Woofun AI reports that Anthropic is negotiating with multiple banks to increase its existing $2.5 billion revolving credit facility by several billion dollars. This expansion aims to secure additional liquidity ahead of an initial public offering, with Goldman Sachs, Morgan Stanley, JPMorgan Chase, Citigroup, and Barclays serving as current providers. The company plans to meet with public market investors in the coming weeks to determine offering size and valuation. While some reports suggest a September listing with a valuation exceeding $1 trillion, other sources indicate October as the earliest possible date, with final arrangements pending confirmation. Similar credit line expansions were previously observed with SpaceX and Cerebras prior to their public listings.
