Chinese embodied-AI startup X Square Robot has vaulted past a US$2.8 billion valuation after closing four consecutive financing rounds capped by a Series C, the company announced on June 29, 2026, cementing its place among China's most valuable physical-AI companies.
Four rounds, four tech giants
The latest Series C drew participation from IDG Capital, while earlier rounds were led at different stages by HongShan, Xiaomi, Meituan, Alibaba and ByteDance. X Square says it is the only embodied-AI company in China to have secured lead-round backing from four of the country's leading technology firms - a striking show of strategic conviction in a crowded humanoid market.
A unified model for the physical world
Founded in Beijing in December 2023, X Square Robot builds general-purpose robots aimed at the home, with the goal of handling everyday tasks like tidying and cooking. In April 2026 it introduced WALL-B, an embodied foundation model built on a World Unified Model architecture. Unlike modular vision-language-action systems that connect separate perception, language and action components, WALL-B trains all of them - plus physical prediction - inside a single network, which the company says yields stronger spatial reasoning and continual learning from real-world interaction.
Funding the data flywheel
X Square plans to use the capital to deepen foundational research in embodied intelligence, expand its model-driven automated data pipeline, and accelerate commercial robot deployments. The raise extends a remarkable run for the company, which earlier this year completed a $276 million Series B. It joins a swelling field of richly funded Chinese embodied-AI players such as RoboEra and Spirit AI, as global robotics funding races to record highs in 2026.
