Enflame IPO Draws 6,109x Demand as China's AI Chip Fever Peaks

Shanghai-based AI chipmaker Enflame (燧原科技) has become the latest symbol of China's domestic-chip capital frenzy. On September 2, 2026, the STAR Market company completed its IPO subscription with preliminary effective online demand of roughly 6,109 times the shares on offer — an oversubscription level that triggered the automatic clawback mechanism and instantly put the company among the most sought-after Chinese tech listings in years.

The headline multiple measures the online tranche only, and the mechanics deserve care. The preliminary online effective subscription multiple of about 6,109.34x — calculated against the initial online allocation of 6.89 million shares — exceeded the 100x threshold, triggering a clawback that raised the online allocation to 10.33 million shares. On that post-clawback basis, online demand works out to roughly 4,073 times, the figure used by Bloomberg and other international outlets. Either way, the final online winning rate was minuscule: 0.02455315 percent, across 7.03 million effective online accounts that placed valid bids for 42.07 billion shares.

A Tencent-backed chipmaker, still burning cash

Enflame priced its IPO at 142.18 yuan per share, raising gross proceeds of 6.12 billion yuan (about $858 million) — 5.81 billion yuan net — and implying a post-IPO valuation near 61.19 billion yuan. The company lists on the STAR Market's growth tier with an "-U" suffix, marking it as not yet profitable. Its prospectus shows revenue climbing from 301 million yuan in 2023 to 722 million in 2024 and 990 million in 2025, with first-half 2026 guidance of 1.06 to 1.15 billion yuan, up 258 to 289 percent year on year. Net losses have narrowed but persist — 1.67 billion, 1.51 billion and 1.16 billion yuan across 2023–2025 — and accumulated losses stood at 4.44 billion yuan at the end of 2025.

The company's product story rests on its Suiso (邃思) family of cloud AI chips — four generations and five chips built around a self-developed GCU-CARE compute unit and GCU-LARE interconnect, running on its own TopsRider (驭算) software stack that does not depend on CUDA. Chairman Zhao Lidong told the roadshow that demand for compute is growing explosively and that "the rise of domestic AI chips is entering its golden period."

That positioning, however, comes with concentration risk that the prospectus does not hide: Tencent holds a 20.26 percent stake as the largest external shareholder and is also the largest customer, accounting for 83.79 percent of 2025 revenue — up from 33.34 percent in 2023. Tencent's affiliated entity also took a 174.71万-share strategic placement worth 248 million yuan with a 36-month lockup.

A market built on scarcity and substitution

The 6,109x demand says less about Enflame's fundamentals than about the structure of China's AI-chip market in 2026. US export controls have made domestically produced AI accelerators a strategic necessity, and the STAR Market's rules — no price limits for the first five trading days and a small initial float — turn every hot listing into a lottery. The precedents are vivid: Moore Threads closed up 425.46 percent on its December 2025 debut, and MetaX (沐曦股份) closed up 692.95 percent in the same month. Cambricon, the sector bellwether, became the STAR Market's first trillion-yuan company on June 30, 2026 after an 11-month, 363 percent run — prompting an unusual same-night risk warning from the company itself.

Regulators are visibly torn between fostering the sector and cooling speculation. At the June Lujiazui Forum, CSRC chairman Wu Qing pledged to strictly investigate "hype, concept-chasing and market manipulation in the name of technology," and the regulator has levied penalties on several companies for AI concept speculation this year. Yet policy has also opened the door wider: in June 2026 the STAR Market's fifth listing standard was extended to loss-making AI firms, and sector guidance was issued for AI large-model listings — precisely the tailwind that let an unprofitable Enflame reach the market with a 61.8x price-to-sales ratio that, notably, still sits below the roughly 93.5x average of its listed peers.

What the frenzy does and does not tell us

The oversubscription is, in effect, a measure of share scarcity and substitution demand rather than conviction about any single company's path to profit. Enflame still loses money, earns the large majority of its revenue from one shareholder-customer, and carries a gross margin that trails its listed peers. What the 6,109x figure does prove is that China's capital markets can now absorb AI-chip companies at scale — and that retail investors, denied Nvidia's latest parts by export policy, are treating every domestically designed accelerator as a proxy for the entire sector's future. The listing result is due on September 4; the longer test is whether the sector's valuations can be justified by revenue growth that is real but still narrow.
