Field note
Ramp's August 2026 AI Index provides a current view of enterprise transaction and adoption signals.
New Runtime reading: Spend data is valuable because it observes purchasing behavior, but it does not prove productivity or causal return. The strongest use is to track category and vendor movement alongside separate workflow and outcome evidence.
Evidence boundary: this item uses the listed public sources and keeps vendor, author, or reporter claims attributed. The queued page is an editorial synthesis, not an independent validation of every reported metric.
