Baidu spins off AI chip unit Kunlunxin; files confidentially for Hong Kong IPO, $3B+ valuation

Baidu announced that its AI chip subsidiary Kunlunxin has confidentially filed for a Hong Kong IPO, positioning the unit as a standalone play on China's push for semiconductor self-reliance. The filing came in early January 2026, with Baidu retaining a controlling 59.45% stake post-spin-off. Kunlunxin has been valued at approximately $3 billion based on recent funding rounds. The timing coincides with a surge in Hong Kong tech IPOs, which raised $36.5 billion across 114 listings in 2025—Hong Kong's strongest year since 2021.

Founded in 2012 as Baidu's internal chip unit, Kunlunxin has evolved into an independently operated business and expanded external sales over the past two years beyond Baidu's own demand. The company serves 100+ enterprise clients and has secured major deals including a 1 billion yuan ($143 million) contract with China Mobile. Kunlunxin is developing M100 and M300 AI chips for inference and large-scale training, planned for launch in 2026 and 2027 respectively. The IPO aims to unlock the company's value, attract chip-focused investors, and provide direct access to capital markets for R&D and production scaling.

The separation reflects a broader Chinese tech trend: carving out capital-intensive hardware units to attract dedicated funding and strategic focus. JPMorgan analysts forecast Kunlunxin's chip sales could grow sixfold to 8 billion yuan in 2026. However, analysts note the company's chips are best suited for inference and government/telecom workloads where stable supply and lower cost matter more than peak performance, complementing rather than replacing NVIDIA entirely.
