how much of the ram pricing is due to collusion among manufacturers

The current surge in RAM pricing is driven by a combination of extreme market forces and supplier behavior characteristic of an oligopoly, though direct evidence of collusion is limited to legal allegations. The global memory chip market is highly concentrated, with Samsung, SK Hynix, and Micron controlling approximately **93% of the supply** [18, 19]. This market structure is currently being tested by an unprecedented demand shock from the AI sector for High-Bandwidth Memory (HBM) [1, 11]. The scale of this demand is significant enough to create a supply crisis across the entire electronics industry; for instance, OpenAI alone reportedly secured an estimated 40% of global DRAM production in late 2025 . This AI-driven consumption of fabrication capacity creates a zero-sum game, diverting resources away from consumer-grade memory and leading to severe shortages and price hikes for PCs, smartphones, and gaming consoles [1, 17].

While market fundamentals explain the price pressure, the behavior of the three dominant manufacturers has led to allegations of anticompetitive practices. A class-action lawsuit filed in California explicitly accuses Samsung, SK Hynix, and Micron of conspiring to operate a price-fixing cartel to inflate consumer prices [6, 23]. This allegation is fueled by the manufacturers' public reluctance to significantly expand production capacity despite soaring demand and prices [1, 21, 26]. The companies cite the high costs, long lead times of over two years, and a strategic fear of being caught with overcapacity if the AI boom proves to be a bubble—a concern echoed by industry analysts who note the sector's historical volatility . This collective hesitation, whether independently rational or coordinated, is the primary reason the shortage is expected to persist until at least 2026-2027 .

The distinction between explicit collusion and parallel, risk-averse behavior in an oligopoly is difficult to determine from available information. Some analysis suggests that in a cyclical industry, game theory would predict manufacturers will eventually add too much capacity, leading to future price declines . However, in the current environment, their constrained output grants them significant pricing power . The impact is a severe "tax" on the broader technology ecosystem . For example, Micron has reportedly quadrupled prices in a single year , and Apple is said to be paying a **230% premium** for memory chips in its upcoming iPhones . This price volatility makes it difficult for companies like Razer to set final prices for their products [5, 16, 20], while firms like Dell and Lenovo may resort to shipping devices with less RAM . The crisis is severe enough that it has constrained server shipments and erased billions in market value for companies like Nintendo over concerns about future component costs [10, 12].
