Anthropic told prospective investors at a San Francisco meeting on October 14, 2026, that its third-quarter revenue surged and that it was profitable on an adjusted basis. The presentation aimed to set the stage for a potential November IPO.
Q3 Revenue and Profit Claims
Anthropic reported third-quarter revenue of $16.8 billion, a 45% increase from the prior quarter, according to an investor who attended the private meeting. The company also presented revenue progression for 2026, showing $4.7 billion in the first quarter and $11.6 billion in the second.
The company said it was profitable on an adjusted basis in the third quarter, though the presentation did not disclose the nature of the adjustments or provide a reconciliation to generally accepted accounting principles (GAAP). The materials also showed that revenue rose to nearly $4.6 billion in 2025, while operating losses exceeded $8 billion, excluding certain liability-related writedowns.
These Q3 figures and the profit claim have not been confirmed in any public company filing or release.
IPO Timing and Accounting
Anthropic held the investor meeting at its San Francisco headquarters to brief prospective institutional investors ahead of a possible IPO. The company reportedly submitted a confidential filing with the Securities and Exchange Commission earlier in 2026 but has not publicly released an S-1 prospectus. No SEC effectiveness notice or exchange listing approval has been identified.
Formal IPO marketing could begin the week of November 9, 2026, with a listing in November presented as a possibility rather than a confirmed date. Reports have cited potential proceeds above $100 billion and a valuation near $2 trillion, but these figures have not been verified in any public filing.
It remains unclear whether the revenue figures include partner-related sales or use the same accounting treatment as prior reported numbers. The ticker "P-ANTH" has not been supported by any exchange notice or public listing document.
The presentation linked the company’s growth to continued demand for Claude and other AI services, while outside accounts highlighted substantial computing and infrastructure costs. No quantified guidance for capital spending, gross margin, cash flow, or full-year profitability was disclosed.
