Anthropic picks Nasdaq for its planned IPO listing

Business Insider (Katie Roof, 13 September 2026) reported that Anthropic has selected the Nasdaq for its potential IPO, according to a person familiar with their plans. The company has been targeting an October listing.

This is anonymous-source reporting about an exchange choice. It is not a public S-1 filing, not a priced IPO, and not a company press release. Anthropic's IPO filing has not yet been made public.

Nasdaq also secured the SpaceX listing earlier in 2026, a deal valued at $1.75 trillion in the same report. Some estimates have put Anthropic at $2 trillion, though that figure has not yet been finalized. Valuation chatter is a market estimate, not a locked IPO price, and October is a target, not a completed listing.

The timing sits against OpenAI CEO Sam Altman saying it would be ill-advised for OpenAI to go public amid existential-risk controversy, including a former Anthropic employee warning of greater than 10% human extinction risk. Historically the NYSE won many of the largest listings. Nasdaq remains strong in tech, including Cerebras and Rivian, and a Nasdaq listing is a prerequisite for Nasdaq 100 inclusion.

Anthropic will need to release its financials at least 15 days before it begins its investor road show. Market-maker and opening-price mechanics differ between the exchanges. Nasdaq had technical issues on Facebook's 2012 IPO day.

Same-week capital tape includes SoftBank's $11.9 billion loan to keep funding OpenAI. Separate market-structure tape includes the final CLARITY Act text before the 15 September Senate vote.

If you underwrite, allocate, or cover AI IPOs, mark Nasdaq as Anthropic's intended venue and wait for financials at least 15 days before a road show. There is no priced deal to book this week.
