The AI-driven memory supercycle is fueling an unprecedented confrontation within the supply chain. Samsung Electronics is now facing a class-action antitrust lawsuit in the United States, filed by consumers and small PC manufacturers who accuse the company of colluding on prices in the general-purpose DRAM market.
The plaintiffs allege that the shift in production capacity towards High Bandwidth Memory (HBM) is suffocating the supply of standard memory—marking the first collective legal action by end-users against a leading memory chipmaker since the AI boom began.
Manufacturers like Samsung and SK Hynix have redirected 70% to 90% of their advanced production capacity to the more profitable HBM, persistently squeezing the supply of general-purpose DRAM and driving prices up fourfold over the past three quarters. The plaintiffs contend this behavior goes beyond normal capacity allocation, constituting a de facto price coordination "shielded" by AI demand.
This is not an isolated signal. The costs of the memory supercycle are cascading down the entire supply chain. This is evident from Apple and Dell announcing price hikes due to rising memory costs, with their stock prices each falling over 5% in a single day, to Micron achieving an 84.9% gross margin—surpassing Nvidia—and securing 16 long-term agreements with price floors backed by $22 billion in customer deposits.
Now, consumers and small-to-medium PC manufacturers at the end of the chain are turning to legal recourse.
The "Crowding Out" Effect: From Market Phenomenon to Legal Claim
The intensity of the current memory price surge far exceeds typical cyclical patterns. The three major memory makers have revised their Q1 general-purpose DRAM contract price increases to over 100%, with Samsung and SK Hynix subsequently issuing notices for a roughly 40% price hike on DDR5 in Q2.
According to TrendForce data, 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 a single-quarter surge rarely seen in the past decade.
On the other side of these prices is a historic profit explosion for upstream suppliers. Micron's latest quarterly revenue reached $41.456 billion, a 73.7% sequential increase; its gross margin jumped from 39% a year ago to 84.9%, surpassing Nvidia. Samsung's Q2 operating profit surged approximately 19-fold year-over-year. The three major suppliers hold inventory for only about 4 weeks, well below the healthy level of 8 to 12 weeks.
The core of the plaintiffs' accusation is that the HBM capacity shift is a disguised form of collusive pricing by memory makers, using AI demand as cover. Samsung and SK Hynix are allocating 80% to 90% of their advanced capacity to HBM, while Micron is directing about 70% to HBM and high-end DDR5, systematically compressing the supply of general-purpose DRAM.
The combined capital expenditure of the three major suppliers is forecast to reach $53.5 billion by 2026, with nearly all new capacity locked in for high-end product lines.
Supply Chain Fracture: Who Bears the Cost of the AI Memory Boom?
The structure of Micron's long-term agreements clearly reveals the current asymmetry in supply and demand. Sixteen non-cancellable strategic customer contracts cover 20% of its DRAM capacity and one-third of its NAND capacity, setting high-profit price floors that guarantee a minimum revenue of approximately $100 billion.
Customers have paid $22 billion in cash deposits—essentially locking in high-price supply with real money—and these costs are ultimately being passed down the chain to end consumers.
Apple and Dell have announced price increases due to rising memory costs, with both companies' stocks falling over 5% in a single session. The shockwave of memory price hikes has penetrated every level, from large OEMs to small and medium PC makers and finally to end consumers.
For small and medium PC manufacturers with limited bargaining power, this "upstream狂欢" (狂欢 translates to 'carnival' or 'frenzy' but is used here to imply the suppliers' profit surge) has become an unbearable cost disaster.
Antitrust Tail Risk: A Legal Variable in the High-Growth Memory Narrative
Class-action lawsuits hold particular deterrence within the US antitrust system. Plaintiffs typically seek treble damages, and if the case proceeds to the discovery phase, internal documents related to pricing decisions and capacity allocation from Samsung, SK Hynix, and others would face judicial scrutiny.
The industry-wide spillover effects of the lawsuit cannot be ignored. The narrative of a memory supercycle is built on expectations of tight supply lasting beyond 2027. If antitrust scrutiny prompts regulators to intervene in capacity allocation practices, the legal boundaries of memory pricing power could be redrawn.
For investors, this lawsuit represents a tail risk variable that should not be overlooked in the otherwise bullish memory story.
Amid the frenzy of DRAM prices quadrupling over three quarters and Micron's gross margins nearing 85%, a lawsuit filed by end-consumers and small businesses serves as a reminder: the flip side of pricing power is the accumulation of legal and regulatory risks. Samsung may be the first target, but it is unlikely to be the last.
