Anthropic's Pentagon ban stands on appeal, and its IPO carries $518 billion of locked compute bills

A federal appeals panel ruled 2-1 on September 25, 2026↗, that the Pentagon had "ample support" to brand AnthropicPVT$350B — Anthropic, private, latest valuation $350B a supply chain risk and keep Claude out of defense systems and contractors' workflows, weeks before an IPO that Reuters says could value the company at $2 trillion↗ ¹²³. It was the first time the 2018 statute, written to catch hostile foreign suppliers, had been turned on a U.S. company, and bad motive was not required: Claude's refusals, which "on more than one occasion" stopped tasks requested by government users, were enough ¹⁴. The fight began in February when Anthropic declined to lift Claude's limits on autonomous weapons and mass domestic surveillance ⁵. Judge Karen Henderson dissented that Congress aimed the law at "hostile nation state" infiltrators ¹.

A statute for foreign saboteurs, aimed at an American lab

The ruling covers defense procurement, not the federal government as a whole ². Two weeks later, on October 8, Anthropic committed $150 million over three years to put Claude inside more than 15 civilian agencies↗, NASA and the NIH among them, under the Energy Department's Genesis Mission ⁶. The same government that strips Claude from weapons workflows now runs it on science.

The ban stops at the Pentagon's gate

Anthropic says the blacklist has cost billions↗ and dented its name ahead of the listing, which Reuters says may wait until after the November midterms ⁵⁹. The bill side does not wait, per a prospectus Reuters has seen: $518 billion in decade-long commitments, about 80% non-cancelable or payable regardless of usage, with Google ($111.1B), Amazon▲+2.85% — Amazon, up 2.85 percent today ($110B) and Microsoft▲+2.34% — Microsoft, up 2.34 percent today ($31.4B) on the hook; if actual spend falls short, Anthropic must pay Google the difference ⁷. Broadcom▲+0.76% — Broadcom, up 0.76 percent today holds $161.2B in largely non-cancelable equipment leases and lends up to $42B more against a $125.2B TPU lease↗, a double role the prospectus itself flags as a conflict ⁷⁸. Revenue reached nearly $4.6B in 2025 against a $42B net loss, mostly a $34B accounting charge, and the run rate passed $65B by July ⁹¹⁰.

The bills are fixed while one wallet closed

The bull case is real compounding: a $9B run rate at the end of 2025 became $47B by May, against risk factors that warn of concentration: nearly a quarter of 2025 revenue came from two customers, and many of Anthropic's largest clients are not locked into long-term contracts ⁹. A California judge has already voided the broader federal ban↗, and practitioners expect Anthropic could win before the full D.C. Circuit, if that court agrees to hear the case ¹⁴.

The hole IPO buyers have to price

No published figure sizes the defense revenue the ruling forecloses; the designation is Anthropic's alone, so the defense spending it shuts stays open to rivals ¹². The hole is whatever the order book says it is. Broadcom is Anthropic's landlord, its lender and, if the notes convert, its shareholder ⁸. Anthropic is "considering all options, including further review" ¹⁵; the trade now turns on whether the full D.C. Circuit agrees to hear the case, and on what buyers pay for a franchise with its defense lane shut.
