Finance chiefs in Pigment's CFO Index found usage-priced AI costing more than they expected
Pigment's Q3 2026 CFO Index found 83% of respondents saw consumption-based AI costs come in above expectations. Budget owners should expect central sign-off and milestone gates, though CloudZero's survey has 87% still planning to spend more.

Budget owners: tranches tied to milestones and measurable return. Departments: less freedom to sign up for tools alone. Usage-priced vendors: likeliest line item to be capped. Uber: spent its whole 2026 AI budget by April. Amazon: spending caps. Cisco: curbs on non-essential AI tools.

What happened
- U.S. Bank's September 2026 survey found 51% of US finance leaders said their AI spending over the previous year exceeded budget.
- Reuters reported in June 2026 that Amazon and other companies had put AI spending caps in place.
- Companies are moving to stage-gate funding, under which a project gets its money in installments and each installment depends on the project reaching a set milestone.
Why it matters
- decision Budget owners now have to attach a milestone and a measured return to each tranche request, because finance is insisting on return on investment before it approves more spend.
- constraint Departments lose the option of signing up for AI tools on their own, so a team that wants a new tool needs central sign-off first.
- contradiction Bloomberg describes finance executives cutting AI spending, while CloudZero's respondents mostly plan increases; the sources disagree on the direction of total spend.
- exposure AI vendors on usage pricing are exposed, since the article's assessment is that the model makes their product the line item a CFO is most likely to cap.
Under usage-based token pricing the vendor charges for how much the models actually process [8], so the invoice moves with volume and a budget set before volume is known has nothing fixed to hold against. That is our inference, and Uber's year fits it: a budget that was gone about a third of the way through 2026 [17], spent at that pace to December, implies full-year spend near three times plan [22]. Usage rarely holds a straight line, so the multiple is only an illustration.
The surveys do not ask the same question. Pigment asked whether consumption-based costs beat expectations [1], and U.S. Bank asked whether spending beat budget [2]. The two figures sit 32 points apart [14], and 49% of U.S. Bank's respondents did not report an overrun [15]. We'd guess a bill can miss a forecast and still fit inside a budget that carried slack. The article does not give sample sizes or say how respondents were chosen.
CloudZero's FY2027 survey puts two answers side by side. 87% of its finance leaders plan to raise AI budgets for the coming fiscal year [11], and 61% admit current spending exceeds what outcomes can justify [12]. If the same respondents answered both, as the article describes, at least 48% are in both groups (87 plus 61, minus 100) [16]. Elsewhere the sentiment is no colder: Pigment's respondents rated their confidence in AI's value at 8.2 out of 10 on average [9], and 69% of U.S. Bank's reported commercial benefits [10].
We think the control being installed, for now, gates allocation and leaves total spend in place. Mavvrik found that 25% of firms delayed or canceled AI projects because of unexpected costs [4], and Cisco has moved to curb non-essential AI tools [18]. The article's own suggestion is that money will flow to a smaller set of proven tools while experiments get squeezed out [19].
The counter-thesis is that budget plans are not binding. CloudZero's 87% is stated intent, and the same finance leaders whose bills already ran over forecast may revise it once the first tranche is withheld.
The thesis fails if forecasting improves. The article's marker is the surprise rate: if Pigment's 83% stays high into next year, the Uber, Amazon and Cisco caps could stop looking like outliers [20]. Deloitte's September 2026 research found that 60% of finance leaders expect AI costs and complexity to rise substantially through 2027 [3].
What to watch
- Whether the share of firms reporting AI costs above expectation in Pigment's next index stays near 83% or falls as forecasting improves.
- Whether spending caps like those at Uber, Amazon and Cisco spread into the standard policies of other companies.
- Whether the 87% of CloudZero respondents planning higher FY2027 AI budgets actually receive them once milestone gates apply.
