The share price of Micron Technology fell as much as 9.5% on Monday, following a significant legal challenge against the dominant global producers of memory chips, with allegations of a coordinated scheme to manipulate market supply.
A group of seventeen individual and commercial plaintiffs filed the class-action complaint in the Northern District of California, targeting Samsung Electronics, SK Hynix, and Micron Technology. The suit contends that these industry leaders engaged in secret cooperation to keep standard memory components artificially scarce, thereby driving up acquisition costs for a wide range of consumers and businesses.
The financial repercussions of this alleged collusion have been severe, characterized by a nearly 700% increase in the price of conventional memory modules over the previous four-year period. According to market data cited in the litigation, this inflationary trend has had a cascading effect on the broader electronics sector.
Major hardware manufacturers, including Nintendo, Microsoft, and Sony, have reportedly increased the retail prices of their gaming consoles to offset rising component costs. Furthermore, Valve recently noted that the high expense of memory—exacerbated by the industry-wide focus on artificial intelligence—has pushed the price of its upcoming Steam Machine console beyond preferred levels.
At the center of the legal dispute is the industry’s massive pivot toward High-Bandwidth Memory (HBM) infrastructure designed for AI data centers. The plaintiffs, represented by the antitrust law firm Bathaee Dunne LLP, argue that the three companies used this transition as a tactical excuse to dismantle production lines for older, legacy formats like DDR3 and DDR4. The filing asserts that these production cuts were made in defiance of standard economic incentives, pointing specifically to Micron’s 2025 decision to terminate its profitable Crucial consumer memory division during a period of record financial performance.
Moreover, the plaintiffs highlight a historical precedent for such activities, noting that Samsung, SK Hynix, and Micron were previously convicted for their roles in a criminal conspiracy to fix memory prices between 1998 and 2002.
