If you’ve noticed laptop, tablet, and smartphone prices creeping up lately, you’re not imagining it. Behind the trend is a sharp spike in DRAM prices — and that spike has now landed the world’s three biggest memory makers in a US courtroom. Here’s a breakdown of what’s being alleged, and why it matters.
What Happened
On June 25, 2026, a class-action lawsuit was filed in the US District Court for the Northern District of California under the case name “Garciaguirre v. Samsung Electronics.” The plaintiffs are 17 in total — 14 individual US consumers and three small PC assembly/retail businesses. Their target: Samsung Electronics, SK Hynix, and Micron, the so-called “Big Three” that together control roughly 90–95% of the global DRAM market.
The case has been assigned to Judge Noel Wise. The plaintiffs are represented by Bathaee Dunne, a firm known for its win in the Google digital advertising antitrust case, and Hagens Berman, a firm with a long track record of filing DRAM price-fixing suits.
The Plaintiffs’ Argument: “HBM Was the Excuse”
The core claim is straightforward: the three companies deliberately cut back on conventional DRAM production in order to prioritize the more profitable AI-driven HBM (High Bandwidth Memory) business — and did so in a coordinated way, not independently.
The evidence cited to support this includes:
- Manufacturing line conversion ratios. At Micron, converting a wafer from DDR5 to HBM production reportedly comes at roughly a 3-to-1 trade-off — meaning every HBM unit produced effectively removes the equivalent of three units of conventional DRAM from supply.
- Simultaneous discontinuation of older products. All three companies phased out older DDR3 and DDR4 modules around the same time, even while demand for them persisted.
- Overlapping timing of production cuts. SK Hynix announced production and investment cuts in October 2022; Micron reduced wafer starts by about 20% around the same period; Samsung joined the cuts in April 2023. The complaint states that “none of the three companies took advantage of another’s pullback to increase output and capture customers — instead, all three pulled back together.”
- Micron’s exit from Crucial. The plaintiffs point to Micron winding down its consumer memory brand, Crucial, as suspicious — arguing that in a rising-price environment, maintaining a direct-to-consumer channel would normally make business sense, and abandoning it doesn’t fit a picture of independent profit-maximizing behavior.
- The OpenAI Stargate project. The complaint also references large-scale supply discussions between Samsung, SK Hynix, and the Stargate project, arguing that capacity tied up in such deals further constrained the general-purpose DRAM supply.
The numbers at stake are significant. According to the complaint, contract DRAM prices rose roughly 90% in Q1 2026 and another 60% in Q2, adding up to a cumulative increase of about 700% over four years. The scale of the spike has even earned a nickname in industry circles: the “RAMpocalypse.”
Apple Enters the Picture: Price Hikes Ripple Into Finished Products
What makes this case notable is that it doesn’t stop at the component level. Coincidentally, on the same day the lawsuit was filed — June 25 — Apple raised prices across several product lines, including Mac, iPad, Apple TV, HomePod, and parts of the Vision Pro lineup. Reports pointed to rising memory costs, not spec changes, as the driver.
- MacBook Air: $1,099 → $1,299
- MacBook Pro: $1,699 → $1,999
- iPad Air: $599 → $749
Across the Mac and iPad lineup, the increases averaged out to roughly 15–25%, and Apple said in a statement that component costs had never risen this fast or this far in such a short window — leaving the door open for further hikes.
One detail worth noting: while Samsung and SK Hynix shares rose that day on earnings optimism, Apple’s own stock actually fell about 5% intraday on the news, apparently on investor concern that the price hikes could dampen demand.
iPhone pricing hasn’t moved yet, but estimates of a future increase vary by outlet — figures anywhere from roughly $150 to $270 have been floated. Similar pressure has reportedly been building for Microsoft’s Xbox, Samsung’s Galaxy S26, Sony and Nintendo consoles, and laptops from Dell, HP, Lenovo, and Asus.
This matters for the plaintiffs’ case: the argument that rising DRAM prices are being passed straight through to everyday consumer products is central to establishing consumer harm.
