Li Auto Carves Its 5nm Driving Chip Into a Two-Month-Old Company Worth 16.6 Billion Yuan

Li Auto has put a price on four years of in-house silicon. On October 16 the Chinese automaker announced that Shanghai Mach Core Technology, the entity holding its chip and domain-controller business, signed a first-round equity financing agreement worth 1.63 billion yuan (about $229 million). The remarkable part is the paperwork: Mach Core was incorporated on August 12, making it a two-month-old company valued at 16.63 billion yuan post-money, roughly $2.3 billion.

The round's structure shows Li Auto hedging its own conviction. Li Auto subscribes 1 billion yuan through a wholly owned subsidiary to keep control; outside investors - Hangzhou Jingtao, BlueRun Ventures China and Huaye Tiancheng at 200 million yuan each, plus MiraclePlus at 25 million - add 625 million at 23.35 yuan per unit of registered capital, implying a 15 billion yuan pre-money valuation. Hangzhou Jingtao also holds an option, exercisable before December 31, to subscribe up to another 500 million yuan, which would lift the post-money valuation to 17.1 billion yuan and dilute Li Auto from 100 percent to about 74 percent. Li Auto says it will retain a controlling stake either way.

What investors are actually buying is a chip already in production. The Mach M100 is what the company calls the world's first dynamic-dataflow AI chip for vehicles, built on a 5nm automotive-grade process and rated at 1,280 TOPS per unit. It is already running in the new L9 and L8 and the next-generation L6. Li Auto CTO Xie Yan has framed the scale in physical terms: two M100s per car add up to about 800 square millimeters of silicon, versus roughly 100 square millimeters for a high-end phone chip - one intelligent car consumes the silicon area of about eight flagship phones.

The spinout is a response to the economics underneath. China's passenger-car market is in a deep slide: retail volume fell 20.8 percent in the first eight months of the year, auto industry profit margins ran at just 3.6 percent through July, and manufacturing profit fell 16 percent over the same eight months. Against that, Li Auto's research spending has climbed - 11.3 billion yuan in 2025, a record 10.06 percent of revenue, with AI work absorbing about half - and 5.5 billion yuan in the first half of 2026. A chip business that can sell outside the car fleet turns a cost center into a revenue line.

The company is explicit about where the money goes: continued development of chips and domain controllers, and pushing products to external customers, "especially non-automotive sectors." Mach Core's full-stack pitch - dynamic-dataflow silicon co-designed with its own compiler, algorithms and operating system - is aimed at any workload that needs high compute per watt at the edge, and the automotive fleet now serves as the reference customer rather than the only one.

Li Auto is not alone in monetizing its silicon. XPeng opened its own intelligent-vehicle technology portfolio, XPENG AI ENGINEERING, to global partners at the Paris show on October 13, covering platforms, driver-assistance, AI boxes, chips and toolchains. The pattern across China's new-energy automakers is the same: as car margins compress, the AI stack built for the car becomes a product in its own right.

The 16.6 billion yuan valuation is, in the end, a wager that dynamic-dataflow architecture has a market beyond Li Auto's own assembly lines. The company has two things working in its favor - silicon already shipping at volume, and a parent that remains the anchor customer. What it does not yet have is a disclosed external order book, and that is the number that will decide whether two months of corporate existence was worth $2.3 billion.
