Micron gains 3% as Wall Street shrugs off CXMT's $8.5B IPO threat

Wall Street sees little near-term threat to Micron from China's new memory giant, whose $8.5 billion IPO funds a commodity-chip expansion that leaves the AI memory boom untouched.

Micron Technology shares rose more than 3% in premarket trading Monday as Wall Street assessed that China's newly public memory chip maker CXMT poses little near-term threat to the US company's AI-driven business. Nasdaq futures gained 1.57% and S&P 500 futures rose 0.93%, reflecting broad risk appetite across technology stocks.

CXMT, which began trading Monday on Shanghai's Star Market after raising about $8.5 billion in the largest-ever mainland IPO by a Chinese semiconductor company, holds just 7.6% of the global DRAM market, according to Omdia data. That share jumped from 4.7% in the prior quarter as CXMT absorbed demand the three incumbents could not supply during the AI-driven memory shortage. The listing valued the company at roughly $85 billion.

More than 98% of CXMT's revenue comes from conventional DRAM — the commodity chips used in servers and phones — leaving it with effectively no presence in high-bandwidth memory, the premium product stacked alongside AI accelerators. Samsung, SK Hynix and Micron held roughly 39%, 29% and 22% of the DRAM market, respectively, in the same period, and retain a multiyear technological edge in HBM, where the memory boom's richest profits are concentrated.

Micron's most recent quarter — the fiscal third period ended May 28 — showed revenue of $41.5 billion, more than quadrupling from $9.3 billion a year earlier. Net income reached $28.2 billion, and operating cash flow hit $25.4 billion, up from $11.9 billion just one quarter earlier. Management forecast fiscal fourth-quarter revenue of about $50 billion with a gross margin of roughly 86%, numbers that come from selling advanced memory into a shortage at prices commodity producers cannot touch.

CXMT's Expansion Plans Carry Long-Term Risk

What changes with Monday's listing is the supply picture further out. CXMT is directing its IPO proceeds toward production line upgrades and advanced DRAM development. The roughly $8.5 billion raised, which could approach $10 billion if the overallotment is exercised, nearly doubles what the company had originally planned to invest. Memory booms have historically ended when capacity built during the good years arrives all at once, and CXMT is now funded to add exactly that.

Micron's own history shows how violently the cycle can turn. The company posted a $5.8 billion net loss in fiscal 2023, when the last downturn crushed memory prices — and now earns nearly five times that in a single quarter. The same operating leverage cuts in both directions, and memory investors have seen both sides of it inside three years.

What This Means for Investors

At about $920 per share, Micron trades at a price-to-earnings ratio of about 21, a multiple that already treats the current earnings explosion as temporary. The market has never believed this boom would last forever, CXMT or no CXMT. The broader semiconductor sector also gained ground Monday, with Philadelphia Semiconductor Index futures pointing to a higher open, as investors focused on sustained AI infrastructure demand from companies like Nvidia — the largest buyer of HBM — rather than CXMT's near-term capacity additions.

For now, the competitive threat remains years away from touching the AI memory profits that drive Micron's current results. Investors will watch CXMT's advanced DRAM development timeline and any signs of HBM entry as the key indicators of when that calculus might change.
