Which Hot Growth Stock Is The Better Buy Right Now: Micron or SpaceX? - Yahoo Finance

In June 2026, the tech stock market once again focuses on two highly talked-about companies: Micron Technology and Space Exploration Technologies (SpaceX). Micron’s stock has surged over 9x in the pas... Read original →

Micron’s 9x stock surge reflects a structural shift in AI-driven memory demand, not speculation. With HBM4 ramping up, its reliance on EUV layers and 3nm-class TSV packaging is forcing the entire semiconductor equipment and materials ecosystem to accelerate upgrades—TSMC’s CoWoS capacity is already a bottleneck. Geopolitically, as the only U.S.-headquartered DRAM leader, Micron benefits from CHIPS Act subsidies and export controls, while Samsung and SK Hynix face higher compliance costs for their fabs in Xi’an and Wuxi. Though Samsung leads in HBM3E yields, Micron’s deep integration with NVIDIA and xAI grants it influence over AI cluster memory standards. Over the next 18 months, as AI server memory exceeds 50% of data center TAM, Micron will transition from a cyclical memory vendor to a core AI infrastructure provider—unlike SpaceX, whose 125x P/S ratio lacks cash flow backing and whose AI ambitions remain conceptual.
