Unitree Robotics opened at a 629 percent premium to its 150.80 yuan IPO price, handing the humanoid robot maker a $66 billion valuation on its Shanghai debut, a listing that drew nearly 9.8 million retail accounts for fewer than 10 million shares in the online tranche.

The allocation math

The subscription frenzy produced an allocation rate of 0.018 percent, meaning roughly one in 5,500 applicants received a single share. That imbalance reflects a structural quirk: mainland IPOs reserve a fixed slice for retail investors regardless of demand, so the more accounts that pile in, the thinner the slice becomes.

The pullback

The opening pop was followed by a sharp reversal, with the stock dropping below 900 yuan in early morning trading. From a peak near 1,100 yuan, the 629 percent print, that marks a decline of roughly 18 percent before the lunch break, a reminder that the valuation multiple compresses as quickly as it expands when the float is this thin.

The conference backdrop

The debut coincides with the World Robot Conference in Beijing, which runs through Sunday and features product launches, industry forums and robot contests. Unitree’s timing was deliberate: the first humanoid robot maker to list on a mainland exchange arrived just as the sector’s largest domestic gathering opened its doors.

What to watch next

The lock-up expiration schedule and any follow-on convertible supply will determine whether the 0.018 percent allocation rate was a one-off spectacle or a sustainable pricing signal. For now, the market has priced a pre-revenue hardware company at a multiple that assumes flawless execution in a category where mass production has yet to begin.
