Crypto News
Coinbase CEO Brian Armstrong disclosed that AI now writes between 95% and 100% of the exchange's code, a sharp jump from roughly 40% reported as recently as February. The disclosure comes against the backdrop of roughly 700 layoffs at the publicly traded US exchange, framing the AI ramp as a deliberate headcount substitution rather than a productivity sidecar.
Head of Platform Rob Witoff added that nearly every Coinbase employee now uses AI daily, and that engineers routinely run multiple AI agents in parallel on routine coding and review tasks. The framing is unusually direct from a publicly traded US company: management is naming AI as the reason the headcount math changed.
Why it matters
A publicly traded US exchange publicly tying a near-fivefold jump in AI-written code to a layoff round of that size is a rare, specific data point in the AI-productivity debate. Coinbase is not a stealth startup running vibe-coded demos; it ships regulated financial software to millions of users. The implication is that AI coding assistants have crossed a threshold inside at least one production-scale engineering org.
Market impact
For labor, the read is uncomfortable: if 95% of code can be AI-written five months after only 40% could be, the replacement curve for routine engineering work is steeper than most 2026 corporate forecasts assumed. For crypto specifically, the second-order read is competition, with Coinbase leveraging the same AI leverage every other exchange, custody shop, and on-chain analytics firm is now racing to deploy.
