OpenAI, Anthropic and SpaceX Valuations Could Dwarf 45 Years of IPOs
Synopsis
OpenAI, Anthropic and SpaceX could together represent more than $5 trillion in value, highlighting the extraordinary scale of AI company valuations in 2026 compared with decades of US technology IPOs.
The scale of the AI boom is becoming clearer as some of the technology sector’s biggest private and newly public companies reach valuations measured in trillions of dollars.
OpenAI, Anthropic and SpaceX together could be valued at more than $5 trillion, a figure that exceeds the combined value of US technology companies at IPO from 1980 through 2025, according to data cited by the Financial Times.
AI Company Valuations Reach Historic Scale
OpenAI is in early discussions with investors about a funding round that could value the company at around $1.2 trillion, according to reports citing the Financial Times. The discussions remain preliminary, and the valuation could change. OpenAI has also indicated that it does not plan to go public in 2026.
Anthropic, meanwhile, is being linked to a potential $2 trillion IPO valuation. Its expected listing would put it among the largest public offerings ever if that valuation is achieved. SpaceX has already entered public markets at a valuation around $2 trillion, adding another major company to the comparison.
OpenAI Anthropic SpaceX Valuations Put IPO History in Perspective
The three companies’ combined prospective and current valuations come to more than $5 trillion. By comparison, 3,365 technology companies that went public in the US between 1980 and 2025 had a combined value of about $4.1 trillion when they began trading, based on data from University of Florida professor Jay Ritter. The historical figure is not adjusted for inflation.
The comparison highlights how much capital is now flowing into a small group of AI and technology companies before they reach public markets. Nvidia, which supplies chips used across AI infrastructure, has also reached a multitrillion-dollar valuation, underscoring the wider scale of the sector.
AI IPOs Face Questions Alongside Huge Valuations
The rapid rise in trillion dollar AI startups has also brought questions about the sustainability of current valuations and the enormous capital required to develop advanced models. OpenAI, for example, is expected to require substantial investment in computing infrastructure as it expands.
For investors watching US tech IPO history, the next major listings will show whether these extraordinary private-market valuations can translate into equally large public companies.
