X Square Robot said on June 29, 2026 that four consecutive financing rounds had lifted its valuation past $2.8 billion (about 20 billion yuan), capped by a Series C with IDG among the lead participants. Backers across the rounds include HongShan, Xiaomi, Meituan, Alibaba and ByteDance — an unusually deep bench of China's largest tech names.
Founded in 2023, X Square builds end-to-end embodied AI: a foundation model, the robots that run it, and the data pipeline that trains it. Its flagship WALL-B model uses what the company calls a 'World Unified Model' architecture; it reports its WALL-OSS-0.5 model completed four of seventeen real-robot tasks with over 80% autonomy without post-training. Those figures are company-reported.
The round is another vote for the full-stack thesis — that owning model, hardware and data together is how you win embodied AI — and another sign that China's platform giants are underwriting it directly. It lands the same week rivals like Ai2 Robotics raised at a similar mark, concentrating capital in a handful of well-funded Chinese platforms.
