An unofficial market has emerged around Yushu Technology's IPO before the company has formally listed, with posts on Xianyu and other second-hand platforms offering to buy or sell rights tied to winning allotments. One listing sought 500,000 yuan for a winning allocation and described Yushu Technology as the STAR Market's first humanoid-robotics leader, while a screenshot showed an investor subscribed for 6,000 shares and won 500 shares, implying 75,400 yuan of subscription funds at the 150.8 yuan issue price. Intermediaries were also said to be sourcing the stock through various channels, with quoted prices diverging sharply, including 520 yuan a share, about 3.45 times the issue price, and 410 yuan, about 2.72 times. Yushu Technology's online initial offering totaled just 6.471 million shares, which at 500 shares per lot implies only about 12,900 winning numbers across the market. Several brokerage and mutual fund professionals said they had not previously encountered any so-called "dark market" in STAR Market IPO subscriptions. In China's A-share market, private purchases of new-share rights are informal verbal agreements that lack legal protection and carry substantial compliance and settlement risks.
