Morgan Stanley calculates hyperscaler cloud infrastructure backlog at $2.3 trillion, with $1.4 trillion specifically directed to AI capex.

Investors who exited high-profile hyperscaler stocks because of surging AI capex may be overlooking an important point: Tech giants' cloud computing backlogs support their strong spending plans.

Across the top four cloud service providers, cloud computing backlogs now exceed $2.3 trillion, up 16% from the first quarter, according to Bank of America analyst Vivek Arya.

Microsoft reported commercial remaining performance obligations grew 8% sequentially to $678 billion in the second quarter, with only 30% recognized within the next 12 months. Oracle disclosed $638 billion of remaining performance obligations in its most recent quarter, with just 12% due in one year and 34% in two to three years. Amazon's AWS business disclosed $496 billion of backlog—up over 100% year over year—in its second quarter, while Google Cloud's backlog grew to approximately $514 billion, versus about $460 billion in Q1.

"Compute remains mostly supply constrained today, and we see increased hyperscale appetite to continue investing in capacity—backed by customer commitments and quickly accelerating AI sales," Arya wrote.

Investor concern around tech spending on AI capex is understandable given the scale and apparent acceleration, with no peak yet visible. Arya projected 2026 hyperscaler capex at over $860 billion, up 80% year over year, with a path toward approximately $1.2 trillion by 2027, representing 38% year-over-year growth. "Declining free cash flow remains a concern, but we see negative free cash flow margin to max out around -5-6% in 2027-2028, before likely returning to healthy profitability as AI investments proliferate," he explained.

The market may not currently value this dynamic, as investors would prefer executives to moderate spending. However, given recent valuation pullbacks on companies leading in lucrative cloud computing deals, this inflection point could prove significant—and these stocks may have already positioned themselves for double-digit gains.
