The State of Agentic B2B Commerce: AI is improving commerce. It’s not revolutionizing it.

AI is reshaping commerce in genuinely exciting ways, but not always in the ways the headlines suggest. Agentic commerce in B2C is best understood as a strong and meaningful evolution of the consumer experience, one that will make shopping faster and smarter, but that faces real structural limits on how far it can go. Understanding where those limits are, and why, turns out to be essential context for what’s happening in enterprise B2B procurement.

The Productivity Shift Is Real

LLMs have genuinely transformed how people work. The most remarkable aspect of this moment isn’t just that people are faster at the things they already know how to do, it’s that they can now credibly accomplish things outside their areas of expertise that they used to depend on others for:

• Instead of sending a contract to legal for review, instruct an LLM to highlight risks and identify areas to redline.
• Instead of spending days getting marketing’s polish on a slide deck, spend an hour producing something crisp, on-brand, and ready for final review.
• Instead of spending a week designing a new software module, spend a few hours vibe-coding a working prototype that fits your existing tech stack.

The same shift is happening in our personal lives such as financial planning, travel research, and major purchase decisions, all accelerated from days to minutes. This context matters because it sets a high bar for what we should expect when LLMs enter commerce.

The Promise of Agentic Commerce

Consumer product research has been largely the same experience for over a decade. You read independent reviews, scan comparison sites, visit multiple product detail pages and reviews, and, depending on how indecisive you are, repeat the cycle across multiple sessions. It works, but it’s slow and fragmented.

LLMs hold a genuine promise here: take your natural language requirements, draw on deep product data across the market, and surface a precise recommendation without ever showing you a catalog. No scrolling, no tab overload, no agonizing over star ratings. That’s a meaningful improvement.

But is it revolutionary?

For that bar, consider a useful benchmark: revolutionary means behavior change at the scale of Amazon Prime’s impact on purchase frequency, or the smartphone’s impact on where and how often people shop. It means consumers fundamentally restructure how they approach buying, not just where they start their search.

Why It Falls Short of Revolutionary

Protocol fragmentation is slowing the foundation. For LLM-powered shopping to fulfill its promise, merchants need to expose their product data in standardized ways. That infrastructure is still nascent. Google’s Universal Cart Protocol is still in its early stages. OpenAI’s Agentic Commerce Protocol, still in its early stages, has already faced adoption challenges that prompted OpenAI to reassess its eCommerce strategy. Meaningful broad merchant participation, the prerequisite for any answer engine to become a credible marketplace, remains a multi-year challenge.

The open ecosystem is already closing. Even once protocols mature, agentic shopping faces a more fundamental problem: the platforms that matter most won’t allow it to occur from outside of their own walls. Amazon has made clear it will not be scraped by agents. Others will follow. The commercial incentive to keep shoppers inside a proprietary experience is too strong. What this means in practice is that any agent-assisted comparison engine will have systematic blind spots, and consumers will know it.

Conversational shopping will become table stakes, not a differentiator. Traditional marketplaces are already integrating LLMs into their own experiences. The result is that the research improvement LLMs offer will be ubiquitous across every shopping destination, Amazon, Google, Walmart, and every vertical retailer. When every marketplace has it, it’s no longer a reason to change behavior. It’s just the new baseline.

The net effect: answer engines become another place to shop, not a fundamentally different way to shop. Consumers will continue to move across platforms, compare across ecosystems, and apply the same skepticism they bring to any single source of recommendation. That’s a welcome upgrade to the existing experience, not a revolutionary restructuring of it.

Where B2C Ends and B2B Begins

The B2C story is useful precisely because it reveals the pattern: agentic commerce improves the experience within existing structures more than it dismantles them. In the consumer world, that’s mostly fine, the stakes are lower and the landscape is relatively open. Enterprise B2B procurement is a different world entirely. The requirements go well beyond finding the right product, they include supplier contracts, approved vendor lists, budget authorities, compliance controls, audit trails, and variable requirements between every supplier/buyer relationship. Agents will change how enterprise buyers discover and purchase goods.

The more interesting question is how, and that’s what Part 2 explores.
