Below, we count down the top five publicly traded robotics stocks based on execution, revenue growth, margin trajectory, and strategic positioning in physical AI. Chinese humanoid robot maker Unitree just delivered one of the loudest signals yet that investor appetite for physical AI has reached full boil. Reuters reports Unitree's $900 million Shanghai IPO was more than 8,000 times oversubscribed by retail investors, with a lot-winning rate of roughly 0.018%. For context, SpaceX's much larger offering was approximately 4x oversubscribed ahead of its June debut, Snowflake's 2020 IPO was 120x, and Facebook's 2012 deal was 20x. Non-GAAP gross margin reached 75%, with Q2 revenue guided to $91 billion.
