Who supports which agentic commerce standard

Last verified 2026-06-18

A dated directory of named supporters and authors of each standard. Every row links to the primary source it comes from. This is a starting set, expanded as new commitments are verified.

How to read this: a company appears here only when a primary source (an official announcement or specification) names it in connection with a standard. We do not infer support from press mentions or logos.
