In the competitive race to secure the largest initial public offering (IPO) of 2026, Anthropic, a burgeoning player in the artificial intelligence sector, is positioning itself as a formidable competitor to SpaceX. Though not yet available on the public market, Anthropic’s escalating revenue and private valuation are fueling investor speculation that the company may go public by late 2026. Currently, the firm’s annualized revenue is projected to reach approximately $65 billion, a notable rise from previous forecasts. With a private-market valuation nearing $1 trillion, Anthropic stands among the most valuable privately held tech firms globally, sparking discussions about its potential to achieve an even greater valuation upon launching an IPO.
While Anthropic’s growth trajectory is impressive, SpaceX holds a commanding lead in the 2026 IPO race, having already completed a massive public offering. SpaceX’s shares debuted at $135, securing an initial valuation of around $1.78 trillion. The company experienced a strong stock performance post-IPO, with its market value surpassing $2 trillion before encountering significant volatility. Despite a sharp decline, the stock eventually recovered, reflecting enduring investor apprehension regarding its lofty valuation and future financial commitments. SpaceX’s current market value remains above Anthropic’s, yet the latter’s swift revenue growth could potentially close this gap if Anthropic secures a significantly enhanced valuation at its public debut.
The burgeoning enthusiasm for artificial intelligence could further bolster Anthropic’s prospects. The escalating demand for advanced AI technologies has drawn substantial private investment, elevating expectations for the valuations of leading companies in the sector. Although OpenAI is also seen as a potential IPO contender, it does not presently pose as strong a challenge to SpaceX’s IPO dominance as Anthropic does. The decisive factor for Anthropic will be the valuation it receives when it officially announces its offering. With its current private valuation at about half of SpaceX’s market value, Anthropic would require a significant valuation uplift to surpass the aerospace giant.
Anthropic’s future as a top IPO candidate hinges on its ability to sustain rapid revenue growth and secure investor confidence in its valuation at the time of its public launch. Should these conditions be met, Anthropic could potentially outshine SpaceX, claiming the title of the largest IPO of 2026. For now, SpaceX maintains its lead, but Anthropic’s swift ascent in the AI landscape makes it one of the most closely observed potential IPOs of the year.
