Enterprise generative AI spending is rising fast even as returns remain uneven, according to McKinsey research summarized in its analysis of generative AI economics. Companies reported an average return of 3.70 dollars for every 1 dollar invested in generative AI, with the financial services sector leading all industries at a 4.2 times return.

Spending growth has been steep. Generative AI spend reached 37 billion dollars in 2025, up from 11.5 billion dollars in 2024, and 92 percent of companies said they plan to increase AI investment over the next three years. About 78 percent of organizations now use AI in at least one business function.

The ROI picture is mixed below the headline figures. Just 39 percent of organizations reported earnings impact at the enterprise level, and only 19 percent of executives said generative AI drove revenue increases above 5 percent, while 36 percent reported no revenue change from current implementations. Only about 1 percent of business leaders described their generative AI rollouts as fully mature.

McKinsey identified workflow redesign as the single strongest driver of return. High performers tended to set growth and innovation goals beyond simple efficiency, and most of them redesigned core workflows around AI rather than layering tools onto existing processes. The findings suggest that the gap between AI adoption and measurable financial impact often comes down to how deeply companies rebuild their operations around the technology.
