Wall Street 'Chip-Wreck' Triggers AI Bubble Fear

What happened

Major tech stocks tumbled on June 23: Nasdaq 100 -3.3%, the chip gauge slid ~8%, and South Korea's Kospi fell 10% from a record, as markets openly questioned the sustainability of the AI-fueled bull run.

Context and impact

It follows Morgan Stanley's $570B AI-debt issuance forecast for 2026, hyperscaler capex projected above $1T by 2027, and a string of mega financings (Anthropic $65B Series H at $965B, OpenAI pre-IPO $730B). The first big signal that the cost of the buildout may outpace the returns.
