RAM Price-Fixing Lawsuit: What It Means for UK Buyers
Samsung, SK Hynix and Micron face a US lawsuit alleging RAM price-fixing. Here's what it means for UK RAM prices and whether to buy now or wait.
Samsung, SK Hynix and Micron face a US lawsuit alleging RAM price-fixing. Here's what it means for UK RAM prices and whether to buy now or wait.
Samsung, SK Hynix and Micron are being sued in the United States over claims that this year's memory crisis wasn't just bad luck, it was manufactured. If you've priced up a build recently and watched a 32GB DDR5 kit cost noticeably more than it did back in March, this lawsuit puts a name to the accusation that's been circulating among PC builders for months: the RAM shortage isn't only AI demand outrunning supply, it's alleged coordinated supply discipline by the three companies that between them make almost all the world's DRAM. Below is what the case actually says, why a lot of buyers aren't inclined to give these firms the benefit of the doubt, and what it changes about how you should shop for RAM this year.
The case was filed on 25 June 2026 in the US District Court for the Northern District of California by the antitrust firm Bathaee Dunne LLP, on behalf of 14 individual buyers and three small PC-building businesses, and it is seeking class-action status. The central claim is that Samsung, SK Hynix and Micron, which together control roughly 90% of the global DRAM market, coordinated to hold back DDR3 and DDR4 production and steer manufacturing capacity toward high-bandwidth memory for AI datacentre customers instead, fully aware it would starve the consumer market of standard memory.
The complaint puts the resulting price increase on some DRAM products as high as 700%. That figure comes from the filing itself rather than an independent market report, so it's an allegation the plaintiffs will have to prove, not a verified statistic. It's also a maximum, cited for the worst-affected product lines rather than typical of what a UK buyer sees on a standard DDR5 kit.
There's a legitimate, entirely legal version of this story. AI-focused high-bandwidth memory commands far higher margins than consumer DDR4 or DDR5, so a chip maker reallocating wafer capacity toward it is simply following the money. Companies are allowed to chase their most profitable product line even when it leaves other customers worse off.
What turns that into price-fixing, if the plaintiffs can prove it, is evidence that the three firms acted in concert rather than each independently deciding to favour AI customers. That's a considerably higher bar, and it's what the complaint is trying to establish through internal communications and shipment records it says show the three companies cutting DDR3 and DDR4 output in a synchronised pattern rather than a coincidental one.
This isn't the first time these companies have faced this exact accusation. In 2005, Samsung and SK Hynix (then Hynix Semiconductor) pleaded guilty to DRAM price-fixing in the US and paid fines of $300 million and $185 million respectively. Micron avoided prosecution by cooperating with investigators and handing over evidence against the other two. That history is doing a lot of the work in how sceptically this new case is being received, and it's a large part of why the plaintiffs' lawyers are confident enough to file at all.
Even a plaintiff win wouldn't be quick relief. Class actions on this scale typically take years to resolve, and the usual remedy in a successful price-fixing case is damages paid out to the class rather than a court-ordered cap on future pricing. If that's how this one goes, buyers dealing with high RAM prices in 2026 shouldn't expect the courts to be the mechanism that brings prices back down. Supply eventually catching up with AI demand is doing that job, on whatever timeline the manufacturers choose to let it happen.
Reaction to the case among people actually building PCs has been closer to weary recognition than shock. The general view is that a settlement, if one ever arrives, will take years and won't meaningfully claw back what buyers have already paid, and that a firm with a 2005 guilty plea on file doesn't get much benefit of the doubt the second time round.
There's also a distinction worth drawing that keeps coming up in that discussion. Some component shortages really are unavoidable, driven by genuine external shocks nobody controls. This one looks different, because three companies supply almost the entire market, two of them have already been caught doing exactly this once before, and the timing lines up neatly with the point at which AI demand made switching production away from consumer memory extremely profitable. Whether that adds up to a courtroom win is a separate question from whether it adds up to a reasonable thing for buyers to suspect.
Whatever happens in court, it won't move UK RAM prices this year. US antitrust class actions of this size typically run for years, and even a settlement wouldn't force manufacturers to cut prices going forward, only compensate for past purchases, and usually only for claimants inside the US class. So the near-term picture for anyone buying here is unaffected by the legal process either way.
Only indirectly, and only through what it might eventually change in manufacturer behaviour rather than through any UK legal mechanism. A genuine finding of unlawful supply restriction could, in theory, pressure the three firms to normalise DDR4 and DDR5 output faster than they otherwise would. In practice that's years away even in the most buyer-friendly outcome, and the more immediate driver of UK pricing remains what it's been all along: AI-driven wafer allocation squeezing consumer DRAM supply. If you want the current number rather than a forecast, our RAM price index tracks a matched basket of kits over time, and the live RAM category page shows what UK retailers are charging today, which is more useful than anything printed in a lawsuit filed a month ago.
Buy for the build in front of you, not for a court case. A lawsuit that could still be running in 2028 is not a reason to delay a build you need to finish this year. A few rules hold regardless of how the legal side resolves:
If you're planning a full platform change rather than a memory swap, check our motherboard and CPU pages first, since your RAM generation, DDR4 or DDR5, usually decides which boards are even compatible with your shortlist before price enters the conversation.
Not fundamentally. If you're on an older platform that takes DDR4, this shortage is a reason to buy the kit you need and move on rather than jump platforms purely to chase DDR5, since DDR5 kits have generally seen the sharper percentage increases as AI-adjacent production shifts have concentrated there. If you're building fresh on a current AM5 or LGA1851 platform, DDR5 remains the only sensible choice regardless of price, since DDR4 boards for those sockets barely exist. The shortage changes the price you'll pay either way, but it doesn't change which memory standard your platform actually needs, so don't let the lawsuit or the headlines push you toward a platform decision that isn't yours to make.
RAM is the most visible casualty of AI's appetite for memory capacity, but it isn't the only one. NAND flash faces a similar reallocation story, part of why SSD prices have also moved sharply this year, and GPU makers have been open about prioritising datacentre customers over gaming cards, a trend we've tracked in detail on the GPU pricing page. The pattern repeating across categories is consistent: any component with a viable AI-datacentre use finds itself pulled away from the consumer market, and what's left behind gets more expensive because fab capacity didn't grow fast enough to cover both. A verdict against Samsung, SK Hynix and Micron, even a successful one, wouldn't reverse that underlying demand shift. Plan your build around the market you're actually shopping in, not the one you'd prefer to be shopping in a year from now.
Whichever way the case goes, the practical answer for anyone building a PC in the UK this year hasn't changed: check what kits are actually costing today, buy what your build needs, and don't let a multi-year court case talk you into either panic-buying or an indefinite wait.
