Behind stock market king Chang Xin, are Xiaomi and NIO planning a fierce battle?

原文:在股王长鑫背后,小米和蔚来要开打算力战?

Summary of Key Points

On July 27th, Changxin Technology, a leading domestic manufacturer of storage chips, made its debut on the STAR Market, experiencing a surge in its stock price of 471% at opening, with a total market value reaching 3.31 trillion yuan (equivalent to the combined value of two Moutai bottles and exceeding that of Industrial and Commercial Bank of China), becoming the new “market value leader” among A-share companies. Xiaomi, NIO, and Chery each invested 158 million yuan in the strategic placement of Changxin’s shares (with a lock-up period of 18 months). This move reflects the collaborative needs of these three parties with Changxin within the industrial chain: geographical proximity, the promotion of Anhui’s industrial development strategy, and the desire of automakers to ensure supply chain security. However, there are also risks associated with the cyclical nature of the DRAM industry and the uncertainty of preferential supply rights. Essentially, this is a battle for control over the supply of core storage chips in the era of smart vehicles.

I. Changxin Technology: Why Did It Become the “Market Value Leader” Among A-share Companies?

Changxin Technology is one of the few Chinese companies capable of mass-producing DRAM chips (the memory used to store data in smartphones and cars, similar to computer RAM) on its own, holding the fourth-largest share in the global DRAM market. The reason for its significant stock price increase upon listing is multifaceted: firstly, it has broken the monopoly held by Samsung, SK Hynix, and Micron, which together control 95% of the global DRAM market, making it a beacon of hope for domestic substitution; secondly, it is supported by core Chinese technology companies such as TCL, Alibaba Cloud, and ZTE, demonstrating strong industrial chain synergy; thirdly, there are high expectations for its growth in the field of automotive-grade storage chips (specifically designed for use in vehicles), as smart cars are increasingly becoming “supercomputers on four wheels” with growing memory demands.

II. Automakers Investing: Not Just Buying Stocks, but Securening Supply Chain Rights

The investments made by NIO, Chery, and Xiaomi amount to 158 million yuan each, with the primary goal of securing preferential supply rights rather than profiting from price differences (although they made a 700 million yuan profit on the first day of trading). The rationale behind this investment is as follows:

1. Geographical Advantage: Changxin’s headquarters are located in Hefei, and NIO’s factory there is just a 10-minute drive from Changxin’s wafer production facility; Chery’s local subsidiary is also nearby. The verification process for automotive-grade chips involves testing under extreme conditions such as high temperatures and vibrations, so being geographically close facilitates quick problem resolution (for example, if an issue is detected at 9 AM, personnel can be on-site by 10 AM, reducing communication costs by half).

2. Anhui’s Industrial Strategy: Anhui is promoting a strategy that integrates chip production, display technology, equipment, and new energy vehicles, aiming to create a closed-loop ecosystem between local chip companies and automakers. As a leading chip manufacturer, Changxin, along with local automakers like NIO and Chery, is participating in this initiative.

3. Essential Need for Automakers: Although automakers are developing their own computing chips (such as NIO’s Shenji and Xpeng’s Turing), they still rely on externally sourced storage chips. With the global DRAM market dominated by a few companies, any shortages or price increases (as Li Bin mentioned, memory prices could become the biggest cost pressure by 2026) can be mitigated by having closer ties with suppliers like Changxin, effectively securing a priority supply position.

III. Xiaomi’s Unique Role: From Traditional Mobile Customer to New Automotive Partner

Xiaomi is different from NIO and Chery in that it has long been a customer of Changxin’s products (using Changxin’s LPDDR memory in several of its flagship smartphones). This investment marks an upgrade from supply chain cooperation to a strategic partnership. With the mass production of Xiaomi vehicles, demand for automotive-grade DRAM will surge, especially for intelligent cockpits and autonomous driving systems that require large amounts of memory. Xiaomi’s combined purchasing power across both smartphone and automotive sectors may give it a higher priority in securing supply from Changxin.

IV. Risks Behind the Excitement: Beyond the Immediate Profit

1. Cyclical Nature of the DRAM Industry: The chip industry experiences boom-bust cycles, and Changxin’s performance during the previous downturn was average. The current market value of 3.31 trillion yuan reflects the market’s highest expectations for its future growth; however, any industry fluctuations could lead to a correction in stock prices.

2. Uncertainty of Preferential Supply Rights: If Changxin faces production capacity constraints, it is unclear whether it will prioritize supplying companies that produce hundreds of millions of units per year (such as Xiaomi) over those that produce only tens of thousands.

3. Verification of Automotive-grade Chips: Although Changxin’s automotive-grade chips have been tested in NIO’s vehicles, large-scale production and quality assurance still need to be verified.

V. The Era of Computing Sovereignty: A Critical Issue for Automakers

Smart cars have evolved from being simple “four-wheeled sofas” to advanced “supercomputers,” with core chips (for computing power and storage) becoming key competitive factors. The investments by NIO, Chery, and Xiaomi in Changxin are essentially attempts to secure control over these critical components. Whoever masters the stable supply of these essential parts will gain a significant advantage in the future race for smart vehicle technology. This battle for dominance has just begun.
