Micron faces price-fixing lawsuit, raising antitrust scrutiny on memory chip pricing practices.
Artificial intelligence has created shortages across nearly every part of the semiconductor supply chain. While GPUs have received most of the attention, memory chips have quietly become equally critical. Every advanced AI accelerator depends on high-bandwidth memory (HBM), and manufacturers are struggling to keep pace. Even after investing billions of dollars to expand production, suppliers remain sold out months in advance.
Despite the AI boom, some view the situation more skeptically. Micron Technology, SK hynix, and Samsung now stand accused of colluding to keep prices high in a new lawsuit seeking class-action status, filed in California federal court. As this isn't the first time the memory market has faced price-fixing allegations, the question becomes whether history is repeating itself or whether this simply reflects basic economics.
The lawsuit alleges that Micron, Samsung, and SK hynix—which collectively control roughly 90% of the global memory market—coordinated production cuts of older DDR3 and DDR4 memory while steering customers toward higher-priced HBM products. The complaint points to recent price increases for Apple's Mac and iPad products as evidence that consumers ultimately bear the cost.
These allegations echo the industry's infamous DRAM price-fixing scandal from the early 2000s. Following complaints by Dell Technologies and Gateway, investigations found that Micron, Samsung, SK hynix, Infineon, and Elpida (now owned by Micron) had coordinated DRAM pricing. Several companies, including Micron, ultimately pleaded guilty and paid criminal fines, while numerous civil settlements followed.
History makes today's accusations difficult to dismiss. However, courts have consistently ruled that an oligopoly alone is insufficient proof of illegal collusion. Plaintiffs generally must establish "plus factors" beyond parallel pricing—such as direct communications, coordinated production decisions, or other evidence showing companies acted together rather than independently.
A simpler explanation may account for the situation. When demand grows faster than supply, prices increase until additional capacity comes online or new competition emerges, allowing equilibrium to be reached. If customers are competing for products already sold out, rising prices align with basic economic principles.
Micron's own earnings releases show demand outstripping available HBM supply by a wide margin. AI infrastructure spending from hyperscalers continues climbing, with some $750 billion expected from major players alone, while expanding memory fabrication plants requires years—not months—and billions of dollars in capital expenditures. Micron's HBM production is fully sold out for 2026 under binding, fixed-price, multi-year contracts, with a significant portion of 2027 output also committed. Management has stated it can satisfy only approximately 50% to 66% of customer demand despite running manufacturing facilities near full utilization while attempting to expand capacity.
This situation is not unique to Micron. Both Samsung and SK hynix face similar constraints as AI server demand continues climbing. Producing advanced HBM stacks requires new manufacturing techniques, advanced packaging, and years of capital investment. Capacity cannot be doubled overnight.
The new lawsuit revives memories of the industry's genuine price-fixing scandal two decades ago, and regulators should investigate credible allegations wherever they arise. Regardless, today's market appears fundamentally different. AI has created unprecedented demand for HBM memory while production remains constrained despite aggressive capacity expansion. Until plaintiffs produce evidence beyond parallel pricing in a concentrated industry, this case appears to reflect the basic laws of supply and demand more than a repeat of the DRAM conspiracy that led to guilty pleas in 2002.
