一 | (ECNS) -- Chinese humanoid robot maker Unitree Robotics has attracted strong market attention after its IPO subscription results showed the lowest winning rate in the history of Shanghai’s STAR Market. Unitree priced its shares at 150.80 yuan ($22.2) each, requiring successful applicants to pay 75,400 yuan for one lot of 500 shares. The online winning rate was just 0.0181 percent, prompting comparisons to “winning a lottery.” Unitree Robotics issued about 40.45 million shares, accounting for 10 percent of its post-IPO total shares, and is expected to raise about 6.1 billion yuan. Based on the issue price, the company’s market capitalization is estimated at about 61 billion yuan. The IPO attracted a strong lineup of strategic investors, led by the National Council for Social Security Fund. Major technology and industrial investors also participated, including DeepSeek, Kunlun Capital under China National Petroleum Corporation, China Southern Power Grid and China Telecom Capital. DeepSeek received about 933,000 shares worth 141 million yuan, subject to a 36-month lock-up. Meituan-affiliated investment entities are among the company’s largest external shareholders, while Tencent, Alibaba and Ant Group also hold stakes in the company. Leading venture capital firms Sequoia China and Matrix Partners China, along with state-backed investors such as the Beijing Robotics Industry Development Investment Fund and Shenzhen Capital Group, further broadened support. Founder Wang Xingxing is also expected to benefit from the listing. Before the IPO, Wang held about 33.36% of the company’s shares directly and indirectly. Based on the issue price, his stake was valued at around 18.3 billion yuan, though his ownership ratio will be diluted after the listing. The IPO also lifted related robotics stocks on Aug. 11 and 12.
