When SpaceX starts trading this week, one group will be noticeably absent from the frenzy: investors from China and Hong Kong. They are also likely to miss out on the upcoming initial public offering for OpenAI.
SpaceX, Elon Musk’s rocket maker and artificial intelligence company, has excluded investors in China and Hong Kong from participating in its I.P.O., according to five people with knowledge of the decision, who asked not to be identified because they were not authorized to speak publicly.
OpenAI, another leading A.I. company, is likely to impose the same restriction when it goes public this year, said three people with knowledge of the discussion. The company has already barred Chinese investors from participating in private fund-raising rounds, one of those people said.
The A.I. companies have not disclosed why they are hesitant to accept investments from the region, and it’s unclear whether the move is being made with input from the Trump administration. But Washington has been focused on keeping artificial intelligence out of China’s reach. Both companies count the U.S. government as major clients.
While Chinese investors have largely been shut out of private investments in sensitive sectors for years, this is most likely the first time investors in mainland China and Hong Kong have been excluded from a major American I.P.O., bankers in the region say.
It highlights how the United States and China have steadily scaled back trade, investment and collaboration — especially in sensitive sectors involving technology and science.
