Coinbase's Head of Platform, Rob Witoff, revealed that 95% to 100% of the exchange's code is now produced by artificial intelligence (AI). This marks a significant increase from 40% recorded in February 2026.

Witoff explained that Coinbase engineers typically operate five to ten AI agents simultaneously, achieving the equivalent productivity of around 1,200 human workers. His projection indicates that by 2030, the output from AI agents could match the output of approximately 100,000 employees.

Rapid Adoption of AI in Development

During an exclusive interview, Witoff emphasized the extent to which AI has become integral to daily operations at Coinbase. He noted, “Effectively, 100% of our employees are using AI on a daily basis here.” He further clarified that the vast majority of code, estimated to be between 95% and 100%, relies on large language models (LLMs), which underpin tools like ChatGPT.

The rapid escalation in AI involvement is striking; in just five months, the share of AI-generated code doubled. Witoff mentioned a structured approach to AI integration: while core cryptography still needs significant human oversight, the prototyping phase is fully automated, and core system management falls between these extremes. This tiering is vital for safeguarding billions in customer assets, as even a minor error in code can lead to security vulnerabilities.

Cultural Shift in Tech Employment

The dramatic shift at Coinbase comes alongside broader trends in the tech sector, where many companies are increasingly employing AI to streamline workflows. Joining forces with notable entities like Ripple and Visa, Coinbase is now a member of the x402 Foundation, which aims to standardize AI agent payments.

Critics argue that the metrics surrounding AI-generated code can be misleading. The term “written with the help of AI” can range from minor autocomplete functions to complete autonomous code submissions. Witoff’s range of 95% to 100% captures this spectrum, indicating a growing reliance on AI across various stages of software development.

Despite the debate over metrics, the overall trend is clear: Coinbase, which previously reported only 40% of its code being AI-generated, now finds it challenging to identify any code that has not been influenced by AI.
