On August 18, Western Digital fell 3.48% in pre-market trading, trading at $512.0/share, with turnover of $4.6231 million, as the storage chip sector experienced broad profit-taking following the prior session's sharp rally.

The pullback comes after a strong surge on August 17, when the storage sector was catalyzed by Elon Musk publicly endorsing storage as the core constraint of autonomous AI and Goldman Sachs projecting that global autonomous AI monthly token consumption will reach 120 quadrillion by 2030 — 24 times early levels. Western Digital gained over 6% and SanDisk rose over 8% in that session. The current pre-market session saw widespread selling across the sector, with SanDisk down approximately 5%, Seagate Technology down 3.38%, and Super Micro Computer down 3.61%.

Adding to bearish sentiment, Bernstein's recent analysis projects Q3 DRAM and NAND contract price increases narrowing to approximately 20%, suggesting the storage pricing upcycle may be approaching its ceiling as demand-side resistance and long-term agreement price caps compress further upside.
