Big Tech AI debt spree reshapes credit markets

What happened: Major U.S. tech companies, including Amazon, Alphabet, and Meta, are borrowing heavily to fund their artificial intelligence (AI) buildout. In 2026 alone, debt issuance has already surpassed Wall Street projections, reaching $430 billion by May. Google recently issued a $25 billion bond, further pushing yields up as investor demand cools. By the end of 2026, AI-related corporate debt is expected to reach $570 billion. Moody's warns that this unprecedented spending threatens the credit quality of these hyperscalers, eroding free cash flow and increasing balance-sheet risk.

Market impact: The AI debt spree is reshaping credit markets, with bond spreads widening for tech giants. Investors are becoming more selective, driving up yields and making it more expensive for these companies to borrow. Junk bond ETFs, heavily exposed to tech debt, could face increased risk. The AI arms race is also causing anxiety in the bond market, with investors uncomfortable with the capital needed for the AI buildout.

What to watch next: In the coming months, investors should closely monitor the debt issuance plans of major tech companies, particularly Alphabet's and Meta's, which are expected to raise significant capital. The next earnings reports from these companies, scheduled for late July and early August, will provide insights into their AI spending and cash flow management. Additionally, any changes in credit ratings or further widening of bond spreads for these hyperscalers could signal a shift in investor sentiment towards tech debt.
