Stage criteria

Visa Intelligent Commerce

Stage: pilot since 2025-12-18

Judged pilot, not live. Visa's own releases describe controlled transactions with named partners: on 18 December 2025 Visa said hundreds of agent-initiated transactions had been completed with partners, with US pilots in closed beta; on 8 April 2026 Intelligent Commerce Connect was announced in pilot; on 20 October 2026 the BILL/Billtrust deployment was announced as a first live pilot. No Visa primary source found states general availability, and Visa's 10 June 2026 release does not state general availability of Connect. 2025-12-18 is the earliest primary-source evidence of pilot transactions; pilots may have begun earlier.

Mastercard Agent Pay

Stage: live since 2025-11

General availability is US-wide; global expansion was reported as underway through 2026. The live date is month precision only: Mastercard said on 30 September 2025 that all US cardholders would be enabled by mid-November 2025, and its CEO said on 30 October 2025 that the remaining US issuers would be enabled in November; no Mastercard primary source confirming completion was found, so no day is asserted.
