How a product gets on this list
The judge reads every answer
A product is on the record because a model named it in an answer and the judge labeled the naming: first choice, alternative, mention, caution or warning, each with the sentence it came from. 81 products were named for cloud cost management platform this edition.
10 labels and a first choice
A product is ranked once it carries 10 labels in a segment and at least one first choice there. Below that it is named but not ranked, and it says so on its page. The vendor table that folds spellings into products is versioned; this page was scored under v2026-11.3.
The noise floor
The same categories are asked again with nothing changed to measure how much an answer moves on its own. A change in share smaller than the floor is not reported as a change. The repeat, model by model.

Questions the record answers
Which cloud cost management platform do AI models name first most often?
Vantage, in 55% of first choices for a mid-market B2B company in the November 2026 Edition, from 58 labels. The index calls that a clear leader.
Does the answer change with the size of the company?
Small business: Vantage at 65%. Mid-market: Vantage at 55%. Enterprise: IBM Apptio Cloudability at 54%. Each standing is computed within its segment and never pooled.
Which framing changes the answer?
The direct, paraphrase, budget and scale framings count toward share. The product named first differs by framing: direct Vantage; paraphrase Vantage; comparative Vantage; budget-constrained Vantage; scale-constrained CloudZero; negative AWS Cost Explorer. The table above has the counts.
How stable is one answer?
The repeat measurement is published with the next edition.
Where do the answers come from?
Fourteen of the fourteen models return sources. Their 72 answers here cite 778 pages; the sites cited most are finout.io, cloudaware.com, amnic.com. The category page lists them all.
Can a vendor pay to be on this list?
No. A product is on the record because a model named it. A vendor can claim its page, propose corrections to the vendor table and be told when its standing moves; it cannot change a label, a share or a rank, and the publisher's conflicts are disclosed on the method page.
