Anthropic’s S-1, read in two columns
01 — Four Things
There are four things that we would like any investor in Anthropic to understand: the incredible potential of AI, the risks we must address, Anthropic's unique approach to building a company and operating in the world, and the ways in which our behavior may differ from that of a purely profit-maximizing company.

It is Anthropic's thesis that the exponential in cognition is likely to continue, eventually reaching the level of what we have called "a country of geniuses in a data center"—millions of virtual agents with the ability to revolutionize every area of human endeavor: software, physics, math, biology, medicine, finance, economics, commerce, robotics, military and intelligence capabilities, and much more.

We expect our revenue growth rate to decline over time. In addition, because the AI industry is very nascent, we have struggled to accurately forecast our revenue in the past and may struggle to do so in the future.

As a result, we may not identify a significant acceleration in our rate of development until after it has occurred.
Risk factors · S-1 p.39
Inside the company
Each version of a Claude model assists in building the next, helping to compress development timelines and produce compounding improvements in the speed at which we innovate. We refer to this recursive dynamic as "closing the loop," and we believe it is one of the most significant structural advantages in frontier AI and can greatly accelerate the rate at which capabilities advance.

Virtual Collaborator
an AI system that works alongside humans to perform complex, multi-step work at professional levels.
Business · S-1 p.192
Ultimately, millions of Virtual Collaborators can run in parallel, each working independently on unrelated problems or collaborating seamlessly to achieve a shared objective. The result is something without historical precedent: what we refer to as a country of geniuses in a data center, available to every organization and sector of the economy.

Results, as the case studies state them
The same filing, on the loop’s risks.
As we increasingly leverage Claude to accelerate progress within Anthropic, our organization may lose visibility across certain processes in a way that may become difficult for any individual or group of humans to understand and control. Because our models write a large and growing share of our code and increasingly perform our research, including our safety research, misaligned behavior in internal use could undermine that work, introduce vulnerabilities into our systems or into the training of future models, or result in models operating outside of our intended controls.
Risk factors · S-1 p.59
Using AI to help build more capable AI could also pose a considerable safety risk, particularly if it sharply accelerates the pace of progress.
Business · S-1 p.195
04 — The Bet
In the first category, Anthropic will often make forward investments (especially in compute) that may seem irresponsibly large at first glance.
founders’ letter · S-1 p.9
We manage compute as a single, fungible pool from multiple strategic partners, and we dynamically direct available compute between workloads based on where the marginal unit is expected to be most productive at any given time.

Compute is procured and committed in advance and the expense is incurred as it is brought online and added to our fungible pool, often in large, discrete steps. The fungible pool can support all workloads dynamically, including research, model development, serving customers, and internal usage of Claude. As a result, there is a lag between when investment is committed and when the full revenue associated with such investment is realized.
management’s discussion and analysis · S-1 p.144
Additionally, we have in the past sought quantities of compute from CSPs in excess of what those partners were willing to provide.
risk factors · S-1 p.41
In the past, we have significantly underestimated our compute requirements, which left us capacity constrained and impacted both product development and deployment.
risk factors · S-1 p.42
Our relationships with our strategic partners—whether with these CSPs, who simultaneously serve as our investors, customers, distribution partners, and competitors, or with Broadcom, which simultaneously serves as a supplier and lessor—create potential conflicts of interest that are difficult to fully anticipate or mitigate.
risk factors · S-1 p.85
But some level of risk is inherent to the extreme upside possibilities offered by the AI exponential. In general, we will aim to be bold but sane, and to win trust with a track record of successful bets.

No advertising on Claude
We have also committed to keeping Claude free of advertising. Advertising funds much of the modern internet, and it would likely be a large source of revenue for us. But people bring some of their most important work and most personal questions to Claude, and we want Claude's only incentive to be giving them a helpful answer.

We therefore chose not to make it generally available and offered its capabilities to the public (as Claude Fable 5) only after we had built additional safeguards. The delay meant forgoing substantial revenue and ceding ground to competitors (we also gave away around $100 million in Claude credits to cyber defenders), but we believe it was the right decision, and we expect to face similar decisions again as our models grow more capable.

May advance more slowly
Building AI safely may require Anthropic (and ideally the rest of the industry) to modulate the extremely fast pace at which AI capabilities are compounding, especially when this is driven by AI systems building themselves. While progress will still be very fast in absolute terms—potentially much faster than today—there may be times when we choose to advance more slowly than we could in order to make our systems safer, even if that puts us at a competitive disadvantage.

No mass surveillance, no fully autonomous weapons
For example, our usage policy prohibits the use of our models, platform, and applications to develop or operate fully autonomous weapons or to conduct mass surveillance, including mass domestic surveillance, and we have declined to permit such uses based on our Company Purpose, notwithstanding the revenue those or similar uses could generate. Maintaining these limitations has had, and may continue to have, adverse commercial and financial consequences.

- If our judgments or estimates relating to our critical accounting policies prove to be incorrect, our results of operations may be adversely affected.
- If we fail to maintain an effective system of disclosure controls and internal control over financial reporting, our ability to produce timely and accurate financial statements or comply with applicable regulations may be impaired, which may adversely affect our business, financial condition, and results of operations.
- We are exposed to fluctuations in interest rates and currency exchange rates, which could negatively affect our business, financial condition, and results of operations.
Risks Related to our Governance Structure · 72–80 of 88
- Our capital stock structure features certain provisions that are novel or otherwise not common among other corporations with multiple-class structures, and may effectively eliminate the ability of holders of our Class A common stock to influence important decisions, including a change in control.
- Our capital structure will concentrate voting power with the LTBT and the Founder LLC for the foreseeable future and will result in the LTBT and the Founder LLC having voting power that is not derived from or proportionate to economic interests in our company.
- Our governance structure and the adoption of our amended and restated certificate of incorporation may negatively affect the decision by certain institutional investors to purchase or hold shares of our Class A common stock.
- We are considered a “controlled company” within the meaning of the Nasdaq Global Select Market corporate governance requirements, and, as a result, we qualify for, and currently rely on, exemptions from certain corporate governance requirements.
- We operate as a Delaware public benefit corporation. As a public benefit corporation, we cannot provide any assurance that we will achieve our Company Purpose.
- Our focus on the long-term best interests of our company as a PBC, and the duty of our directors to balance the pecuniary interests of our stockholders, the best interests of those stakeholders materially affected by our conduct, and our Company Purpose, may conflict with short-, medium-, or long-term financial interests and business performance, which may negatively impact the value of our Class A common stock.
- As a Delaware public benefit corporation, we may be subject to increased litigation concerning our board of directors’ obligation to balance our stockholders’ pecuniary interests, the best interests of those materially affected by our conduct and our Company Purpose, the occurrence of which may have an adverse impact on our business, financial condition, and results of operations.
- Our amended and restated bylaws will designate a state or federal court located within the State of Delaware as the exclusive forum for substantially all disputes between us and our stockholders, and also provide that the federal district courts will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act of 1933, as amended, each of which may limit our stockholders’ ability to choose the judicial forum for disputes with us or our directors, officers, stockholders, or employees.
- Provisions in our amended and restated certificate of incorporation and amended and restated bylaws could make a merger, tender offer, proxy contest, or other significant corporate transaction difficult, potentially depressing the market price of our Class A common stock.

Every figure and quote from the filing on this page was read from one PDF by LlamaParse, then audited against the parse. Nothing was hand-transcribed. The parse statistics above come from the parser’s manifest and its output file.

A header that spans columns, parenthetical negatives, em-dash nulls and superscript footnotes, parsed into one table: the table the Red Ink chapter rests on.
