DX's Q2 2026 report analyzing AI impact across 500+ engineering teams reveals that over 50% of code is now AI-generated (up from 34% in Q1), but the picture is mixed. While developers save 4–6 hours per week, the Developer Experience Index dropped, PR sizes nearly doubled, and change confidence declined 6.1% even as code maintainability improved. AI spend surged from ~$1.5K to ~$44K per quarter at the median, yet the innovation ratio remained flat — meaning saved time isn't converting into new feature work. Engineering leaders are urged to move beyond velocity metrics and focus on downstream ROI, quality, and resolving systemic bottlenecks.
