Microsoft to Allocate 92% of Free Cash Flow as Big Tech Capex Soars to $667 Billion
Wall Street projects hyperscaler capital expenditures will reach $667 billion in 2026, up $127 billion since Q4, equating to 62% year-over-year growth and consuming roughly 92% of operating cash flow. Microsoft and peers have cut buyback allocations from 43% to 16%, funneling nearly all free cash flow into AI infrastructure.
1. Capital Expenditure Surge
Goldman Sachs projects hyperscaler capital spending will hit $667 billion in 2026, a $127 billion increase since the start of the fourth quarter that implies 62% year-over-year growth in infrastructure investment.
2. Free Cash Flow Compression
That spending surge is set to consume about 92% of collective operating cash flow at Microsoft and other hyperscalers, driving buyback allocation down from 43% at the start of 2023 to just 16% today.
3. Microsoft’s Strategic Pivot
Microsoft is redirecting nearly every dollar of internally generated cash into AI compute, data centers, networking and power capacity, shifting the capital-allocation focus away from shareholder distributions toward scale and performance.
4. Investor Implications
With capex growth expected to decelerate in the second half of 2026, visibility on a free cash flow trough may prompt investors to reassess valuation on earnings rather than reinvestment narratives.
