This seems to almost be mentioned off-hand, but isn't this a really bad and un-free market, and a much bigger issue? Korean companies are afraid of doing business with Chinese companies because of the US, because of retaliation? This was not the "free and global market" I thought we were supposed to have at this point.
If production lines of DRAM are hindered by the politics of a unrelated 3rd party, then this seems to be a stronger cause of the current shortage than "a very large customer buying a lot in a short period of time".
> This was not the "free and global market" I thought we were supposed to have at this point.
Perhaps you haven't noticed but the pendulum has been swinging the other way for a while already and has a lot of momentum behind it. It's mentioned off-hand because the ongoing return to a multi-polar global order is covered elsewhere already, across dozens of articles every day.
Admittedly, Europe was being slow to reconfigure until finally forced to do so this head but they've jumped on board now too.
And in typical historical fashion, everybody with less little influence/independence to project their own sphere are now cautiously but attentively jockeying to accumulate the best deals they can gather among those they do.
The world is far from united, even if many do happen to share opinion about the administration.
Err… is there any question that the US is trying to slow down China’s high-tech computer development? I thought that was our open goal.
Countries decided the extent to which they’d like to engage in free trade together. It is a knob that we’d hope our leaders would turn strategically. (Regardless of whether or not we think our leaders actually are doing a good job of it…).
On paper it can sound rational. In reality you look at stuff like cars, for only so long people will tolerate buying a car for $60k when other countries, whom you are also competing with, get buy similar cars for $10-20k from China. Those same vehicles are used to boost productivity in your own domestic industries.
There is always a ton of risk involved with protectionism. Primarily whether your taxpayer-subsidized domestic jobs and hypothetical national security risk significantly outweighs all the very real economic costs.
> buying a car for $60k when other countries, whom you are also competing with, get buy similar cars for $10-20k from China
I'd love to hear your examples of this happening. For $22K you can get a BYD Dolphin Surf in Europe. And that's a pretty small car. What are you paying $60K for in the US that's the same size?
Maybe let's try a different match up. The BYD Atto 3 seems to start around 40K in Europe. It's smaller than a Model Y, and people say it is slightly lower in market position, but close enough. The Model Y starts at around 40K as well.
Are the comparisons between expensive US cars (remember the average is just above 50K, and plenty of perfectly good cars like a Honda Civic can be had for half that) and Chinese cars in China?
What better way to hurt the designated enemy and make others bare the cost?
Trump's America First in practice relies on a near-sided and overly simplistic understanding of the world (Win-lose, whatever is benefitting others must be a hinderance to the USA). Hence fighting the tariff wars against allies (Canada, Eu). Hence destroying Nato' credibility that was carefully built for 70 years. Hence ceasing to be Ukraine's ally (but continuing to be a trade partner, that sells weapons as long as Europe is paying). Hence helping Putin. Hence instigating problems with Taiwan if that means that TSMC will move some manufacturing to the USA.
It's a really miopic view, but at least on their part the behavior is intentional (consequences, on the other hand, are surprise for them).
We left behind any pretense of a free global market once we entered a post-tariff world. You can't have large universal tariffs or even the threat of them and expect the market to act freely, the two are fundamentally incompatible.
I don't think you can have a "free and global market" when countries participate in large-scale state industrial policy. Given those constraints, you have to either enforce a zero-subsidy environment (the US has no power to do this) or you have to accept that trade control is one arm of your foreign policy goals and surrendering it entirely is unlikely to help your aims.
For the most part, free and open trade is beneficial to the Western world order. But I think it's quite straightforward to imagine conditions under which it is not, many of which are currently in effect.
US control of EUV technology is probably the most obvious present one, but limitations on nuclear proliferation are an obvious case where there is no free market. Even selling civilian nuclear technology is controlled.
You may think of it analogously to Free Speech. The dream is complete and total expression. The reality is that if you allow convincing enough liars, your society starts to falter. Consequently, certain kinds of expression are not permitted - notably defamation. Think of it as more a North Star navigation ideal constrained by the trade winds (I suppose the Westerlies would be more relevant, but I couldn't resist the pun).
