At Code with Claude, a Mercado Libre executive disclosed the company's goal of achieving 90% autonomous coding by Q3 2026 across its 23,000-engineer workforce. This is the most aggressive AI coding adoption target publicly stated by any enterprise at this scale. The announcement reflects a broader theme at the event: executives and managers are increasingly writing code themselves, with the time investment per feature dropping enough that non-engineers can meaningfully participate in development.
