Backing from Beijing and a frenzy of domestic investors have pushed Chinese tech valuations well beyond US peers, as the country’s AI sector positions itself as a serious challenger to Silicon Valley. The Star 50 index, tracking Shanghai’s most liquid tech firms, returned 29 % this year, outpacing the CSI 300’s 0.9 % and Hong Kong’s Hang Seng, which fell 1.5 %. Even after a recent sell‑off, the index’s price‑to‑earnings ratio sits above 150, compared with Nasdaq‑100’s 35.

The sky‑high multiples reflect confidence that China’s burgeoning AI industry can rival deep‑pitched US rivals. Gary Tan of Allspring Global Investments says investors are “making a bet on the Chinese ecosystem,” while the launch of Moonshot’s Kimi K3 and listing of CXMT—now China’s most valuable company—underscore rapid AI progress. Unitree Robotics’ IPO drew more than 5,500 times the available allotment for retail investors, illustrating the capital‑market frenzy.

Government support has also accelerated the boom. State‑backed funds have swooped in after a global chipmaker sell‑off, and Beijing’s push for semiconductor self‑sufficiency concentrates high valuations in chipmaking. Relaxed listing rules have pushed new tech firms onto Shanghai and Shenzhen exchanges, inflating the average price‑to‑earnings ratio to 268 and price‑to‑sales ratio to 43 this year.

Yet the surge occurs against a backdrop of economic fragility. The 2022 housing bust, the weakest consumer demand in decades, and a lack of meaningful stimulus leave Chinese equities highly volatile, even as Beijing hopes new industries will replace old ones and create high‑value jobs.
