain. But pinning a broad rise in yields on AI debt alone would be too neat; the report also points to inflation and energy prices. Keep the borrowing figures in view, and treat any single-cause explanation with care.

What to watch

• Whether technology borrowing rises towards Goldman Sachs’ $1.2 trillion estimate for 2027.
• How yields and financing costs change for major technology firms and data-centre specialists.
• Whether AI-related revenue grows enough to support the scale of investment.

Discussion spark: If AI borrowing is helping push up the cost of credit, should technology firms slow their infrastructure build-out, or is that a price worth paying for future growth?
