Yahoo FinanceInside the History of DRAM Price-Fixing Lawsuits and the Impact of HBM Allocations
In late June, 17 plaintiffs filed a lawsuit in the U.S. District Court for the Northern District of California against Samsung, SK hynix, and Micron, alleging the three companies, which control roughly 90% of the global DRAM market, coordinated supply restrictions that pushed memory prices up around 700% in four years. This is the third major legal assault on the DRAM industry in two decades. The first case ended in criminal guilty pleas and over $730 million in fines; the second case collapsed in 2020. The new case must clear the same legal barrier set by the Supreme Court's 2007 Twombly decision, which requires factual allegations making an actual agreement plausible, not just parallel conduct. Plaintiffs now allege the three memory makers used their pivot to high-bandwidth memory (HBM) as a pretext to cut commodity DRAM output. The article notes each allegation has a non-conspiratorial explanation, making dismissal likely.

Yahoo FinanceMicron and Memory Makers Sued Over DRAM Price Fixing; Analyst Calls It Headline Risk
A class-action lawsuit filed on June 25, 2026, in a U.S. court accuses Micron Technology, Samsung Electronics, and SK Hynix of conspiring to fix DRAM prices by cutting production of older DDR3 and DDR4 chips while shifting focus to AI-focused High Bandwidth Memory (HBM). The lawsuit alleges this was done to artificially raise prices, noting DRAM prices have surged about 700% since 2022. The article argues this is primarily headline risk for Micron (MU) stock, given the company's strong fundamentals: record Q3 2026 revenue of $41.46 billion, nearly 4x year-over-year growth, and a forward P/E of 18.40 below the sector average. Micron's growth drivers remain intact, including a partnership with Anthropic and domestic expansion of 1-alpha DRAM production in Virginia. The stock slipped to $1,023.65 on the news but has gained 842% over the past 52 weeks.
Yahoo FinanceMicron Hit With Price-Fixing Lawsuit: Real Collusion or Simple Supply and Demand?
A new class-action lawsuit filed in California federal court accuses Micron Technology, Samsung, and SK hynix of colluding to artificially inflate memory chip prices by coordinating production cuts of older DDR3 and DDR4 memory while steering customers toward higher-priced HBM products. The three companies control roughly 90% of the global memory market. The lawsuit cites recent price increases for Apple's Mac and iPad products as evidence consumers bear the cost. However, Micron's HBM is sold out through 2026, meeting only 50-66% of demand, suggesting genuine scarcity. The memory industry has a history of price-fixing, with Micron and rivals pleading guilty in a 2002 DRAM scandal. Courts have ruled that oligopoly alone is not proof of collusion, requiring 'plus factors' beyond parallel pricing.

Yahoo FinanceMemory Chip Giants Samsung, SK Hynix, Micron Face US Lawsuit Over 700% DRAM Price Spike
A class-action lawsuit filed in California federal court on June 29, 2026, accuses Samsung, SK Hynix, and Micron of colluding to artificially inflate DRAM memory chip prices by up to 700% over four years. The plaintiffs—14 individuals and three small computer shops—allege the companies shifted factory production toward higher-margin AI chips, starving the market for ordinary DRAM and driving prices up. The firms control about 90% of the global DRAM market. The lawsuit revives old cartel claims: in 2005, Samsung paid a $300 million fine for price-fixing, and some executives went to prison. The plaintiffs argue the same companies, product, and some former executives are involved again. Days after the lawsuit, Samsung Group announced a $650 billion spending plan over 10 years and SK Group a similar plan, which they say proves real demand from AI. Critics remain skeptical. Micron's decision to shutter its popular Crucial brand in December 2025, just as prices peaked, also drew scrutiny. Analysts at Jefferies expect memory prices to rise 50% this quarter and 40% next, with no relief before 2028. Apple has already raised prices on some products. Previous similar lawsuits failed, but plaintiffs claim stronger evidence this time.
Yahoo FinanceMemory Chip Giants Face Lawsuit Over 700% DRAM Price Spike
A US lawsuit has been filed against the three dominant DRAM manufacturers—Samsung, SK Hynix, and Micron—alleging they orchestrated a 700% price increase over four years by shifting factory capacity toward higher-margin AI memory chips, thereby constraining supply of regular DRAM. The lawsuit, filed in California federal court, revives claims of cartel behavior dating back to a 2005 price-fixing conviction. Plaintiffs include 14 individuals and three small computer shops, represented by law firm Hagens Berman. Days after the lawsuit, Samsung and SK Group announced massive spending plans totaling approximately $650 billion, which the companies argue demonstrates real demand rather than a scheme. Micron also closed its popular Crucial brand in December, a move analysts debate. Investors reacted negatively, with Samsung stock falling 5.3% and SK Hynix dropping 3.4%. Jefferies forecasts memory prices will rise ~50% this quarter and 40% next, with no relief before 2028. Previous versions of this lawsuit failed, but plaintiffs cite the same companies, product, and executives previously convicted.
