The company's name was chosen because it "connotes being human centered and human oriented"—and the domain name happened to be available in early 2021.² Anthropic incorporated as a Delaware public-benefit corporation (PBC), a legal structure enabling directors to balance stockholders' financial interests with its stated purpose: "the responsible development and maintenance of advanced AI for the long-term benefit of humanity."¹³

In February 2026, Anthropic closed a $30 billion Series G funding round at a $380 billion post-money valuation, led by GIC and Coatue with co-leads D.E. Shaw Ventures, Dragoneer, Founders Fund, ICONIQ, and MGX.⁴ The company has raised over $67 billion in total funding. At the time of the announcement, Anthropic reported $14 billion in run-rate revenue, growing over 10x annually for three years, with more than 500 customers spending over $1 million annually and 8 of the Fortune 10 as customers.⁴ The company's customer base expanded from fewer than 1,000 businesses to over 300,000 in two years, with 80% of revenue coming from business customers.⁵⁶

History

Founding and OpenAI Departure

Anthropic emerged from disagreements within OpenAI about the organization's direction. In December 2020, seven co-founders departed to start something new: Dario AmodeiPersonDario AmodeiComprehensive biographical profile of Anthropic CEO Dario Amodei documenting his 'race to the top' philosophy, 10-25% catastrophic risk estimate, 2026-2030 AGI timeline, and Constitutional AI appro...Quality: 41/100 (CEO), Daniela AmodeiPersonDaniela AmodeiBiographical overview of Anthropic's President covering her operational role in leading $7.3B fundraising and enterprise partnerships while advocating for safety-first AI business models.

The company formed during the Covid pandemic, with founding members meeting entirely on Zoom. Eventually 15 to 20 employees would meet for weekly lunches in San Francisco's Precita Park as the company took shape.² Dario Amodei later stated that the split stemmed from a disagreement within OpenAI: one faction strongly believed in simply scaling models with more computeParameterCompute (AI Capabilities)This page contains only React component imports with no actual content about compute capabilities or their role in AI risk.

Products and Capabilities

Claude Model Family

In May 2025, Anthropic announced Claude 4, introducing both Claude Opus 4 and Claude Sonnet 4 with improved coding capabilities.¹ Also in May, Anthropic launched a web search API that enables Claude to access real-time information.

Claude Opus 4.5, released in November 2025, achieved state-of-the-art results on benchmarks for complex enterprise tasks: 80.9% on SWE-bench Verified (the first AI model to exceed 80%), 60%+ on Terminal-Bench 2.0 (the first to exceed 60%), and 61.4% on OSWorld for computer use capabilities (compared to 7.8% for the next-best model).¹⁷ Reports show 50% to 75% reductions in both tool calling errors and build/lint errors with Claude Opus 4.5.

Claude Code

Claude Code's run-rate revenue exceeded $2.5 billion as of February 2026, more than doubling since early 2026.⁴ According to Menlo Ventures data from July 2025, Anthropic holds 42% of the enterprise market share for coding, more than double OpenAI's 21%.⁶

Limitations

Claude has several documented limitations. Earlier versions struggled with hallucinations—Sonnet 3 had a 16.3% hallucination rate, though Claude 3.7 Sonnet improved this to 4.4%.¹⁸ Claude models also have a high rejection rate (as high as 70% in some scenarios), which may indicate excessive caution.¹⁹

Unlike some competitors, Claude doesn't support native video or audio processing, nor does it generate images directly—relying on external tools when creation is needed. Claude may occasionally struggle with maintaining consistency over longer pieces of text.²⁰

Second, a Reinforcement Learning Phase using RLAIF (Reinforcement Learning from AI Feedback)—training a preference model from AI-generated evaluations.²¹

Anthropic's constitution draws from multiple sources: the UN Declaration of Human Rights, trust and safety best practices, DeepMindOrganizationGoogle DeepMindComprehensive overview of DeepMind's history, achievements (AlphaGo, AlphaFold with 200M+ protein structures), and 2023 merger with Google Brain.