But This Isn’t the First Time
Here’s the part worth keeping in perspective: nearly identical lawsuits against the same three companies were filed in 2018, 2019, and 2021 — and all of them failed.
The most recent precedent is instructive. The 2018 case was dismissed by the Northern District of California in 2020, and the Ninth Circuit Court of Appeals affirmed that dismissal in March 2022. In its ruling, the appeals court found that the eight “plus factors” the plaintiffs presented failed to supply the “something more” needed to support an inference of a price-fixing conspiracy. The court concluded that the companies’ production adjustments were better explained as “legitimate, independent pursuit of profit in a free market” than as collusion.
US antitrust law sets a high bar here. Under the Sherman Act, similar behavior across multiple companies isn’t enough on its own to prove collusion — plaintiffs need additional evidence pointing to an actual agreement. Legal observers have already noted that simply pointing to overlapping timing in the HBM transition may run into the same wall that doomed earlier cases.
That said, this complaint does introduce some new elements not present in prior suits — the Crucial exit, the Stargate project reference, and claims that the three companies cross-checked end-user demand and order volumes around January 2026. Whether these new details are enough to produce a different outcome is the central question for this case.
For context: Samsung and SK Hynix (then Hynix Semiconductor) actually pled guilty to DRAM price-fixing in the US between 1999 and 2002, paying fines of $300 million and $185 million respectively. That earlier case involved direct evidence — emails and actual agreements — which sets it apart from the current complaint, which relies on circumstantial evidence.
How the Companies Are Responding
- SK Hynix was sued the day after filing its US ADR offering paperwork, and has since amended its registration statement to list the lawsuit as an investment risk factor.
- Micron has denied the allegations and says it will defend itself vigorously.
- All three companies maintain that their shift toward HBM production reflects independent business decisions driven by surging AI demand — not coordination.
What Happens Next
The outcome of this case hinges on two key hurdles:
- Class certification — whether the court agrees to treat this as a nationwide class action representing US consumers broadly.
- Discovery — whether the plaintiffs can survive a motion to dismiss and obtain internal communications showing actual coordination on pricing or production.
There’s also a precedent for settlement: a similar case was resolved in 2006 for roughly $345 million. That leaves open the possibility this case, too, ends in a settlement rather than a final verdict.
Meanwhile, Earnings Are at Record Highs
Here’s the irony: the very dynamic the lawsuit challenges — the HBM shift and resulting supply constraints — is also what’s driving record profits at all three companies.
- SK Hynix: Q1 2026 revenue of roughly ₩52.58 trillion, operating profit of ₩37.61 trillion (a 72% operating margin)
- Samsung Electronics: Q1 operating profit of ₩57.2 trillion, up 756% year-over-year, with 94% of that coming from its semiconductor business
- Micron: Revenue of roughly $41.5 billion for the March–May quarter, about four times higher than a year earlier, with next-quarter guidance of $50 billion
On the day the lawsuit was filed, shares of both SK Hynix and Samsung closed higher, reportedly on earnings optimism rather than legal risk — though exact percentage moves are reported inconsistently across outlets, so specific figures are omitted here.
Investment bank Jefferies expects memory prices to climb another 40–50% in Q3 and 30–40% in Q4, with elevated pricing persisting through 2027 and meaningful stabilization not likely until 2028. In other words, regardless of how the lawsuit plays out, elevated memory prices look set to stick around for a while.
The Bottom Line
This case is still at an early stage — a complaint has been filed, but no court has ruled on the merits, and the allegations remain just that: allegations.
The same set of facts — the HBM pivot, the supply cuts, the price surge — is being read in two completely different ways. Plaintiffs call it collusion; the companies call it a rational response to surging AI demand. Historical precedent has generally favored the companies’ side of that argument, but with new evidence introduced this time around, it’s too early to predict how this one will land.
Whether you’re a consumer feeling the pinch of higher device prices or an investor watching these stocks, this is a case worth following closely in the months ahead.
