On March 20, the Shanghai Stock Exchange accepted the IPO application of Unitree Robotics Co., Ltd. for the STAR Market, with Unitree Robotics potentially becoming the "first A-share humanoid robot stock." China Securities Journal reporters found that over 20 insurance companies have indirectly invested in Unitree Robotics as limited partners (LPs) by participating in private equity funds. Specifically, China Post Life and AIA Life are secondary shareholders with relatively high shareholding ratios. In addition to investing in Unitree Robotics, insurance funds have also used these equity funds to invest in numerous unlisted hard technology companies, involving industries such as semiconductor equipment, chip design, humanoid robots, and biotechnology.
