Summary

Anthropic, the AI startup, filed a confidential S-1 form with the US Securities and Exchange Commission on June 1, 2026, initiating its path to an initial public offering. This move positions Anthropic ahead of rival OpenAI in the IPO race, following its recent Series H funding round that secured \$65 billion. This funding propelled Anthropic's post-money valuation to \$965 billion, surpassing OpenAI's last reported valuation of \$852 billion. The company's "Claude Code" is cited as a factor in its strong reputation and higher revenue, despite a smaller user base. However, concerns about the realism of its valuation and profitability persist, with the company reportedly on the verge of its first operating profit quarter. The public release of the IPO filing is anticipated to offer the first transparent look into Anthropic's financial health, potentially impacting perceptions of the broader AI market "bubble."

Key takeaway

For investors evaluating the AI sector, Anthropic's confidential S-1 filing marks a pivotal moment. You should closely monitor the eventual public release of its financial disclosures. These will provide the first verifiable data on profitability and expenses. This is crucial for assessing the realism of its \$965 billion valuation. Such transparency could validate market enthusiasm or expose vulnerabilities, influencing your investment decisions across the AI landscape.
