US AI stock sell-off shakes markets from Wall Street to Asia
TL;DR
A sell-off in US AI stocks dragged global markets lower on Tuesday as investors reassessed stretched valuations and heavy AI infrastructure spending. The Nasdaq dropped 2.2 percent, the S&P 500 fell 1.43 percent, while the Dow was comparatively steady. Chipmakers and major tech companies were in focus because they have powered much of the recent market rally. Market attention shifted from geopolitical risk around the US-Iran conflict toward whether the AI boom can justify its price tag.
Nauti's Take
The party turns fast when AI fantasy becomes a capex invoice. For builders, the message is blunt: GPU volume, model size, and pitch-deck momentum are not a moat.
Margins, lock-in, and real workflow value now get interrogated.
Briefingshow
The drop shows how dependent the current rally has become on a small group of AI and chip stocks. Once investors start pricing in power costs, data centers, capex and uncertain returns, AI optimism can quickly turn into a broader valuation reset.
