Storage-chip names have tumbled more than 20% in recent weeks after peaking in
late June, industry participants said. Meta’s sale of compute capacity stoked
fears of excess compute and triggered a sectorwide pullback; SanDisk, Micron,
Seagate and Western Digital are among leaders down over 20%. Traders note the
industry’s long-standing cycle—capacity broadside expansion in booms, price
collapses and industrywide losses, then capex retrenchment and eventual
recovery—remains intact. Analysts say the key variable now is whether technical
gaps between AI large models continue to narrow, which would materially affect
incremental storage demand. Separately, commercial dynamics are shifting: cloud
providers and AI data centers are increasingly signing three- to five-year
supply agreements with price bands, minimum purchase commitments and customer
deposits to secure critical supply, replacing shorter-term, spot or quarterly
contracting.
