Anthropic Files for Nasdaq IPO, Discloses $16.3 Billion Revenue and $80.7 Billion Half-Year Loss

Anthropic, the maker of the Claude chatbot, filed a registration statement with the U.S. Securities and Exchange Commission on October 26 for a proposed initial public offering. The company said it plans to list its Class A common stock on the Nasdaq Global Select Market under the ticker symbol ANT. No listing date or share price range has been set yet.

The filing shows revenue of $16.3 billion for the six months ended June 30, 2026, up from $1.16 billion in the same period a year earlier. Second-quarter revenue alone came to $11.6 billion, according to the prospectus.

Alongside that growth, Anthropic reported a net loss of $80.7 billion for the first half of 2026. The company said about $72.4 billion of that figure was a non-cash charge tied to changes in the fair value of convertible notes, derivative liabilities and SAFE agreements, instruments whose carrying value rises as the company's valuation climbs. Anthropic has not distributed cash to settle these obligations; the figure is an accounting entry rather than money spent.

On an operating basis, which excludes those fair-value swings, the picture looked different: the operating loss for the half narrowed to $693 million from $2.1 billion a year earlier, and the second quarter alone showed operating income of $974 million.

The filing also disclosed $6.2 billion in convertible notes held by Amazon as of June 30, underscoring the scale of Amazon's financial stake in the company. Amazon and Google have both invested in Anthropic as part of broader cloud and chip partnerships.

Reuters reported that some current and prospective investors were valuing Anthropic at around $1.5 trillion following the filing, down from roughly $2 trillion a week earlier. Anthropic itself has not stated a valuation, and the figures reflect informal investor estimates rather than a price the company has set.

Because the registration statement has not yet been declared effective, the timing of an actual stock market debut remains unconfirmed. Anthropic competes with OpenAI, Google and other large AI developers, and its filing is being watched as an early test of how public markets will price a frontier AI lab's mix of fast revenue growth, heavy spending and large paper losses.
