CNBC Daily Open: Micron steals Nvidia's margin king crown - CNBC

In a significant development within the semiconductor industry, Micron has overtaken NVIDIA and Meta to claim the title of Wall Street's new 'margin king,' driven by a remarkable gross margin of 84.9%... Read original →

Micron’s 84.9% gross margin isn’t just a financial milestone—it’s validation that AI infrastructure has turned high-bandwidth memory into a strategic bottleneck. Technically, this accelerates co-packaging of sub-3nm logic with HBM3E/4, pressuring TSMC, Samsung, and SK Hynix to boost TSV and hybrid bonding yields. On compliance, U.S. export controls are forcing Micron to shift capacity to Japan and India, inflating capex, while SK Hynix’s $29.4B Nasdaq listing faces CFIUS scrutiny over its Xi’an fab in China. NVIDIA may counter by vertically integrating HBM or locking in Samsung supply, while Qualcomm leverages AI CPUs to encroach on memory-intensive workloads. Over the next 18 months, the memory market will bifurcate: only players mastering EUV and advanced packaging capture premium margins; standard DRAM vendors drown in commoditization. Geopolitics has redefined memory—from cyclical commodity to national-security asset.
