Judge Refuses to Dismiss DRAM Price-Fixing Suit Over HBM Shift

Why the DRAM price-fixing lawsuit survived dismissal

Samsung, SK Hynix, and Micron control more than 91% of global DRAM revenue. In federal court, they argued that recent memory price spikes were simply the natural consequence of soaring artificial intelligence demand and conscious parallelism, pointing to a 2022 Ninth Circuit precedent known as DRAM II that tossed out an earlier pricing suit.

U.S. District Judge Noël Wise rejected that defense. In a ruling issued Nov. 14, 2026, Judge Wise found that the plaintiffs provided enough plausible evidence of coordinated behavior to survive a motion to dismiss. Unlike simple industry trends, the court pointed to irreversible actions that made little commercial sense for a company acting alone, including refusing long-term contracts for commodity RAM during record price surges, coordinating fab delays, and Micron shuttering its Crucial consumer brand in late 2025.

The court also highlighted identical customer-vetting protocols that all three chipmakers introduced in January 2026. Because these vetting systems appeared long after the initial shift to AI-oriented high bandwidth memory (HBM) was already underway, the judge dismissed the companies' claim that standard AI market dynamics explained the timing.

The true cost of the HBM pivot for consumer PCs

HBM requires roughly three to four times more wafer area per gigabyte than conventional DDR5. By aggressively moving production lines away from client hardware to satisfy enterprise server orders, the trio choked regular PC memory availability, resulting in a reported 697% price spike over an 18-month span ending in late 2025.

The supply constraints hit enterprise budgets alongside consumer builds. Even as tech giants grapple with the broader economic fallout of high compute costs, with Nasdaq losing $2.5 trillion as AI hardware stocks get crushed, the memory suppliers chose not to expand standard commodity lines. That refusal to build new capacity while prices skyrocketed formed the core of the plaintiffs' antitrust argument under Section 1 of the Sherman Act.

The court did discard some arguments. Judge Wise noted that executive remarks regarding 'supply discipline' and routine industry conference meetups were insufficient proof on their own. However, the operational lockstep proved substantial enough to advance the case to the discovery phase.

What it means for buyers and device pricing

For consumers and system integrators across North America and Europe, the decision ensures that memory pricing practices will face direct scrutiny in court through 2027. If the class action secures damages or forces operational changes, it could stop memory suppliers from abandoning consumer PC parts whenever corporate server demand spikes.

The chipmakers must submit formal answers to the court by Dec. 7, 2026, before attending a case management conference on Jan. 12, 2027. While retail RAM prices will not drop overnight, heading into discovery means internal memos, allocation logs, and correspondence from all three suppliers will finally be turned over to plaintiffs' lawyers.

With motions to dismiss behind them, Samsung, SK Hynix, and Micron now face the uncomfortable reality of discovery, where their internal allocation decisions during the height of the AI memory shortage will be laid bare.
