Anthropic is positioning itself as a formidable rival to SpaceX in the quest for the most significant initial public offering (IPO) of 2026. The artificial intelligence company’s financial growth is fueling speculation about a potential public debut as early as the fourth quarter of 2026. With annual revenues projected to reach approximately $65 billion, Anthropic’s financial performance has surpassed earlier expectations. In private markets, the company is valued at around $1 trillion, making it one of the world’s most valuable privately held tech firms. This rapid growth trajectory suggests that Anthropic could achieve an even higher valuation upon going public.
SpaceX, which has already made a considerable impact with its IPO, remains a dominant force in the 2026 IPO landscape. Its shares were initially priced at $135, setting its valuation at about $1.78 trillion. Following its market debut, SpaceX’s value surged past $2 trillion, though it later experienced fluctuations due to investor uncertainties regarding its valuation and future expenses. Although SpaceX currently leads in market value, Anthropic’s swift revenue increase might close the gap, especially if it secures a substantial valuation during its public offering.
The burgeoning interest in artificial intelligence could play in Anthropic’s favor, as investors continue to show enthusiasm for advanced AI technologies. This sector has attracted significant private investment, elevating expectations for leading AI companies’ valuations. While OpenAI is also in the conversation as a potential IPO candidate, it is not yet perceived as a strong competitor to SpaceX for the title of the year’s largest IPO.
The decisive factor for Anthropic will be the valuation it receives when it officially enters the public market. Its current valuation stands at around half of SpaceX’s market value, indicating that Anthropic would need a considerable boost in valuation to surpass the space exploration giant. If Anthropic’s revenue and valuation continue to climb, the company may well overtake SpaceX as the most significant IPO of 2026.
As it stands, SpaceX maintains its lead, but Anthropic’s rapid ascent keeps it in the spotlight as one of the most closely watched IPO candidates of the year. The outcome will largely depend on how the market values Anthropic’s growth and potential when it finally decides to go public.
