Three Major IPOs Set to Dominate 2026: SpaceX, OpenAI, and Anthropic Target Over $3 Trillion in Valuations

Three major private tech companies are gearing up to enter the public markets in 2026 through initial public offerings (IPOs) that could reshape global tech investment, with combined valuations surpassing $3 trillion.

SpaceX, led by Elon Musk, is preparing for an IPO in 2026 with a targeted valuation of $1.5 trillion, potentially surpassing Saudi Aramco’s record 2019 listing. The company aims to raise over $30 billion to fund ambitious projects, including space-based data centers and a lunar base. According to CFO Bret Johnsen, SpaceX was valued at $800 billion in its latest secondary share sale, double its July 2025 valuation. The company’s Starlink internet service, with 8.5 million users worldwide, is driving revenues close to $15 billion annually.

OpenAI, maker of ChatGPT, is considering a possible IPO in the second half of 2026, aiming for a valuation up to $1 trillion and a capital raise of at least $60 billion. Reports indicate that OpenAI is in preliminary talks with major law firms regarding the offering. The company’s annual revenue reached approximately $20 billion by the end of 2025, with projections of $200 billion by 2030. However, CFO Sarah Friar emphasized that an IPO is not a current priority, as the company focuses on developing artificial general intelligence (AGI).

Anthropic, the creator of the Claude AI chatbot and supported by Google and Amazon, has retained law firm Wilson Sonsini to prepare for a potential IPO in early 2026, targeting a valuation above $300 billion. Anthropic expects to double its annual revenue to $26 billion by 2026 and counts over 300,000 enterprise clients, with a focus on delivering safe AI solutions for regulated sectors such as healthcare, finance, and law. The company is also in discussions for a private funding round involving $15 billion in commitments from Microsoft and Nvidia.

These IPOs face major challenges, particularly high valuations amid concerns about an AI bubble. All three companies rely on substantial infrastructure investments without yet achieving sustainable profitability, raising questions about the viability of their business models. Analysts suggest that successful listings could reshape the U.S. tech market and the NASDAQ, but others warn of risks, citing past IPOs like Uber and Rivian that saw significant declines after going public.
