AI Trio Hits $5.2T, Beating 45 Years of US Tech IPOs
OpenAI, Anthropic, and SpaceX combined value exceeds $5.2 trillion, surpassing total first-day value of 3,365 US tech IPOs since 1980.
Key points
- OpenAI, Anthropic, and SpaceX hold a combined $5.2 trillion valuation, surpassing $4.1 trillion from 3,365 US tech IPOs since 1980.
- SpaceX raised $75 billion in its IPO, closing at $160.95 initially before falling to $151.85, a 33% drop from its peak.
- OpenAI delays its IPO past 2026, while Anthropic considers a November listing at a $2 trillion valuation.
OpenAI, Anthropic, and SpaceX have reached a combined valuation of approximately $5.2 trillion. This figure exceeds the $4.1 trillion generated by the first-day trading value of 3,365 U.S. technology IPOs between 1980 and 2025. The data, highlighted by TradingView, indicates that investor capital is concentrating heavily in these three infrastructure platforms rather than spreading across the broader public market.
The valuation breakdown shows a significant concentration of value in private entities. OpenAI is estimated at $1.2 trillion, while Anthropic is valued at roughly $2 trillion. Together, these two companies represent about $3.2 trillion, or 62% of the total, despite neither having completed a public listing. SpaceX accounts for the remaining $2 trillion, providing a public market reference point for the private valuations.
SpaceX IPO Sets Market Benchmark
SpaceX priced its June IPO at $135 per share, establishing an initial valuation of $1.75 trillion. The shares opened at $150 and closed the first session at $160.95, pushing the market capitalization to approximately $2.1 trillion after raising $75 billion. This public transaction offers a direct comparison for the private valuations of OpenAI and Anthropic.
However, the stock has since experienced significant volatility. SpaceX reached an intraday high of $225.64 before retreating sharply to close at $151.85 on Monday. This level is 5.7% below the first-day close and nearly 33% below the record high. The price movement demonstrates that private valuation levels do not guarantee sustained public-market gains.
Private AI Companies Delay Listings
OpenAI has pushed back its IPO timetable and is not expected to list in 2026. Anthropic is reportedly considering a November offering at a valuation as high as $2 trillion, although timing and terms remain subject to change. Investors are watching whether these companies can convert rapid revenue growth into durable margins before entering public markets.
Valuation Risk Concentrated In Few
The comparison highlights that future AI growth expectations are already embedded in current technology valuations. The stakes are high for these companies to justify their market positions. Any changes in revenue growth or listing plans could quickly reset how investors value the broader AI sector.
