Where things stand

As of 2 November 2026, the amended prospectus includes third-quarter results and $895.4 billion in commitments. The offer price and share count remain unset.

Anthropic reports $17 billion quarterly revenue and $895.4 billion in commitments

Anthropic updated its IPO prospectus on 2 November 2026. The Claude developer reports nearly $17 billion in third-quarter revenue and a $567 million operating loss.

Net loss reached $23.3 billion, mainly due to financial-instrument revaluations. It therefore does not represent an equivalent cash outflow or only the loss from ongoing operations.

Purchase and lease commitments total $895.4 billion, almost all for computing and infrastructure. About $69.8 billion falls due in the twelve months after 30 September 2026, and $447.5 billion is expected before the end of 2030; part of the remainder extends to 2045. The document says $213.8 billion involves termination rights or prior conditions.

These multiyear commitments are not spending already incurred. The prospectus still leaves the sale price and number of shares unset.

Anthropic files for an IPO without setting a share price

Anthropic filed its Form S-1 with the US securities regulator on 26 October 2026, seeking a Nasdaq listing under ANT. Filing does not mean its public share sale has begun.

Neither the price range nor the number of shares to be offered has been set. The prospectus remains preliminary: securities cannot be sold before the registration becomes effective.

The Claude developer reports $16.3 billion in revenue for the first half of 2026, compared with $4.6 billion for all of 2025, and $9 billion in infrastructure spending during that half-year. These figures show the scale of its business and computing requirements; they establish neither the proceeds of the offering nor its final valuation.
