Enflame, the Last of China's Four AI Chip Dragons, Opens Its $892 Million STAR Market IPO

Shanghai Enflame Technology — the Tencent-backed AI chip designer widely counted as the last of China’s “four little dragons” of AI silicon — has set Wednesday, September 2 as the date investors can subscribe to its initial public offering on the Shanghai Stock Exchange’s STAR Market. The company is selling 43.04 million new shares, about 10 percent of its post-listing equity, aiming to raise roughly 6 billion yuan (about $892 million) under the ticker 688801.

The subscription date, confirmed by Reuters on August 25, turns the lights on for the final act of a tightly-watched sequence. Moore Threads, Biren Technology, and MetaX — the other three “dragons,” the cohort of homegrown AI chipmakers Beijing is counting on to break its reliance on Nvidia — have all already listed on the STAR board and now trade well above their offer prices. Moore Threads, the standout, was up 425 percent after its December debut. Enflame is the last one out the door, and arguably the most interesting test of all.

Backer and buyer at once

Founded in Shanghai in 2018 by former AMD engineer Zhao Lidong, Enflame’s defining feature — and its defining risk — is Tencent. The tech giant owns roughly 20 percent of the company and bought about 84 percent of its revenue in 2025, up from around 38 percent a year earlier. Nearly 84 out of every 100 yuan Enflame earns comes from a single shareholder-customer.

That relationship cuts both ways. Tencent effectively pre-funds Enflame’s roadmap with purchase orders, which is how a startup holding barely one percent of China’s AI chip market manages to ship advanced silicon at all. The company says Tencent’s demand has “far exceeded” what it can supply. But a chipmaker that leans on one client for most of its sales is exposed if that client’s priorities shift, and the relationship already squeezes Enflame’s pricing. It is also deeply unprofitable: cumulative losses run to about 4.29 billion yuan (roughly $600 million) over three years, though the annual loss is narrowing, and revenue is expected to more than triple year-on-year to 10.6–11.5 billion yuan in the first half of 2026.

Real products, not slideware

Unlike some of its peers, Enflame has shipping hardware. Its latest accelerator packs 144GB of on-chip memory — a serious figure in an era when memory capacity, not raw FLOPS, often decides whether a training cluster is usable — and an earlier model shipped in the tens of thousands of units. The IPO prospectus allocates the 6 billion yuan primarily to R&D and industrialization of its fifth- and sixth-generation AI cloud chips plus the surrounding software stack.

That roadmap matters more than the raise itself. With US export controls choking off Nvidia’s best hardware, and a $295 billion state plan to build data centers that lock Nvidia out, Beijing needs domestic substitutes that exist beyond press releases. Enflame still trails Huawei and a now-profitable Cambricon at home. The fifth and sixth generations are its chance to close the gap.

A referendum priced in advance

Investors are underwriting the bigger story rather than the balance sheet. STAR-board rules were loosened last year specifically to let loss-making hardware firms list, and the wave of AI-chip floats that followed has been received enthusiastically — which is why Enflame can raise nearly $900 million while carrying $600 million in accumulated losses and a customer list of essentially one.

That makes the float a referendum. Its pricing and subscription demand will show how much conviction Chinese institutions really have in the AI-chip-independence story, and whether that conviction survives a hard look at the concentrated-revenue model. If Enflame debut performance echoes its three fellow dragons, expect the “four little dragons” cohort to be enshrined as the public face of China’s answer to Nvidia. If it stumbles, the single-customer dependency becomes the narrative overnight.

Watch September 2. The order book will tell you what Beijing’s chip independence is worth — priced to the yuan.
