Claims
- McKinsey projects AI agents could mediate between $3 trillion and $5 trillion of global consumer commerce by 2030.
- The agentic commerce automation spectrum spans six levels, from human-assisted price comparison at level one to autonomous machine-to-machine price negotiation at level six.
- Brands will increasingly need to optimize for algorithmic selection by AI agents rather than appealing solely to human shoppers.
- Retailers must make product catalogs, pricing, inventory, and return policies machine-readable via APIs to be discoverable by AI purchasing agents.
- Brands that withhold inventory and pricing data behind non-API interfaces risk being systematically bypassed by AI shopping agents in favor of more data-accessible competitors.
Key quotes
If a brand only focuses on looking good to humans but hides its inventory data, the AI agents will simply ignore it.
At the highest level, your personal AI agent negotiates directly with a store's AI agent to get the best price and shipping terms.
Stores that expose their pricing and stock data through clear software connections will dominate this new landscape, while those relying purely on flashy marketing will lose out as machines make the actual purchasing choices.
