Anthropic says Claude now writes most of the company’s code

Anthropic chief financial officer Krishna Rao said the company’s artificial intelligence model Claude now generates more than 90 percent of Anthropic’s internal code, underscoring how rapidly AI systems are reshaping software development and corporate operations. Rao made the comments during his first public podcast appearance on the “Invest Like the Best” program hosted by Patrick O'Shaughnessy.

Rao explained that much of the code behind Claude Code is also produced by the same system, creating a recursive development cycle in which the model contributes to building future versions of itself. He said this internal use of computing resources is one reason Anthropic dedicates part of its infrastructure capacity to internal operations rather than assigning all available power to paying customers.

The executive described Anthropic’s finance division as a testing ground for large scale AI deployment. According to Rao, Claude now assists in generating financial statements and preparing monthly financial reviews that are already “90 to 95 percent” complete before human staff conduct oversight and verification. He said teams increasingly rely on “fleets of agents” capable of handling multiple parallel assignments across departments.

Rao argued that the shift is transforming knowledge workers into managers of AI systems rather than employees focused mainly on manual execution. He described Claude as a “virtual collaborator” that reduces time spent gathering information and increases time available for strategic decision making. The changes extend beyond engineering teams and now affect finance, operations and internal planning throughout the company.

The interview also revealed the scale of Anthropic’s financial growth. Rao said the company entered 2026 with annualized revenue near $9 billion before surpassing a $30 billion annualized pace by the end of the first quarter. He attributed the surge directly to improvements in model intelligence that expanded enterprise demand and opened new commercial applications for generative AI systems.

Anthropic’s coding platform Claude Code reportedly reached $1 billion in annualized revenue within six months of its public launch in 2025. Rao added that enterprise subscriptions for the product have quadrupled since the start of 2026 as businesses accelerate adoption of AI assisted programming tools.

Rao framed the company’s strategy around what he called the “returns to frontier intelligence,” arguing that every major improvement in AI capability increases the size of the enterprise software market. He said businesses are responding because newer generations of models allow companies to complete more work faster and with greater operational efficiency.
