90 percent of developers use ai coding agents and only 29 percent trust their accuracy. jetbrains' 2026 ecosystem survey, out september 15, found 66 percent spend more time fixing almost-correct code.
adoption ran far ahead of trust.
Context
JetBrains' research blog post, listed August 18, 2026, says that as of May to July 2026, 90 percent of professional developers were using AI coding agents at work at least weekly, with 68 percent using them daily. It draws on the Developer Ecosystem Survey 2026 with more than 15,000 professional developers, statistically reweighted, and the usage is self-reported and not measured. The post also reports Claude Code at 39 percent adoption and Codex at 16 percent, and says more findings will follow.
The 90 percent is weekly use of agents among the surveyed professional developers, and the post is dated August 18, not September 15. The 29 percent trust and 66 percent almost-correct figures were not found in that post, and a secondary snippet ties 29 percent to a different JetBrains release in April 2026, so those two figures are unverified against this survey release and may belong to another survey. Adoption ran far ahead of trust is the author's take.
