SpaceX filed for an IPO that could value the company at roughly $1.5 trillion, aiming for a mid‑next‑month listing. The filing arrives just two days after Elon Musk lost a jury trial challenging OpenAI’s corporate structure, a defeat that exposed internal details about Sam Altman’s leadership. Investors will compare two very different AI playbooks.

OpenAI is expected to file its own prospectus within days, targeting a valuation near its last private‑market price of $852 billion. Though the chatbot maker posted $13.1 billion in 2025 revenue, rivals such as Google’s DeepMind and Anthropic are chipping away at ChatGPT’s first‑mover edge, raising questions about sustainable growth.

SpaceX’s moat rests on its integrated launch service and satellite internet business, which generated $18.7 billion in 2025 revenue. Those figures place both firms in the middle of the S&P 500, yet the eleven companies with market caps above $1 trillion average just $260 billion in annual sales, highlighting a valuation stretch for both.

Investors must weigh SpaceX’s tangible cash flow against OpenAI’s reliance on licensing deals and rapid model turnover. The juxtaposition of a rocket empire and a cloud‑based AI service underscores how divergent paths can command similar headline numbers, forcing the market to decide which growth story justifies a trillion‑dollar tag.
