As the artificial intelligence sector continues to expand, Anthropic is positioning itself as a formidable contender against SpaceX for the title of the largest initial public offering (IPO) in 2026. Although Anthropic has yet to enter the public market, investor anticipation suggests that the company might take this step by the fourth quarter of that year. With its annualized revenue projected to climb to approximately $65 billion—a notable boost from previous predictions—Anthropic’s valuation in private markets has soared to around $1 trillion, making it one of the most valuable privately-held tech firms globally. This rapid growth fuels speculation that the company could achieve an even greater valuation with an IPO.
SpaceX, meanwhile, has already made its mark in the 2026 IPO landscape with a significant public offering priced at $135 per share, reaching an initial valuation near $1.78 trillion. The company’s shares experienced a strong surge following the market debut, briefly elevating SpaceX’s valuation beyond $2 trillion before encountering volatility. As its stock adjusted, reflecting ongoing investor concerns about its high valuation and future expenditures, SpaceX maintained its lead over Anthropic in terms of market value. However, Anthropic’s impressive revenue growth might narrow this gap, especially if it secures a notably higher valuation when it goes public.
The burgeoning interest in artificial intelligence could play a pivotal role in bolstering Anthropic’s prospects. The sector has attracted significant private investment, leading to heightened expectations for the valuations of top AI companies. While OpenAI is also eyed as a possible IPO candidate, it does not currently pose as strong a challenge to SpaceX’s IPO supremacy for the year. The crucial element for Anthropic will be the valuation it achieves at the time of its offering announcement. With its current private valuation at about half of SpaceX’s market value, Anthropic would need to see a substantial increase to overtake SpaceX.
If Anthropic’s revenue trajectory continues on its upward path and investors value the company significantly higher at its IPO, it could potentially outpace SpaceX, claiming the title of the largest IPO of 2026. SpaceX remains the frontrunner for now, but the momentum Anthropic is gaining makes it one of the most watched IPO prospects of the year.
