China Just Broke the DDR5 RAM Cartel — $400 RAM Drops to $70

CXMT's 719% revenue surge shows China breaking the DRAM memory cartel that export controls overlooked. Commodity DDR5 prices spike as Samsung, SK Hynix and Micron pivot to AI.

Key Takeaways

US export controls targeted the wrong chokepoint: China's gains came in commodity memory, not frontier logic.
The Big Three's pivot to AI-focused HBM created a shelf shortage that opened a market gap for CXMT.
CXMT's growth is real but starts from a small base, and its shortage-driven margins may not persist.
On cutting-edge AI memory, CXMT remains behind; on commodity DRAM, it is becoming a serious competitor.

What the video covers

Export controls focused on advanced AI processors and EUV lithography, leaving commodity DRAM memory largely unguarded.
Samsung, SK Hynix and Micron control over 90% of global DRAM, creating a profitable oligopoly.
Big three shifted fab capacity to high bandwidth memory (HBM) for AI customers, since HBM consumes about three times the wafer capacity per gigabyte.
This pivot created a commodity DRAM shortage: Samsung's 32GB DDR5 kit reportedly rose from about $149 to $239 in one month, and some components jumped up to 1,000%.
Changxin Memory Technologies (CXMT), founded in 2016 in Hefei, reported Q1 2026 revenue of roughly 50.8 billion won, up 719% year over year.
CXMT's commodity DDR5 does not require EUV, only deep ultraviolet multi-patterning and volume, which it can achieve.
CXMT runs a 16nm-class process versus Samsung's 12nm, trailing leaders by roughly 2 to 3 years.
CXMT plans to raise monthly wafer capacity to 420,000 by 2027 and reportedly targets doubling by 2030.
CXMT has sampled 12-layer HBM3 to Huawei, but estimated HBM yields are only 10 to 25%, so it is not yet a credible elite AI memory challenger.
CXMT showcased a full DDR5 lineup (UDIMM, SODIMM, RDIMM) and LPDDR5X, and its G4 DDR5 has reportedly appeared in retail kits.

What is CXMT and why does its revenue growth matter?

CXMT (Changxin Memory Technologies) is a Hefei-based DRAM maker founded in 2016. It reported roughly 50.8 billion won in Q1 2026 revenue, up 719% year over year, showing it is capturing share in commodity memory as the big three focus on AI.

Why did the big three memory makers cause a commodity DRAM shortage?

They shifted fab capacity to high bandwidth memory for AI, which uses about three times the wafer capacity per gigabyte as regular DRAM. This left consumer and commodity DDR5 supply tight, pushing prices up sharply.

Is CXMT a credible competitor to Samsung and SK Hynix in AI memory?

Not yet. The transcript says CXMT trails leaders by 2 to 3 years on process technology, and its estimated HBM yields of 10 to 25% make it a credible challenger only in commodity memory for now.

Speaker A

The memory chip cartel is breaking. And the US export controls were supposed to prevent exactly this. Changxin Memory Technologies just reported a 719% revenue surge. While Washington was obsessed with stopping China from making the world's most advanced AI processors, China quietly attacked something much more basic. Memory.

Speaker A

China quietly attacked something much more basic. Memory. And now the company the controls were supposed to constrain is coming for a market dominated by Samsung, SK Hynix, and Micron.

Speaker A

And now the company the controls were supposed to constrain is coming for a market dominated by Samsung, SK Hynix, and Micron.

Speaker A

Nobody was guarding the memory door. And while the world argued about ASML and TSMC and advanced nodes, a company founded in 2016 walked straight through that door [music] and took a piece of the most profitable cartel in electronics.

Speaker A

Here is the mistake that gave China an opening. Everybody was watching the wrong chip. Every sanction, every blocked EUV lithography machine, every headline about who could print 7 nanometer logic, all of it was aimed at processors.

Speaker A

First, you need to understand what actually happened to your wallet. Because this was not random.

Speaker A

Nobody was guarding the memory door. And while the world argued about ASML and TSMC and advanced nodes, a company founded in 2016 walked straight through that door and took a piece of the most profitable cartel in electronics.

Speaker A

Between them, they control north of 90% of all the DRAM on the planet. Your PC, your phone, your laptop, the server your bank runs on, all three of them, all the time.

Speaker A

Stay with me. Because the number that proves it is about 30 seconds away. And when you hear it, you are going to think I misread it.

Speaker A

Here is the trap nobody outside the industry saw. Micron has said that a single gigabyte of HBM burns through roughly three times the wafer capacity of regular DRAM.

Speaker A

First, you need to understand what actually happened to your wallet. Because this was not random.

Speaker A

[music] They took the fabs that were making your memory and pointed them at the AI customers who pay [music] more.

Speaker A

For decades, the memory world has been run by three companies: Samsung, SK Hynix, and Micron.

Speaker A

Samsung pushed a 32 gigabyte DDR5 kit from around $149 to 239 in a single month.

Speaker A

Between them, they control north of 90% of all the DRAM on the planet. Your PC, your phone, your laptop, the server your bank runs on, all three of them, all the time.

Speaker A

And internally, [music] SK Hynix reportedly thinks this squeeze runs until 2028. That is not a shortage.

Speaker A

Then artificial intelligence blew up, and AI does not want normal memory. It wants high bandwidth memory, HBM, the stacked stuff that sits pressed up against the big accelerator chips in data centers.

Speaker A

Call it $7 billion. That was up 719% from a year earlier. 719% from a company that did not exist 10 years ago in an industry where a single fab costs more than most countries spend on defense.

Speaker A

Here is the trap nobody outside the industry saw. Micron has said that a single gigabyte of HBM burns through roughly three times the wafer capacity of regular DRAM.

