US export rules gatekeep yet another AI party, leaving China locked out.

Major investment banks, including Goldman Sachs and Morgan Stanley, are reportedly blocking investors from mainland China and Hong Kong from participating in Anthropic's upcoming initial public offering (IPO). The banks are citing US export control regulations, specifically the International Traffic in Arms Regulations (ITAR), which govern defense-related technologies, as the justification for excluding these investors.

This move deepens the ongoing geopolitical tech blockade, turning a financial event into a regulatory checkpoint. For the global AI industry, it reinforces that capital flow is now a strategic tool, not just an economic one. The IPO itself proceeds, but the investor pool is being carefully filtered along geopolitical lines, highlighting how national security concerns are reshaping even public market access. The takeaway: in the AI race, your wallet's nationality matters as much as its size.
