AI Fears Rattle Markets

The Signal · 2026-07-24

Wall Street just put a price on its doubts. The Magnificent 7 shed nearly 800 billion dollars in value as oil jumped to 100 dollars a barrel. Semafor ties the selloff to Iran war fears and growing pessimism about heavy AI spending.

Also today: Lawmakers are preparing an AI Kill Switch Act that would let the Department of Homeland Security order companies to throttle or shut down their systems.

TechCrunch reports OpenAI and Anthropic guardrails are blocking offensive security researchers who hunt vulnerabilities and build exploit tools.

That's today's Signal. Thanks for watching.
