## Summary

Alphabet Inc. posted weaker‑than‑expected search revenue in its latest earnings, sparking investor concern that the company’s AI‑driven "AI Mode" may be cannibalizing its core search business.  Search still accounts for more than half of Alphabet’s 2025 revenue, but the slowdown prompted a sell‑off that saw the stock lose almost 19% in October, wiping out $758 billion in market value.  The share price now trades at about 18 times forward earnings, down from 29 times in February and below its 10‑year average of roughly 21.

Analysts linked the weakness to growing competition from AI agents such as Meta’s Muse product and warned that a lasting decline in search could further depress valuation.  Citi’s Andrew Boone downgraded Alphabet to market‑perform, and Yorkville Ives’ Dan Ives noted the first quarter where the “negative thesis around AI crushing search” has traction.  Wall Street cut 2026 earnings‑per‑share estimates by 4.5%, while some investors point to accelerating cloud growth and the lower multiple as potential upside.

Despite the concerns, some investors see the dip as a buying opportunity, noting Alphabet’s strong cash position and expanding cloud business.  The debate highlights how Google’s own AI advances may paradoxically threaten the search engine that made it dominant.

## Key points

- Alphabet reported weaker-than-expected search revenue in Q4 2025.
- Shares fell almost 19% in October, erasing $758 billion market value.
- Analysts cut 2026 EPS estimates by 4.5% amid AI competition concerns.

## Why it matters

Search drives over half of Alphabet’s revenue; a slowdown could reshape ad markets and investor valuations across the tech sector.
