# DRAM Antitrust Lawsuit: RAM Prices Up 700% — Who’s Liable > Source: > Published: 2026-06-29 16:12:24+00:00 On June 25, 2026, a federal antitrust class-action lawsuit landed in the Northern District of California targeting Samsung, SK Hynix, and Micron — the three companies that control approximately 90% of the world’s DRAM supply. The suit, *Garciaguirre et al v. Samsung Electronics Co., Ltd. et al*, alleges the trio coordinated a deliberate cutback in DDR3 and DDR4 production under the cover of transitioning to High Bandwidth Memory (HBM) for AI chips — driving conventional [RAM prices up roughly 700% over four years](https://www.tomshardware.com/tech-industry/samsung-sk-hynix-and-micron-sued-over-alleged-dram-price-fixing-amid-record-memory-costs). For developers watching their hardware budgets collapse in slow motion, the lawsuit finally names who’s responsible. ## The AI Excuse That Wasn’t The lawsuit’s central argument is elegant and damning: Samsung, SK Hynix, and Micron shifted approximately 25% of global DRAM wafer capacity toward HBM production. HBM chips require double the silicon wafer area per unit of memory compared to standard DDR chips. Do the math: diverting 25% of wafer capacity to HBM removes something closer to 50% of equivalent DDR supply from the market. The plaintiffs argue the defendants “could have simultaneously expanded conventional DRAM capacity” to compensate — but didn’t, because HBM yields gross margins 3 to 5 times higher than conventional DDR. The profit motive isn’t subtle. SK Hynix recorded a 72% operating margin in Q1 2026 — an all-time record for any semiconductor company, exceeding even Nvidia’s peak margins. Samsung and SK Hynix together ran 63–67% gross margins in Q4 2025. Meanwhile, the three companies “systematically coordinated the shift to HBM and the discontinuation of DDR3 and DDR4,” [according to the complaint](https://wccftech.com/samsung-sk-hynix-and-micron-now-face-a-us-federal-class-action-lawsuit-for-colluding-to-bring-about-a-rampocalypse/). AI demand was real. The supply squeeze on conventional RAM was, plaintiffs allege, a choice. ## What Developers Actually Paid The numbers from the past 18 months tell the story. A 32GB DDR4 kit that sold for roughly $65 in October 2025 now costs approximately $220 — a 238% increase in eight months. DDR5 server RDIMMs (64GB) climbed from $255 in Q3 2025 to over $900 by Q1 2026. A development workstation that cost $2,200 in 2025 now runs $2,900, with the entire difference attributable to memory. For teams provisioning server infrastructure, a 50-server deployment that required $7,500 in RAM in early 2025 now costs $22,500 for the same configuration. The lawsuit points to Apple’s across-the-board price increases on iPad and Mac product lines as downstream evidence of the artificial supply constraint. ByteIota already covered the upstream picture when [Apple Mac prices jumped 20% as AI data centers drained RAM supplies](https://byteiota.com/apple-mac-prices-jump-20-ai-datacenters-drain-ram/). Now we know who, specifically, the plaintiffs are pointing at. ## They Did This Before What makes this DRAM antitrust lawsuit more credible than a typical speculative filing is the 2005 precedent. Samsung pleaded guilty to the US Department of Justice for manipulating DRAM prices between 1999 and 2002, paying a $300 million fine. SK Hynix pleaded guilty as well and paid $185 million. Multiple executives from both companies went to prison. Combined penalties across all defendants in that scandal exceeded $731 million. The current complaint explicitly invokes this history to establish a pattern of collusive behavior. In legal terms, prior bad acts evidence is powerful. These aren’t companies with clean records fighting a speculative allegation — they’re convicted repeat offenders operating in the same market, using a new justification. The “HBM transition” cover story replaces the previous era’s capacity coordination, but the alleged mechanism is structurally identical: [control supply, watch prices rise, collect the margin](https://en.sedaily.com/international/2026/06/29/samsung-sk-hynix-micron-sued-in-us-over-memory-price-fixing). ## Don’t Wait for the Verdict Antitrust cases move slowly. The previous DRAM price-fixing litigation took roughly three years from filing to resolution. Even an eventual settlement won’t reset prices in 2026. Jefferies forecasts an additional 40–50% increase in Q3 2026, followed by another 30–40% in Q4. [Micron has signaled constrained supply through at least 2028](https://wccftech.com/memory-ddr5-ddr4-shortages-last-till-q4-2027-higher-prices-throughout-2026/). The lawsuit may eventually deliver justice or a settlement fund; it won’t deliver affordable RAM this year. The practical guidance is to treat this as a cost reality, not a temporary blip. Lock in memory procurement contracts now if your team is planning server deployments in the next 12 months. High-density modules — 64GB and 128GB RDIMMs — face the worst pressure and the longest lead times. Build memory costs into 2026–2027 infrastructure budgets at today’s prices, not 2024 prices. The lawsuit is worth following, but it shouldn’t change how you plan your hardware spending. ## Key Takeaways - Samsung, SK Hynix, and Micron face a federal antitrust class-action filed June 25, 2026, alleging coordinated DDR production cuts disguised as an HBM transition drove a 700% RAM price increase since 2022 - The alleged mechanism: shift 25% of wafer capacity to higher-margin HBM, reducing DDR supply by roughly 50% equivalent, while collecting 3–5x the margin per wafer - All three defendants have prior history — Samsung and SK Hynix both pleaded guilty to DRAM price manipulation in 2005, paying a combined $485 million in fines with executives imprisoned - Prices are not coming down soon: analysts project further increases through Q3 and Q4 2026, with relief expected no earlier than 2027–2028 - Practical response: lock in procurement contracts now, budget at current prices, deprioritize large memory upgrades until market stabilizes
