Anthropic, the artificial intelligence company behind the Claude family of AI models, has confidentially filed a draft S-1 registration statement with the US Securities and Exchange Commission on June 1, 2026, signaling its intention to go public in what could become the largest initial public offering in history. The filing comes on the heels of a fresh $65 billion Series H funding round that lifted the company's private valuation to approximately $965 billion, making it one of the most valuable private companies ever to pursue a public listing.
The San Francisco-based company is reportedly aiming for a valuation between $1.75 trillion and $1.8 trillion at the time of its IPO, with plans to raise up to $75 billion in the offering. If successful, the deal would surpass Saudi Aramco's 2019 IPO as the largest in history, underscoring the extraordinary investor appetite for artificial intelligence companies. The number of shares to be offered and the expected price range have not yet been determined, according to sources familiar with the matter.
Anthropic's financial trajectory has been nothing short of remarkable. The company's revenue run-rate reached approximately $47 billion in May 2026, representing a roughly fivefold increase from the approximately $10 billion run-rate recorded the prior year. This explosive growth has been driven by surging demand for its Claude AI models across enterprise, consumer, and developer markets, as businesses worldwide accelerate their adoption of generative artificial intelligence tools.
The confidential filing process allows the SEC to review the registration statement before it becomes publicly available, giving the company flexibility to address regulatory feedback without the pressure of public scrutiny. This approach has become increasingly common among high-profile technology companies seeking to go public, as it allows management to refine their disclosure documents and timing strategy while maintaining control over the narrative around their public market debut.
No listing venue or specific timeline for the offering has been disclosed, and the company has emphasized that the IPO remains subject to market conditions and regulatory approval. Industry analysts note that the current market environment has been generally favorable for technology IPOs, though geopolitical tensions and macroeconomic uncertainty could influence the timing and pricing of the deal. The company's backers include major technology firms and venture capital investors who stand to realize substantial returns on their early investments.
Anthropic's move toward a public listing places it at the forefront of a broader wave of AI companies seeking access to public capital markets. The company, founded in 2021 by former members of OpenAI, has distinguished itself through its focus on AI safety research alongside commercial product development. Its planned IPO represents a watershed moment for the artificial intelligence industry, which has attracted hundreds of billions of dollars in private investment over the past several years and now appears poised to tap public markets at unprecedented scale.
