Anthropic PBC has delayed its planned initial public offering to November, pushing back from an earlier October target. The company is weighing whether to release a new frontier AI model before the offering while citing a rapidly rising revenue run rate that has increased valuation expectations ahead of the IPO.

IPO Timing and Model Decision

Anthropic is targeting a November IPO, later than the previously anticipated October debut. The company could push the offering to after the November U.S. midterm elections, though those elections are not expected to have a material effect on timing.

The company is considering launching a new frontier AI model ahead of the IPO to counter competitive momentum from OpenAI’s GPT-6 Astra. Internal safety evaluations are a key factor in deciding whether to proceed with the release. This deliberation follows CEO Dario Amodei’s public calls for slowing the development of more capable AI systems, highlighting tension between safety concerns and the pace of product and financing milestones.

Revenue Surge and Financial Context

Anthropic’s annualized revenue run rate reached about $65 billion by the end of July 2026, up from roughly $9 billion at the end of 2025. The company is expected to generate more than $100 billion in annualized revenue this year, though reported 2026 revenue is estimated closer to $20–26 billion. Projections indicate revenue could reach roughly $190–200 billion by 2028.

In a related move, Anthropic and Accenture each committed at least $1 billion over five years to build capacity for independent evaluation of Anthropic’s frontier AI models, creating $2 billion in resources for model evaluation and safety work. This partnership reflects growing focus on safety and governance as the company weighs new product releases.

Anthropic has also told shareholders it expects positive adjusted operating income for a second consecutive quarter, signaling near-term adjusted profitability.

Together, the company’s rapid revenue growth, model-release deliberations, and safety investments are shaping its investor narrative and underpin elevated valuation expectations ahead of the IPO.
