Enflame wins STAR Market approval to raise 6 billion yuan for AI chips

China's securities regulator approved the STAR Market IPO of Shanghai Enflame Technology Co., a Tencent-backed AI chip developer that plans to raise 6 billion yuan ($883 million), adding to a surge of domestic semiconductor listings as Beijing pushes for technological self-reliance.

"The listing of these hard-tech companies will guide social capital toward strategic emerging industries, forming a virtuous cycle of technology, capital and industry," Hu Qimu, a professor at the Maritime Silk Road Institute of Huaqiao University, said.

Enflame reported revenue of 9.9 billion yuan in 2025, up 37% from 7.22 billion yuan a year earlier, while its net loss narrowed to 11.64 billion yuan from 15.1 billion yuan. The company has accumulated more than 43 billion yuan in losses over three years, driven by research and development spending that exceeded revenue each year. Its R&D investment totaled 11.35 billion yuan in 2025, or 115% of sales.

The approval marks a milestone for China's homegrown AI chip sector, where four startups — Enflame, Moore Threads, Mthreads and Biren Technology — known as the "Four Dragons of Domestic GPUs" are all pursuing public listings. Enflame's extreme reliance on Tencent, which holds a 20.26% stake and accounted for 83.79% of its 2025 revenue, raises questions about the company's ability to operate independently in a market where Nvidia's dominance remains unchallenged.

Enflame chose a different technical path from most of its domestic peers. Rather than adopting the GPGPU (general-purpose graphics processing unit) architecture used by Nvidia and AMD, the company developed its own DSA (domain-specific architecture) and a software platform called Yusuan. The approach avoids direct competition with Nvidia's CUDA ecosystem but requires heavy upfront investment in software tooling and developer adoption — a barrier that has kept many DSA-based chip companies from gaining traction.

The company plans to use the IPO proceeds to fund development of its fifth- and sixth-generation AI chips, according to its prospectus. Enflame focuses on cloud-based AI chips and intelligent computing clusters, targeting the inference market where demand is surging as Chinese companies deploy large language models.

Tencent Dependency and Financial Pressures

Enflame's financial position shows the strain of its high-investment strategy. The company's inventory reached 8.63 billion yuan at the end of 2025, nearly matching its full-year revenue, while its allowance for bad debts on accounts receivable climbed to 24.76%. Operating cash flow remained negative for three consecutive years, indicating the company relies on external funding to sustain operations.

Tencent is both Enflame's largest shareholder and its dominant customer — a concentration risk that few listed chip companies carry. The relationship provides a guaranteed revenue stream but limits Enflame's ability to diversify its customer base and demonstrate market-driven demand.

A Wave of Chinese Chip Listings

Enflame joins a growing queue of Chinese semiconductor companies seeking public funding. CXMT, a leading memory chipmaker, filed its STAR Market prospectus in July, planning to raise 29.5 billion yuan in what would be the second-largest IPO on the exchange. Iluvatar CoreX, another GPU developer listed in Hong Kong in January, has seen its shares surge 310% above the IPO price and raised an additional HK$7 billion through a placement this month.

The China Securities Regulatory Commission in June expanded STAR Market listing standards to include AI companies, signaling official support for capital formation in strategic technology sectors. The policy shift has accelerated IPO timelines: Enflame moved from filing to registration approval in less than six months.

For investors, the question is whether Enflame can translate its regulatory win into sustainable commercial traction. The company's DSA architecture offers a differentiated approach in a market dominated by Nvidia's general-purpose GPUs, but without independent benchmarks or disclosed customer wins beyond Tencent, the technology's competitiveness remains unverified. Nvidia's H100 delivers 990 TFLOPS of FP16 performance on TSMC's 4nm process; Enflame has not disclosed comparable specifications for its cloud chips.
