Chipmaking and artificial intelligence-related stocks across Japan and Taiwan surged on Tuesday, mirroring the overnight rally in U.S. chipmaker AMD (NASDAQ:AMD) after the company struck a multi-year deal to supply AI processors to OpenAI.
Taiwan Semiconductor Manufacturing Co. (TSMC) (TW:2330), the world’s largest contract chipmaker, gained 2.5% in Taipei trading, while electronics giant Hon Hai Precision Industry Co. Ltd (TW:2317), better known as Foxconn, added 1.1%. The rally reflected growing optimism in Asia’s semiconductor sector, which plays a central role in global AI hardware production.
In Japan, major chip stocks saw solid gains, with Renesas Electronics Corp. (TYO:6723), Tokyo Electron Ltd. (TYO:8035), and Advantest Corp. (TYO:6857) climbing between 0.5% and 4%. Tech conglomerate SoftBank Group Corp. (TYO:9984), a notable investor in OpenAI, rose nearly 3%, while electronics manufacturers Ibiden Co. Ltd (TYO:4062) and Nikon Corp. (TYO:7731) advanced over 1% each.
Meanwhile, markets in mainland China, Hong Kong, and South Korea were closed for holidays, leaving the focus on Japanese and Taiwanese tech movers.
AMD’s shares surged nearly 24% in overnight trading after announcing its landmark deal with OpenAI, which includes a long-term supply agreement for AI processors and an option for OpenAI to acquire up to 10% of AMD’s equity. Analysts project the agreement could generate tens of billions in annual revenue, further fueling investor enthusiasm for AI-linked semiconductor firms.
The deal underscores the rapidly expanding demand for advanced computing power in the AI industry, highlighting Asia’s critical position in the global chip supply chain. Companies like TSMC and SK Hynix Inc. (KS:000660) are expected to remain vital suppliers as AI-driven demand continues to accelerate worldwide.
