Major milestones

["2011: Project inception within Baidu's Intelligent Chip and Architecture Department.","2018: Launch of the first-generation Kunlun 1 AI chip.","2021-04: Independent spin-off from Baidu with a Series A valuation of 13 billion RMB.","2024: Secured a landmark 1 billion RMB contract with China Mobile.","2025-07: Completed Series D funding, raising 2.1 billion RMB at a 21 billion RMB valuation.","2026-01: Formally filed for a Hong Kong IPO."]

Growth metrics

Valued at approximately 21 billion RMB (~$3 billion) as of early 2026; 2025 annual revenue surpassed 2 billion RMB with forecasts predicting a 6x surge in revenue following its 2026 IPO filing.

Market positioning

A leading domestic challenger in China's high-performance AI chip market, positioned as a key alternative to global GPUs for cloud-to-edge computing, especially in large-scale model training (LLMs) and inference.

Geographic focus

Primarily focused on the Greater China market, driven by the national push for semiconductor self-reliance and the replacement of restricted foreign high-end AI silicon.

Patents and IP

Holds a leading position in Chinese AI chip patents (leveraging Baidu's top-ranked IP portfolio); core XPU architecture innovations have been published in top-tier global forums including Hot Chips and ISSCC.

About Ouyang Jian
