Anthropic Surprises Market by Filing for IPO Ahead of OpenAI, Eyes Trillion-Dollar Valuation

Bullish (0.8)Impact: High

Published on June 1, 2026 (3 hours ago) · By Vibe Trader

Anthropic, an artificial intelligence startup, announced on Monday that it has confidentially filed for an initial public offering (IPO), surprising the market by moving ahead of its main competitor, OpenAI, in the race to become the next trillion-dollar AI company to go public [1]. The filing is currently under review by the Securities and Exchange Commission, and details such as the number of shares to be offered and the pricing have not yet been determined [1].

Just days prior to the IPO filing, Anthropic revealed it had reached a valuation of $965 billion after raising $65 billion in new funding, reflecting the intense demand for its AI products [1]. If Anthropic debuts at a $1 trillion valuation, it would immediately join the ranks of the world's most valuable companies and could mark the second- or third-largest IPO in history, following SpaceX and Saudi Aramco [1].

Market analysts suggest that being the first to go public could give Anthropic a significant advantage in the competition for investor capital, as both Anthropic and OpenAI are expected to seek tens of billions of dollars in new funding in quick succession [1]. The broader AI sector, including suppliers and customers, is also seeking trillions of dollars in bond market funding to build out data centers for AI development [1]. Dan Ives, managing director at Wedbush, commented, "We believe this represents an opening of the floodgates for the IPO market, which has been relatively dormant for a few years" [1].

The timing of Anthropic's IPO is notable, as it is set to occur shortly after SpaceX's anticipated trillion-dollar IPO. Historical parallels are drawn to the 2019 IPOs of Uber and Lyft, where the company that went public first (Lyft) initially performed better in the market [1]. Anthropic's founders, several of whom are former OpenAI employees, stand to benefit personally from the IPO, with CEO Dario Amodei already reported to be worth $7 billion according to Forbes [1]. The company, founded five years ago, is structured as a public benefit corporation with a mission focused on the responsible development of advanced AI for the long-term benefit of humanity [1].

CONCLUSION

Anthropic's early IPO filing positions it ahead of OpenAI in the race for AI market dominance and could set a new benchmark for tech IPOs. The move is expected to have a significant impact on the IPO market and investor sentiment, with analysts predicting a surge in public offerings following Anthropic's lead. The outcome of this high-profile debut will be closely watched by both the tech and financial sectors.
