Micron, Samsung, SK Hynix Sued Over Alleged DRAM Price Fixing
A US class-action lawsuit accuses Micron, Samsung, and SK Hynix of restricting DRAM supply to artificially inflate prices amid the AI demand surge.
A private class-action lawsuit filed in the United States on June 29 accuses Micron Technology (NASDAQ: MU), Samsung, and SK Hynix of conspiring to restrict the supply of DRAM memory chips in order to drive up prices, according to court filings. The complaint targets three of the world's dominant memory chipmakers at a moment when demand for high-bandwidth memory tied to artificial intelligence infrastructure has sent DRAM prices sharply higher.
The lawsuit alleges that the companies coordinated supply constraints rather than allowing market forces to set pricing — a claim that, if proven, could expose the defendants to significant antitrust liability. DRAM chips are a foundational component in servers, data centers, and consumer electronics, meaning artificially elevated prices would ripple across the broader technology supply chain.

Micron has drawn considerable attention from institutional investors in recent months, with billionaire Philippe Laffont among those identifying it as a top AI-era holding. That bullish sentiment reflects surging demand for advanced memory from AI model training and inference workloads — the same demand environment that plaintiffs argue the chipmakers exploited through supply manipulation.
The outcome of the litigation could carry wide implications for the semiconductor industry, particularly as governments in the US, Europe, and Asia scrutinize chip market concentration. Antitrust actions in the DRAM sector are not unprecedented — major memory makers reached settlements in similar US price-fixing cases in the mid-2000s. Whether the current lawsuit advances past preliminary legal hurdles remains to be seen.
