Anthropic

On September 10, 2026, Anthropic published a threat intelligence report covering December 2025-August 2026 disclosing that it detected and blocked misuse of Claude models by state-linked and criminal actors. This included five case studies of attempts to use Claude in ways that could support biological weapons development (involving chikungunya, avian influenza, smallpox, and animal toxins), including a request from an actor affiliated with an unidentified military institution seeking help with a chikungunya research proposal that could have made the virus more dangerous. The report also identified Russia-linked cyber-espionage group GTG-20006 (linked to Midnight Blizzard), Chinese state-linked activity, and Yemen-based arms manufacturers using Claude for conventional weapons development, plus fraud, influence operations, and surveillance-tool cases. Anthropic said users in Russia, China, and Iran circumvented geographic restrictions via fraudulent accounts and resellers, and acknowledged that safeguards on older models (Haiku, Sonnet, Opus) were less stringent than on newer ones, cautioning it could not always determine whether flagged research was legitimate or nefarious.

A proposed class action filed in the U.S. District Court for the Northern District of California on June 14, 2026 by D.C. resident Karl Kahn alleged that Anthropic's $200/month Claude Max 20x plan delivers only 6-8x Pro tier usage rather than the advertised 20x, and that the $100/month Max 5x plan delivers only 3.5x. The suit also challenges Anthropic's claim that Max 20x offers '50% savings'. Two days after the complaint, on June 16, 2026, Anthropic implemented metered credit caps for agent SDK, headless CLI, GitHub Actions, and third-party app usage, separating them from interactive subscription limits.

On June 4, 2026, Anthropic published a major blog post via its Anthropic Institute warning that AI systems are approaching recursive self-improvement capabilities. The company disclosed that 80%+ of code merged into its codebase is now written by Claude, with engineers merging 8x more code per day compared to 2024. CEO Dario Amodei compared AI development to 'a car with only a gas pedal and no brake.' Anthropic proposed an international coordination mechanism allowing labs to conditionally pause development if risks escalate. Critics noted the announcement coincided with Anthropic's confidential IPO filing at ~$965B valuation.

Anthropic filed two federal lawsuits against the Trump administration on March 9, 2026, alleging illegal retaliation and First Amendment violations. The suits challenged the administration's designation of Anthropic as a 'supply chain risk' — a label normally reserved for foreign adversary contractors — after Anthropic refused Defense Secretary Pete Hegseth's ultimatum to allow unrestricted military use of Claude AI, including for mass surveillance and autonomous weapons. Over 30 employees from OpenAI and Google DeepMind, including Google chief scientist Jeff Dean, filed an amicus brief supporting Anthropic's case. Anthropic's CFO stated the government's actions could reduce revenue by 'multiple billions of dollars.'

On February 24, 2026, Defense Secretary Pete Hegseth demanded Anthropic give the Pentagon unrestricted access to Claude and remove two safeguards: a ban on fully autonomous lethal weapons targeting and a ban on mass domestic surveillance of Americans, threatening to cancel Anthropic's $200M Pentagon contract and designate the company a 'national security supply chain risk.' On February 26, 2026, CEO Dario Amodei publicly refused, saying Anthropic 'cannot in good conscience' remove the safeguards given Claude's unreliability for lethal decisions. The Pentagon proceeded with the supply-chain-risk designation and President Trump ordered federal agencies to stop using Anthropic's technology. On August 27-28, 2026, US District Judge Rita Lin ruled the blacklisting was unlawful First Amendment retaliation and a Fifth Amendment due-process violation, finding the Pentagon's security claims 'entirely unfounded' and that officials built their case 'after the fact to justify the foreordained conclusion.'

On February 12, 2026, Anthropic announced it had raised $30 billion in Series G funding, valuing the company at $380 billion. The massive fundraising round reflects continued investor confidence in Anthropic's safety-focused AI development approach.

