CXMT’s $8.6bn IPO sets up STAR Market debut

ChangXin Memory Technologies (CXMT) has completed a major initial public offering in Shanghai, raising 57.92 billion yuan, or about $8.6 billion. The company sold 6.69 billion shares at an offer price of 8.66 yuan per share. If the underwriters’ overallotment option is fully exercised, total proceeds could rise to 66.61 billion yuan. CXMT is scheduled to start trading on Shanghai’s STAR Market on Monday, 27 July 2026.

The offering positions CXMT as one of the largest recent listings on the STAR Market. The deal size underlines both the capital needs of a large memory chip producer and the depth of domestic demand for semiconductor-related equity. The IPO also formalizes a public-market valuation baseline against which other indications of CXMT’s value can be compared.

Local government-linked investors in Hefei hold about 36.8% of CXMT. At the IPO offer price, this stake is valued at roughly 213 billion yuan, or around $31.5 billion. The sizeable holding illustrates the scale of state-backed participation in the company’s capital structure. It also highlights how much value is now tied to CXMT’s public-market performance for regional stakeholders.

With CXMT recognized as the world’s fourth-largest DRAM manufacturer, behind Samsung, SK Hynix and Micron, the offering gives public investors direct exposure to a major player in the global memory industry. The IPO valuation provides a reference point for assessing the worth of this position within both domestic and international chip markets.

Ahead of the Shanghai debut, perpetual-futures contracts linked to CXMT traded on a crypto platform at levels that implied a much higher valuation than the IPO price. These contracts recently changed hands near $6.35 per share and had earlier peaked around $8.60 per share. At those levels, the implied market capitalization was about $425 billion, or roughly 2.9 trillion yuan.

This gap between the implied valuation in derivatives markets and the equity valuation at the IPO price points to strong speculative interest. It also sets up a contrast between expectations embedded in crypto-linked trading and the price discovered through the onshore share sale. How the stock trades once it lists will show whether public equity investors move closer to the derivatives-implied levels or remain aligned with the IPO pricing.

CXMT’s status as the world’s fourth-largest DRAM maker means its listing comes at a time when memory chips are a central component of global technology supply chains. The company’s scale provides context for the size of its capital raise and the attention its IPO has received. The public float created by the sale of 6.69 billion shares increases the visibility of a key Chinese memory producer in global markets.

The IPO proceeds give CXMT significant financial resources as it competes with established international peers. For investors, the listing offers a new way to access growth and volatility in the memory sector through the Shanghai market. The interaction between domestic demand, state-linked ownership and speculative interest in offshore derivatives will help shape CXMT’s trading profile once its shares begin changing hands.