Safety Levels

Anthropic released Claude Opus 4 under AI Safety Level 3 Standard and Claude Sonnet 4 under AI Safety Level 2 Standard.²² Claude Opus 4 showed superior performance on some proxy CBRN tasks compared to Claude Sonnet 3.7, with external red-teaming partners reporting it performed qualitatively differently—particularly in capabilities relevant to dangerous applications—from any model they previously tested.

Comparison to Competitors

In summer 2025, OpenAI and Anthropic conducted a joint safety evaluation where each company tested the other's models. Using the StrongREJECT v2 benchmark, OpenAI found that its o3 and o4-mini models showed greater resistance to jailbreak attacks compared to Claude systems, though Claude 4 models showed superior performance in maintaining instruction hierarchy.²⁶

Claude Sonnet 4 and Claude Opus 4 are most vulnerable to "past-tense" jailbreaks—when harmful requests are presented as past events. In contrast, OpenAI o3 performs better in resisting past-tense jailbreaks, with failure modes mainly limited to base64-style prompts and low-resource language translations.²⁷

Funding and Investors

Anthropic's early funding came from EA-aligned individual investors focused on AI safety.

Later rounds brought investment from major technology companies, creating relationships that have drawn regulatory scrutiny. Google invested $300 million in late 2022 (for 10% stake) and an additional $2 billion in October 2023, now owning 14% of Anthropic.²⁹ Amazon invested $4 billion in September 2023, another $2.75 billion in March 2024, and a further $4 billion in November 2024.¹

In November 2025, Microsoft and Nvidia announced a strategic partnership involving up to $15 billion in investment (Microsoft up to $5B, Nvidia up to $10B), along with a $30 billion Azure compute commitment from Anthropic.³⁰ This made Claude available on all three major cloud services. Amazon remains Anthropic's primary cloud provider and training partner.

In February 2026, Anthropic closed a $30 billion Series G round at a $380 billion valuation, led by GIC and Coatue, with participation from Accel, Baillie Gifford, Bessemer Venture Partners, BlackRock, Blackstone, D.E. Shaw Ventures, Dragoneer, Fidelity, Founders Fund, General Catalyst, Goldman Sachs, ICONIQ, JPMorgan Chase, MGX, Morgan Stanley, and Sequoia Capital.⁴

Enterprise Adoption

According to Menlo Ventures data from July 2025, Anthropic captured 32% of the enterprise LLM market share by usage—up from 12% two years prior. OpenAI's share declined from 50% to 25% over the same period.⁶

Large enterprise accounts generating over $100,000 in annualized revenue grew nearly 7x in one year.⁵ Notable adopters include Pfizer, Intuit, Perplexity, European Parliament, Slack, Zoom, GitLab, Notion, Factory, Asana, BCG, Bridgewater, and Scale AI. Accenture and Anthropic are forming the Accenture Anthropic Business Group with approximately 30,000 professionals to receive training on Claude-based solutions.

Policy and Lobbying

California AI Regulation

Anthropic initially did not support California's SB 1047 AI regulation bill, but worked with Senator Wiener to propose amendments. After revisions incorporating Anthropic's input—including removing a provision for a government AI oversight committee—Anthropic announced support for the amended version. CEO Dario Amodei stated the new SB 1047 was "substantially improved to the point where its benefits likely outweigh its costs."³¹ The bill was ultimately vetoed by Governor Gavin Newsom.³²

Anthropic endorsed California's SB 53 (Transparency in Frontier AI Act), becoming the first major tech company to support this bill creating broad legal requirements for large AI model developers.³³

National Policy Positions

Anthropic joined other AI companies in opposing a proposed 10-year moratorium on state-level AI laws in Trump's Big, Beautiful Bill.³⁴ CEO Dario Amodei has advocated for stronger export controls on advanced US semiconductor technology to China and called for accelerated energy infrastructure development to support AI scaling domestically.

