CXMT debuts up 472% on Shanghai STAR, hits $489B market cap
TL;DR
- Hyperliquid perpetual futures implied a roughly $500B valuation before the Shanghai bell, meaning decentralized crypto markets provided earlier price discovery than the official exchange.
- A 200x oversubscription rate against a 6.73% free float means the $489B headline valuation is set by a thin slice of shares, deferring genuine price discovery.
- Analyst targets span the widest range seen on any major IPO this year: Nomura at 1,239% above the IPO price vs Morningstar at 72% above IPO but 68% below where shares actually opened.
A first-day pop of 472% is not the usual state of affairs, and yet that is what China's ChangXin Memory Technologies delivered on Monday, opening at 49.50 yuan against an 8.66-yuan offer price. The South China Morning Post reported that the trade valued the Hefei-based DRAM maker at roughly 3.31 trillion yuan, about $489 billion, making it the most valuable company listed on the mainland Chinese market.
The scale of the raise matters as much as the pop. CXMT pulled in up to 66.6 billion yuan, eclipsing the 53.2 billion yuan that Semiconductor Manufacturing International Corporation raised on the STAR Market in 2020. That is a lot of capital being drawn out of the rest of the Chinese tech tape in one event, which is why the China Securities Regulatory Commission held pre-listing meetings with market participants over concerns the debut would draw funds away from other Chinese technology stocks, and pledged to enhance the market's inherent stability.
Beyond the mainland, CXMT is now positioned as the world's fourth-largest DRAM manufacturer behind Samsung, SK Hynix and Micron, and the demand story the market is pricing in runs through AI. Every hyperscaler build-out needs memory. A Chinese national champion with a state audience and this much fresh capital is a different kind of competitor than the underfunded challenger CXMT was a couple of years ago. The same day, our coverage had Apple pressing to source CXMT memory over resistance from US officials.
A first-day valuation is not a settled valuation, especially when a regulator is actively worrying out loud about capital concentration. The reporting does not detail how CXMT will deploy the proceeds or whether it can meaningfully break into high-bandwidth memory, the AI-accelerator segment where the Korean and US incumbents have the lead. Take the market-cap crown as accurate for today, and treat what CXMT does with the money as the actual story worth tracking through the back half of 2026.
