Anthropic IPO Nears With $15 Billion Revolver

Anthropic PBC (P-ANTH) is preparing for its IPO and plans to publish a public prospectus after Labor Day on Sept. 7, 2026. The company has arranged a reported $15 billion revolving credit facility led by Morgan Stanley to support a planned late-September or early-October listing.

Revolving Credit Facility and Bank Syndicate

Anthropic, the artificial-intelligence lab behind the Claude chatbot, is finalizing an expanded revolving credit facility as a committed bank credit line. This facility will provide liquidity and capital flexibility to fund capital expenditure and working capital needs while reducing immediate equity dilution ahead of the IPO.

Morgan Stanley leads the credit facility process, with Goldman Sachs, JPMorgan Chase, and Citigroup serving as prominent arrangers. These banks are also expected to lead underwriting for the offering. The syndicate includes Barclays and Wells Fargo, along with a broader group of global banks such as Bank of America, Deutsche Bank, Royal Bank of Canada, UBS, Bank of Montreal, BNP Paribas, Crédit Agricole, Mizuho, Mitsubishi UFJ, Sumitomo Mitsui, and Toronto-Dominion Bank.

Anthropic reportedly asked the most active banks to commit about $1.25 billion each, a secondary tier around $1 billion, and smaller roles down to roughly $750 million. This planned expansion significantly exceeds the $2.5 billion, five-year revolver the company secured in 2025 and surpasses an earlier internal target of about $10 billion.

IPO Timing, Valuation, and Shareholder Plans

Anthropic confidentially filed a draft S-1 registration statement with the U.S. Securities and Exchange Commission on June 1, 2026. The company has said any IPO will depend on market conditions and other factors. It plans to release a public prospectus after Labor Day and hold an investor day in mid-September ahead of a late-September or early-October listing.

The company closed a private funding round in late May 2026 that raised about $65 billion and implied a post-money valuation near $965 billion. Reporting indicates Anthropic may seek fundraising and a valuation comparable to or larger than SpaceX’s IPO.

The prospectus may allow some existing shareholders to sell shares in the offering and could include extended lock-up periods and scheduled selling programs to mitigate post-IPO trading volatility. These measures aim to manage liquidity and distribution as Anthropic approaches the public markets.

Anthropic’s financing moves, including the large revolver and concentrated underwriting syndicate, signal a near-term funding plan that provides optionality on timing and scale for the public debut. The size and placement of the financing make Anthropic’s expected listing the dominant event on the U.S. IPO calendar after Labor Day.
