Samsung, SK Hynix, and Micron Face Lawsuits Over Alleged RAM Supply Manipulation

Samsung, SK Hynix, and Micron, which collectively dominate the global DRAM market, are facing a U.S. class action lawsuit over allegations of supply manipulation that drove memory prices up by as much as 700% over the past four years.

The lawsuit, filed on June 25, 2026, alleges the three companies coordinated to limit DDR3 and DDR4 production while shifting capacity to the more profitable HBM memory for artificial intelligence (AI), creating an artificial shortage in the consumer market.

Key Takeaways

• Samsung, SK Hynix, and Micron face a class action lawsuit over alleged DRAM supply manipulation.
• The shift toward HBM for AI allegedly triggered a DRAM shortage and higher prices.
• The impact is expected to drive up the prices of Macs, Xbox consoles, and RAM.

Samsung, SK Hynix, and Micron Face Lawsuits Over Alleged RAM Supply Manipulation

Three global semiconductor giants, Samsung Electronics, SK Hynix, and Micron Technology, were sued in a class action in the US District Court for the Northern District of California on June 25, 2026.

The lawsuit, numbered 3:26-cv-06345, accuses the three companies of coordinatedly restricting the supply of conventional DRAM to raise prices, using the surge in AI demand as justification.

With nearly 100% control of the global DRAM market, the three companies are accused of oligopolistic practices that harm consumers and small businesses.

What is the content of the lawsuit?

The plaintiffs, consisting of 14 individual consumers and three small PC assembly businesses, accuse Samsung, SK Hynix, and Micron of systematically restricting DRAM supplies since 2022.

As a result, conventional DRAM prices jumped about 700% in four years.

The lawsuit calls this increase "mind-blowing scale and rapidity."

The essence of the accusation:The three companies are simultaneously reducing production of DDR3 and DDR4, the types of RAM widely used in PCs, laptops, and game consoles, while shifting factory capacity to HBM (High-Bandwidth Memory) which is more profitable for AI data centers.

The plaintiffs argue that in a competitive market, at least one company should have increased DDR production to gain market share when prices rose, but that did not happen.

Why Is This Allegation Serious?

The uniqueness of the DRAM market lies in its oligopolistic structure.

These three companies control nearly the entire global supply, and building a new DRAM factory costs tens of billions of dollars and takes years.

As a result, when all three restrict supply simultaneously, no new players can enter to lower prices.

As the lawsuit states: "when three companies restrict supply, no outside party can expand production to compete with them."

This is not the first time the three companies have faced similar allegations.

In 2005, Samsung paid a $300 million fine and SK Hynix $185 million after pleading guilty to a DRAM price-fixing conspiracy.

Micron escaped punishment at that time by becoming a whistleblower witness.

China also investigated the three when prices soared between 2016-2018.

Impact on Consumers

The lawsuit comes at a time when global consumers are feeling the pressure of rising prices.

Apple raised prices on MacBooks and iPads by up to 20% on the same day the lawsuit was filed, triggering a 6% stock drop.

Microsoft raised Xbox prices by $100-$150, citing memory costs that have increased "more than 2.5 times."

Valve, Sony, and Nintendo also raised the prices of their hardware.

Micron itself has acknowledged a structural shift in its business model, signing 16 strategic agreements worth $22 billion with hyperscale AI customers.

This shows how DRAM supply is prioritized for AI over general consumers.

RAM Company Prospects and Responses

The plaintiffs are asking the court to stop the supply restrictions and award treble damages under US antitrust law.

If the court recognizes class-action status, the group of plaintiffs could expand to include consumers and businesses that purchased products containing DRAM since 2022.

Micron has denied the allegations, stating that "we compete strictly, fairly, and in compliance with all applicable laws." Samsung and SK Hynix are also reportedly reviewing the lawsuit and will respond through legal procedures.

Meanwhile, analysts expect DRAM prices to rise by up to 50% in Q3 2026 and another 30-40% in Q4, as AI demand continues to consume available production capacity.

SK Group Chairman Chey Tae-won even called memory the “fuel” of the AI ​​era, signaling the shortage may continue.

Conclusion

The lawsuits against Samsung, SK Hynix, and Micron highlight consumer vulnerability in a market dominated by a handful of players.

Whether the allegations of supply manipulation are proven or simply a reflection of an AI demand imbalance, one thing is certain: soaring RAM prices have fundamentally changed the consumer electronics landscape.

The court's decision in this case will set an important precedent for the global semiconductor industry.
