China robot maker Unitree’s post-listing slump sparks bubble fears

A roughly 45% slump in the shares of Unitree, China’s best-known humanoid robot maker, since a more than fivefold jump on its Shanghai debut has triggered concerns about bubble ​risk, retail investor losses and flaws in the IPO system.

The wild ​swings in Unitree’s valuation – soaring to $66 billion at one point and later plunging by $30 billion – have led to questions about whether enthusiasm for ​AI and robotics has outpaced fundamentals.

The post-listing selloff in the company, one of the world’s largest producers of quadruped and humanoid robots, has also led to soul-searching over China’s listing mechanism, which some analysts say distorts prices.
