Biren AI Chipmaker Shares Jump 100% on HK's First 2026 IPO
By Reuters | 01 Jan, 2026

China's policy support for rapid buildout of domestic AI capacity provides strong impetus for AI chip stocks.

Shares of Chinese AI chip designer Shanghai Biren Technology more than doubled on their Hong Kong debut on Friday, kicking off the financial hub's first listing of 2026 with a bang.

Biren shares opened at HK$35.70 each, above the offer price of HK$19.60, and rose as much as 119% to HK$42.88.

The strong debut follows a blockbuster year for Hong Kong's equity market in 2025 and heralds a wave of chip and AI offerings this year as China accelerates efforts to strengthen domestic alternatives in response to U.S. curbs on technology exports.

"Chinese AI startups are going public faster than U.S. giants thanks to supportive domestic policy, clear paths to revenues from enterprise customers, and most importantly, a valuation small enough for the current IPO market," said Winston Ma, an adjunct professor at NYU School of Law and former head of North America for CIC, China’s sovereign wealth fund.

"The successful trading (so far) of AI startups illustrate a distinct AI development tracks: rapid public deployment in China focused on integration with industries, versus slower, highly controlled private development in the US focused on foundational breakthroughs."

Biren raised HK$5.58 billion ($717 million) by selling 284.8 million H shares at HK$19.60 each, the top of a marketed range.

Institutional demand was nearly 26 times the shares on offer, while the retail tranche was oversubscribed about 2,348 times, exchange filings showed.

At the offer price, Biren's market capitalisation stood at HK$46.9 billion, based on 2.396 billion shares outstanding.

Founded in 2019, Biren develops general-purpose graphics processing units (GPUs) and intelligent computing systems for artificial intelligence and high-performance computing. 

Its co-founders include Zhang Wen, a former president at SenseTime, and Jiao Guofang, who previously worked at Qualcomm and Huawei.

The company first drew attention in 2022 with its BR100 chip, touted as a domestic rival to advanced processors from U.S. AI leader Nvidia.

Biren will spend most of the IPO proceeds on research and development and commercialisation, its IPO prospectus showed.

The prospectus flagged risk from U.S. export controls after the group was added to Washington's Entity List in October 2023, which limits its access to certain technology.

It also cited competition and highlighted opportunities from China's push for tech self-sufficiency and policy support.

Cornerstone investors include 3W Fund, Qiming Venture Partners and Ping An Life Insurance, the prospectus showed.

CHINESE AI, TECH PIPELINE

As much as $36.5 billion was raised in Hong Kong from 114 new listings in 2025, the city's highest since 2021 and more than triple the previous year, showed LSEG data at year-end.

A wave of AI and semiconductor IPOs powered the comeback and is widely expected to propel deal flow in 2026.

Seven companies submitted A1 applications on January 1, HKEX filings showed. One was xTool Innovate which filed an application for a main board listing and appointed Morgan Stanley and Huatai Financial Holdings as overall coordinators. 

Separately, Chinese internet search leader Baidu said on Friday its AI chip unit Kunlunxin has filed a Hong Kong IPO application, confirming a Reuters report in early December.

Hong Kong's IPO pipeline includes AI startups and chipmakers, with Zhipu AI and Iluvatar CoreX to debut next on January 8.

"Is the HK AI IPO boom sustainable? It depends on whether global IPO investors, such as Middle East sovereign wealth funds, would buy in a shift of global AI dominance, prioritising immediate enterprise integration over long-term AGI research," Ma said.
