Global chip manufacturers' market capitalization has soared as investors rush to position themselves in the artificial intelligence sector, marking the latest sign of technology stocks' continued surge to historic highs.

The industry is being swept by a wave of positive news from AI companies, including OpenAI setting a record $500 billion valuation through employee share sales and reaching agreements with multiple South Korean chip manufacturers, alongside reports that Intel is in talks to add Advanced Micro Devices Inc. to its client roster.

According to institutional calculations, this rally has propelled the combined market capitalization of the Philadelphia Semiconductor Index and Asian chip stock indices to surge by over $200 billion in the latest trading session.

Driven by OpenAI partnership news, South Korean chip stocks led gains on Thursday, pushing the Korea Kospi index to record highs. SK Hynix shares soared 10%, while Samsung Electronics climbed 3.5%.

Analysts note that this bull run is primarily driven by "fear of missing out" (FOMO) psychology, with investors largely dismissing concerns about potential bubble formation in the AI sector.

"Tech stocks show no signs of slowing momentum, as if gravity doesn't exist, headwinds are easily brushed aside, and every piece of AI news triggers euphoric sentiment," said Hebe Chen, analyst at Vantage Markets. "While bubble rhetoric persists, FOMO psychology clearly dominates the market. This rally appears self-sustaining until the upcoming fourth-quarter earnings reports potentially force markets back to reality."

Recent stock price increases have sent chip manufacturer valuations soaring: the Bloomberg Asia Chip Index currently trades at approximately 19 times expected forward earnings, while the SOX index trades at 27 times earnings, approaching the historic highs set in 2024.
