Anthropic, a leading player in the artificial intelligence sector, is positioning itself as a formidable contender against SpaceX in the anticipated race for the largest initial public offering (IPO) in 2026. Despite not yet being publicly traded, the company’s surging revenue and burgeoning private-market valuation have fueled speculation of a potential IPO launch as soon as the fourth quarter of 2026. Reports indicate that Anthropic’s annualized revenue could reach approximately $65 billion, marking a substantial increase from previous projections.
Currently valued at around $1 trillion in private markets, Anthropic stands among the world’s most valuable privately held tech firms. This rapid growth trajectory has sparked discussions about the possibility of an even higher valuation should the company decide to go public. In the ongoing 2026 IPO race, SpaceX remains a dominant force following its massive public offering, which was initially priced at $135 per share, giving it a starting valuation of about $1.78 trillion. Despite experiencing volatility post-market debut, SpaceX’s valuation soared above $2 trillion, although it later faced fluctuations due to investor uncertainties regarding its valuation and future expenditures.
While SpaceX currently leads in market value, Anthropic’s swift revenue growth presents a potential challenge to narrow this gap, especially if the AI company secures a considerably higher valuation upon its IPO. As the demand for advanced artificial intelligence systems continues to attract significant private investment, Anthropic stands to benefit from the ongoing AI boom. This growing investor enthusiasm is likely to bolster the valuations of leading AI firms, positioning Anthropic as a significant player to watch.
OpenAI, another prominent name in the AI sector, is also seen as a potential IPO candidate, though it is not currently perceived as a strong challenger to SpaceX for the largest IPO title. For Anthropic, the decisive factor will be the valuation it receives when it officially announces its offering. With a current private valuation that’s about half of SpaceX’s market value, Anthropic would require a dramatic increase in valuation to surpass the space company.
Ultimately, if Anthropic’s revenue continues on its upward trajectory and investors assign it a higher valuation at the time of its IPO, the company could potentially outpace SpaceX, claiming the title of the biggest IPO of 2026. For now, SpaceX holds the lead, yet Anthropic’s progress has made it one of the most closely monitored potential IPO candidates for the year.
