Reuters reported on 5 September 2026, in a story carried by CNBC, that the launch of Anthropic's initial public offering had shifted toward mid-October. The report named Morgan Stanley, Goldman Sachs, JPMorgan and Citi as among the banks working with Anthropic on the IPO, according to people familiar with the matter. The banks declined to comment.

The report was based on unnamed people familiar with the matter, and the available excerpt did not include a comment from Anthropic. It gave no offering size, valuation, price range, exchange or filing date. The mid-October timing was Reuters' account of where the launch was heading, not a date announced by the company. The report described the four banks as among those involved, so it did not set out the full underwriting group. No confirmation from Anthropic or the banks was reported in the excerpt.

Why it matters

Mid-October launch reported

The report points to a launch in mid-October. That timing is Reuters' account, not a date set by the company.

Named underwriter group

Four large banks are reported as working on the deal. A named group of banks is part of the path from a private mark to a public price.

No terms yet

The available part of the report states no offering size or valuation. Until terms are disclosed, there is no public price to compare with the last private round.
