Alphabet pivots to AI as hyperscaler capex hits $667B, 62% growth
Alphabet is part of hyperscaler capex forecast rising to $667 billion in 2026, up $127 billion (62% y/y), consuming about 92% of cash flow from operations. Buybacks fell from 43% to 16%, with hyperscalers reinvesting nearly all free cash into AI infrastructure could climb to $700–725 billion under upside scenarios.
1. Capex Growth Projection
Wall Street consensus now projects hyperscaler capital expenditures to reach $667 billion in 2026, a $127 billion increase since the start of Q4 and a 62% year-over-year jump. This forecast marks the highest capex level for hyperscalers, driven primarily by investments in AI compute, data centers, networking and power capacity.
2. Cash Flow Consumption
At the projected spending level, capex would consume approximately 92% of hyperscalers’ cash flows from operations, a record high that sharply reduces available free cash. This shift contrasts with the post-GFC era when hyperscalers returned significant cash to shareholders via buybacks and dividends.
3. Shift Away from Buybacks
Hyperscaler share repurchases have plunged from about 43% of cash flow allocations at the start of 2023 to just 16% today, reflecting a strategic reallocation of funds. Some firms, including Alphabet, have supplemented funding with debt issuance to support the AI infrastructure buildout.
4. Outlook and Investor Impact
Goldman analysts suggest upside scenarios could push hyperscaler capex toward $700–725 billion, while growth rates may decelerate in H2 2026. A slowdown could improve free cash flow visibility and shift valuation back toward earnings metrics, but investors face a trade-off between near-term returns and long-term AI dominance.
