Tencent-backed AI chipmaker Enflame closes up about 179% in its Shanghai STAR Market debut after a $911 million raise

Enflame Technology, the Shanghai AI chip designer backed by Tencent, raised 6.12 billion yuan, roughly $911 million, in its listing on the Shanghai Stock Exchange's STAR Market. The deal priced at 142.18 yuan a share across 43.04 million shares, against a pre-trading valuation of about 61 billion yuan. Retail demand was heavy, with the offer oversubscribed 4,073 times.

The debut was one of the year's sharpest. Enflame closed its first session up about 179%, after peaking intraday at 475 yuan, a gain of 234% from the offer price. That left the market capitalization near 170.9 billion yuan, roughly $25.5 billion, at the close. Wire coverage carried a higher intraday figure of about 206%, which corresponds to a different snapshot during the session rather than a conflicting number.

TCEHY is the commercially important shareholder here, and on both sides of the ledger. Tencent holds more than 20% of Enflame as its largest external backer, and it also accounted for more than 80% of Enflame's 2025 revenue. That concentration is the central risk in the equity story: a supplier whose largest customer is also its largest shareholder has a revenue line that is not yet independently demonstrated. Other disclosed backers include ZhenFund, Summitview Capital, Primavera Capital, CITIC PE, China's National Social Security Fund and the China IC Industry Investment Fund.

The wider read is about substitution rather than parity. Enflame's positioning is as a domestic alternative for Chinese AI compute under US export restrictions, and the company is not yet profitable. Nothing in the listing coverage claims its parts match the performance of leading Western accelerators, so a first-day pop of this size is a scarcity premium on domestic AI silicon exposure more than a verdict on the technology. What to watch is whether revenue diversifies away from Tencent in the first reported periods as a public company.