If you want a couple of reads, I enjoyed A Splendid Exchange about the history of trade, which I followed by the resurgent-though-once-dismissed Zeihan's Disunited Nations (which is more a hypothesis book than a history book).
> I don't think you can have a "free and global market" when countries participate in large-scale state industrial policy.
All industrialized countries participate in large-scale state industrial policy. It's a pre-condition of industrialization. A nation cannot industrialize without large scale state policy. And once industrialized, all nations maintain large-scale state industrial policy. Are you saying there never has or can be a "free and global" market? Or just when china does it?
> You may think of it analogously to Free Speech.
It's nothing like free speech as free speech is a constitutional right granted within a nation.
> The reality is that if you allow convincing enough liars, your society starts to falter.
That's rich coming from someone peddling zeihan. I've always wondered what kind of morons actually believe his nonsense. Now I know.
The US industrialized without much in the way of large scale state industrial policy. The federal government was quite weak in the 19th century and, excepting tariffs on British goods, I can't think of any explicit policies it established that were intended to foster industrial capacity. And I think it's debatable how much tariffs actually helped the US develop its manufacturing capacity
> The US industrialized without much in the way of large scale state industrial policy.
What? From funding the Lewis&Clark missions, to forcing japan open, to clearing out the natives for railroad companies, to helping found colleges ( check out many engineering/tech focused colleges like MIT was founded in the 1800s ). You can even argue that american independence and the civil wars were about expanding state industrial policy.
> The federal government was quite weak in the 19th century
So "weak" that we went from 13 small states on the east coast and expanded 3000 miles all the way to the pacific? What the hell are you talking about?
> I can't think of any explicit policies it established that were intended to foster industrial capacity.
The US became the dominant industrial power in the 1800s and you can't think of any policies that helped? You think all the territories in the ohio valley, texas, oklahoma, california, etc chock full of oil were just given to americans by overly generous natives, brits or mexicans? Are you a moron?
If the US didn't have state industrial policy, the US would have never become and industrial power. We'd have just gone down the jeffersonian agrarian paradise road.
It's becoming increasingly clear that OpenAI is going to get lapped by Google on technical merits. So this is the "code red" solution? Supply shenanigans?
They are getting beat in the developer market by Anthropic. And getting beat on fundamental tech by Google. This is a company whose ostensible mission is to "benefit all of humanity" ...
As in producers not over-producing RAM should be illegal? A presumably short-term price spike in RAM of all things is a non-issue. It is a luxury good that only a very small number of people care about and there is no reason to think this blip is going to last. Apple did stuff like this all the time at their high point in the late 2000s and early 2010s, and it would happen often in other markets. The world is not static and sometimes the situation changes and lots of supply is soaked up.
Who in the developed world doesn't have a few luxuries? Pretty much all of history people have had to make do with RAM being a lot less accessible than it is now. It isn't essential and people can still buy RAM in the rare situations where they actually need it.
There is nothing here worth invoking the legal system over. OpenAI can buy huge amounts of RAM if they want. Good luck to them, hope it works out, looks like an expensive and risky manoeuvre. And we're probably going to have a RAM glut in a few years looking at these prices.
DRAM is one of the categories of advanced semiconductors that the US considers important enough to national security that exporting it to China is forbidden. It's a fundamental industrial product.
Yeah. Companies like OpenAI need a lot of RAM. That is why they just bought up what is apparently a material chunk of the market.
There is a certain level of crazy that crowds can find when people identify something as a fundamental industrial product critical to national security and simultaneously someone is calling for companies buying a lot of it [0] to be made illegal. If something is critically important to industry then companies should be encouraged to dump as much money as they like in the sector. Otherwise industry will suffer.
[0] And OpenAI is probably going to turn out to be closely associated with US national security too.
Market manipulation is a crime under the Securities Exchange Act of 1934. You can't buy things to influence the price or the market, only to use or resell.
It doesn't really matter, because the first question is: can the government suspend the contract (injunction?) while this is sorted out.
There's also the question of if OpenAI operated In good Faith (from a search: "Another sign of bad faith is withholding crucial information..."), and- of course- the South Korean government can step in as well. In fact- as a worldwide issue- any sufficiently large State(or group of States) can take issue with it.
