CXMT Starts Mass-Producing Cheaper DRAM as Rivals Bet the Shortage Lasts to 2030

Days after data showed CXMT at 9.5% of global DRAM revenue with the industry's best operating margin, the Chinese maker put a fifth-generation platform into volume production. Micron's 30 September report is the shortage story's first test.

DRAM's new fourth player ships its fifth generation

At the World Manufacturing Convention in Hefei on Sunday, 20 September, CXMT said its fifth-generation DRAM platform, G5, has entered mass production, alongside two 24-gigabit LPDDR5X chips built on it 12. CXMT is China's largest memory maker and now the world's fourth-largest DRAM maker by revenue 13. The named buyers are phone brands: Nubia, Xiaomi−3.74% — Xiaomi, down 3.74 percent today and Transsion 1.

The process shrinks the tightest feature in the memory cell to 11.95 nanometres using quadruple patterning, which the company says brings it close to the 10-nanometre-class platforms Samsung and SK Hynix already run in volume, with at least 50% more dies per wafer and a lower cost per chip 12.

Scarcity to 2030 is the priced case

The bull case rests on two assumptions already in the prices. SK Hynix, holder of roughly half the high-bandwidth-memory market, sees no supply-demand balance before 2030, and its board has approved $38.30 billion of fab investment through 2031 56. Nvidia's−3.21% — Nvidia, down 3.21 percent today finance chief calls memory pricing "extreme" and "headed even higher into next year," and has guided gross margin down to a 71–72% floor while the bill lands 7.

Micron−4.50% — Micron, down 4.50 percent today cleared a $1 trillion valuation this year at 6.6 times forward earnings, and Morgan Stanley+0.55% — Morgan Stanley, up 0.55 percent today more than doubled its target to $1,050 5. The complex rallied into the news: Friday's close put Micron up 3.9% and SanDisk up 11% 3.

CXMT grew almost twice as fast as the market

The margin transfer The Inference traced in "Memory Is Eating the AI Boom" now has a challenger with production dates. CXMT's share of global DRAM revenue reached 9.5% in the second quarter, up from 7.6%, on revenue up 99.3% sequentially, in a market that itself grew 59.5% to $154.7 billion 34.

The growth is no longer only cheap phone chips. CXMT's server DRAM revenue passed its mobile revenue for the first time, and its 82% operating margin topped Samsung, SK Hynix and Micron 48.

Fourth, and climbing: CXMT took 9.5% of global DRAM revenue in Q2 2026, up from 7.6% a quarter earlier.3,4

Phones, not HBM, for now

The bulls have a fair answer: CXMT's new parts are LPDDR5X for handsets, not the HBM that carries the AI premium, and Samsung's and SK Hynix's inventories sit below 10 days 24. Citi still cut its Micron target to $1,150 on possible 2027 price softening 5.

30 September is the first reading

Micron reports fiscal Q4 on 30 September with high-bandwidth memory sold out for 2026 5. Watch two lines: whether CXMT's server share keeps climbing, and whether contract prices keep rising, since TrendForce already sees third-quarter increases slowing to 13–18% 4.

The paying side has names: Nvidia's guided margin floor is the AI builders absorbing the bill and passing part of it forward, and TrendForce reports PC and smartphone makers already struggle to absorb further increases 74. Whoever signs long contracts at today's prices carries the risk if CXMT's cheaper capacity turns the cycle. Every point of share CXMT takes is a point the shortage story has to buy back.

    Allegro MicroSystems launches a single-chip 48-volt power chip it says cuts the parts bill by up to half

    The A81481 power management chip is Allegro's bid for the steering and braking sockets that 48-volt wiring opens, turf Texas Instruments is also working. The stock fell 14.2% the day the chip arrived and has bounced since; the December quarter decides who is right.

    Cerebras filing names Flex and Sanmina to build a 10x ramp; Sanmina's inventory has doubled

    Sanmina never named the customer behind the second AI platform inside its fiscal 2027 guidance. Cerebras' November 12 SEC filing names Sanmina as a manufacturer scaling past 10x capacity by year end, and Sanmina's balance sheet is already carrying the cost.

    IonQ CFO Inder Singh quits eight days after a $173.8 million revenue quarter, no reason given

    The COO and CFO who signed IonQ's $173.8 million quarter left effective immediately, no reason given, while analysts' earnings estimates for the year are being slashed. Holders get one clean test: Gary Merrill's first guidance with fourth-quarter results in February.

    TSMC's board approved $1.5 billion of Anthropic and OpenAI equity, and joined the anchor book

    The foundry that sells wafers to every AI lab is now an anchor investor in Anthropic's $26 billion private placement, the same placement that funds the compute orders behind TSMC's $40.93 billion capacity expansion. Whether that expansion is cash-funded gets its first public mark when the IPO prices on November 18.

    Marvell expands its board to ten as its $115 billion Lumentum deal sits at a 19.7% spread

    Three new independent directors, none of them optical operators, will oversee an all-stock merger that cannot close before the first half of 2028. Marvell holders keep about 67% of the combined company and the regulatory risk; Lumentum holders take about 33% through a fixed ratio tied to Marvell's stock.

    Micron's Taiwan fab stays suspended after a union walkout, handing HBM capacity to Samsung and SK hynix

    The walkout leaves the fab stopped with no settlement date, and the HBM capacity it was meant to add by 2028 is capacity Micron's booked-up Korean rivals can sell instead. Micron, the smallest of Nvidia's three HBM4 suppliers at an estimated 17% share, reports in December with an 86% gross-margin guide to defend.
