A survey of a hundred and fifty-two CEOs found the proof gap, and put it at forty-two points.

More than half call linking AI to the bottom line their barrier. Only fourteen percent have defined it.

The earnings prints were the symptom. BCG measured the disease. In a survey of a hundred and fifty-two chief executives at companies above five hundred million dollars in revenue, more than half named linking AI to the bottom line as their central barrier, while only fourteen percent said they had clearly defined that impact across all their AI initiatives. The distance is forty-two points, and it is the whole story: nearly nine in ten feel AI is delivering benefits somewhere, and almost none can prove where.

HCLTech's own research put the same hole in starker relief, ninety percent reporting workflow transformation against eighteen percent reporting revenue impact, a seventy-two point version of the identical absence. The value is felt across the organization and provable on none of the income statement, because the artifact that would demonstrate it was never built.

There is a caution worth keeping. The survey is BCG's own, and the firm sells the fix for the gap it is measuring. But the diagnosis holds, because the market spent the same week acting on it: it marked down the companies that could not show the return and left the number as the reason.
