SpaceX, OpenAI and Anthropic Race to IPOs

SpaceX, OpenAI and Anthropic are all moving toward public listings, creating a clustered wave of blockbuster IPO activity. According to The Guardian, SpaceX disclosed plans that point to a Nasdaq listing and a valuation near $1.75 trillion, and The Hill reports the company filed a preliminary prospectus showing $18.67 billion in revenue for 2025 and a $4.28 billion loss in the first three months of 2026. The New York Times and other outlets report that OpenAI is preparing a confidential filing, while media coverage describes Anthropic as taking steps to test public-market demand.

The public reporting highlights capital intensity rather than model architecture or product roadmaps. The Hill and The Guardian note heavy capital expenditure at SpaceX, including funds channeled into the AI arm xAI and broader infrastructure; those filings and disclosures are the primary technical-financial documents available to markets. The Financial Times and Wall Street Journal coverage emphasize investor appetite for companies that can scale compute, data centres and specialized infrastructure at very large scale.

Reporting from CNBC, WSJ and The Week highlights a mix of enthusiasm and caution. The Week quotes Rob Hilmer calling the AI giants "well run, high-growth businesses," per the Financial Times, while other analysts cited by CNBC warn that public investors will scrutinise ongoing cash burn. The Guardian also reports on the recent legal outcome between Elon Musk and OpenAI founders, noting a jury verdict that cleared OpenAI in a dispute brought by Musk; some coverage links that outcome to OpenAI's clearer path to a public listing.

Companies seeking IPO financing at this scale typically aim to monetise earlier private valuations and secure capital for long-tail infrastructure projects, including data centres, GPUs and networking. Observers quoted in The Hill and The Week frame the public listings as a response to the enormous cash requirements of frontier AI, not merely a liquidity event for early investors.

Observers should follow three indicators: prospectus detail on capital allocation and AI-related capex, disclosed unit economics for AI services and the allotment and pricing mechanics in each float. Public filings from SpaceX and any confidential filing details that emerge from OpenAI or Anthropic will be the decisive sources for valuation, revenue breakdowns and loss trajectories.

For ML engineers and infrastructure teams, large IPOs at these valuations imply continued investment in bespoke compute, custom accelerators and expanded data-centre footprints industry wide. Industry funding flows also affect vendor pricing, open-source participation and talent competition, as described in reporting by the Financial Times and The New York Times.

All statements about internal intentions or future actions by the companies are drawn from published filings and external reporting. Where no direct company statement exists in the cited coverage, those companies "have not issued a public statement on the rationale" is the accurate condition.
