Anthropic Prepares for Mega IPO With $15 Billion Credit Facility and $2 Trillion Valuation

Anthropic is now expected to begin marketing its IPO in mid-October at the earliest, according to Reuters. The company had previously been expected to publish its prospectus in early September, but the filing is now likely to come toward the end of the month.

The revised schedule reflects the work still required before the offering can proceed, including regulatory reviews, market considerations, and the completion of its new financing arrangement.

Anthropic has not publicly confirmed the timetable. The people familiar with the plans also cautioned that the schedule could change.

Financing Takes Center Stage Before Anthropic’s IPO

The expansion of Anthropic’s revolving credit facility has emerged as one of the clearest signs that preparations for the Anthropic IPO are advancing.

Bloomberg reported that the company is close to finalizing a roughly $15 billion credit facility, substantially larger than the approximately $2.5 billion five-year facility it secured previously.

Morgan Stanley is leading the latest financing, while Goldman Sachs, JPMorgan, and Citigroup have prominent positions in the lending group. The same four banks are also expected to have leading roles in Anthropic’s IPO, according to Bloomberg.

The size of the new facility is notable. The company had previously targeted around $10 billion, meaning the latest figure would exceed that target by roughly $5 billion.

Barclays and Wells Fargo are also expected to hold important positions in the loan syndicate, with several other major international banks participating. The final terms and allocations remain subject to change.

For Anthropic, the financing provides additional liquidity as it continues to expand its AI infrastructure and commercial operations. It also removes a significant piece of the preparation process ahead of the company’s public filing.

October Becomes the Key IPO Window

Anthropic’s IPO timetable has shifted by several weeks.

Reuters reported that the company is now expected to begin marketing the offering in mid-October, with the listing potentially completed shortly before the U.S. midterm elections in November. Its prospectus, which would provide investors with detailed information about the company’s finances and business, is expected in late September rather than early in the month.

The adjustment is not necessarily unusual for a major IPO. Companies can alter their schedules while responding to market conditions, regulatory requirements, and final preparations.

Anthropic is also expected to hold meetings with analysts following completion of the credit facility. Reuters reported that the company could operate on a tighter timetable than a typical IPO because analysts at major banks already have significant familiarity with the business.

That makes the next few weeks particularly important. The prospectus will move the IPO from private preparations into a much more transparent phase, giving prospective investors their first detailed look at the company’s financial performance and risks.

A Potential $2 Trillion Valuation

The scale of the proposed offering has attracted considerable attention.

People familiar with the preparations have indicated that Anthropic could seek to raise an amount comparable to SpaceX or potentially more. Some investors have discussed a valuation approaching $2 trillion, which would make the company one of the largest businesses ever to enter the public market.

That figure is not an official valuation target from Anthropic.

The company’s latest private funding round provides a more concrete benchmark. Anthropic announced in May that it had raised $65 billion at a $965 billion post-money valuation. The company also said its run-rate revenue had exceeded $47 billion.

A $2 trillion IPO valuation would therefore represent a substantial increase over its most recent private-market valuation.

Whether public investors are willing to support such a price will depend on the financial information contained in Anthropic’s eventual prospectus. Revenue growth, operating costs, infrastructure commitments and the company’s path toward profitability are likely to receive close scrutiny.

Claude Drives Anthropic’s Expansion

Anthropic has built its business around the Claude family of AI models, competing directly with other major developers of generative AI systems.

Its commercial growth has accelerated sharply. Bloomberg reported that the company is currently on track to generate annualized revenue of more than $65 billion, representing more than a sevenfold increase from its pace at the end of 2025.

The company has also expanded beyond general-purpose AI chatbots. Claude Code has become an important part of its commercial strategy, particularly among enterprise customers and software developers.

Anthropic said earlier this year that Claude Code had reached a $2.5 billion annualized revenue run rate and that enterprise customers accounted for more than half of its Claude Code revenue.

That enterprise focus could become an important component of the IPO story because investors are likely to examine how much of Anthropic’s growth comes from recurring commercial demand rather than experimental or consumer usage.

AI Growth Comes With Heavy Infrastructure Costs

Rapid revenue growth is only one side of Anthropic’s expansion.

Frontier AI development requires substantial computing resources, and the company has continued securing additional capacity as demand for Claude increases.

The company has established major infrastructure relationships with Amazon and other cloud providers. It has also been reported to be negotiating large-scale computing arrangements, including a reported $35 billion cloud-computing agreement with Nvidia-backed Lambda.

These commitments highlight one of the central questions surrounding the IPO: how efficiently Anthropic can convert rapidly rising AI demand into sustainable earnings.

The $15 billion revolving credit facility could give the company greater financial flexibility as those infrastructure requirements grow. At the same time, the size of its financing needs demonstrates how capital-intensive the race to develop frontier AI systems has become.

SpaceX Offers a Recent IPO Comparison

Anthropic’s preparations have also drawn comparisons with SpaceX.

Before its record-setting IPO, SpaceX expanded its revolving credit facility from $1.5 billion to $5 billion. Bloomberg reported that the company’s proposed $15 billion facility would be roughly three times larger than SpaceX’s pre-IPO revolver.

The comparison extends beyond the size of the financing.

Banks involved in the credit arrangements can also secure important roles in the eventual equity offering. For lenders, participation in a large IPO can generate significant fees and strengthen their position in investment-banking league tables.

Bloomberg reported that SpaceX’s public debut raised $86.2 billion, including the overallotment, contributing to a strong year for U.S. equity issuance.

Anthropic could now become another major test of whether investor demand remains strong enough to support exceptionally large technology listings.

Anthropic Could Set the Tone for AI IPOs

The significance of Anthropic’s offering extends beyond its own shareholders.

Madrona’s Matt McIlwain recently told Bloomberg that a successful Anthropic debut could help clear the way for other major AI companies, including OpenAI and Databricks, to consider public listings in 2027.

That makes Anthropic something of a market test for the broader AI sector.

A strong reception could give privately held AI companies greater confidence that public investors are willing to value businesses primarily on rapid growth and future potential. A weaker response could have the opposite effect, particularly for companies carrying extremely high private-market valuations.

The broader IPO market is already showing renewed strength. Bloomberg data cited in recent reporting showed that U.S. listings had raised $160.6 billion in 2026, excluding blank-check companies and similar financial vehicles, putting issuance at its highest annual level since 2021.

The Prospectus Will Provide the Real Test

For now, Anthropic’s reported $2 trillion valuation remains an expectation rather than a confirmed IPO price.

The more important milestone will be the company’s prospectus. Once public, the filing should give investors a much clearer picture of Anthropic’s revenue, expenses, capital requirements, customer base, and financial performance.

The late-September filing would also provide the market with more information before the expected October marketing period.

Until then, the $15 billion credit facility offers one of the clearest indications of the scale of Anthropic’s preparations. The financing does not guarantee a successful IPO, but its completion would remove an important hurdle as the company moves toward a potential public debut.

If the revised timetable holds, the AI company could become one of the most closely watched IPOs of 2026—and its performance may help determine whether the current wave of AI enthusiasm can translate into sustained public-market demand.
