Coinbase has essentially replaced most of its engineering workforce with AI, at least on paper. The crypto exchange now reports that between 95% and 100% of its code is either written by or assisted by large language models, a figure that sat at just 40% as recently as February 2026.
From 5.7% to nearly everything
The progression tells the real story. In the first quarter of 2025, AI-generated code accounted for just 5.7% of Coinbase’s total codebase. By the fourth quarter of 2025, that share had crossed 50%. By the first quarter of 2026, it had reached roughly 80%. Now, the company says it is approaching full AI assistance across the board.
Every employee at Coinbase reportedly uses AI tools on a daily basis. The efficiency gain the company is pointing to is significant. Coinbase says its current AI deployment is equivalent to the output of approximately 1,200 human developers. The longer-term ambition is more striking: the company believes it could scale that capacity to match the output of 100,000 human developers by 2030.
