Anthropic, a rapidly growing artificial intelligence company, is positioning itself as a formidable contender in the race for the largest initial public offering (IPO) of 2026, potentially rivaling SpaceX. While Anthropic has not yet made its public debut, the company’s rising revenue and valuation have sparked investor speculation about a possible IPO as early as the fourth quarter of 2026. With its annualized revenue potentially reaching around $65 billion, the company is currently valued at approximately $1 trillion in private markets, ranking it among the world’s most valuable privately held tech firms.
SpaceX, known for its significant market presence, currently leads in the 2026 IPO race after its own substantial public offering. Initially priced at $135 per share, SpaceX’s IPO resulted in a valuation of about $1.78 trillion. The stock saw a strong performance post-market debut, with its valuation peaking above $2 trillion, although it later faced notable volatility. Despite fluctuations, SpaceX maintains its edge over Anthropic in terms of market value. However, Anthropic’s swift revenue growth could potentially close this gap if the company achieves a higher valuation during its IPO.
The ongoing boom in artificial intelligence could further bolster Anthropic’s appeal to investors. The surge in demand for advanced AI systems has led to significant private investment in this sector, elevating expectations for the valuations of leading AI companies. Although OpenAI is also seen as a potential IPO candidate, it currently does not pose as strong a challenge to SpaceX as Anthropic does in terms of the largest IPO of the year.
For Anthropic, the critical determinant will be its valuation at the time of its IPO announcement. Currently, the company’s private valuation stands at about half of SpaceX’s market value, indicating that a substantial increase is necessary to surpass the space company. Should Anthropic’s revenue continue its upward trajectory and attract a considerably higher valuation at IPO, it might overtake SpaceX and claim the title of the biggest IPO of 2026.
As it stands, SpaceX remains in the lead, but Anthropic is rapidly emerging as one of the most closely watched potential IPO candidates for 2026. The evolving dynamics between these two industry giants underline the competitive nature of the IPO landscape, with investor attention increasingly focused on the burgeoning AI sector.
