Founded out of concern for OpenAI: Siblings build a rival – and are now worth $183 billion

In the fast-paced world of artificial intelligence, a new giant has emerged, threatening to overshadow even industry leader OpenAI: Anthropic. Founded in 2021, the startup has catapulted itself into the stratosphere of tech valuations in just four years, reaching a dizzying $183 billion after a recent funding round. But behind these impressive figures lies a story that goes far beyond mere business growth. Founded by former OpenAI executives Dario and Daniela Amodei, Anthropic was born out of a deep concern about the commercial focus of AI development. Their goal: to create an artificial intelligence where safety and ethics are not just added later, but woven into the system's DNA from the ground up.

This article examines Anthropic's meteoric rise and analyzes the key factors behind its success: from its unique "Constitutional AI," which gives the AI ​​model Claude a kind of ethical conscience, to its strategic partnerships with Amazon and Google, and its fierce competition with OpenAI. We delve into the innovative corporate structure with its built-in "kill switch," shed light on a multi-billion-dollar legal battle that nearly brought the company down, and reveal the ambitious, yet unsettling, vision of its founder, Dario Amodei. Discover how Anthropic is not only disrupting the AI ​​market but also raising the fundamental question of how we can safely navigate a future with superintelligent AI.

What makes Anthropic one of the most valuable companies in the world?

What forces enabled a company founded in 2021 to rise to become one of the world's most highly valued startups within just four years? Anthropic has impressively answered this question with its latest funding round. The company raised $13 billion, achieving a valuation of $183 billion. This figure is not only impressive, but it also represents a tripling of the company's valuation compared to March 2025, when it was valued at $61.5 billion.

The Series F funding round was led by ICONIQ, with support from prominent investors including Fidelity Management & Research Company, Lightspeed Venture Partners, the Qatar Investment Authority, Blackstone, and Coatue. These investors represent a broad range of institutional funders who believe in the potential of artificial intelligence and, specifically, in Anthropic's approach.

Who are the minds behind this success?

The story of Anthropic is inextricably linked to siblings Dario and Daniela Amodei. Dario Amodei previously served as Vice President of Research at OpenAI and played a key role in the development of the GPT-2 and GPT-3 models. His decision to leave OpenAI and found his own company stemmed from fundamental disagreements about the strategic direction of AI development.

The Amodei siblings were concerned about the increasing commercialization of AI technologies, especially after OpenAI's partnership with Microsoft in 2019. Their vision was to create a company that puts safety and ethical considerations at the heart of AI development, rather than primarily focusing on rapid monetization.

This philosophy is also reflected in the company's unique structure. Anthropic operates as a Public Benefit Corporation (PBC) and has implemented a special governance structure. The Long-Term Benefit Trust holds special "Class T" shares, which allow the PBC to appoint and dismiss three of the five directors. This structure acts as a kind of "kill switch" mechanism to intervene should AI development drift in a dangerous direction.

How does the Constitutional AI concept work?

What distinguishes Anthropic's approach from other AI companies? Its core concept is called Constitutional AI and represents a fundamental shift in how AI systems are trained. Instead of relying solely on human feedback, Anthropic uses a two-stage process in which AI systems learn to evaluate and improve their own responses based on a defined "constitution" of ethical principles.

In the first phase, the model learns to critically examine its responses and correct them according to constitutional principles. In the second phase, this self-generated feedback is used as a reward signal for a reinforcement learning process, which Anthropic calls “Reinforcement Learning from AI Feedback” (RLAIF).

This constitution is not static but is continuously being developed. Remarkably, Anthropic not only consulted experts in developing these principles but also involved approximately 1,000 US citizens in the democratic process. The core principles include protection from illegal or harmful content, the protection of privacy, the promotion of fairness, and the prevention of discrimination.

What role does Claude play in the competition?

Claude, Anthropic's AI assistant, competes directly with OpenAI's ChatGPT and other leading AI systems. What makes Claude special? The system is distinguished by its exceptionally large context windows – the current version, Claude 3.5 Sonnet, can process up to 200,000 tokens, which corresponds to approximately 150,000 words. In comparison, GPT-4 Turbo supports "only" 128,000 tokens.

