What it claims
Grant Thornton’s 2026 AI Impact Survey, in its banking sector cut, reports that banks are more likely than any other industry surveyed to say their AI controls are untested, and that only about 18% of banking respondents say they are fully confident in their AI controls. The survey is positioned as practitioner evidence that AI adoption in banking is running ahead of the maturity of the controls and assurance wrapped around it.
The finding sits alongside the broader 2026 practitioner-survey picture (Cambridge CCAF, ProSight CRO Outlook, Informatica CDO Insights, McKinsey) that AI adoption is outpacing governance maturity, with data quality, staff capability and immature risk frameworks as the binding constraints rather than the technology itself.

What’s speculative vs. asserted
- Asserted (by the source): ~18% of banking respondents are fully confident in their AI controls; banks are the industry most likely to report untested controls.
- Speculative / not confirmed this run: the survey sample size, methodology, geographic mix, and exact publication date; whether “fully confident” maps precisely to the “pass an independent review within 90 days” framing used elsewhere in the wiki.
Topics this feeds
Open questions raised
- The survey’s sample, methodology and exact publication date.
- Whether the ~18% “fully confident in AI controls” figure is the same underlying data point cited elsewhere in the wiki against the “pass an independent review within 90 days” framing, or an independent corroborating measure.
Ingestion note
Search-derived stub. Identified and summarised via WebSearch (Grant Thornton banking insights page surfaced in results). The full report was not retrieved or parsed this run, and the exact publication date is not pinned — the source-date is approximated to May 2026 and flagged for confirmation. This page lets the ~18% “fully confident in AI controls” figure — previously cited on the AI Governance Maturity Gap topic without a dedicated S-tag for this specific survey — be attributed to a named source.
