Goldman Sachs: Surging AI Capex to Weigh on 'Magnificent 7' Return on Equity

Goldman Sachs warns that the AI capex boom will weigh on Big Tech's ROE for years, with consensus forecasting an average 7-percentage-point decline next year — making the payoff question the single most important pricing issue for these stocks.

01

Why is ROE suddenly in the spotlight?

ROE — return on equity, measuring how much net profit a company generates from shareholders' capital — is a core gauge of management efficiency.
Goldman strategist Ben Snider flagged in a new note that the AI capex wave will keep pressing down Big Tech ROE over the near-to-medium term.
This means → the money is going out the door, but profits haven't caught up yet; falling ROE is the direct reflection of that timing gap.
02

Whose ROE takes the biggest hit?

Consensus expects the Magnificent Seven's ROE to drop an average of roughly 7 percentage points next year.
The steepest declines are projected for Nvidia (NVDA) and Apple (AAPL).
In plain terms = even the "picks-and-shovels" play Nvidia and the steadiest cash-flow machine Apple cannot escape the dilution this capex cycle brings.
03

How much money are we talking about?

2026 hyperscaler capex is projected at roughly $700–725 billion, up about 77% from the already record $410 billion in 2025.
The breakdown: Amazon at ~$200B, Microsoft at ~$190B, Alphabet at ~$175–185B, Meta at ~$125–145B.
Goldman sees Wall Street's 2027 consensus of ~$920 billion as too conservative and forecasts capex could top $1.1 trillion.
04

Will the spending stop?

Tech executives have broadly signaled the AI infrastructure arms race will run through 2027 and beyond — this is not a one-off peak.
This means → the pressure on ROE is structural, not a one-or-two-quarter blip.
This reflects a deeper signal: the industry now treats AI infrastructure as a cost it *must* bear, not an investment it *could* make.
05

What does this mean for share prices?

Market skepticism is rising over whether massive outlays can translate into strong margins, earnings, and cash flow.
In plain terms = spending is easy; earning it back is hard — investors now want to see revenue delivery, not bigger capex numbers.
Whether Big Tech can prove a return on its capex will be the pivotal validation point for stock performance.