One particularly successful example is Claude Code, which has generated over $500 million in annual revenue since its full launch in May 2025. Usage growth in this area increased more than tenfold in just three months. These figures illustrate how quickly specialized AI applications can gain traction in the enterprise sector.

Claude differentiates itself from competing products through its integrated focus on security and ethical guidelines. While other providers often implement these aspects retroactively, they are embedded in Claude's architecture from the ground up. This makes the system particularly attractive for corporate clients in regulated industries such as finance, healthcare, or legal services.

How is Anthropic's business developing?

Anthropic's business development demonstrates impressive momentum. The company increased its projected annual revenue from approximately one billion dollars at the beginning of 2025 to more than five billion dollars in August 2025. This fivefold increase in revenue within eight months underscores the explosive growth in the AI ​​sector.

Particularly noteworthy is the growth of the customer base. The number of large customers increased sevenfold within a year. Krishna Rao, Chief Financial Officer of Anthropic, emphasizes that customers rely on Anthropic's models and platform products for their most important, business-critical tasks. Demand is rising exponentially, enabling this unprecedented growth.

The fresh capital from the latest funding round will pursue three main goals: meeting the growing demand from enterprise customers, deepening security research, and supporting international expansion. The latter point is particularly interesting, as Anthropic has so far focused primarily on the US market.

What strategic partnerships shape the company?

Anthropic's growth is not only organic but also driven by strategic partnerships. Amazon has established itself as one of its most important partners, not only as an investor but also through a formal partnership with Amazon Web Services (AWS). This collaboration provides Anthropic with access to extensive cloud computing resources, which are essential for training large AI models.

Google also invested in Anthropic early on. At the end of 2022, the search engine giant invested $300 million, acquiring a 10 percent stake. This investment gave Anthropic access to Google's massive computing resources and provided an important foundation for further development.

One interesting aspect is the establishment of an advisory board for national security and the public sector. This initiative aims to strengthen cooperation with the US government and allied governments. At a time when AI technologies are increasingly seen as strategically important for national security, Anthropic is positioning itself as a trusted partner for government institutions.

How does Anthropic deal with legal challenges?

The AI ​​industry is increasingly facing copyright lawsuits, and Anthropic is no exception. The company recently reached a landmark settlement with a group of authors who accused it of unlawfully using copyrighted works to train its AI assistant, Claude.

The settlement amounts to at least $1.5 billion and covers approximately 500,000 books. Compensation of around $3,000 is provided for each affected work. This sum is considered the highest compensation ever paid for copyright infringement and could have a ripple effect across the entire industry.

Crucial to the case was the court's finding that while training AI with copyrighted texts might be covered by the US principle of "fair use" under certain circumstances, downloading content from illegal sources was not. The court determined that Anthropic was aware of the data's unlawful origin, which significantly strengthened the legal position.

The settlement allowed Anthropic to avoid a lawsuit that could have resulted in penalties of up to $150,000 per book. This could have led to a total of up to $75 billion, jeopardizing the company's existence.

How does Anthropic position itself in relation to OpenAI?

A comparison with OpenAI is unavoidable, as both companies compete in the field of large-scale language models. OpenAI is currently planning to increase its valuation to approximately $500 billion. This would value OpenAI at half a trillion dollars, significantly higher than Anthropic's current valuation of $183 billion.

Despite these valuation differences, interesting shifts are emerging in the market dynamics. According to investor reports, OpenAI is losing market share while Anthropic is gaining. OpenAI's market share fell from 50 to 34 percent, while Anthropic increased from 12 to 24 percent. However, these figures come from an Anthropic investor and should therefore be interpreted with caution.

The strategic differences between the two companies are becoming increasingly clear. While OpenAI focuses on broad market penetration and rapid commercialization, Anthropic concentrates on security and ethical AI development. This positioning makes Anthropic particularly attractive to enterprise customers in regulated industries where compliance and trust are paramount.

OpenAI is currently working on GPT-5, which is described as "significantly more advanced" than its predecessor. At the same time, Anthropic is continuously developing its Claude family, with versions such as Claude 3.7 Sonnet and the latest Claude Sonnet 4.

What is Dario Amodei's vision for the future of AI?

