Applied Materials (NASDAQ:AMAT) gains $50 billion as AI memory trade pushes past Street forecasts - TechStock²

On June 25, 2026, Applied Materials (NASDAQ:AMAT) surged 10.7% to $652.07, adding approximately $50.4 billion in market value, driven by stronger-than-expected AI memory trade activity. The company’s ... Read original →

Micron and Samsung’s accelerated HBM4 ramp is directly fueling demand for Applied Materials’ Centura Prime Epi and eBeam inspection tools, confirming the irreversible shift toward 1β/1γ DRAM nodes. Technically, EUV maturity in logic is now enabling advanced packaging—chiplet architectures demand tighter memory-logic integration, forcing equipment vendors to blur traditional process boundaries. Geopolitically, while U.S. export controls tighten, AMAT mitigates compliance costs via localized support in Taiwan, China, Korea, and Southeast Asia. However, Fed rate hikes could abruptly curb memory CapEx, exposing its 18.7% valuation premium. Competitors like ASML and Lam Research may counter by integrating optical metrology with etch modules to challenge AMAT’s front-end-to-mid-end HBM synergy. Over the next 18 months, HBM-driven memory equipment spending could surge from 35% to 50% of total wafer fab investments, with advanced packaging emerging as a critical second growth vector—especially as AI clusters adopt co-packaged optics.
