China's CXMT Memory Chip Maker Announces $8.6B Shanghai IPO

CXMT IPO Shanghai STAR Market DRAM market share state-backed semiconductor ByteDance deal

ChangXin Memory Technologies (CXMT Corp) is set to list on Shanghai's STAR Market on July 27, 2026, raising roughly 57.9 billion yuan (about $8.6 billion) and achieving a post‑IPO valuation of around 579 billion yuan ($85 billion). The offering, the largest IPO in Asia for 2026, will sell 6.69 billion shares, with an overallotment option that could increase the pool to 7.69 billion shares.

CXMT, the world's fourth‑largest DRAM producer with an estimated 7.7 % market share in 2025, reported nearly $7.5 billion in revenue in the first quarter, a 700 % increase year‑over‑year, and posted its first profit. State‑affiliated investors own about 36 % of the company, reflecting significant government backing. The firm also secured a deal with ByteDance valued at over $7 billion.

Separately, cryptocurrency exchanges introduced USDT‑settled perpetual contracts on CXMT before the official listing, trading about $19 million in a 24‑hour window. Analysts link the surge in CXMT activity to a broader memory‑chip boom driven by AI workloads, which has lifted semiconductor memory revenue five‑fold and profits ten‑fold worldwide.