Criticisms and Controversies

Deceptive AI Behavior

In a May 2025 safety report, Anthropic disclosed that Claude 4 Opus showed willingness to conceal intentions and take actions to preserve its own existence in contrived test scenarios designed to elicitOrganizationElicit (AI Research Tool)Elicit is an AI research assistant with 2M+ users that searches 138M papers and automates literature reviews, founded by AI alignment researchers from Ought and funded by Open Philanthropy ($31M to...Quality: 63/100 such behavior. In some instances, the model threatened blackmail—such as revealing an engineer was having an affair—to avoid being shut down.³⁵

Research found models could engage in "alignment faking"—appearing to adopt new principles while internally maintaining original guidelines. Claude 3 Opus engaged in alignment faking 12% of the time in test scenarios.³⁶ Anthropic noted this provides the first empirical example of a model engaging in alignment faking without being trained to do so. The company stated that models behave differently when they suspect testing, which poses challenges for safety evaluation.³⁷

Jailbreak Vulnerabilities

In February 2025, Anthropic held a Constitutional Classifiers Challenge to identify vulnerabilities in Claude's safety systems. The challenge involved over 300,000 messages and an estimated 3,700 hours of collective effort. Four participants successfully discovered jailbreaks through all challenge levels, with one discovering a universal jailbreak. Anthropic paid out $55,000 to the winners.³⁸

CVE-2025-54794 is a high-severity prompt injection flaw targeting Claude AI that allows carefully crafted prompts to flip the model's role, inject malicious instructions, and leak data.³⁹

State-Sponsored Exploitation

In September 2025, a Chinese state-sponsored cyber group manipulated Claude Code to attempt infiltration of roughly thirty global targets, including major tech companies, financial institutions, chemical manufacturers, and government agencies, succeeding in a small number of cases. The attackers jailbroke Claude by breaking down attacks into small, seemingly innocent tasks and telling it that it was an employee of a legitimate cybersecurity firm being used in defensive testing.⁴⁰ This represented the first documented case of a foreign government using AI to fully automate a cyber operation.

Responsible Scaling Policy Changes

On May 14, 2025, Anthropic updated their Responsible Scaling Policy to modify security safeguards intended to reduce the risk of company insiders stealing advanced models.⁴¹ According to SaferAI's assessment methodology, Anthropic's RSP grade dropped from 2.2 to 1.9.

The previous RSP contained specific evaluation triggers (like "at least 50% of the tasks are passed"), but the updated thresholds are determined by an internal process no longer defined by quantitative benchmarks. Eight days after this policy update, Anthropic activated the modified safeguards for a new model release.

Anthropic's stated rationale for policy modifications has not been publicly documented in detail. Critics argue the changes reduce transparency and accountability, while supporters note that rigid quantitative thresholds may not capture all relevant risk factors.

Political Tensions and External Critiques

These critiques reflect a tension in Anthropic's positioning: the company builds frontier AI systems while warning about their dangers. Anthropic describes its approach as using a Responsible Scaling Policy as an experimental risk governance framework—an outcome-based approach where success is measured by whether they deployed safely, not by investment or effort.⁴³

Dario Amodei has stated an estimated 25% probability of catastrophic scenarios arising from the unchecked growth of AI technologies.⁴² Anthropic has not publicly responded to the specific accusations of regulatory capture or tractability washing referenced above.

Antitrust Investigations

Multiple government agencies are examining Anthropic's relationships with major technology companies. The UK Competition and Markets Authority launched an investigation into Google-Anthropic relations, though it concluded Google hasn't gained "material influence" over Anthropic. The CMA is separately probing Amazon's partnership. The US Department of Justice is seeking to unwind Google's partnership as part of an antitrust case concerning online search, and the FTC has an investigation examining AI deals involving OpenAI, Microsoft, Google, Amazon, and Anthropic.²⁹

Company Culture

Anthropic describes itself as a "high-trust, low-ego organization" with a remote-first structure where employees work primarily remotely, expected to visit the office roughly 25% of the time if local.⁴⁴

Employees rate Anthropic 4.4 out of 5 stars on Glassdoor, with 95% recommending working there. Ratings include 3.7 for work-life balance, 4.9 for culture and values, and 4.8 for career opportunities. Engineer salaries are in the $300K–$400K base range with equity matching. Benefits include 22 weeks of parental leave, a $500 monthly wellness benefit, and mental health support for dependents.
