Only 22% of organisations have successfully scaled AI across multiple business units or adopted an AI-first approach according to a survey by Gartner, Inc.

Roughly 11% of organisations are entirely unaware of what their function spent on AI in 2025.

A Gartner survey from January-April 2026 of 1,303 respondents from organisations with enterprise-wide annual revenue of at least $50 million in fiscal year 2025 found that, despite this lack of success, investment in AI continues to accelerate.

Eighty-five percent of functional leaders plan to increase spending in 2026 after dedicating an average of 12% of their functional budgets to AI in 2025.

“This lack of financial visibility heightens risk as spending accelerates,” said Tina Nunno, Distinguished Vice President & Gartner Fellow. “Without disciplined measurement tied directly to business outcomes, organisations risk wasted resources and unmet expectations.”

High performers – companies that constantly track ROI of AI initiatives, treat AI as a portfolio of value and regularly assess project performance and reallocate or discontinue underperforming initiatives – reported positive returns in 81% of their AI initiatives, while low performers reported they did not know the rate of return for 29% of AI initiatives.

Furthermore, most functions are prioritising productivity gains over bold transformation or new revenue streams.

Productivity was a key target outcome for 75% of functional leaders, and it commands approximately 30% of functional AI spend on average, nearly twice the percentage of the next highest objective.

“Functional leaders who track every dollar spent by outcome category, such as productivity, revenue growth, risk mitigation, or innovation, are best positioned to defend investments and reallocate quickly if their projects underperform,” said Nunno.

“Without disciplined measurement tied directly to business objectives, organisations open themselves up to misallocation and missed opportunities as scrutiny intensifies.”

Popular AI Use Cases Rarely Deliver the Highest Returns

The most widely pursued AI use cases are rarely the ones delivering the highest positive returns. Functional leaders are frequently falling into the trap of prioritising “popular” or heavily hyped AI applications over those that generate tangible value.

When contrasting the top three use cases pursued with AI versus the top three use cases with the largest proportion of leaders reporting positive returns, a clear disconnect emerges for IT.

Cybersecurity threat detection and response (54%), IT service desk automation (54%) and automated code generation and refactoring (44%) were all identified as the most frequently pursued AI use cases by C-suite leaders.

However, intelligent IT asset and cost optimisation (40%), synthetic data generation (28%) and automated code generation and refactoring (23%) were identified as the top three AI use cases with positive returns.

“Organisations are seeing the greatest quantifiable value from less common, strategically selected use cases that are closely aligned to their unique business needs,” said Nunno.

“CEOs and CIOs must pinpoint which AI use cases truly drive positive financial returns, so they can set clear, effective targets for every function and leader.”
