Anthropic Files for IPO and Plans Nasdaq Listing Under Ticker ANT

The company's SEC filing reveals fast revenue growth, massive first‑half losses and a tentative November marketing timetable that will gauge investor demand for costly AI businesses.

Overview

  • Anthropic officially filed its Form S‑1 with the SEC on Monday and said it intends to list on Nasdaq under the symbol ANT.
  • The filing disclosed roughly $16.29 billion in revenue for the first half of 2026 and about $80.75 billion in net losses driven largely by the revaluation of convertible securities and rising compute costs.
  • Goldman Sachs and Morgan Stanley are named as lead underwriters and the company and advisers have penciled in a marketing week of Nov. 9 with possible trading before the U.S. Thanksgiving holiday, but those dates and any pricing remain subject to market conditions and regulatory review.
  • Public estimates place Anthropic's valuation in the range of about $1.5 trillion to $2 trillion and suggest a potential capital raise near $100 billion, though those figures are reported and not finalized by the company.
  • The IPO will be a major test of investor appetite for capital‑intensive AI firms because proceeds could fund large compute, data center and talent investments while the filing highlights customer concentration, governance and safety risks that investors and regulators will scrutinize.
