What should I do next in practice?
Several claims from public discussion—including specific future model names, a $65B funding round, and a 76% success rate metric—could not be independently verified and remain unconfirmed.
May 22, 2025: The product reached general availability (GA), with support for background tasks via GitHub Actions and native integrations for VS Code and JetBrains IDEs .
October 20, 2025: Claude Code expanded to the web. A research preview allowed Pro and Max subscribers to assign coding tasks that run on Anthropic-managed cloud infrastructure directly from a browser or the iOS app .
December 2025: Anthropic acquired Bun, the JavaScript runtime, to strengthen the infrastructure underpinning Claude Code’s rapid scaling .
February 2026: A “Remote Control” synchronization layer was introduced, allowing developers to monitor and manage local CLI sessions from smartphones and tablets .
March 2026: A dedicated web version launched, enabling users to create and manage multiple AI coding agents from a browser. Computer-use capabilities were also integrated for Pro and Max users, allowing Claude to operate dev tools and navigate screens autonomously .
June 2026: Interactive apps were added to the Claude mobile experience for iOS and Android, further blurring the line between coding and general productivity .
Revenue Growth and Market Impact
Claude Code’s revenue ramp is the fastest of any product in Anthropic’s history and notably rapid even within the broader AI market .
November 2025: Just six months after general availability, Claude Code surpassed $1 billion in annualized run-rate revenue .
February 2026: The product’s annualized revenue reached $2.5 billion, a figure that had more than doubled since the start of 2026 . At this point, business subscriptions had quadrupled in Q1 2026 .
By Mid-2026: Claude Code was authoring an estimated 4% of all public GitHub commits, with daily commit volume up approximately 200% over the eight weeks ending in mid-May 2026 .
This revenue stream drove Anthropic’s overall company run-rate from $14 billion in February 2026 to $30 billion in April 2026 and $47 billion in May 2026, according to Sacra estimates and company disclosures .
Which Companies Are Using Claude Code?
Enterprise adoption has been a critical factor. The product is now deployed in production across several Fortune 500 engineering organizations.
Confirmed enterprise customers include Netflix, Spotify, KPMG, Salesforce, Uber, L’Oréal, Accenture, and Snowflake. The KPMG partnership is particularly deep: in May 2026, the firm formed a global alliance with Anthropic, embedding “KPMG Digital Gateway Powered by Claude” into its client delivery platform and providing access to its entire global workforce of 276,000+ employees .
Eight of the Fortune 10 are active Claude customers overall, and Claude Code has captured over 50% of the AI coding market, competing directly against GitHub Copilot, Cursor, and Devin .
Anthropic’s Dogfooding: 80% of Code Written by Claude
One of the most striking internal metrics is how much Anthropic relies on its own tool. As of May 2026, more than 80% of the code merged into Anthropic’s production codebase was written by Claude. Before the Claude Code launch in February 2025, that figure was in the low single digits. Anthropic engineers are now shipping roughly eight times more code per day than they did in 2024 .
Funding, Valuation, and IPO
The product’s growth has paralleled a dramatic increase in the valuation of Anthropic as a whole:
February 2026: Anthropic closed a $30 billion Series G funding round at a $380 billion post-money valuation .
June 1, 2026: The company filed confidentially for an initial public offering, shortly after its run-rate surged to $47 billion .
Limits of Current Verification
While the above points are supported by official announcements and credible reporting, several widely circulated claims could not be confirmed from available sources:
Specific features like “auto mode” and “worktrees” unveiled at a “Code with Claude” conference
A 76% success rate on the hardest coding tasks, or a jump of 50 percentage points in six months
The launch of models called “Claude Fable 5” and “Claude Mythos 5”
A pricing shift to usage-based billing as the specific cause of the $30B run-rate milestone
The existence of a $65 billion Series H funding round at a $965 billion valuation
A named, focused effort to train models specifically for design quality and security review
In the absence of direct verification, these items remain unconfirmed. The story of Claude Code's first year is still best told through the milestones that are publicly documented, and those milestones alone are enough to signal a product with very intense product-market fit .
