Tech stocks slide as investors question the returns from massive AI spending

US technology shares fell sharply for a second day as investors questioned whether escalating AI infrastructure costs will produce sufficient returns. Intel lost 28%, Reddit fell 29% and Roblox dropped 18%, while Alphabet continued declining after saying AI search summaries were affecting advertising revenue. Five major firms are committing about $800 billion to 2026 spending, and Amazon plans $220 billion. Analysts cited weaker earnings signals, cash outflows and rising skepticism, although the Nasdaq remained above its level a year earlier.
Editorial summary · Publisher article
What matters
- Alphabet expects up to $205 billion in investment this year, largely tied to AI.

- Amazon said its cash spending increased six-fold over three months and exceeded cash generation.
A market pullback, not yet a full reversal
The Nasdaq ended October down 2.8%, its worst monthly performance since March 2025, but remained up 7.8% over the prior year. Amazon was also still higher year on year, while Alphabet was slightly lower.
