Baidu's Kunlun Core M100: Another Positive Step in AI Chip Development
Baidu's Kunlun Core M100 is another encouraging development in China's domestic AI chip industry. Officially unveiled at the Baidu World Conference on November 13, 2025, the chip was designed primarily for large-scale AI inference, particularly Mixture of Experts (MoE) models.
Unlike chips focused primarily on model training, the M100 targets the increasingly important inference market, where efficiency, energy consumption, and operating costs are becoming major competitive factors. It uses Kunlunxin's self-developed XPU architecture, aiming to deliver better inference performance and cost efficiency. The progress has also been encouraging. By June 2026, M100 chips had already reached major customers for testing, with initial shipments underway. In July, the physical product made its first public appearance in a CCTV report, and by November 2026, it had officially reached the market.
But Baidu's ambitions go beyond a single chip. The M100 is part of a broader AI infrastructure strategy, working alongside the Tianchi Supernode platform. Baidu is also developing the M300, expected in 2027, which will target the demanding training and inference requirements of extremely large multimodal models.
Another particularly interesting aspect is Kunlunxin's commercial expansion. Its external customer business has grown significantly, with sales to third parties reportedly exceeding internal supply to Baidu itself. The company is also pursuing independent listing plans, potentially unlocking additional investment and visibility for its semiconductor business.
Overall, I see the M100 as a positive milestone. Building competitive AI hardware is not something that happens overnight, and having a consistent product roadmap, growing customer adoption, and an expanding infrastructure ecosystem is certainly encouraging. Baidu appears to be taking a long-term approach rather than simply chasing headlines, and that is perhaps the most interesting part of this development.
Kunlunxin is seeking listings in Hong Kong stocks and A-shares. It submitted a listing application to the Hong Kong Stock Exchange in January 2026 and commenced pre-IPO tutoring for a The Science and Technology Innovation Board IPO in early May. Baidu expects to facilitate Kunlunxin's listing in Hong Kong stocks within 2026, with valuation is estimated at US$44 billion, and more positive assessments place the IPO above 50B, with some forecasts even reaching close to 60B.
