Baidu Kunlunxin IPO
Baidu's chip subsidiary Kunlunxin filed on January 1, 2026, a confidential listing application in Hong Kong. This is a clear move towards a spin-off and separate IPO. Baidu justifies the planned spin-off by wanting to make Kunlunxin independently visible, attract investors focused on AI chips, and broaden funding channels.
The filing was made on a confidential basis with the Hong Kong Stock Exchange (HKEX) to list Kunlunxin's H-shares on the Main Board. The possibility of a “confidential filing” in Hong Kong was created by the Technology Enterprises Channel (TECH) launched by HKEX and SFC in 2025 which explicitly provides a new option for confidential filings for biotech and specialist technology listings.
After the spin-off is completed, Kunlunxin is to remain a subsidiary of Baidu. Regulatory conditions include HKEX approvals and a filing with the China Securities Regulatory Commission.
Valuation and Financing
Kunlunxin's latest valuation is estimated at 21 billion yuan (around 3 billion US dollars), based on a funding round. In this round, Kunlunxin raised "over 2 billion yuan", from, among others, a China Mobile fund and other private investors.
This capital provision indicates that investors are providing capital where a credible roadmap to chips, software compatibility, and sales outside the parent company is discernible.

The Kunlunxin chip, the core of Baidu's AI strategy, is the focus of the planned IPO in Hong Kong.
Technology and Market Position
Kunlunxin was established in 2012 as an internal unit. to develop AI chips for Baidu. A strategic focus is on external sales: Kunlunxin expected in 2025 more than half of its revenue outside of Baidu.
Baidu put into operation a cluster infrastructure in 2025 with 30,000 self-developed P800 Kunlun chips. An important aspect is compatibility: Kunlunxin supplies chips that are intended to be compatible with NVIDIA's CUDA platform. NVIDIA describes CUDA as a software layer that enables applications and frameworks to use GPUs, including a toolkit, libraries, and developer tools. (NVIDIA CUDA).
In August 2025, Reuters reported that Kunlunxin secured orders worth over 1 billion yuan for China Mobile AI projects.
Geopolitical Context
The geopolitical framework is accelerating developments. The US agency BIS describes export controls aimed at restricting China's access to advanced computing chips and manufacturing equipment. In parallel, pressure is growing in China for self-sufficiency along the supply chain. Reuters reported at the end of 2025 that authorities are effectively obliging chipmakers to use at least 50% domestic equipment (according to sources).
In this environment, an IPO path is not just for financing but also for signaling: those who open up to the capital market want to bind capacity, customers, and partners faster, while at the same time showing that “domestic alternatives” are more than a slogan.

Baidu Kunlunxin's planned IPO in Hong Kong is intended to provide the company with fresh capital for the further development of its AI chip technology.
Outlook and Open Questions
The speed at which the confidential filing becomes a prospectus depends on the process in Hong Kong. The HKEX explains key terms related to listing applications (Form A1), hearings, and publications on HKEXnews.
Investors will focus on three points:
- Whether Kunlunxin plausibly falls under Hong Kong's Specialist Technology Regime (Main Board Chapter 18C).
- Whether the "CUDA compatibility" saves costs in practice when developers migrate from NVIDIA GPUs.
- How stable the story "outside of Baidu" is, as this impacts scaling, margins, and valuation levels.
The "Baidu Kunlunxin IPO Hong Kong Application" is more than routine. Baidu is linking its chip subsidiary to the capital market without giving up control, positioning Kunlunxin where China is currently most focused: on compute capacity, software ecosystems, and supply chain sovereignty.
Whether this will result in a major IPO depends on the execution: genuine external revenue, convincing platform compatibility, and a pace that can keep up with NVIDIA's ecosystem pressure.
