## Questions the record answers

**Which spend management platform do AI models name first most often?** Ramp, in 49% of first choices for a mid-market B2B company in the September 2026 Edition, from 59 labels. The index calls that a clear leader.

**Does the answer change with the size of the company?** Small business: Ramp at 51%. Mid-market: Ramp at 49%. Enterprise: Coupa 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 Airbase; paraphrase Ramp; comparative Ramp; budget-constrained Ramp; scale-constrained Ramp; negative Brex. The table above has the counts.

**How stable is one answer?** Asked again with nothing changed, the models moved their own first choice 68% of the time across the repeat sample; Across the categories asked twice, a leader's share moved 3 points at the median and the index calls a change only above 6 points.

**Where do the answers come from?** Twelve of the twelve models return sources. Their 67 answers here cite 815 pages; the sites cited most are emburse.com, gartner.com, ramp.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.
