Coinbase says 95% to 100% of its code is now AI-assisted, up from 40% in February

What happened

Coinbase announced 95-100% of its code is now AI-assisted — up from 40% in February 2026. Rob Witoff, Head of Platform, stated AI agents perform work equivalent to approximately 1,200 human developers.

Context and impact

Coinbase laid off 14% of employees (~700 people) in May 2026. The case illustrates how rapidly the ratio of human to AI work is shifting in software development and the growing correlation between AI adoption and layoffs.

Details

• 95-100% of code AI-assisted (vs. 40% in February 2026)
• Engineers routinely run 5-10 AI agents simultaneously
• AI equivalent of ~1,200 employees today; potentially 100,000 by 2030
• Cryptography and security-sensitive code: still human oversight line by line
• Context: 700 layoffs in May 2026 + rapid growth in AI coding adoption