Speaker A

It won because the export controls were pointed somewhere else. Think about what the restrictions actually blocked.

Speaker A

Three times the factory floor for the same gigabyte. So, the big three did the coldly rational thing. They took the fabs that were making your memory and pointed them at the AI customers who pay more.

Speaker A

That was the choke point. And it worked. Chinese logic manufacturing is genuinely constrained by it. But DRAM does not live at the bleeding edge. Commodity DDR5 does not need EUV. It needs deep ultraviolet multi-patterning discipline, and above all, it needs volume. CXMT is

Speaker A

SK Hynix said its memory was essentially sold out for all of 2026. Micron walked away from the consumer channel entirely.

Speaker A

And it did not matter. Because the product the world was screaming for was not the most advanced memory. It was any memory at all.

Speaker A

Samsung pushed a 32 gigabyte DDR5 kit from around $149 to $239 in a single month.

Speaker A

The shortage proved the value was in the shelf. So, what did they actually ship?

Speaker A

Distributors started calling it RAMageddon. And some individual components saw jumps of 1,000%. Apple pulled the high memory Mac mini and Mac Studio configurations off the shelf.

Speaker A

Alongside it, LPDDR5X, the low-power memory for phones and thin laptops, reaching up to 10,667 mega transfers per second.

Speaker A

And internally, SK Hynix reportedly thinks this squeeze runs until 2028. That is not a shortage. That is a vacuum. And vacuums get filled.

Speaker A

is the detail that separates a trade show render from an actual shipping product. Look at what that list covers.

Speaker A

Now, here is the number. Changxin Memory Technologies, CXMT, based in Hefei, posted first quarter revenue in 2026 of roughly 50.8 billion won. Call it $7 billion. That was up 719% from a year earlier. 719% from a company that did not exist 10 years ago in an industry where a single fab costs more than most countries spend on defense.

Speaker A

That is a company reading a market and driving a truck through the gap. And then, there is the margin math, [music] which is the part that should genuinely worry Seoul and Boise.

Speaker A

And this is where the geopolitics gets genuinely interesting, because CXMT did not win by beating the export controls. It won because the export controls were pointed somewhere else. Think about what the restrictions actually blocked.

Speaker A

80%. Which means that even if CXMT costs twice as much to manufacture per chip, it could still run a 60% margin and undercut everybody in the market.

Speaker A

Extreme ultraviolet lithography. The machines you need to print leading edge logic at three and two nanometer.

Speaker A

That is what happens when a cartel gets comfortable. Then in July of 2026, they cashed the whole thing in.

Speaker A

That was the choke point. And it worked. Chinese logic manufacturing is genuinely constrained by it. But DRAM does not live at the bleeding edge. Commodity DDR5 does not need EUV. It needs deep ultraviolet multi-patterning discipline, and above all, it needs volume. CXMT is running a 16-nanometer class process, while Samsung pushes into 12 nanometer. So, on raw technology, they still trail the leaders by roughly 2 to 3 years.

Speaker A

more fabs. The stated plan is to push monthly capacity to 420,000 wafers by 2027, from around 280,000 to 300,000 today, with talk of doubling by 2030 and tripling [music] by 2035.

Speaker A

And it did not matter. Because the product the world was screaming for was not the most advanced memory. It was any memory at all.

Speaker A

Now, some honesty, because this channel does not sell fairy tales. CXMT has largely addressed the commodity memory problem. It has not solved the problem that started the crisis.

Speaker A

That is the strategic blind spot. The control regime assumed the value was in the frontier. The shortage proved the value was in the shelf. So, what did they actually ship?

Speaker A

They are working on 12-layer HBM 3, [music] and have reportedly sampled it to Huawei for the Ascend accelerators. But industry estimates put their HBM yields somewhere in the 10 to 25% range.

Speaker A

At the China International Semiconductor Expo in late 2025, CXMT pulled the sheet off a full DDR5 lineup running up to 8,000 mega transfers per second in 16 gigabit and 24 gigabit densities.

Speaker A

climbs. The 719% growth figure is also a comparison against a very small base. And margins of that shape in a shortage are [music] shortage margins.

Speaker A

Alongside it, LPDDR5X, the low-power memory for phones and thin laptops, reaching up to 10,667 mega transfers per second.

Speaker A

Earth. On elite AI memory, they are a credible challenger and nothing more than that yet.

Speaker A

And they did not show one hero product for the cameras. They showed the entire catalog. UDIMM for desktops, SODIMM for laptops, RDIMM for servers. Their G4 generation DDR5 had already been found in the wild inside retail kits from a brand called Gloway, which is the detail that separates a trade show render from an actual shipping product. Look at what that list covers.

Speaker A

Tactically, [music] a 10-year-old company just broke into a 30-year oligopoly by refusing to compete where the incumbents were strong.

Speaker A

It is almost item for item the exact set of products the big three abandoned to chase AI margins. That is not a coincidence, and it is not luck.

Speaker A

And existentially, the whole architecture of technology restriction just revealed its assumption. It assumed the frontier was the choke point. It assumed that if you control the most advanced node, you control the industry.

Speaker A

That is a company reading a market and driving a truck through the gap. And then, there is the margin math, which is the part that should genuinely worry Seoul and Boise.

Speaker A

The controls held the door they were watching. Nobody noticed the door beside it was never locked.

Speaker A

Memory analyst Jim Handy pointed out that the majors are currently pulling something in the range of 80% gross margins on DRAM.

Speaker A

Because we track the moves that don't make the headlines. The shifts that rewrite global power before the mainstream catches on.
