Agentic Commerce is Here: When AI Becomes Your Customer

The rules of commerce are being rewritten before our eyes.

At the India AI Impact Summit, Mastercard unveiled something that would have sounded like science fiction just two years ago. They showed an AI system that conducts complete transactions without human intervention. No app. No credit card entry. No human scrolling through options. Just an algorithm evaluating value, price, and preferences before clicking buy.

This is agentic commerce. It is about to change everything you know about marketing.

The Shift from Omnichannel to Agent to Agent

For the past decade, marketers have perfected omnichannel experiences. They focused on seamlessly connecting web, mobile, social, and in-store touchpoints. But AI agents don't browse menus or appreciate slick UI. They hit APIs. They parse structured data. They make decisions in milliseconds.

As Gareth Cummings of eDesk noted, a meaningful share of customer interactions will happen agent to agent in 2026.

Imagine a customer's personal AI assistant checking your inventory and comparing your prices against competitors. It could verify delivery times and negotiate terms without the customer ever visiting your website. Your brand's visibility now depends on how machine-readable your product data is instead of how beautiful your homepage looks.

What This Means for Marketers

The implications are profound.

1. AEO Replaces SEO Answer Engine Optimization is the new Search Engine Optimization. During the 2025 holiday season, AI chatbot traffic doubled year over year. It drove $262 billion in revenue. Search conversations are now two or three times longer and more complex. Instead of searching for a blue shirt, customers ask for a blue top for a formal bridal shower in San Francisco. If your catalog can't be interpreted by AI, you won't show up in recommendations.

2. The Share of Model Metric Just as you tracked share of voice and share of search, you will now track share of model. This measures how often AI assistants recommend your brand versus competitors. This becomes your primary visibility metric.

3. API First Everything Your product catalog, pricing, inventory, and policies must be accessible via clean and documented APIs with sub-second response times. If an LLM can't parse your data, you effectively don't exist to the systems doing the buying.

The Window is Open For Now

According to McKinsey, 62% of organizations are still experimenting with agentic AI. Only 23% are scaling. Major players like Walmart, Target, Home Depot, and Lowe's are already building agentic solutions. But most competitors haven't started.

Your 90-day action plan:

• Weeks 1 to 2: Audit your product data schema. Ensure GTINs, SKUs, live pricing, and machine-readable policies are in place.
• Weeks 3 to 4: Expose catalog and inventory via authenticated APIs with clear SLAs.
• Weeks 5 to 6: Launch a pilot for agent to agent interactions. Start with order status queries.
• Weeks 7 to 12: Implement monitoring for cost per resolved intent and begin tracking share of model.

The Bottom Line

The customer journey isn't just changing. It's becoming invisible. When AI agents handle discovery, comparison, negotiation, and purchase, your job shifts. You move from attracting human attention to becoming the brand that machines trust and recommend.

Commerce has always evolved. But this isn't an evolution. It's a paradigm shift.

The question isn't whether agentic commerce will transform your industry. It's whether you'll be ready when your next customer is an algorithm.
