Anthropic targets mid-October IPO marketing at potential $2T valuation
Anthropic is approaching public markets with revenue and infrastructure commitments at a scale that will set expectations for how investors price frontier AI companies. Its unusual governance structure, which gives an external trust majority board control with no equity stake, will face its first test under public ownership.
Anthropic is targeting mid-October for IPO marketing while arranging a $15 billion revolving credit facility. The company's annualized revenue reached $65 billion in July 2026, up from $47 billion in May, following a private disclosure to investors. Anthropic posted its first profitable quarter in Q2 2026 with $11.5 billion in revenue, up 14x year over year, and told investors it expects Q3 to be profitable as well. The company has 6,000 customers spending $100,000 or more annually.
Bankers from Morgan Stanley, Goldman Sachs, and JPMorgan have told investors Anthropic could raise more than $100 billion in the IPO, implying a valuation near $2 trillion, which would more than double its $965 billion private valuation. Anthropic plans to pitch investors on a total addressable market of more than $30 trillion and is considering allowing some shareholders to sell stock with lockups longer than 180 days. Anthropic would reach public markets before OpenAI, which is not planning to list until 2027.
Anthropic has secured at least 14.8 gigawatts of new compute since October at a potential decade-long cost of $517 billion. Suppliers including Amazon, Microsoft, and Nvidia have partly financed Anthropic through investment deals tied to infrastructure commitments: Amazon announced $5 billion in new investment with up to $20 billion more alongside a compute commitment exceeding $100 billion; Microsoft and Nvidia committed up to $5 billion and $10 billion respectively, while Anthropic agreed to buy $30 billion of Azure capacity. Claude runs across AWS Trainium, Google TPUs, and Nvidia hardware, with up to 2 gigawatts of AMD systems planned from 2027.
Anthropic's governance structure draws attention as it prepares to go public. An independent Long-Term Benefit Trust holds the authority to appoint or remove directors and receives advance notice of major company actions, including new AI model launches. Trust-appointed directors constitute a majority of Anthropic's board, and the trust holds no equity in Anthropic. Anthropic plans to preserve the trust's role after going public. Whether that authority will hold when safety considerations conflict with the financial interests of public shareholders remains untested, as no such conflict has occurred.
Ramp billing data from 70,000 companies shows Opus 4.8 accounting for 28% of Anthropic model spend while Fable 5, its flagship model, sits at only 8%, with high cost cited as a factor limiting uptake. Claude Code is cited as one of Anthropic's most popular products. The Trump administration cut off Anthropic's Defense Department contracts after Anthropic refused to give the military unrestricted access to its models.
OpenAI President Greg Brockman said Anthropic surpassed OpenAI on annualized revenue because OpenAI focused on coding competition benchmarks rather than real-world developer workflows, citing gaps in handling messy codebases, model personality, developer experience, customer relationships, and go-to-market execution. Brockman said 'we started late, but our trajectory has been very steep.' OpenAI's annualized revenue exceeded $40 billion after jumping 35% in the quarter, boosted by the GPT 5.6 launch in July.
Reporting on September 6 placed Anthropic's IPO marketing window at mid-October, later than the late-September or early-October window previously reported, and said the company is arranging a $15 billion revolving credit facility.
Morgan Stanley, Goldman Sachs, and JPMorgan are leading the offering; bankers told investors Anthropic could raise more than $100 billion at a valuation near $2 trillion.
Ars Technica reporting on September 4 added that Anthropic's Long-Term Benefit Trust holds no equity in the company and that Anthropic plans to preserve the trust's governance role after going public, adding specificity to the investor questions around a structure in which Trust-appointed directors already hold a board majority.
On September 4, details of Anthropic's IPO governance structure emerged: an independent Long-Term Benefit Trust holds authority to appoint or remove board directors and receives advance notice of major decisions including model launches, with Trust-appointed directors already a board majority, though whether that authority survives conflict with public shareholder financial interests is untested.
Separately, OpenAI President Greg Brockman publicly attributed Anthropic's annualized revenue lead to OpenAI having focused on coding competition benchmarks rather than developer workflows and go-to-market execution.
