Anthropic, the company behind the Claude AI models, filed an amended Form S-1 with the SEC on Monday, November 2, 2026. The original filing a week earlier only ran through June 30. This one adds the quarter ended September 30, and the numbers landed while the market was already trading on Big Tech's AI spending.

The headline is a big quarter with a less tidy story underneath. The price range and share count in the prospectus are still blank, so there is no IPO price or valuation in the filing itself.

A Bigger Quarter, a Slower Climb

| Item | Q3 2026 | Q2 2026 | Revenue$16.96 billion$11.56 billion Operating income (loss)loss of $567 millionincome of $974 million | Net loss | $23.29 billion | $66.3 billion |

Figures from Reuters. For the nine months through September, CNBC reported revenue of $33.24 billion, up about 1,200% from a year earlier, and a net loss of $104 billion, most of it from changes in the fair value of convertible notes and derivative liabilities.

Revenue is still climbing fast, but the pace is slowing. CNBC put quarter-over-quarter growth at about 47% in Q3, down from 144% in Q2 and 132% in Q1. For a stock that will be priced on growth, that slowdown matters more than the size of any single quarter.

The filing also explains why the operating profit vanished. According to Yahoo Finance, demand outran the capacity Anthropic had booked ahead, so it bought about $5 billion of short-term computing that "currently costs significantly more" than its long-term contracts. A $2 billion non-cash charge tied to a donation-matching program added to the loss. Price cuts and discounts took about $600 million off third-quarter revenue, and the company estimates 5% to 7% of revenue in the first nine months came from customers breaking its usage policy or commercial terms. It warned that stricter enforcement may reduce future revenue and growth rates.

The $895 Billion Bill and Who Collects It

Anthropic disclosed purchase commitments and leases totaling about $895.4 billion, "substantially all" for compute and infrastructure. Yahoo Finance reported about $70 billion of that comes due within a year and nearly $450 billion by the end of 2030. It compared the total with roughly $132 billion of cash and short-term investments at the end of September, almost seven times as much.

Yahoo listed the largest counterparties:

  • Broadcom (AVGO): about $161 billion in equipment leases
  • Alphabet's Google (GOOGL): about $121 billion, up from $114.5 billion in the first filing
  • SpaceX's AI unit (SPCX): up to $120.5 billion
  • Amazon (AMZN): $110 billion
  • It also reported a plan for another $125 billion to $150 billion of Google chips and more than $20 billion of spending with AMD. Those deals have no fixed dollar commitment, so they are not part of the $895 billion.

    Why Partner Stocks Carry the Options Story Today

    ANT doesn't trade yet, so for now the filing shows up in the options of the companies Anthropic pays. Reuters noted Amazon up 4% and Alphabet up 2.1% after the filing. Those moves came on a day of broad tech buying, so it's hard to say how much was the filing and how much was the bounce.

    A few educational points on how traders look at that link:

  • Backlog is not the same as revenue. A large commitment from one customer can support a supplier's growth story, but it also concentrates risk. A filing that shows the customer losing money on operations makes some traders weigh counterparty risk alongside the headline number.
  • Proxy trades come with noise. AMZN, GOOGL and AVGO options react to their own earnings, rates and the wider AI trade. Using them as a stand-in for an IPO that hasn't priced means taking on all of that risk too.
  • Watch implied volatility, not just price. If a partner stock's implied volatility climbs into the IPO window, buying premium costs more. Comparing implied volatility with recent realized moves, as explained in our implied volatility primer, is one way to judge whether an option is pricing in more than the stock has actually been moving.
  • Retail Allocation, Dilution and the Blanks

    The amended filing says some shares will be offered through Charles Schwab, Fidelity, Robinhood, SoFi and Morgan Stanley's E*Trade, per Yahoo Finance. Retail access can add to first-day trading interest, which is one reason brokers like HOOD and SCHW sometimes trade on big IPO news.

    It also shows potential dilution: about 1.77 billion stock options outstanding and up to 2.95 billion shares reserved for a new equity plan. Reuters reported that some current and prospective investors now value Anthropic at about $1.5 trillion, down from roughly $2 trillion. That is a press report, not a number in the filing.

    The Steps Before ANT Options Can Trade

    The filing doesn't change the order of events. Anthropic still has to file a price range and share count, run its roadshow, price the deal and start trading on Nasdaq under "ANT." Options can be added only after that, once the stock meets the exchanges' listing standards. Because nothing is set yet, it's too early to say which expiration months would come first or how high their implied volatility might start.

    When they do list, the usual new-listing pattern is high implied volatility that can fall quickly as the stock settles. That makes early long options expensive and early short options risky.
