Anthropic is positioning itself as a formidable contender against SpaceX in the pursuit of the largest initial public offering (IPO) anticipated in 2026. The artificial intelligence company’s escalating revenue and private-market valuation are fueling speculation about its potential public debut. Although Anthropic remains a privately held entity, investor expectations are mounting, hinting at the possibility of an IPO as early as the fourth quarter of 2026. Reports indicate that the company’s annualized revenue could reach approximately $65 billion, marking a substantial rise from previous projections.
With a private-market valuation nearing $1 trillion, Anthropic stands among the world’s most valuable private technology firms. This rapid growth trajectory has sparked discussions about the company’s potential to secure an even higher valuation upon going public. Currently, SpaceX holds a dominant position in the 2026 IPO race, following its remarkable public offering. SpaceX’s IPO was valued at $135 per share, leading to an initial valuation of around $1.78 trillion. Although its share value surged post-debut, reaching over $2 trillion, the stock has since experienced fluctuations, reflecting investor uncertainties regarding its valuation and future financial commitments.
While SpaceX maintains a lead over Anthropic in market value, the latter’s swift revenue growth could narrow the gap, particularly if it achieves a significantly elevated valuation during its IPO. The burgeoning enthusiasm for artificial intelligence could provide a substantial boost to Anthropic. The increasing demand for advanced AI systems has drawn considerable private investment, thereby enhancing expectations for the valuations of leading AI enterprises. Although OpenAI is also a potential IPO contender, it is not currently perceived as a major competitor to SpaceX for the title of largest IPO of the year.
The critical factor for Anthropic will be the valuation it commands when announcing an official offering. Presently, its private valuation is about half of SpaceX’s market value, indicating that a substantial valuation increase would be necessary to surpass the space giant. Should Anthropic’s revenue continue its rapid ascent and investors assign a much higher valuation at IPO, the company could potentially overtake SpaceX, seizing the distinction of the largest IPO of 2026. For now, SpaceX remains at the forefront, but Anthropic is rapidly gaining attention as one of the most closely monitored IPO prospects of the year.
