Leaked 512,000-Line Claude Code CLI Source Code Sparks Anthropic Scrutiny Over Data Practices and IPO Future

Post date: April 3, 2026 · Discovered: April 17, 2026 · 3 posts, 5 comments

The core event is the alleged leak of the entire Claude Code CLI source code, estimated at 512,000 lines, reportedly exposed via a .map file found in an NPM registry.

Commenters focus heavily on this leak, with 'other_cat' pointing to the material found at github.com/instructkr/claw-code. Concerns expand to data monitoring, with 'BrikoX' comparing the situation to Microsoft Recall. Furthermore, 'other_cat' noted that the developers themselves are showing internal reliance, citing a claim that 100% of recent contributions to Claude Code came from the AI agent.

Beyond the code leak, skepticism clouds Anthropic's readiness for an IPO. 'plateee' sharply questions the financials, pointing to an 'insane gap between income, expenses, and profit.' The weight of opinion centers on Anthropic's opaque development and financial standing, using the code leak as immediate evidence of lax security.
