Enflame Technology, a Tencent-backed AI chipmaker, saw its shares surge 188% on its first day of trading on the Shanghai Stock Exchange on September 11, giving the company a market capitalization of 176.4 billion yuan, or approximately $26.3 billion5,6.
The IPO raised 6.12 billion yuan, roughly $912 million2. Enflame opened at 410 yuan, up from an issue price of 142.18 yuan, and closed approximately 179% above the offer. Sources varied on the precise first-day gain: the South China Morning Post reported a 188% surge, while Business Insider and China Money Network cited a roughly 200% increase1,3.
Retail demand was extreme. Individual investors ordered 6,109 times more shares than Enflame had made available in its retail allocation. The listing is described as part of a broader wave of Chinese AI chip IPOs.
Enflame is one of a group referred to as China's "four" major domestic challengers to Nvidia. The company is backed by Tencent Holdings. The South China Morning Post framed the debut as reflecting "continued investor appetite for domestic AI chip champions" amid U.S. export restrictions on advanced semiconductors.
ANALYSIS The gap between Enflame's roughly $912 million IPO raise and its $26.3 billion closing-day market cap reflects the intensity of demand for domestically developed AI accelerator companies trading on Chinese exchanges.
The 6,109-times retail oversubscription stands out even by the standards of recent Chinese tech IPOs, underscoring how concentrated investor interest has become around AI chip plays listed onshore.
Note on sourcing: SRC-002 lists the IPO raise as "about $912 billion" in its text, which is inconsistent with the 6.12 billion yuan figure in the same sentence; the correct conversion, corroborated by other sources, is approximately $910–$912 million.
