In October 2025, McKinsey published one of the most consequential commerce forecasts in years: by 2030, agentic commerce — in which AI agents shop, negotiate, and transact on behalf of humans — could generate $1 trillion in orchestrated US B2C retail revenue, and $3 trillion to $5 trillion globally. McKinsey describes this as “a seismic shift” comparable to the web and mobile revolutions — and argues that it could unfold even faster because AI agents ride the rails of existing commerce infrastructure.

For enterprise commerce leaders, this prediction is not a distant horizon. It is an architectural imperative for investment decisions happening right now.

What Agentic Commerce Actually Means

Agentic commerce describes a world in which the consumer no longer directly interacts with your storefront, your sales team, or your marketing. Instead, an AI agent — operating on the consumer’s behalf with their stated preferences and constraints — navigates the entire purchasing journey: searching, comparing, negotiating, and executing transactions autonomously.

This is not science fiction. The technical infrastructure — including the Model Context Protocol (MCP), Agent-to-Agent Protocol (A2A), and the Agentic Commerce Protocol (ACP) co-developed by OpenAI and Stripe — is being deployed right now. By 2028, Gartner forecasts that 90% of B2B buying will be AI agent intermediated, pushing over $15 trillion of B2B spend through AI agent exchanges. (Source: Gartner, October 2025) The B2C transition, while slower, is accelerating rapidly.

McKinsey is explicit: high-frequency, low-consideration purchases — household staples, replenishment items, subscription services — are already being delegated to agents. The enterprises that make themselves agent-readable today will capture disproportionate share of this category. (Source: McKinsey, October 2025)

The Infrastructure Gap That Will Determine Winners

McKinsey identifies three infrastructure requirements for agentic commerce readiness that expose the gap between cloud-native enterprise platforms and legacy commerce stacks: data quality (agents amplify data problems — stale pricing, inaccurate inventory, and incomplete product data are fatal to agent discovery); real-time connectivity (an agent that recommends an out-of-stock product loses trust permanently — real-time inventory APIs are non-negotiable); and orchestration capability (the ability to process, fulfil, and confirm agent-initiated transactions at machine speed requires an architecture designed for programmatic interaction, not just human browsing).

Legacy monolithic commerce platforms, designed for human-navigated storefronts, cannot meet these requirements without fundamental re-architecture. API-first, cloud-native, composable platforms — like Novitates Cloud Commerce — are designed exactly for this challenge.

The B2B Agentic Commerce Imperative

While consumer agentic commerce captures headlines, the B2B transformation is equally profound. By 2028, 90% of B2B buying will be agent-intermediated — and the enterprises whose products, services, and fulfilment capabilities are accessible via well-documented, real-time APIs will be the ones that agents discover, evaluate, and purchase from. Those whose commerce infrastructure requires human-navigated portals will be structurally disadvantaged.

Gartner frames this with unmistakable clarity: products designed with composable microservices, API-first, cloud-native, headless architectures will establish a significant competitive moat. (Source: Gartner, October 2025) For B2B commerce leaders, this is the investment thesis: API-readiness is market access in an agent-intermediated world.

Preparing Your Commerce Infrastructure for the Agent Economy

The path to agentic commerce readiness is not a single technology purchase. It requires: an orchestration-first commerce platform that synchronises real-time pricing, inventory, and fulfilment; a composable API layer that exposes product data, eligibility logic, and transaction capabilities to agent systems; predictive AI that can manage demand signals from agent-driven purchasing patterns; and a resilient, elastic infrastructure that can scale to agent-initiated transaction volumes that may be orders of magnitude larger than human-browsing-driven volume.

Novitates Cloud Commerce is built for exactly this architecture. Book a discovery session to see how your current commerce infrastructure maps against the agentic readiness requirements of 2028 and 2030.
