Why I'd Rather Own Micron Stock Than Sandisk - The Motley Fool

In recent months, memory chip stocks have surged due to a significant shortage driven by AI demand. Micron and SanDisk are two major beneficiaries, but the author prefers Micron over SanDisk. While Sa... Read original →

The AI compute arms race is restructuring the memory chip stack. Micron’s IDM model grants it control over EUV-based DRAM and HBM production, securing premium contracts with NVIDIA and AMD while leveraging CHIPS Act subsidies for onshore capacity—creating a tech-policy moat. In contrast, SanDisk (under Western Digital) lacks manufacturing leverage; its fabless structure offers no hedge against NAND volatility and zero presence in HBM—a critical AI interface. Samsung and SK Hynix are already racing toward HBM4, and without breakthroughs in 3D NAND stacking yields, SanDisk risks exclusion from AI supply chains. Within 18 months, U.S. export controls on advanced memory manufacturing could tighten, favoring firms with domestic fabs. Micron’s vertical integration positions it as a structural winner in tech geopolitics, while pure-play NAND vendors face repeat of 2019-style margin collapse.
