Memory Price Surge Sparks U.S. Class Action Against Three Major Producers

DRAM is a critical component in computers, smartphones and AI servers, and the market has long been dominated by Samsung, SK hynix and Micron. As AI infrastructure crowds out conventional memory capacity and supply shortages drive up prices, rising costs for finished products have prompted consumers to question whether the producers are exploiting their oligopoly to manipulate supply, drawing scrutiny to pricing and antitrust concerns.

Consumers recently filed a class-action lawsuit in the United States against Samsung, SK hynix and Micron, accusing them of jointly restricting DRAM supply, pushing prices to record highs and earning excessive profits. As of July 20, 2026, no specific damages claim or formal filing date had been disclosed. The three companies said they were expanding production lines to meet AI demand, but the additional capacity is unlikely to ease the supply-demand gap in the near term.