OpenAI will have issues if they find themselves unable to buy power equipment (Schnider, Eaton). Or, perhaps anybody associated with OpenAI management or funding is arrested the second they step foot in Europe. This is already a nightmare of an International Incident.
It's interesting that this isn't actually illegal to do except in the specific context of an exchange market. I did a very cursory search of the US Code and the Securities Exchange Act of 1934 and yeah, unless there's some additional legal precedent or other applicable law I didn't find, then this might just be a gap in the law.
It even seems to skirt around notions of illegal vertical integration. For example in this address from 1998, a former FTC commissioner describes several types of illegal "vertical alliances", all of which rely on both the upstream supplier and the downstream consumer being aligned in anticompetitive intent, which (if the article is to be believed) they couldn't have been here because there are two suppliers who were unaware of each other's deals.
Is it really not illegal to just buy up a huge chunk of a critical input for an industry and stockpile it for the purpose of locking out competitors? Seems hard to imagine that some robber baron of the 19th century didn't already do this.
Let's not forget that if it's not illegal now, it could be illegal in a matter of days. Add 12 if a president decides to sit on their thumbs, it's happened before.
That'd probably make more sense if there wasn't also 50 other tech companies buying up RAM for the same reason (a sudden huge spike in demand due to AI taking off).
They mean to resell them in a different form: as part of their PaaS or SaaS. Per the article, OpenAI is just hoarding the wafers, not purchasing the final product.
It's about volume, not a naive count of consumers. Article claims that OpenAI holds contracts for 40% of world DRAM production. That's just really obviously manipulation if they can't actually power those chips, come on.
So the prosecution will gamble that OpenAI won't in fact use the RAM in a relevant timeframe and they only bought them to exclude the other swath of AI companies from competing?
From the article
> OpenAI isn’t even bothering to buy finished memory modules! No, their deals are unprecedentedly only for raw wafers — uncut, unfinished, and not even allocated to a specific DRAM standard yet. It’s not even clear if they have decided yet on how or when they will finish them into RAM sticks or HBM! Right now it seems like these wafers will just be stockpiled in warehouses – like a kid who hides the toybox because they’re afraid nobody wants to play with them, and thus selfishly feels nobody but them should get the toys!
I guess we'll have to see if they in fact just keep "unfinished" RAM in warehouses like the article says and not roll them out into datacenters for a legitimate use as they are finished.
Should be, as in, new legislation should criminalize it? What's the generalized principle? Or should be, as in existing law should cover it? And if so, what law / how?
It wouldn't shock me if this is actually just market manipulation. OpenAI in the past year seems to be operating more and more like a pump and dump machine. Their recent AMD deal seems to have been AMD giving them a bunch of stock for free in exchange for them announcing that they would use AMD GPUs for training, and OpenAI doesn't have any fab equipment so the only thing they can do with 40% of the global dram supply is sell it to someone else.
There's nothing dirty about this deal. When making a large deal with one vendor he didn't disclose to them that he was making a deal with another vendor. That's pretty normal when you're trying to buy a lot of stuff. Otherwise, they can collude to shake you down.
I'm not thrilled about this genre of "guy I don't like does totally normal thing so it's bad". It's too engagement baity.
EDIT: Though even that may be wrong. TechCrunch reports that it was a joint meeting between the South Korean President, the heads of the two companies, and Sam Altman. I won't claim that TC is the bible but there's lots of stuff being reported that makes no sense, and this is a good deal for both these companies so it's more believable than news from someone that OpenAI is going to buy a bunch of wafers and stick it in a warehouse.
It's bad for consumers period. A deal that hampers 40% of global supply shouldn't be a thing, it's predatory. I know DRAM is not a necessity, but considering that PCs are going to be affected means this affects real things like schools and hospitals. There's being smart while making a deal and there's knee-capping the market with your leveraged to the tits business
> OpenAI isn’t even bothering to buy finished memory modules! No, their deals are unprecedentedly only for raw wafers — uncut, unfinished, and not even allocated to a specific DRAM standard yet.

