Agentic commerce is now measurable with public data. Below are the figures we were able to verify against primary, dated sources, as of June 2026.
Methodology
We include a figure only if a primary source (the relevant company's official publication or a dated public report) documents it. Where an analyst report is only reachable through press coverage, we flag it and keep attribution to the original source. No unsourced projection is carried on this page.

What these figures say (and do not say)
Agentic traffic starts from a low base but grows very fast (from +1,200% in early 2025 to +393% YoY in Q1 2026, an acceleration in absolute terms), and it now converts better than classic human traffic. The absolute share of agentic commerce within total e-commerce remains a minority and is not reliably quantified by a primary source: we therefore do not publish a market-share percentage or a 2030 projection on this page.
For merchants the signal is nonetheless clear: a fast-growing, higher-converting channel whose access runs through machine readability and standards adoption (UCP, ACP, AP2).
