Samsung, SK Hynix, and other manufacturers have redirected 70% to 90% of their advanced-node capacity toward higher-margin HBM, continuously squeezing the supply of commodity DRAM, which has quadrupled in price over three quarters. The plaintiffs argue that this conduct goes beyond normal capacity allocation and allege collusion on pricing in the commodity DRAM market. This marks the first collective legal action initiated by end-users against leading memory manufacturers in the current AI boom.
The AI-driven memory supercycle is fueling an unprecedented showdown across the supply chain. Recently, U.S. consumers and small PC manufacturers jointly filed an antitrust lawsuit against Samsung Electronics, accusing it of price collusion in the commodity DRAM market.
The plaintiffs directly allege that the prioritization of HBM production capacity is strangling the supply of commodity memory—a first-of-its-kind collective legal action by end users against leading memory manufacturers amid the AI boom.
Samsung and SK Hynix have redirected 70% to 90% of their advanced-node production capacity toward the more profitable HBM segment, continuously squeezing commodity DRAM supply and driving prices up fourfold over three quarters. Plaintiffs argue this conduct goes beyond normal capacity allocation and constitutes de facto price coordination shielded by surging AI demand.
This is not an isolated signal. From Apple and Dell announcing price hikes due to soaring memory costs—each seeing their stock prices drop over 5% in a single day—to Micron surpassing NVIDIA with an 84.9% gross margin, signing 16 long-term agreements with price floors, and collecting $22 billion in customer deposits, the costs of the memory supercycle are cascading down the supply chain.
Now, consumers and small-to-midsize PC vendors at the very end of the chain have turned to legal recourse.
Capacity 'Crowding-Out': From Market Phenomenon to Legal Allegation
The intensity of the current memory price surge far exceeds that of traditional cycles. Contract prices for commodity DRAM from the top three manufacturers were revised upward by over 100% for Q1, followed by notices from Samsung and SK Hynix of approximately 40% DDR5 price increases for Q2.
According to TrendForce, Q2 DDR5 contract prices are projected to rise 58% to 63% quarter-over-quarter, while NAND flash contract prices are expected to increase 70% to 75%—marking one of the steepest single-quarter gains in nearly a decade.
On the other side of these prices lies historic profitability upstream. Micron reported quarterly revenue of $41.456 billion, up 73.7% quarter-over-quarter; its gross margin surged from 39% a year ago to 84.9%, surpassing NVIDIA. Samsung’s operating profit for Q2 rose nearly 19-fold year-over-year. Meanwhile, inventory levels among the top three manufacturers stand at just about four weeks—far below the healthy range of eight to twelve weeks.
The plaintiffs’ core allegation is that the shift toward HBM capacity represents a form of tacit price coordination by memory makers, using AI demand as cover. Samsung and SK Hynix have allocated 80% to 90% of their advanced capacity to HBM, while Micron has redirected roughly 70% toward HBM and premium DDR5, systematically constraining supply of commodity DRAM.
The combined capital expenditures of the three major manufacturers are expected to reach USD 53.5 billion in 2026, but nearly all new capacity will be allocated exclusively to high-end product lines.
Supply Chain Dislocation: Who Will Pay for the AI Memory Boom?
Micron’s long-term agreement structure clearly reveals the current asymmetry in supply and demand. Sixteen non-cancellable strategic customer agreements cover 20% of its DRAM capacity and one-third of its NAND capacity, establishing a high-profit price floor that corresponds to approximately USD 100 billion in minimum revenue.
Customers have paid USD 22 billion in cash deposits—effectively locking in high-priced supply with real money, costs that will ultimately be passed down the supply chain to end consumers.
Apple and Dell announced price increases due to rising memory costs, with both companies’ stock prices falling by more than 5% in a single day. The impact of memory price hikes has now permeated all levels—from large OEMs and mid-sized PC manufacturers down to end consumers.
For smaller and mid-sized PC makers lacking pricing power, this upstream boom has become an unbearable cost crisis.
Antitrust Tail Risk: The Legal Variable in the Memory Super-Cycle Narrative
Class-action lawsuits carry unique deterrent power within the U.S. antitrust framework. Plaintiffs typically seek treble damages, and once discovery begins, internal documents from Samsung, SK Hynix, and other manufacturers regarding pricing decisions and capacity allocation will face judicial scrutiny.
The industry-wide spillover effects of such litigation cannot be ignored. The memory super-cycle narrative rests on the expectation of sustained supply tightness beyond 2027; if antitrust reviews prompt regulators to intervene in capacity allocation practices, the legal boundaries of memory pricing authority could be redrawn.
For investors, this lawsuit represents a tail risk that should not be overlooked within the high-expectation narrative surrounding the memory market.
Amid the frenzy of DRAM prices quadrupling over the past three quarters and Micron’s gross margin approaching 85%, a lawsuit filed by end consumers and small and medium-sized enterprises has served as a reminder to the market: on the flip side of pricing power lies mounting legal and regulatory risk. Samsung has become the first target—but certainly not the last.
