Usable claims

• Anthropic, PBC filed its Form S-1 registration statement with the U.S. Securities and Exchange Commission on Monday, October 26, 2026 (calendar-verified; EDGAR Filing Date 2026-10-26, Accepted 2026-10-26 09:00:11, registration no. 333-299633; the cover header itself reads 'As filed with the Securities and Exchange Commission on October 26, 2026.'). TechCrunch (Rebecca Bellan; published_time 2026-10-26T14:35:22+00:00) framed the filing: 'After weeks of leaked S-1s, Anthropic finally filed for an initial public offering on Monday, setting the stage for one of the most closely watched public debuts in modern U.S. history.' The filing's own financial sentences: 'Our revenue was $16.3 billion for the six months ended June 30, 2026, up from $1.2 billion for the six months ended June 30, 2025. Our operating loss was $693 million for the six months ended June 30, 2026, down from $2.1 billion for the six months ended June 30, 2025.'; elsewhere the filing adds that H1 2026 revenue represented 'a year-over-year growth rate of 1,300%.'; on net losses: 'We have incurred net losses in each year since our founding, including a net loss of $1.5 billion, $8.3 billion, and $42.0 billion for the years ended December 31, 2023, 2024, and 2025, respectively, and $80.7 billion for the six months ended June 30, 2026, and we may not achieve or sustain profitability in the future.' — with the filing's own driver sentence 'These net losses included change in fair value of convertible notes, derivative liabilities, and SAFEs of $1.0 billion, $5.4 billion, and $34.3 billion for the years ended December 31, 2023, 2024, and 2025, respectively, and $72.4 billion for the six months ended June 30, 2026, primarily driven by an increase in the fair value of our outstanding convertible promissory notes' (the income statement's line shows (72,388) — in millions, i.e. $72.4 billion — matching the sentence, our count of the table; TechCrunch renders the driver as 'largely driven by noncash accounting adjustments tied to convertible debt'). Per the filing: 'Proposed trading symbol "ANT"' and 'applied to list our Class A common stock on the Nasdaq Global Select Market under the symbol “ANT.”' — an application, not a completed listing. Customer scale, per the filing's own bullets as of September 30, 2026: 'More than 11,900 customers with $100,000 or more of revenue on a TTM basis', 'More than 1,900 customers with $1 million or more of revenue on a TTM basis', and 'Approximately 250 customers with $10 million or more of revenue on a TTM basis.' Cross-product usage: 'For the three months ended September 30, 2026, over 50% of our customers with $100,000 or more of revenue on a TTM basis used Claude Platform and at least one of our first-party applications, up from approximately 30% for the three months ended December 31, 2025.' Retention: 'The value that Claude delivers to customers has helped drive our Net Revenue Retention of approximately 900% as of September 30, 2026.' Claude Code spend spread, per the filing: 'For example, in the three months ended September 30, 2026, Claude Enterprise users who did not use Claude Code spent less than $75 per month on average, while the top 5% of Claude Enterprise users who used Claude Code spent approximately 20 times that amount.' The pitch, per the filing: 'Unlike a static product that serves a single use case, Claude is frontier AI with rapidly advancing capabilities.' and 'An advance at any layer compounds across all three layers, accelerating the pace at which we can deliver more capable intelligence.' Governance, per the filing: 'We believe that our seven co-founders, Dario Amodei, Daniela Amodei, Tom Brown, Jack Clark, Jared Kaplan, Sam McCandlish, and Christopher Olah, as a group, are distinctly equipped to be stewards of our mission.'; 'Immediately prior to the completion of this offering, we will issue a single share of Class F common stock, a special class of our common stock, to a limited liability company of which our seven co-founders will initially be the sole members (the “Founder LLC”).'; 'Our Class F common stock, which will be held by the Founder LLC, will be entitled to an aggregate number of votes that equals 50.1% of the total voting power of our outstanding shares of capital stock with respect to matters submitted to stockholders generally, including the election of our directors other than the Class T directors. Our Class F common stock will not have any economic rights.'; and the Long-Term Benefit Trust — 'a financially disinterested trust, which we refer to as the Long-Term Benefit Trust (the “LTBT”) and which generally has the power to elect and remove a majority of the authorized members of our board of directors' — with 'In 2023, we implemented an innovative governance structure featuring the LTBT' (the trust agreement in EX-99.1 is 'effective June 29, 2023'). TechCrunch's governance frame stays TechCrunch's: 'The governance structure is controversial because it means voting power is not proportional to the founders’ economic ownership, and therefore public shareholders will have little practical control over a company building technology that, by its own admission, poses “catastrophic or existential risks to humanity.”' — the quoted risk phrase verified verbatim in the filing ('pose catastrophic or existential risks to humanity, particularly if such systems were misused, replicated, weaponized, or allowed to operate with a high degree of autonomy'). Distribution, per the filing: 'We have a joint go-to-market approach with these CSPs through which we establish direct contractual relationships with our customers while paying a fee to each CSP. This structure allows us to foster stronger commercial alignment with these CSPs, avoid channel conflict, set pricing, and realize the financial benefits of ongoing compute efficiency improvements.'; the new services venture 'We recently launched an AI services company, Ode with Anthropic, in partnership with leading private equity firms to bring Claude’s capabilities to mid-sized companies across sectors, building solutions on the Claude Platform and supporting customers over the long term.' (TechCrunch names Blackstone — 'a separate venture with Blackstone and other private equity firms, dubbed Ode with Anthropic, to embed forward deployed engineers into businesses to build bespoke AI tools with Claude' — the name is outlet-added, the filing says only 'leading private equity firms'). Headwinds, per the filing's own conditionals: 'These CSPs may prioritize their own compute needs or those of their other customers, including competitors in which they have invested, may gain insight into our operations and compute requirements through their roles as providers that could inform their competitive strategies, or may make business decisions' (sentence continues); 'Certain CSPs from which we obtain substantial compute also develop and offer their own AI models and related services. As a result, our commercial relationships with these providers may not always be fully aligned with our long-term interests'; and the customer-concentration risk factor 'Any adverse change in demand from our largest customers, in their ability or willingness to perform under their contracts with us, in applicable laws or regulations, or in our broader strategic relationships with such customers could adversely affect our business and prospects.' Per TechCrunch's second piece (Rebecca Bellan; published_time 2026-10-26T16:49:42+00:00), 'Anthropic did not immediately respond to TechCrunch’s request for comment.' Pre-filing context, per The Decoder (Matthias Bastian, datePublished 2026-10-15T09:50:43+00:00) — the leak era TechCrunch's 'weeks of leaked S-1s' references, every figure inside The Decoder's own attributions and never merged with the filing's numbers: 'Anthropic shared its quarterly numbers with potential investors at a private meeting in San Francisco, according to multiple US media reports. Third-quarter revenue hit $16.8 billion.'; 'The planned IPO, which The Information says is set for November before Thanksgiving, will be the biggest test yet of investor appetite for the AI boom. Anthropic's private valuation jumped to $965 billion in May, up from under $20 billion just two years earlier. Some bankers even floated a $2 trillion IPO.' The filing discloses NO offer size and NO price range; TechCrunch: 'Anthropic hasn’t yet disclosed how much it hopes to raise nor its proposed share price.'
