Anthropic plans mid-October IPO marketing as listing timing slips toward the midterms

Anthropic, the AI research firm behind the Claude chatbot, could begin marketing an initial public offering as early as mid-October 2026. The distinction matters: mid-October refers to when the roadshow would start, not when the shares would trade. More recent reporting indicates the listing could push to after the November U.S. midterm elections, so the timing is unsettled rather than set.

Valuation talk is running ahead of the process. Investors cited by the Financial Times have discussed a figure as high as $2 trillion, though the FT's own account describes the valuation as not formally fixed. That number is best read as a negotiating anchor circulating among investors rather than a price anyone has committed to, and the gap between chatter and a priced book is where most of the risk in this story sits.

Anthropic is separately weighing the release of a new AI model ahead of the listing, a step read as a competitive response to OpenAI's latest flagship. A fresh model close to an IPO would let the company show technical progress at the moment investors are underwriting its growth, though it also raises the bar for what the listing has to deliver.

Market participants will watch for three things in sequence: whether the roadshow actually opens in mid-October, whether the listing clears the midterms or waits them out, and where the book prices relative to the trillion-dollar talk. An offering of this size would also reset the comparison set for every private AI lab still raising in the private market.
