Negotiated Fable 5 and Mythos 5 restoration with Commerce Secretary Lutnick; chose direct talks over a legal challenge; models restored July 1 after a 19-day suspension

Anthropic restored Claude Fable 5 globally on July 1, 19 days after Commerce Secretary Howard Lutnick ordered its suspension. The company built a new safety classifier, developed with Amazon, Microsoft, and Google, that blocks the cited jailbreak in more than 99 percent of cases. Lutnick confirmed the government spent two weeks working with Anthropic to ensure 'alignment with the U.S. Government.'

Leading Anthropic's push to make cheaper models do flagship-level work

On July 1, 2026, anyone who opened Claude got a smarter model without lifting a finger. Anthropic made Claude Sonnet 5 the default for every Free and Pro user worldwide, retiring Sonnet 4.6.

Company in active dispute with US government over export control suspension of Fable 5 and Mythos 5; models remain offline

Trump signed a voluntary framework on June 2 asking frontier labs to share their newest models with federal agencies for up to 30 days before release. Within ten days, the government had gone further. A June 12 export control directive forced Anthropic to kill worldwide access to Fable 5 and Mythos 5, its two newest models, after the government said it had found a jailbreak in the more capable one.

OpenAI's Codex can now see and click inside Windows applications, a capability Anthropic's Claude has offered since October 2024. Microsoft joined them at Build 2026 in early June, launching its own Windows Agent Framework as open-source software and introducing Scout, an always-on background agent for Microsoft 365.

Four weeks after unveiling its Wall Street agents, Anthropic filed a confidential S-1 with the SEC on June 1, 2026, backed by a $65 billion funding round at a $965 billion valuation. JPMorgan Chase—the bank whose CEO Jamie Dimon co-headlined the May 5 product launch—is one of three lead underwriters.

Running Anthropic; aligned with Clark's capability forecasts

Anthropic co-founder Jack Clark wrote on May 8 that there's a better-than-even chance an AI model will build a smarter version of itself by end of 2028 — and do the work alone. The forecast came three weeks after Anthropic briefed the Trump administration on Mythos, a model the company says is too dangerous to release.

Leading Anthropic's response to Mythos disclosure while managing ongoing Pentagon litigation

An AI model that can find software flaws no human has caught in nearly three decades has triggered a coordinated response from central banks across the Western world. Anthropic's Claude Mythos Preview discovered thousands of previously unknown vulnerabilities in every major operating system and web browser, prompting Treasury and Federal Reserve to summon Wall Street executives to Washington on April 8. By April 11, the Bank of England, Bank of Canada, and their respective financial regulators had convened or scheduled their own emergency sessions with banks.

Leading Anthropic through IPO preparation

Anthropic offered employees up to $6 billion in liquidity through a tender offer at a $350 billion valuation — the same price as its February fundraising round. Employees mostly said no. The sale completed in early April well below its target because staff chose to hold their shares, betting that the company's planned initial public offering (IPO) later in 2026 will deliver a higher price.

Negotiating with US government over Mythos access; arrived at White House on April 17 for talks with Chief of Staff Susie Wiles

Anthropic built an AI model so capable at finding software vulnerabilities that it decided not to sell it. Claude Mythos Preview, announced April 7, autonomously discovered thousands of previously unknown security flaws in every major OS and web browser — including a remote crash bug in OpenBSD undetected since 1999. Rather than offering the model commercially, Anthropic restricted access to 12 major technology companies through Project Glasswing, backed by $100 million in usage credits.

Leading company through federal blacklisting; six-month phaseout period underway

For decades, the United States military chose its weapons contractors and they complied, but artificial intelligence changed that. On March 3, OpenAI and the Pentagon amended a freshly signed AI contract to ban domestic surveillance of Americans—a concession the Pentagon had refused Anthropic, triggering the company's blacklist from all federal agencies.

Leading federal lawsuits against Pentagon over supply chain designation

Anthropic's Claude became the first commercial AI model deployed on classified U.S. military networks in late 2024. Sixteen months later, the Defense Department designated Anthropic a "supply chain risk"—a label historically reserved for foreign adversaries—for refusing to permit Claude's use for mass surveillance of Americans or fully autonomous weapons.

Leading Anthropic's expansion into enterprise tooling

An estimated 220 billion lines of COBOL code still run in production every day, processing 95% of ATM transactions and roughly $3 trillion in daily commerce. For decades, understanding and modernizing that code has required large teams of specialized consultants working for months or years. On February 23, Anthropic published a playbook showing how Claude Code can automate these labor-intensive tasks—mapping dependencies, documenting workflows, identifying risks across thousands of files.

It's the most aggressive timeline yet from a major tech executive, and it comes as AI coding assistants already generate 46% of code at companies using GitHub Copilot.
