CFOs Now Lead AI Spending and Trust Oversight, Survey Shows

Finance chiefs are finding their job descriptions rewritten in real time as artificial intelligence reshapes enterprise operations. More than half now lead decisions about AI and technology capital allocation across their organizations—a responsibility that barely existed on finance teams' radar three years ago.

A Deloitte survey of 1,434 finance leaders across 26 countries, released September 8, reveals the speed and scope of this shift. When asked about responsibilities outside traditional finance functions, 54% of respondents said they now lead cross-enterprise AI and technology capital allocation. Nearly as many—48%—oversee AI trust initiatives, ensuring outputs are reliable, accurate, and explainable. An equal percentage manage AI and technology spending controls.

The timeline tells the story: More than two-thirds of finance leaders who have taken on these new duties did so within the last three years, according to the report.

Why it matters

This expansion of the CFO mandate reflects a fundamental challenge organizations face with AI: the technology cuts across every function, generates costs that are difficult to predict, and carries risks that demand C-suite attention. Finance leaders possess the cross-functional visibility and resource allocation authority to coordinate enterprise-wide AI strategy—making them the logical choice to own these decisions even as they stretch beyond traditional financial planning and analysis.

Cost management becomes more complex

The survey data suggests finance teams are bracing for turbulence. Six in ten respondents expect AI costs and complexity to increase substantially in 2027. Only 35% plan to maintain their current cost management practices, signaling that most recognize existing approaches won't suffice.

The report's authors note that finance leaders anticipating cost increases are more likely to work at organizations further along in their AI maturity. This correlation suggests that as companies deploy AI more broadly, the associated expenses and management challenges multiply.

Finance teams will need to adopt what the survey describes as "more sophisticated AI cost management practices" in the coming year. The specifics of those practices remain to be defined, but the pressure is clear: 43% of respondents are prioritizing AI and advanced technology to automate operations in the 2027 fiscal year.

The expanding finance mandate

The Deloitte report frames these findings as evidence of how rapidly finance leaders' mandates are growing. The survey captures a profession in transition, with CFOs absorbing strategic technology responsibilities that didn't exist in their job descriptions until recently.

For finance leaders comparing their own situations to peers, the data offers both validation and a benchmark. The shift toward technology oversight isn't happening in isolation—it's a pattern playing out across industries and geographies as AI moves from pilot projects to production systems.

The findings were first reported by CFO Brew, which noted the survey provides a snapshot of how 1,434 finance leaders across 26 countries are navigating these changes.
