Chipmakers worldwide tacked on more than $200 billion in market value as investors piled into anything tied to artificial intelligence. The gains followed headlines including OpenAI’s employee tender valuing the startup at about $500 billion and reported talks that could see Intel add AMD as a foundry customer. South Korean names led in Asia—SK Hynix jumped 10% and Samsung rose 3.5%, lifting the Kospi to a record—while Europe’s ASML climbed as much as 4.9%, extending a roughly 50% rebound from its August trough. Valuations are stretching: Bloomberg’s Asia chip gauge trades near 19 times forward earnings and the PHLX Semiconductor Index around 27 times, nearing 2024 highs. Analysts say FOMO is eclipsing bubble worries, though fourth-quarter results may test the momentum. Investors continue to crowd into AI infrastructure providers, pushing up leaders from Nvidia to memory and equipment suppliers.
