KEY POINTS
- AI demand has drained the world’s memory supply, with Gartner tipping DRAM prices up about 125% and NAND up 234% in 2026.
- The clear winners are the three big makers, Micron, SK Hynix and Samsung, with sold-out capacity and rare pricing power.
- On the ASX, next-generation memory plays like Weebit Nano and 4DS Memory ride the theme, but they are speculative and do not sell DRAM directly.
- The squeeze looks set to last into 2027, though much of the good news may already be in the big winners’ share prices.
A new kind of inflation is hitting the tech world, and the market has a name for it: “memflation.” Research firm Gartner expects DRAM chip prices to jump around 125% in 2026, with NAND storage chips up a huge 234% in a single year. The cause is artificial intelligence: AI servers need far more memory than normal computers, and that memory is sold out well into next year. Shortages create winners, so who benefits?
What ‘Memflation’ Actually Means
The key fact comes from Micron itself. The special memory AI chips need, called HBM, use about three times the factory space of normal memory to store the same data. So switching a factory to HBM means around three times less ordinary memory. HBM now uses about 23% of all memory production, up from 19% a year ago, starving the supply of everyday chips. That may sound technical, but it means memory has become scarce and valuable for the first time in years. In our view, this is a lasting supply shift, not a normal cycle.

The Direct Winners Are the Memory Giants
The most obvious winners are the only three firms that make this memory at scale: Micron (NASDAQ: MU), SK Hynix and Samsung. Together, Samsung and SK Hynix control more than 70% of the market, and all three have sold out much of their 2026 output under fixed-price, multi-year deals.
That is rare in a boom-and-bust industry, giving the makers steady income and fast-growing margins. Micron reports its fiscal third-quarter results this Wednesday, 24 June, with analysts tipping around US$34.8 billion in revenue and the company guiding to gross margins near 81%, the next test of whether the boom holds. The catch for local investors: these names trade in the US and Korea, not the ASX.
The ASX Angle: Next-Generation Memory Plays
For ASX exposure, the closest fit is a small group of local firms in next-gen memory and chips. Weebit Nano (ASX: WBT), now worth around A$1.8 billion, makes ReRAM, a new memory faster and more power-efficient than today’s Flash, and has signed deals with chip giants onsemi and Texas Instruments. 4DS Memory (ASX: 4DS), a tiny A$23 million company, chases a similar prize at a much earlier, riskier stage.
Other chip-linked names: BrainChip (ASX:BRN) in low-power AI chips, Archer Materials (ASX:AXE) in quantum chips, and Adisyn (ASX: AI1), tackling chip heat with graphene. The honest catch: none of these firms sells DRAM, so they ride the theme, not the price jump. All are early-stage and speculative.
The Investor’s Takeaway
The shortage looks set to last. New memory factories take years to build, the three-to-one HBM problem is not going away, and analysts expect tight supply into 2027 and possibly 2028. The risk is that the easy money in the big makers may already be priced in, with Micron shares up sharply this year.
The ASX names depend on hitting their own technology milestones, not the memory price. And the trade can swing fast: if factories ramp up quicker than expected, or AI spending slows, the squeeze could unwind. For investors, memflation is a powerful theme, but we believe the smarter play is companies with real contracts and clear catalysts, not chasing the headline.
