Anthropic is preparing for a potential public-market debut in October, with sources indicating that the artificial intelligence company could begin marketing its IPO to investors around mid-month. A listing before the U.S. midterm elections would place one of the technology sector's giants under global scrutiny in the coming weeks. Anthropic is best known as the developer of the Claude family of AI models, which compete with OpenAI's offerings among businesses and consumers.

Because Anthropic remains a private company, no official stock price exists yet. However, according to a September 4 report by Stock Analysis, the secondary-market reference price stood at approximately $1,014.63, while the latest post-funding-round valuation was near $965 billion. A separate estimate put the company's current implied valuation at about $858.6 billion. The spread between these figures reflects the uncertainty inherent in pricing private AI companies before an official listing sets a market benchmark.

Valuation Could Approach $2 Trillion

Sources familiar with Anthropic's IPO timeline say the company will delay the publication of its IPO prospectus by two weeks, pushing it to late September. The prospectus will contain details on the company's financials and risks. The sources stressed that the timeline is not finalized and could still change.

The prospectus delay means mid-October would be the earliest Anthropic could start marketing the IPO, with the listing potentially following days before the upcoming U.S. midterm elections. Some investors have discussed a valuation near $2 trillion as a possible outcome of the listing. The timing near the elections adds a political backdrop to the offering, as market volatility around major political events can influence the window in which large listings are launched.

Financing Plan Adds Momentum

Anthropic plans to finalize the terms of a $15 billion revolving credit facility before moving forward with the IPO process. According to sources, Morgan Stanley, Goldman Sachs, JPMorgan, and Citigroup have taken important roles in both the financing and the offering. The facility would exceed the company's $2.5 billion five-year credit arrangement secured last year. Credit facilities of this kind are commonly arranged ahead of IPOs to give companies liquidity flexibility once public, and the sixfold increase over last year's arrangement signals a substantial scaling of the company's operations.

The offering comes as investors watch a broader wave of potential AI listings. OpenAI has also been rumored to be planning a future initial public offering, raising questions about which firm would reach the markets first. The development follows SpaceX's June IPO, which carried an estimated valuation of $1.77 trillion. Together, these potential and completed listings mark one of the largest pipelines of mega-cap technology debats in recent memory, and the reception of each is likely to be watched as a signal for the others.

Anthropic's IPO could serve as a test of how investors value rapidly expanding AI businesses and their infrastructure requirements. The company's annualized revenues have reportedly crossed $65 billion. At the discussed valuations, the listing would also be a milestone for public-market investors who have had few direct ways to gain exposure to leading AI model developers, most of which have remained private. What to watch next includes the prospectus publication in late September, the final pricing terms, and whether the timeline holds ahead of the midterms.