Dario Amodei's vision for the future of AI is both ambitious and unsettling. In his essay on the "compressed century," he describes the possibility that by 2026 an AI could be developed that is more intelligent than Nobel laureates in several scientific fields combined. This superintelligence could perform the scientific achievements of an entire nation of geniuses in data centers.

However, Amodei also emphasizes the risks of this development. In an interview, he explained that there are two main dangers: AI systems could pursue strategic and dangerous goals, or they could make harmless mistakes in situations where these have serious consequences. Both scenarios could lead to disasters.

Amodei's personal motivation for developing safe AI is deeply rooted in a moving experience: the loss of his father to an illness that later became treatable. This experience made him aware of the positive potential of AI and, at the same time, highlighted the need for responsible development.

Instead of maximizing profits, Anthropic invests all revenue in developing new AI models. This strategy particularly benefits enterprise customers who require more complex applications. Amodei cautions against excessive pessimism and the purely profit-driven mindset that often prevails in the industry.

How is the global AI market developing?

The global AI market continues to show explosive growth, despite occasional doubts about the sustainability of investments. According to PitchBook, funding for US startups increased by 75.6 percent in the first half of 2025, driven by the ongoing AI boom. Total AI startup funding in 2024 exceeded $100 billion, representing an 80 percent increase year-over-year.

Around a third of all venture capital investments now flow into AI startups. US companies continue to dominate the market and receive the majority of these investments. Generative AI is the biggest investment magnet, attracting approximately one-third of all AI investments.

The number of AI unicorns (startups with a valuation of over one billion dollars) has now reached over 50 companies worldwide. Anthropic is among the highest-valued and is now the fourth most valuable unicorn globally, behind only SpaceX, ByteDance, and OpenAI.

What challenges and risks exist?

Despite impressive growth, AI companies face significant challenges. The development costs for the next generation of AI models are astronomical. OpenAI, for example, has raised its spending forecast to $115 billion by 2029. These figures illustrate the enormous capital requirements in the AI ​​industry.

Regulatory challenges are increasingly shaping the valuations of AI companies. With the global implementation of stricter guidelines on data protection, algorithm transparency, and AI ethics, startups with robust compliance strategies are becoming more attractive to investors. Companies that proactively address regulatory concerns are better positioned for long-term success in an increasingly regulated industry.

The question of sustainable unit-cost economics is becoming increasingly urgent. Investors are moving away from hype-driven valuations and focusing on AI startups that demonstrate financial discipline, cost-effective growth, and scalable business models. This trend reflects a more mature investment perspective, where long-term value creation takes precedence over speculative hype.

What impact will Anthropic's success have on the industry?

Anthropic's success sends important signals to the entire AI industry. The company demonstrates that a focus on safety and ethical standards can be not only morally imperative but also commercially successful. This could encourage other companies to pursue similar approaches.

The multi-billion dollar settlement in the copyright lawsuit could have far-reaching implications. As the first significant settlement in a copyright dispute concerning AI training, it could serve as a precedent for future cases. Other AI companies might feel compelled to proactively enter into licensing agreements with copyright holders.

The emphasis on international expansion also demonstrates that the AI ​​market is becoming increasingly global. While American companies have dominated so far, European and Asian markets could gain in importance. Anthropic's plan to expand internationally could trigger new competitive dynamics.

What does this mean for the future of AI development?

Anthropic's story illustrates several important trends in AI development. First, the importance of safety and ethical standards is increasingly recognized by investors and customers. Second, its enormous valuations demonstrate that AI is viewed as a transformative technology with the potential for massive economic impact.

The shift towards more cost-effective and efficient AI models could further transform industry dynamics. Models like DeepSeek have demonstrated that highly optimized architectures can significantly reduce operating costs. This could lead to a democratization of AI technology, giving smaller companies better access to advanced AI capabilities.

The focus on industry-specific AI applications is likely to intensify. Investors are increasingly prioritizing AI startups that solve real-world business problems, rather than developing general-purpose models. This shift is driven by the realization that tailored AI solutions offer better monetization potential and faster market adoption.

The Anthropic story demonstrates that innovation in the AI ​​industry can be driven not only by technological advancements but also by new approaches to corporate governance, ethics, and security. The company has proven that it is possible to achieve both commercial success and maintain high ethical standards—a lesson that should be of importance to the entire industry.