It's not really that different from Apple reserving wafer starts on TSMC's next node and so on. It's just that this kind of capacity requirement has rarely shown up in DRAM before. Vendors prefer this kind of capacity reservation over a more variable finished product requirement. It allows them to know that they can build at the bottleneck rather than having to start up more capacity and then having that lie idle while everything downstream in DRAM packaging and DIMM production can't actually consume anything.
I don't buy it. It's easier to make this argument for companies that are building their own hardware, since they know it can be immediately used. OpenAI's move is tantamount to hoarding for the sake of strangling competition. There was plenty of supply to allow for their plans without this move (especially since they will probably go bankrupt at this rate).
Granting this premise is true (I have no idea), that makes it even worse. They would deliberately be hoarding 40% of the global supply not to lock in for future growth but simply to make sure no one else gets to have it. It’s figuratively setting chips on fire.
It seems not normal (in the sense that it is obviously quite weird to but like half of the world’s RAM supply). But I wonder if they are also just not ready to announce what they are doing with it?
I mean with that many wafers, I guess it is possible that they’d be doing something pretty custom with the things…
Guys, these are silicon wafers not bars of steel. You can't just stockpile 40% of annual capacity in a warehouse long-term. I would be incredibly surprised to find that any such large scale storage facility exists. Any storage of undiced wafers is temporary while the manufacturing pipeline proceeds. You've seen the pictures of clean rooms and stuff. There's no way you spend all that effort to make the wafer and then just stick it in a warehouse. Who even is going to make such a large cleanroom facility? And for what exactly? It doesn't even pass the basic sniff test.
Much more likely this is just a detail of the contract so that OpenAI can guarantee allocation. I would be surprised if the actual wafers entered OpenAI hands before being fully packaged.
> It would require half of one distribution center of a major retailer.
That also meets the specifications of a clean room, and is actively maintained as one?
If OpenAI bought 40% of the annual capacity of finished memory, with the goal of using it in their server farms ASAP, that's one thing.
But unfinished wafers that still need to be protected to finish the manufacturing process, that OpenAI itself does not have any capability to do?
That to me looks like a preemptive strike against competitors, which also affects any other industry that requires RAM, in an attempt to develop a monopolistic position.
I can't see how this isn't a massive national security issue for any country that needs devices requiring RAM for new systems and maintenance of existing ones (pretty much all of them...) to manage critical infrastructure, national defence, public and social services, and so on.
Correct. It's rather routine for wafers manufactured for "last call" orders on ASICs exiting production to be stored as wafers due to not knowing how they need to be Packaged.
I like how one of the reference links betrays how the article itself was researched, possibly written; HN hides the end of the url, which is "utm_source=chatgpt.com":
The real disappointment is none of the sources are linked in the text. Instead, it's just random underlined words, the classic chatgpt over formatting with lots of extra underlining and bolding.
I appreciate that a 10-15 minute long article summarizes a 25 minute video, but it's hard to hide the real author.
> To be clear - the shock wasn’t that OpenAI made a big deal, no, it was that they made two massive deals this big, at the same time, with Samsung and SK Hynix simultaneously
That's not "dirty." That's hiding your intentions from suppliers so they don't crank prices before you walk through their front door.
If you want to buy a cake, never let the baker know it's for a wedding.
What they mean is that they bought 40% of all RAM production, they managed to do that by simultaneously making two big deals at the same time. It's buying up 40% of all RAM production with the intention to have most of it idle in warehouses that is "dirty". And in order to be able to do that, they needed to be secretive and time two big deals at the same time.
The incentive suggested in the article is to block other competitors from scaling training, which is immensely RAM hungry. Amongst other things. Even Nvidia could feel the pressure, since their GPUs need RAM. It could be a good bargaining chip for them, who knows.
I'm not saying it's true, but it is suspicious at the very least. The RAM is unusable as it stands, it's just raw wafer, they'd need a semiconductor fab + PCB assembly to turn them into usable RAM modules. Why does OpenAI want to become a RAM manufacturer, but of only the process post-wafer.
