Companies Are Scaling AI on Data They Don't Trust, New Study Finds
Nearly half of 350+ Finance and IT Executives surveyed made major business decisions on faulty data in the past year; those burned by bad data use the most AI tools
With AI spending forecasted to surpass
The consequences are significant:
- Nearly three in four executives (72%) say bad data cost their organization
$500,000 or more, with more than one-third (37%) reporting damages over$1 million . - Downstream impacts include: more than four in 10 (44%) delayed reporting and closing, while over one-third cite lost revenue opportunities (41%), a lack of trust in automated insights (38%), and compliance issues (35%).
Despite these risks, companies are not slowing down. Executives who have made decisions on bad data are four times more likely to use ten or more AI tools than their peers. At the same time, confidence is fragile—an overwhelming 95% of these executives report concerns about AI-related risks, including flawed decisions (37%) and one in five (20%) cites financial misreporting.
"Nearly half of executives admit they've made decisions on bad data, yet AI adoption continues to accelerate. Unless companies have data they can trust, AI will only accelerate and amplify bad decisions," said
Emerging Blind Spot: High Confidence, Low Trust in the Age of AI
As boards demand faster execution and measurable
The issue is structural. Today, just 19% pull the majority of their AI inputs from a single, centralized enterprise system. Further, only half have established a consistent source of truth, implemented data quality rules, or automated reconciliation across systems. As a result, disconnected systems and lack of integration (32%) were cited among the top barriers to effective governance. AI is often deployed on shaky data - amplifying errors rather than eliminating them.
Speed vs. Structure: Why AI Fluency Isn't Enough
The data accuracy challenges become more visible where technical fluency outpaces institutional knowledge. While AI enables faster analysis, it cannot replace the business context required to recognize when data is incomplete or misleading.
Rising leaders (ages 25–44) are heavier AI users—over four in five (82%) use three or more AI tools for decision-making, compared to 69% of more experienced peers. Yet they are also more exposed to risk: over half (51%) report making a material decision based on faulty data, versus 39% of older leaders.
The consequences are more severe as well. Younger executives are over four times more likely to report significant financial or compliance impacts (17% vs. 4% among seasoned peers), and twice as likely to cite a loss of trust in AI outputs (44% vs. 22%).
This highlights a critical gap: AI proficiency alone is not enough. Without strong governance and business context, the leaders most equipped to use these tools are also the most vulnerable to their risks.
A Shared Challenge Viewed Differently
While Finance and IT are aligned in recognizing the importance of data governance, and most (89%) executives claim Finance and IT are aligned, 85% of CIOs believe they lead data governance, while 78% of CFOs claim the lead. They also have a different perspective on data governance challenges: Finance prioritizes accuracy, context, and accountability, and IT focuses on enablement, scalability, and execution. Because of this disconnect, nearly 1 in 3 CFOs (32%) cites "lack of data ownership" as a key barrier to success.
However, when Finance and IT come together, the impact is significant: organizations that achieve complete alignment between Finance and IT are 5.5x more likely to report complete trust in their data. Closing this gap is what turns governance from a program into a true foundation for AI-driven decision-making.
"Every generation of finance leaders has had to earn trust in the numbers before they could act on them. What's different today is that AI has compressed that timeline dramatically, and the margin for error has shrunk with it," said
