The Claude developer, Anthropic, had previously been expected to release its IPO prospectus in early September. The document is now expected toward the end of September, followed by investor marketing in October. The company has not publicly confirmed a listing date, and the timetable could still change.
The delay comes as Anthropic is also finalizing a $15 billion revolving credit facility, according to Bloomberg. The financing would significantly expand the company’s existing borrowing capacity and represents another major step in its preparations for life as a public company.
Morgan Stanley is leading the syndicated credit facility, with Goldman Sachs, JPMorgan, and Citigroup among the major banks involved. Several of the same institutions are also expected to play prominent roles in the IPO process.
Anthropic IPO Moves Toward October
The revised schedule places Anthropic’s potential public debut among the most closely watched AI IPOs of 2026.
Reuters reported that Anthropic now expects to begin marketing the offering around the middle of October, with the listing potentially taking place shortly before the U.S. midterm elections in November. The company had previously been preparing for a faster timetable, with its prospectus expected as soon as early September.

The shift does not necessarily indicate a fundamental change in Anthropic’s IPO plans. Instead, the company is using additional time to address regulatory requirements, complete financing arrangements and assess market conditions before presenting the offering to investors.
Neither Anthropic nor the banks involved have publicly commented on the revised schedule, according to Reuters.
The timing is particularly important because Anthropic would be entering the public markets during a period of heightened investor attention toward artificial intelligence companies. The offering could provide one of the clearest tests yet of how public-market investors value rapidly growing AI businesses.
$15 Billion Credit Facility
A central part of Anthropic’s preparations is the expansion of its revolving credit facility to approximately $15 billion, Bloomberg reported.
The planned facility is substantially larger than the company’s previous borrowing line of roughly $2.5 billion. It also exceeds an earlier target of around $10 billion, underscoring the scale of the company’s financing needs as it expands its computing infrastructure and prepares for a public listing.

Morgan Stanley is leading the financing, while Goldman Sachs, JPMorgan, and Citigroup have significant roles in the banking group. Those institutions are also involved in preparations for Anthropic’s IPO, creating an overlap between the company’s financing and public-market strategy.
The structure has drawn comparisons with SpaceX’s approach to financing ahead of its own massive public offering. Bloomberg previously described Anthropic’s pre-IPO financing as part of a broader trend in which large private technology companies are securing substantial credit facilities before accessing public markets.
For Anthropic, the facility provides additional financial flexibility at a time when operating an advanced AI business requires substantial spending on computing power, data infrastructure, and research.
Anthropic’s Rapid Revenue Growth
Anthropic enters the IPO process after a sharp increase in commercial activity.
The company said in May that it had raised $65 billion in Series H funding at a $965 billion post-money valuation. Anthropic also reported that its run-rate revenue had surpassed $47 billion at the time.
That figure represents a dramatic increase from earlier stages of the company’s development. In February, Anthropic reported $14 billion in run-rate revenue when announcing its $30 billion Series G financing. It said the number of customers generating more than $1 million in annualized revenue had grown from about a dozen two years earlier to more than 500.
The company’s business is centered on Claude, its family of AI models, as well as products such as Claude Code. The company has increasingly targeted enterprise customers and developers, areas that could become important to investors assessing the company’s revenue durability.
Anthropic said in May that Claude Code had surpassed a $2.5 billion annualized revenue run rate, while enterprise use accounted for more than half of its Claude Code revenue.
$2 Trillion Valuation in Focus
The potential Anthropic has delayed its expected IPO launch to mid-October as the AI company navigates regulatory reviews, market conditions, and final preparations. is another major factor surrounding the IPO.
Reports have suggested that investors could value the company at around $2 trillion, although Anthropic itself has not publicly set a target valuation. Such a figure would put the company among the world’s most valuable businesses and potentially above SpaceX’s reported $1.77 trillion valuation following its 2026 IPO.
The company’s most recent official funding round valued the company at $965 billion, meaning a $2 trillion public-market valuation would represent a substantial increase in just a few months.
The valuation debate will ultimately depend on the financial information disclosed in Anthropic’s public IPO prospectus. Investors will be able to assess revenue growth, operating expenses, infrastructure commitments, cash requirements, and profitability in greater detail once the filing becomes public.
That disclosure will be particularly important because frontier AI development remains an expensive business. Training and operating advanced models requires significant computing resources, while demand for AI services is simultaneously encouraging companies to commit billions of dollars to additional infrastructure.
AI Infrastructure Expansion
Anthropic has continued expanding its computing capacity ahead of the expected IPO.
In late August, Reuters reported that Anthropic signed a $35 billion cloud-computing agreement with Lambda, backed by Nvidia. The arrangement is designed to provide access to substantial computing capacity for Claude and Claude Code.
The company has also expanded its relationship with Amazon. Anthropic said in April that its run-rate revenue had surpassed $30 billion and that rapidly increasing demand for Claude was putting pressure on its infrastructure. Its agreement with Amazon was intended to add as much as 5 gigawatts of additional compute capacity over time.
These commitments illustrate why access to financing has become an important part of the company’s strategy. The company needs to balance accelerating demand for AI services with the substantial capital required to support that growth.
What the Anthropic IPO Could Mean for AI
A successful Anthropic IPO could have implications beyond the company itself.
Madrona’s Matt McIlwain has said that a strong public-market debut for Anthropic could help create a path for other major private AI companies, including OpenAI and Databricks, to pursue listings in 2027.

That possibility would make Anthropic’s offering an important reference point for investors and other AI companies considering the public markets. If investors support the company’s valuation and growth profile, other private AI businesses could gain greater confidence in pursuing IPOs.
Bloomberg has also highlighted improving returns on AI investment, or ROAI, as an important factor behind the renewed interest in public listings. The argument is that AI startups are increasingly demonstrating commercial applications that can translate large technology investments into measurable business value.
Still, the public market will ultimately judge these companies on financial performance rather than private-market expectations.
A Closely Watched Public Debut
Anthropic’s IPO will arrive after a year of unusually large technology listings, with SpaceX’s debut establishing a new benchmark for the size of a public offering.
Bloomberg has noted that the performance of major 2026 IPOs could influence investor appetite for additional technology listings. SpaceX’s shares have also come under pressure after its debut, highlighting the risks facing companies entering public markets at exceptionally high valuations.
For Anthropic, the next major milestone is therefore the publication of its IPO prospectus. That filing should provide investors with the detailed financial information needed to evaluate the company’s rapid expansion and the sustainability of its business model.
For now, the company appears focused on completing its financing arrangements and preparing for a potential October offering. The $15 billion credit facility, alongside the expected late-September prospectus, places Anthropic closer to the public markets while giving investors a clearer indication of the scale of the AI company’s financial ambitions.
If the current schedule holds, Anthropic’s October IPO could become one of the defining technology market events of 2026.
