## Summary

Four major tech firms—Amazon, Microsoft, Alphabet, and Meta—reported record capital expenditure plans during recent earnings calls. They collectively aim to spend at least **$720 billion** on AI infrastructure this year, on top of **$1 trillion** in future commitments. Despite surging revenue in areas like Amazon’s fastest growth in five years and Meta’s booming ad revenue, none have yet turned AI investments into profit, raising investor concerns about returns.

Wall Street reacted sharply to the spending announcements, triggering a selloff in tech stocks. Alphabet’s stock dropped **13%** in a single day after its chief business officer acknowledged that AI-driven search features like AI Mode are reducing monetization in core Search ads, which grew only **12%**—down from **17%** year-over-year. Executives, including Alphabet’s CFO Anat Ashkenazi and Amazon’s CEO Andy Jassy, signaled further increases in 2027, framing the investments as critical for long-term growth. Meta’s CEO Mark Zuckerberg noted that its AI agent program, Muse, may only become profitable if compute costs drop **tenfold** next year, requiring heavy spending. Meanwhile, Anthropic’s third-quarter revenue surged to **$17 billion**, but compute costs hit **$17.5 billion**, leaving it with a net loss. The startup also committed nearly **$900 billion** to future data center builds, including purchases of Google’s TPU chips.

## Key points

- Amazon, Microsoft, Alphabet, and Meta plan **$720B** in AI infrastructure spending this year, plus **$1T** in future commitments
- Alphabet’s Search ad revenue grew **12%** (vs. **17%** last year) as AI features like AI Mode cut monetization
- Anthropic’s Q3 revenue hit **$17B**, but compute costs reached **$17.5B**, with **$900B** in future data center pledges

## Why it matters

The scale of spending—**$720B+**—shows Big Tech’s bet on AI as a long-term growth engine, but investors are growing impatient as profits remain elusive. Regulatory shifts post-midterms could force a slowdown, but for now, the race to dominate AI infrastructure continues unchecked.
