The AI industry's privately funded era is ending. This week, two major players signaled their intention to go public, forcing public markets to finally price companies that have operated in venture capital's walled garden for nearly a decade.
SpaceX filed for the largest IPO in history on Wednesday, seeking $80 billion. The filing includes substantial AI operations and $6.4 billion in accumulated losses. The company's valuation reflects the market's confidence in Elon Musk's broader technology ambitions, though the losses highlight the capital intensity of AI development.
OpenAI plans to file within days, targeting a trillion-dollar valuation at debut in September. That valuation dwarfs SpaceX's ask and represents a stunning jump from OpenAI's last private funding round, which valued the company at $157 billion in October 2024.
The dual filings expose a fundamental tension. Venture capital and sovereign wealth funds have funded AI development based on future potential and narrative momentum. Public markets demand different accountability. They ask concrete questions about unit economics, path to profitability, and competitive moats. OpenAI's trillion-dollar target assumes the public will accept the same long-term faith that private investors have maintained.
These companies operate with massive burn rates and unclear profitability timelines. SpaceX's $6.4 billion in AI losses alone signal the scale of spending required to build frontier models and infrastructure. OpenAI's losses track similarly, despite generating revenue from ChatGPT and API access.
The public offerings will test whether institutional investors and retail shareholders embrace the AI investment thesis at the scale required. A trillion-dollar valuation for OpenAI requires belief that the company will generate returns proportional to that price. The market will demand concrete timelines for reaching profitability, not just promises about AGI.
These filings mark a turning point. For nine
