Anthropic, the San Francisco-based developer of the Claude family of AI models, filed its S-1 registration statement on Monday, October 26, 2026, seeking a listing on the Nasdaq Global Select Market under the ticker "ANT." The S-1 is the document a company files with the Securities and Exchange Commission before an initial public offering.

The filing shows revenue of $16.3 billion for the first half of 2026. It also shows a first-half net loss of $80.7 billion. According to market data aggregation of coverage, about $72 billion of that loss is non-cash and tied to convertible notes, meaning most of the headline figure reflects an accounting charge rather than money leaving the company's bank accounts.

Size and valuation

The offering could raise up to $100 billion, according to the same coverage. Anthropic was valued at $965 billion in May. No price range has been set yet, according to market data, which reported that the market debut is targeted for the week of November 16.

The filing landed in a market that had been eager for AI exposure. market data credited the S-1 with helping lift the S&P 500 and the Nasdaq early in the week. Anthropic is also a significant customer elsewhere in the newly public AI economy: a market brief described the company as a major buyer of SpaceX (NASDAQ:SPCX)'s compute capacity, with 90-day early-termination rights.

A rough week to go public

By the end of the week the mood had changed. On Friday, October 30, 2026, Wall Street had its worst day since June. The S&P 500 fell 140.32 points to 7,580.07, the Dow Jones Industrial Average dropped 572.25 points to 51,770.31 and the Nasdaq Composite lost 747.73 points to 25,437.00, its worst session since June 5.

The trigger was a wave of worry about how much cash AI is consuming. Intel (NASDAQ:INTC) warned of cash burn this year and posted its biggest one-day drop on record. Amazon (NASDAQ:AMZN) reported trailing 12-month free Cash Flow of negative $42.4 billion, and Alphabet (NASDAQ:GOOGL)'s third-quarter free cash flow came in at negative $9.1 billion, against expectations of negative $3.5 billion. A market analyst, quoted by market data, noted that "Together, Amazon, Google, Microsoft (NASDAQ:MSFT) and Meta (NASDAQ:META) spent more than $200bn in the third quarter alone," and warned that "the risk is that higher financing costs will absorb more of the cash generated."

That backdrop matters for any AI company asking public investors for money. A senior market analyst said that "strong AI Demand is no longer enough on its own."

How to read the numbers

The S-1 puts two very different figures side by side. Revenue of $16.3 billion in six months shows a Business generating substantial sales. The $80.7 billion loss looks alarming at first glance, but the filing ties the bulk of it to convertible notes, an accounting item that does not consume cash in the same way as spending on data centers or salaries.

Investors will likely focus on the cash portion of the loss, the pace of revenue growth and how the company plans to fund its computing needs. Those are the same questions that hit Alphabet, Amazon and Meta shares this month.

What to watch

The next milestone is a price range, which would show how much Anthropic and its underwriters think the market will pay. The targeted debut in the week of November 16 follows a busy stretch: Apple (NASDAQ:AAPL) reports on Monday, November 2, the midterm elections are Tuesday, November 3, and the October jobs report arrives Friday, November 6. Whether the AI selloff deepens or fades over those weeks could shape demand for the offering.
