China's humanoid robotics sector faces regulatory scrutiny and IPO volatility

China’s humanoid robotics sector is facing a period of intense scrutiny and market volatility. While the industry has expanded from a few dozen startups to over 150 companies, recent performance has raised concerns about a potential bubble. Unitree, a leading startup in the field, saw its shares plunge more than 50 percent from their peak following its Shanghai IPO.

Regulators have reportedly implemented informal “window guidance” to slow the review process for humanoid robotics initial public offerings (IPOs). This shift is driven by concerns over inflated valuations and the quality of corporate revenues. Specifically, there are questions regarding whether revenue linked to local government projects represents genuine commercial demand, as excluding certain data-collection center revenues could significantly reduce firm valuations.

Despite these challenges, the sector remains highly active. More than 50 companies are expected to pursue public listings in China and Hong Kong by the end of 2026. In Hong Kong, robotics and embodied AI firms represent a highly congested segment under the Chapter 18C specialist technology regime. While some view the current regulatory environment as an implicit freeze, others see it as a tactical moderation to ensure long-term sustainability.
