Anthropic Scores Monster $13 Billion Series F at a $183 Billion Post-Money Valuation

Six months after disclosing a $3.5 billion raise, Anthropic has confirmed a $13 billion Series F as well as a staggering $183 billion post-money valuation.

The AI giant just recently announced that ICONIQ Capital-led round, which was “co-led” by Fidelity Investments and Lightspeed. Unsurprisingly, given the massive sum, the Series F attracted a variety of other participants to boot.

Those investors include but certainly aren’t limited to Goldman, TPG, BlackRock, Blackstone, and the Qatar Investment Authority. Also unsurprising is that the Claude developer took the opportunity to tout its evidently breakneck revenue and client-base growth.

As described by Anthropic – which carried a $61.5 billion valuation at the time of its March 2025 raise – it currently boasts north of 300,000 business customers. And after hovering around $1 billion at the top of 2025, the company’s run-rate revenue is said to have surpassed $5 billion last month.

Without diving too much deeper into the victory lap here, Anthropic indicated that the new tranche will enable continued enterprise buildouts, enhanced “safety research,” and ongoing global-expansion initiatives.

Not directly mentioned is that the fresh funding and the entity’s operational trajectory could well drive (or at least contribute to) additional copyright-litigation settlements.

By now, many are aware that August saw Anthropic confirm a pre-trial resolution in class-action litigation levied by authors.

Admittedly, there are a few key differences between that complaint and major music publishers’ still-active action. Just in passing, the authors’ suit received class certification despite Anthropic’s opposition and was barreling towards a December 2025 trial.

On the other hand, the music-space suit is plodding along and, at the earliest, may head to trial about 13 months from now. Plus, the authors’ surviving claims centered on alleged book piracy as opposed to the process of using books for training; a definitive answer to the ever-important fair use question has yet to materialize.

It probably won’t come as a shock that the publisher plaintiffs are looking to modify their own allegations based on the authors’ suit’s evidence and settlement.

“The facts of Anthropic’s additional unlawful acts are now beyond dispute, based on the new evidence disclosed in Bartz v. Anthropic,” the publishers wrote yesterday as part of a push for leave to file an amended complaint.

“Nor is there any question that the millions of books Anthropic illegally torrented included a vast trove of Publishers’ copyrighted lyrics, as is revealed by even a cursory review of the books Anthropic is now known to have pirated,” they continued.

“The only question now is whether Publishers will be permitted to amend their Complaint to address this critical new evidence of Anthropic’s infringement—or whether Anthropic will succeed in evading liability for its illegal torrenting by exploiting its own discovery misconduct,” the publishers penned.

As summarized, there are noteworthy differences between the cases. But at the top level, with one settlement already wrapped, it hardly seems outside the realm of possibility that Anthropic will also move to put separate copyright battles in the rearview.
