Anthropic is positioning itself as a formidable contender against SpaceX in the race for the largest initial public offering (IPO) of 2026. With its revenue and valuation on a sharp upward trajectory, the artificial intelligence firm is garnering significant attention. While Anthropic remains privately held, investor anticipation is mounting, suggesting a possible public debut by the fourth quarter of 2026. Current reports indicate the company’s annualized revenue could hit approximately $65 billion, marking a dramatic leap from prior assessments.
In the private market, Anthropic’s valuation hovers around $1 trillion, placing it among the elite ranks of the world’s most valuable privately-owned tech enterprises. This rapid development has fueled speculation that the company might secure an even loftier valuation upon going public. Meanwhile, SpaceX has set a high bar in the IPO landscape following its own substantial public offering. SpaceX’s IPO was initially priced at $135 per share, bestowing it with a valuation near $1.78 trillion. Post-launch, SpaceX’s shares experienced a significant surge, pushing its valuation past $2 trillion, though investor uncertainty later led to notable stock volatility.
Despite SpaceX’s current lead in market value, Anthropic’s swift revenue growth could potentially close the gap, especially if it achieves a higher valuation at its IPO. The burgeoning enthusiasm for artificial intelligence could play in Anthropic’s favor. The sector’s allure has attracted vast private investments, raising the stakes for leading AI companies’ valuations. While OpenAI remains another IPO candidate, it’s not presently seen as the top competitor to SpaceX for the largest IPO title of 2026.
The pivotal element for Anthropic will be the valuation it commands when it eventually announces its IPO. With its private valuation standing at about half of SpaceX’s market value, Anthropic would require a significant boost to overtake the space exploration giant. Should Anthropic’s revenue maintain its rapid growth and investors bestow it with a considerably higher valuation at the time of its public offering, the company could surpass SpaceX, claiming the title of the biggest IPO of 2026.
For now, SpaceX holds the leading position, but Anthropic’s fast-paced expansion makes it one of the most closely monitored IPO prospects of the year. The coming years will determine whether Anthropic can translate its private market success into a record-breaking public debut.
