Korea's July experience is arriving elsewhere on a delay.
The concern that hit Korean retail investors — whether AI capital expenditure translates into returns — surfaced globally over the past week after Anthropic CEO Dario Amodei called for the industry to slow development, with Sam Altman and Elon Musk agreeing.
SK Hynix dropped 6% on that news and the Kospi fell 3% in a single session. The Philadelphia Semiconductor Index fell 5.9% in its worst session since July 1, with Micron and SanDisk each losing more than 7%.
Nvidia guided third-quarter gross margin to 74% from 75% — the first sequential decline of the cycle — citing memory costs, power, land and data center infrastructure.
Korea's market, concentrated in memory producers supplying AI infrastructure, registered that shift months before the US equivalents did.
