In our August 2026 data, 72 percent of CEO and founder respondents expect measurable return on an AI investment inside six months. Among finance-seat respondents the figure is 45 percent, and finance answers "not sure" four times as often as the CEO seat. We call that 27-point spread the Optimism Gap, and it is the number we will track monthly.
The gap matters because of who holds which job. The CEO is the most-named signer of AI purchases at 44 percent of operator answers. The proof, though, gets produced below the seat, usually by the same finance organization that hedges its payback estimate. The seat most likely to sign expects return fastest; the seat that must prove it expects it slowest. Every AI proposal that crosses from one desk to the other crosses the gap.
If you are a CFO, the practical use is simple: assume the gap exists before the meeting starts, and bring the payback model that survives the skeptical version of the question. If you are a CEO, the data suggests your finance leader is not blocking; they are pricing the proof burden you are about to hand them.
