AI investment growth is expected to peak this quarter – Goldman Sachs

What happened

Goldman Sachs economist Jan Hatzius expects growth in artificial intelligence investment by hyperscalers to peak this quarter. Hyperscaler investment is projected to reach about 1.5% of U.S. GDP in the fourth quarter of 2026, and top hyperscalers' capital spending is projected at roughly $725B-$800B this year.

Confirmed

Global impact / market context

Hyperscalers are companies that run large data centers. Their heavy spending on AI infrastructure supports demand for chips, servers, and cloud capacity. If investment growth peaks, the fastest support for those suppliers may fade, shifting attention to whether AI spending produces enough revenue and profit to justify the cost.

Analyst inference

Goldman's projections suggest AI-related stocks could rise 55% and other stocks 20% in the best case, while its baseline has both groups growing in line with assumptions. Alphabet, Microsoft, Meta, and Amazon report earnings this week, making their capital spending plans and AI revenue a near-term focus for investors.

Analyst inference

What to watch

1. Alphabet, Microsoft, and Meta Platforms are set to report earnings on Wednesday, and Amazon will report on Thursday, giving updates on AI spending and revenue. Confirmed
2. Goldman's projection that hyperscaler investment as a share of U.S. GDP peaks near 1.5% in the fourth quarter of 2026 is a forecast to compare against later data. Proposed
3. Watch whether hyperscalers keep raising capital spending guidance or signal a slower pace, which would affect suppliers of chips and data-center equipment. Analyst inference
