Chip stocks shed over $1 trillion as AI selloff deepens

Global semiconductor stocks lost more than $1T in market value in a single session, with Nvidia alone down $238B. SK Hynix (-$176B), Samsung (-$173B), Micron (-$113B), and AMD (-$110B) were also hit as China's chipmaking progress and circular-financing fears shake confidence in the AI boom. The selloff marks the deepest correction yet in the AI infrastructure buildout, raising questions about the sustainability of hyperscaler capital expenditure.