That's not the dirty part. This is the dirty part:
> OpenAI isn’t even bothering to buy finished memory modules! No, their deals are unprecedentedly only for raw wafers — uncut, unfinished, and not even allocated to a specific DRAM standard yet. It’s not even clear if they have decided yet on how or when they will finish them into RAM sticks or HBM! Right now it seems like these wafers will just be stockpiled in warehouses
> OpenAI isn’t even bothering to buy finished memory modules
And? Why should they be obligated to pay for all the middleman steps from fab down to module? That includes: wafer-level test, module-level test (DC, AC, parametric), packaging, post-packaging test, and module fabrication. There's nothing illegal or sketchy about saying, "give me the wafers, I'll take care of everything else myself."
> not even allocated to a specific DRAM standard yet
DRAM manufacturers design and fabricate chips to sell into a standardized, commodity market. There's no secret evolutionary step which occurs after the wafers are etched which turns chips into something which adheres to DDR4,5,6,7,8,9
> It’s not even clear if they have decided yet on how or when they will finish them into RAM sticks or HBM
The implication here is that the primary goal is to corner the market, not to use the supply. If you aren't going to use them anyways then of course it is silly to pay for them to be finished.
Do you think that's fine, or do you think that implication is wrong and OpenAI does actually plan to deploy 40% of the world's DRAM supply?
> The implication here is that the primary goal is to corner the market
You have no evidence of that. Even at face value, the idea of "cornering the market" on a depreciating asset with no long-term value isn't a war strategy, it's flushing money down the toilet. Moreover, there's a credible argument OpenAI wanted to secure capacity in an essential part of their upstream supply chain to ensure stable prices for themselves. That's not "cornering the market," either, it's securing stability for their own growth.
Apple used to buy-up almost all leading-edge semiconductor process capacity from TSMC. It wasn't to resell capacity to everyone else, it was to secure capacity for themselves (particularly for new product launches). Nvidia has been doing the same since the CUDA bubble took off (they have, in effect, two entire fabs worth of leading-edge production just for their GPUs/accelerators). Have they been "cornering" the deep sub-micron foundry market?
Yes, they've made insane scaling bets before and they have paid off.
If what we've heard about no acceptable pre-training runs from them in the last two years trying to increase the memory for training by two orders of magnitude is just a rehash of what got them from gpt2 to gpt3.
I remember it didn’t work out well for Randolph and Mortimer. Sam may pull it out, though, if he just sells the DRAM now while the market is still hot.
I'm curious how OpenAI has the funds to pay for 40% of the worlds ram production? Sure they are big and have a few billions but I kind of assumed that 40% for a year or whatever they are buying is easily double digit billions? That has to hurt even them, especially because they cant buy anything else?
Also what are these contracts? Surely Samsung could decide to cancel the contract by paying a large fee but is that fee truly so large that getting their ram back when prices are now 4x of what they used to be is not worth it?
I assume this includes more than just the raw price of modules but Openai only has 60 billion in funding altogether and was aiming for 20 billion ARR this year. This sounds like they are spending maybe half their money on RAM they never use? That just doesn't add up.

> your business model might end up being sort of a … startup incubator or private equity firm; you’d spend your time starting or acquiring companies on which the robot could work its magic. Your business model would be “general business, but with AI.” .. OpenAI has a $500 billion valuation largely as a bet that a lot of the value of AI will accrue to its builders, but it could hedge that bet by owning the users too. Either it will sell AI at high margins to lots of businesses, or it will sell AI at lower margins to lucrative businesses that it owns.
Secondary RAM Manufacturing Had Stalled. Budget brands normally buy older DRAM fabrication equipment from mega-producers like Samsung when Samsung upgrades their DRAM lines to the latest and greatest equipment. This allows the DRAM market to expand more than it would otherwise because it makes any upgrading of the fanciest production lines to still be additive change to the market. However, Korean memory firms have been terrified that reselling old equipment to China-adjacent OEMs might trigger U.S. retaliation…and so those machines have been sitting idle in warehouses since early spring.
My takeaway, this sounds like an comparably easy fix for the consumer market, if prices are somewhat guarenteed to stay mid term significantly above this years spring floor for someone to sweep up the margins and negotiate a somewhat reliable way to get the last gen production lines up and running again.
