Enflame Technology, a Shanghai-based AI chip developer backed by Tencent, has submitted its application for an initial public offering on Shanghai's STAR Market, seeking to raise 6 billion yuan ($830 million). The move comes as China's domestic AI chip sector intensifies competition amid a wave of listings, with Tencent accounting for over 70% of the company's sales in the first nine months of 2025.

The company, which sold 38,800 AI accelerator cards and modules in 2024, holds approximately 1.4% of China's AI accelerator card market, positioning it among the leading domestic manufacturers. Tencent Technology (Shenzhen), the company's largest shareholder with a 19.95% stake, also emerged as its top customer in 2025, representing 71.84% of sales through both direct and AVAP model transactions.

Enflame's IPO filing follows similar moves by rivals including Kunlun Core, which submitted a confidential listing application to Hong Kong's stock exchange on January 1, and Alibaba's Pingtou Ge, which is reportedly considering a restructuring and IPO. The competitive landscape underscores the strategic importance of AI chips as Chinese tech giants seek alternatives to U.S. semiconductor suppliers.

Management expects the company to reach breakeven as early as 2026, following cumulative losses of 4.165 billion yuan ($575 million) as of September 2025. The IPO proceeds will fund research and development of fifth and sixth-generation cloud AI chip products.

Heavy Reliance on Tencent Raises Concentration Concerns

Enflame's customer concentration presents both opportunities and risks for potential investors. During 2022, 2023, 2024, and the first nine months of 2025, sales to the company's top five customers accounted for 94.97%, 96.50%, 92.60%, and 96.41% of total revenue respectively. Tencent's share of sales surged from 8.53% in 2022 to 71.84% in the first nine months of 2025, combining direct sales and AVAP model transactions.

The AVAP model involves sales to server manufacturers designated by Tencent, including customers identified as A, D, J, and L in the prospectus. This arrangement reflects the deep integration between Enflame and Tencent's AI infrastructure, which began in 2019 and has evolved through multiple product generations.

The company acknowledged that high customer concentration is likely to persist in the near term, given that China's internet sector remains the primary source of AI computing demand. However, Enflame is actively diversifying its customer base by participating in national "East Data, West Computing" hub projects, deepening cooperation with domestic network operators, and expanding into vertical industry applications.

Financial Performance Shows Revenue Growth Amid Mounting Losses

Enflame generated revenue of 90 million yuan, 301 million yuan, 722 million yuan, and 540 million yuan in 2022, 2023, 2024, and the first nine months of 2025 respectively. Despite revenue growth, the company reported net losses of 1.116 billion yuan, 1.665 billion yuan, 1.510 billion yuan, and 888 million yuan over the same periods, while research and development expenses totaled 988 million yuan, 1.229 billion yuan, 1.312 billion yuan, and 890 million yuan.

The company's gross margin improved from 78.07% in 2022 to 36.23% in the first nine months of 2025, though it remains below comparable companies' average levels. More than 99% of revenue originated from mainland China across all reporting periods.

Operating cash flow remained negative throughout the reporting period, at -987 million yuan, -1.209 billion yuan, -1.798 billion yuan, and -770 million yuan respectively, primarily due to strategic inventory buildup of key materials. Inventory balances increased from 311 million yuan at the end of 2022 to 1.148 billion yuan by September 2025.

As of September 2025, accumulated deficits reached 4.165 billion yuan on a consolidated basis and 1.864 billion yuan for the parent company. The company employs 658 research and development personnel, representing 76.51% of total staff, and holds 262 domestic invention patents.

Product Portfolio Targets Nvidia Alternative with Domestic Supply Chain

Enflame has developed four generations of architecture across five cloud AI chip models since its founding in March 2018. The company plans to launch its fourth-generation AI inference cards and ESL32/64 super-node clusters in 2026, followed by fifth-generation cloud AI chips, training-inference integrated cards, and inference cards in 2027, and sixth-generation products in 2029.

The company's product ecosystem encompasses AI chips, AI accelerator cards and modules, intelligent computing systems and clusters, and the TopsRider AI computing and programming software platform. Unlike rivals that follow Nvidia's CUDA ecosystem, Enflame developed proprietary GCU-CARE accelerated computing units and GCU-LARE inter-chip high-speed interconnection technology, comparable to Nvidia's Tensor Core and NVLink technologies.

Enflame has established partnerships with over 100 companies across the AI industry chain and adapted more than 200 mainstream large language models including DeepSeek, Qwen, and GLM. The company has delivered thousand-card and ten-thousand-card intelligent computing center projects during the reporting period and is collaborating with partners to build super-ten-thousand-card cluster solutions supporting pre-training of models with hundreds of billions to trillions of parameters.

The company emphasized its commitment to developing a fully domestic supply chain, achieving "local design + local manufacturing + local testing + local EDA/IP + local models + local applications" to ensure industrial autonomy from research to application. According to Goldman Sachs Global Investment Research projections, non-GPGPU chips' share of AI server shipments in China will rise from 36% in 2024 to 45% by 2027.

AMD Veterans Lead Company as Sector Valuations Soar

Chairman and CEO Zhao Lidong and Chief Operating Officer Zhang Yalin, both AMD alumni, collectively control 28.14% of Enflame through direct holdings and employee stock ownership platforms. Zhao, a 1985 graduate of Tsinghua University's electronics department, spent over 20 years in Silicon Valley working at S3, Juniper Networks, and AMD, where he served as senior director of the computing business unit and participated in establishing AMD's China R&D center.

Zhang, who holds a bachelor's degree from Fudan University's electronics department, worked as AMD China R&D center technical director and led development of multiple chips including the custom XBOX-ONE series processor for Microsoft. Multiple senior executives including Vice Presidents Chai Jing, Gao Xiaotian, and Zhang Min also previously worked at AMD's Shanghai operations.

Beyond Tencent and the China Integrated Circuit Industry Investment Fund Phase II (National Big Fund II) with 4.32%, shareholders include Meitu with 1.31%. The company's registered capital stands at 387 million yuan.

Domestic competitors include non-GPGPU architecture manufacturers such as Huawei HiSilicon, Cambricon Technologies, and Kunlun Core, alongside GPGPU architecture manufacturers including Hygon Information, Moore Threads, MetaX Integrated Circuits, Iluvatar CoreX, and Biren Technology. As of January 22, Cambricon, Moore Threads, MetaX, Biren, and Iluvatar held market capitalizations of 570.5 billion yuan, 295.5 billion yuan, 239.1 billion yuan, 88.4 billion Hong Kong dollars, and 54.7 billion Hong Kong dollars respectively. Based on Hurun Research Institute's June 2025 Global Unicorn List, which valued Enflame at 20.5 billion yuan, a successful STAR Market listing could push its valuation into the hundred-billion-yuan range.
