SpaceX and OpenAI IPOs Reject Chinese and Hong Kong Investors
Claire Weston
SpaceX has explicitly excluded mainland Chinese and Hong Kong investors from its IPO this week; OpenAI is likely to follow — marking the first time US-China tech capital decoupling has reached major US IPO subscriptions.
What exactly happened?
SpaceX launched its IPO this week with mainland Chinese and Hong Kong investors explicitly barred from participating.
Three people familiar with the matter say OpenAI will very likely impose the same restriction when it lists later this year; the company has already banned Chinese investors from its private funding rounds.
This means → the two highest-valued private tech companies in the world are shutting out Chinese capital from their IPOs almost simultaneously.
Why these two companies specifically?
SpaceX earned roughly $4 billion from the US government last year — its largest customer. OpenAI announced this year it will supply AI technology to classified Pentagon systems.
In plain terms = both companies are deeply embedded in the US national-security apparatus, making their capital sources far more politically sensitive than those of a typical tech firm.
Neither company has said whether the Trump administration directed the move. Former Biden White House tech-policy official Aaron Bartnick called it "voluntary."
Is this an industry-wide rule or a company-level choice?
Just last month, US chipmaker Cerebras completed a large IPO in which mainland Chinese and Hong Kong investors were still allowed to participate.
This means → the restriction is not a regulatory mandate — it is a deliberate choice by SpaceX and OpenAI, driven by their deep government ties.
US banking sources believe this is likely the first time Chinese and Hong Kong investors have been excluded from a major US IPO.
How are US-China investment barriers accelerating?
US side: the Biden administration restricted US investment in Chinese quantum computing, semiconductors, and AI; CFIUS continues to review cross-border M&A; the Pentagon's military-linked blacklist covers Tencent, Alibaba, Baidu, and BYD.
China side: last week Beijing tightened capital-outflow controls and announced plans to review strategically important companies seeking overseas expansion.
This reflects a shift — US-China tech-capital decoupling is expanding from government regulation into voluntary corporate action and public-market access.
What does this mean for the market?
Aaron Bartnick said other leading AI companies, including Anthropic, may adopt similar measures in future.
This means → SpaceX and OpenAI's decision could set a precedent for US tech IPOs — Chinese and Hong Kong capital's access to top-tier US tech listings is narrowing systematically.
Weeks earlier, the House Select Committee on China accused JPMorgan, Bank of America, and Morgan Stanley of insufficient due diligence when underwriting Chinese company listings — political pressure is now tightening from both the listing side and the investment side simultaneously.