Will take at least half a year to pick up, but this is not a longterm RAM doomsday scenario in any sense.
I'm more worried about the low to mid-end embedded systems, that a have a dollar budget for memory components, that could get unbearably slow for the current/next gen if manufactures just use the bare minimum of RAM the bloated TV or tablet OS can run on, if the 1GB raspberry move is any indication of that. And consumers stuck with no way to upgrade them to a reasonably usable state.
One of the big problems here is that all of the hardware companies have been burned by hype before (e.g. crypto). No one actually believes that these AI companies will still be around in 5 years so spending billions to build factories for them doesn't make sense.
I don't know what companies will be around 5 years from now, but I would bet there will be more demand for RAM and the price per GB will be at least what it was before this price shock.
RAM is a very cyclical market, historically. You can look at $MU historical charts and kind of see that it trades like a cyclical (compare it to $RIO, for example).
Cyclical companies are easily burned by investing in infrastructure right at the peak. It happens all the time with little mining companies, and I think DRAM manufacturers are sort of the mining companies of tech.
With the amount of hatred for anything OpenAI it’s not surprising the author chose a clickbaity title. HNs quality of posts are going down and instead of objective analysis I often see very polarized and flamy articles, titles etc.
Yes, I have an older gaming PC from ~2018 that I keep putting off upgrading (first GPU prices skyrocketed, now this...) and was hoping to replace it with a Steam Machine next year. Will be endlessly bummed if that doesn't happen.
Will also be interesting if Sony/Microsoft was planning on releasing a next-gen system anytime soon, and I wonder if this will affect Apple's hardware at all.
And all these data centers they want to build around the country. When consumers can’t get devices they want maybe they’ll fight even harder against these data centers being built in their back yard. He’s not making any fans with this move that’s for sure
They definitely can, as anybody could, for a short enough period of time. The only ones betting they'll be able to sustain it for a long period are the ones paying the currently very inflated price for ram.
but it's not a short term deal. funny enough, there's a cohort of bonds that never even made one payment. They are called first payment default bonds. There is a cheekier nickname for them, but it escapes me at the moment.
almost feel like OpenAI's recent "fall" is a decoy setup by them intentionally.. something's cooking.. maybe they wanted to buy back their own shares at a lower price?
OP is also marginally underestimating the impact this move would have on Google's competitiveness - they are making huge gains prototyping at light speed; this will halt their AI hardware acceleration plans pushing them back into slower software development on ever aging hardware.
It also shows why Nvidia is not afraid of competitors coming out with new desgings that obsolete their hardware: what good are superior designs with no fabs to produce them?
every one of these things that make the deal "good" for OpenAI is a direct result of negative externalities for everyone else: competitors, consumers, and people who wouldn't care otherwise.
The article even says that they don't have an obvious plan for how to use the wafers they bought, and very clearly suggests that this is purely an anticompetitive tactic to force everyone else to eat a price increase that OpenAI doesn't need to face. It's clever though because if any regulatory agency starts asking questions (not that they would do that in the current USA political climate) then OpenAI can just say it's a strategic reserve, we have plans to do something with it, etc. etc. What are you going to do? Take them to court and force them to auction off some % of the stock? Set an industry-wide limit on wafer inventory? Fine them? You'd need to find some evidence that it was done maliciously, and good luck with that.
There are some negative elements of captialism that we might simply have no reasonable regulatory apparatus to deal with. Preventing indivduals and companies from having so much market power in the first place seems to be the only thing that can work consistently.
As an AI researcher, I thought it was relatively well established (at least among my colleagues) that being pro-AI actually meant you were anti-Sam as well. He's the worst actor in the industry and has done an incredible amount of damage to its brand.
This seems to almost be mentioned off-hand, but isn't this a really bad and un-free market, and a much bigger issue? Korean companies are afraid of doing business with Chinese companies because of the US, because of retaliation? This was not the "free and global market" I thought we were supposed to have at this point.
If production lines of DRAM are hindered by the politics of a unrelated 3rd party, then this seems to be a stronger cause of the current shortage than "a very large customer buying a lot in a short period of time".
