Tech stocks fall on AI agent cannibalization fears

What happened

Tech stocks including GoDaddy (down 3.6%), Bandwidth (down 2.5%), and GitLab (down 4.2%) declined in the afternoon session, driven by broader sell-offs in Alphabet (roughly 6% decline) and Microsoft. The wider software and communications sectors followed mechanically given their index weight.

Why it matters

The market has been compounding concerns all year that AI agents—software systems that make decisions and take actions autonomously—will erode the traditional subscription model. This concern intensified after Accenture, the largest IT services firm, cut its growth outlook and explicitly cited AI compressing demand for traditional IT services, which investors extended to the software vendors whose products configure those services. Even strong performers like Salesforce—a Rule-of-40 company with the largest AI revenue line in its category, retiring 10% of its shares through a $25 billion（約4兆円） buyback—are being sold down on cannibalization fears.

What to watch

Until these companies can prove that AI revenue scales faster than it erodes the legacy subscription base, software may remain under pressure even when the rest of tech, especially chip stocks, is celebrating.
