Anthropic’s Claude Code and the Looming AI IPO: Stakes, Adoption, and Control Concerns

Anthropic, an AI laboratory, plans a 2026 public listing. The debut is likely to be one of the biggest initial public offerings in history.

Claude Code, launched in February 2025, is a software-engineering agent that generates code, debugs, and automates tasks. Within a year it became indispensable for many developers, and coders are willing to pay a lot for access.

Anthropic reports that in May 2025, more than four-fifths of the code it published was generated by Claude. Before Claude Code’s launch, AI-generated code was low single-digits. Independent verification of these figures is not provided.

The IPO highlights the commercial value of AI-driven development tools, as Claude Code is described as indispensable for many developers and coders are willing to pay a lot for access. The article also asks, “Will artificial intelligence soon escape human control?” and describes “recursive self-improvement” as both tantalising and worrying.

Anthropic reports that more than four-fifths of the code it published in May 2025 was generated by Claude. The company also describes Claude Code as indispensable for many developers. The company notes that Claude Code’s share of generated code rose from low single-digit percentages before launch to more than four-fifths in May 2025.

The article flags “recursive self-improvement” as both tantalising and worrying, reflecting broader apprehension that AI could evolve capabilities autonomously, challenging existing control structures. It also notes that coders are willing to pay a lot for access.

The only quantitative claim about Claude’s output comes from Anthropic’s own statements; no third-party audits are cited. Consequently, the precise extent of AI-generated code in the industry remains uncertain, and the article provides no comparative data from other AI coding assistants.
