Samsung, SK Hynix, Micron Face Antitrust Class Action Lawsuit

Plaintiffs say the three chipmakers control about 90% of the DRAM market and shifted 80% of capacity to higher-margin AI memory.

  • A group of individuals and small businesses launched a class action lawsuit against Samsung, Hynix, and Micron, accusing the memory makers of price-fixing and market manipulation under the Sherman Act.
  • These firms control around 90% of the global DRAM market, and after OpenAI CEO Sam Altman signed an IOU for memory, they shifted around 80% of manufacturing capacity to high-margin HBM for data centers.

  • Cloud hyperscalers like Microsoft, Google, and Amazon bought up the majority of extra capacity, leaving the average Joe without relief in RAM pricing until at least 2028.
  • The case against Samsung, Hynix, and Micron hangs on "well, they've done it before" energy, though tech giants may use the memory build-out as a defense if plaintiffs lack a smoking gun.
