S&P warns all major hyperscalers burning cash as AI capex hits record levels

The five largest cloud infrastructure companies have collectively spent $1.1 trillion on capital expenditures over the past five years, and the bill is only getting larger. Analyst estimates compiled by Visible Alpha project another $5.3 trillion through 2030, according to an analysis published Tuesday by S&P Global Market Intelligence. The report warned that the central risk now confronting the so-called "Hyper 5" — Amazon Amazon.com, Inc. ↘ 0.60%, Alphabet ↗ 0.02%, Microsoft ↘ 1.15%, Meta ↘ 0.53%, and Oracle ↗ 2.36% — is the shift from cash-funded to debt-funded investment before returns justify the outlay.cfodive

Cash Flow Turns Negative Across the Group

The pressure is already visible in quarterly results. Alphabet posted negative free cash flow of $5.9 billion in the second quarter of 2026, the first time the company has burned cash in a quarter since its 2004 IPO, after capital expenditures reached $44.9 billion against $39.1 billion in operating cash flow. Amazon reported that its trailing twelve-month free cash flow swung to negative $7.6 billion for the period ended June 30, down from positive $18.2 billion a year earlier, as spending on property and equipment rose $66.1 billion. Meta's second-quarter free cash flow fell 91% year over year to $784 million as capital expenditures surged 83% to $31.1 billion.everything-pr+2

A separate S&P Global Ratings report published in late August projected that all six major U.S. hyperscalers — the five plus SpaceX — will generate negative free operating cash flow in both 2026 and 2027, with no recovery expected before 2029. Combined capex across the group is projected to exceed $1.3 trillion by 2027, nearly triple its level two years prior.monitordaily+1

Debt Markets Fill the Gap

S&P Global Market Intelligence found that investment intensity, measured by comparing capital expenditures to depreciation, has exceeded peaks from both the dot-com era and the Great Recession. The companies are increasingly turning to debt, equity issuance, and lease commitments to keep construction on track.securities+2

Timothy Murray, a capital markets strategist at T. Rowe Price, noted in a May analysis that investor tolerance is beginning to shift. "The sustainability of that cycle remains an open question — particularly as capital intensity rises and free cash flow comes under pressure," Murray said.cfodive

Profitable but Stretched

The S&P Global Market Intelligence analysts, Liam Hynes and Drew Bowers, noted that the current AI investment boom has not yet taken on the financial risks that made the dot-com bubble vulnerable. The companies leading the spending remain highly profitable, but their cash cushion is shrinking. The S&P 500 cash-to-capex ratio reached 330% in 2021 — three times the level at the dot-com peak — and has been unwinding since as the AI buildout accelerates.cfodive

Oracle's credit trajectory illustrates the outer edge of the risk. S&P cut the company's rating to BBB- in July, one notch above speculative grade, after free cash flow ran negative $23.7 billion in fiscal 2026. "The key risk is the transition from cash to debt-funded investment before returns validate the spending," Hynes and Bowers wrote.marketbeat+1