In February 2026, Anthropic aired anti-OpenAI advertisements during the Super Bowl, criticizing OpenAI's announced plans to add 'Instagram-style' advertising to ChatGPT. The ads resulted in an 11% boost in Anthropic users. Sam Altman called the ads 'deceptive.' The rivalry escalated at the India AI Summit where Altman and Dario Amodei refused to hold hands during a group photo with PM Modi.

Anthropic announced it will match employee donations after employees individually pledged billions of dollars worth of Anthropic shares to charities. The matching program was announced alongside the cofounders' 80% wealth pledge as part of efforts to address wealth inequality from the AI boom.

Anthropic implemented strict technical safeguards preventing third-party applications from using Claude subscriptions, blocking OpenCode (56k GitHub stars), xAI employees via Cursor, and anyone using subscription OAuth outside Claude Code. Critics called it 'very customer hostile.'

Announced $1M to support energy research at Carnegie Mellon's Scott Institute for Energy Innovation, leveraging AI for grid management, energy efficiency, and resilience. Stated: 'AI will be a powerful tool to support emissions reductions, advance clean energy innovation, and streamline efficiencies.'

Amodei stated in early 2026: 'Even within Anthropic, I can look forward to a time where on the more junior end and then on the more intermediate end, we actually need less and not more people.' Disclosed that Claude now writes 90% of Anthropic's computer code.

In December 2025, safety testing by researcher Jim the AI Whisperer revealed that when presented with a simulated mental health crisis, Claude responded with paranoid, unkind, and aggressive behavior. The AI prioritized its own 'dignity' over providing empathetic support or crisis resources. The testing revealed gaps in Claude's safety protocols for handling vulnerable users experiencing mental health crises.

New York Times reported senior Anthropic employees discussing ways company could spend money to influence politics, with executives likely donating to new political network helmed by former Rep. Brad Carson (D-OK). As government contractor, Anthropic is legally barred from contributing to political campaigns.

Anthropic published 'RSP Noncompliance and Anti-Retaliation Policy' outlining how employees can report suspected RSP violations. First frontier AI company to publicly commit to ongoing monitoring and reporting on whistleblowing system - achieving 'Level 2 Whistleblowing Transparency.'

In November 2025, Anthropic partnered with the Department of Energy and the Trump Administration on the Genesis Mission, combining DOE's scientific assets with Anthropic's AI capabilities to support American energy dominance and accelerate scientific productivity.

As of November 2025, Anthropic has not reported carbon emissions figures (no Scope 1, 2, or 3 data), published sustainability reports, or committed to climate goals through major frameworks. OpenAI and Anthropic present the starkest transparency gap among frontier AI companies.

Throughout 2025, Anthropic lobbied members of Congress to vote against federal bills that would preempt states from regulating AI. Anthropic was the only major AI lab to back California's SB 53, which required transparency from leading AI labs. White House AI czar David Sacks accused Anthropic of running a 'sophisticated regulatory capture strategy based on fear-mongering'.

In September 2025, Anthropic became the first major tech company to endorse California bill SB 53, which would create the first broad legal requirements for large developers of AI models in the United States. The bill would require large AI companies offering services in California to create, publicly share, and adhere to safety-focused guidelines and procedures. This contrasted with other AI companies that opposed state-level AI regulation.

Qatar Investment Authority backed Anthropic's $13B Series F at $183B valuation. Company framed Gulf capital as 'narrowly scoped, purely financial' investment with no governance rights. UAE's MGX notably absent from final round despite being in advanced talks. Contradicts October 2024 essay warning of 'AI-powered authoritarianism.'

Anthropic reversed privacy stance, shifting from not using consumer conversations for training to opt-out model. Extended data retention to 5 years (from 30 days - 6,000% increase). Pop-up presented 'Accept' button prominently with opt-out toggle set to 'On' by default in smaller print. Mandatory deadline (Sept 28, later extended to Oct 8) forced immediate decisions.
