The Forecast
Agents are coming for the purchase order
Gartner projects that by 2028, 90% of B2B buying will be intermediated by AI agents, channeling more than $15 trillion in spend through automated agent-to-agent exchanges — systems that research vendors, compare offers, negotiate, and execute purchases with minimal human involvement. It's not purely a future scenario: Forrester's 2026 State of Business Buying, drawn from nearly 18,000 global buyers, found that 94% already use AI somewhere in the purchasing process. The research step that now precedes a buying decision is increasingly done by a machine.
