Nvidia and OpenAI's $100-billion deal sparks global chip stock rally (www.cnbc.com)

Nvidia announced a roughly $100 billion investment deal with OpenAI and said OpenAI plans to build and deploy Nvidia systems that would draw about 10 gigawatts of power—equivalent to roughly 4–5 million GPUs, per CEO Jensen Huang. The announcement triggered a broad chip-stock rally: TSMC jumped ~3.5%, SK Hynix rose >2.5%, Samsung gained ~1.4%, and equipment suppliers such as Tokyo Electron also climbed as investor optimism from Wall Street rippled through Asian and European markets. The scale of the project is significant for AI/ML because it implies massive, sustained demand for GPUs, high-bandwidth memory (HBM), advanced logic chips and the lithography and fab equipment that produce them. Key suppliers—TSMC (chip manufacture), memory makers (SK Hynix, potentially Samsung), and equipment vendors (ASML, Tokyo Electron, ASM/ASMI)—stand to benefit from elevated capex and long production timelines, though company-specific results (ASM’s weaker guidance) can still depress some names short term. Technically, 10 GW of datacenter power underscores infrastructure and cooling constraints as well as long lead times for chips and memory, meaning material supply-chain and investment implications for the global semiconductor ecosystem over years rather than months.
