- Shanghai startup becomes the latest leading domestic AI chipmaker to reach public markets
- Its alternative chip architecture offers a different challenge to Nvidia’s CUDA ecosystem
Chinese AI chipmaker Enflame Technology (燧原科技) has received regulatory approval to proceed with its IPO on Shanghai’s Nasdaq-style STAR Market, becoming the last of China’s so-called “AI chip four tigers” to secure a place in the capital markets.
The approval, announced by the China Securities Regulatory Commission on July 9, follows the listings of Moore Threads (摩尔线程), MetaX (沐曦股份) and Biren Technology (壁仞科技).
Together, the four companies represent China’s ongoing efforts to build a domestic alternative to Nvidia in AI computing.
Founded in 2018, the Shanghai-based company develops AI accelerators for cloud computing and has built a full-stack portfolio spanning AI chips, accelerator cards, computing clusters and software.
It plans to raise 6 billion yuan ($840 million) from the offering to develop its fifth- and sixth-generation processors and expand its software ecosystem.
Revenue more than tripled between 2023 and 2025 to 990 million yuan, while losses narrowed as commercial deployments accelerated.
A different path to AI chips
Unlike its three peers, Enflame does not build general-purpose GPUs compatible with Nvidia’s CUDA software platform.
Instead, it has adopted a domain-specific architecture (DSA), designing chips specifically optimized for AI workloads rather than general computing.
The company has also built its own software platform, allowing customers to operate independently of CUDA.
The trade-off is familiar across the AI chip industry. Specialized architectures can deliver higher efficiency and lower inference costs, but often struggle to match the breadth of software support enjoyed by Nvidia’s ecosystem.
The approach mirrors strategies adopted by major US technology companies including Google, Amazon and Microsoft, all of which have developed custom AI accelerators alongside GPUs.
Deep Tencent ties
Enflame’s commercialization strategy has centered on a close partnership with tech behemoth Tencent.
Tencent is both the company’s largest shareholder, with a combined stake of more than 20%, and its biggest customer.
Nearly 84% of Enflame’s revenue in 2025 came from Tencent, where its chips power inference clusters supporting products including the Hunyuan foundation model and Yuanbao AI assistant.
The relationship has accelerated product deployment but also created significant customer concentration risk.
Enflame acknowledged in its prospectus that sales to Tencent are priced below those to unrelated customers under the strategic partnership, contributing to margins below some industry peers.
Why it matters globally
Enflame’s IPO approval marks another milestone in China’s bid to build a self-sufficient AI semiconductor industry amid tightening US export controls.
It also highlights a broader shift in AI computing. Rather than converging around a single GPU architecture, the industry is increasingly embracing multiple chip designs optimized for different workloads, particularly AI inference, where cost and energy efficiency are becoming as important as raw computing performance.
The challenge for Enflame will be expanding beyond its anchor customer while continuing to build a software ecosystem capable of competing with Nvidia’s vast developer community.
Its success—or failure—will offer an early test of whether specialized AI chips can gain broad commercial traction outside proprietary ecosystems.
