With AI enabling precise control over media spend, key performance indicators are changing. Brands now move beyond simple Return on Ad Spend (ROAS) to more sophisticated metrics like incremental ROAS and contribution margin, reflecting a new emphasis on profitable growth rather than just volume.

AI's most significant impact is not just campaign optimization but its ability to break down data silos. By combining loyalty, e-commerce, and in-store interaction data, retailers can create a holistic customer view, enabling truly adaptive and intelligent marketing across all channels.

Influencing $3 billion in Black Friday sales, AI shopping agents automate both product discovery and price hunting. This ushers in an era of "self-driving shopping" that forces radical price transparency on retailers, as AI can instantly find the absolute cheapest option online for any product.

Walmart's primary view of AI is offensive, focusing on growth opportunities like creating a personalized, multimedia e-commerce experience. This shifts the narrative from AI as merely a defensive efficiency tool to a strategic growth driver, fundamentally changing how people shop.

Focusing on AI for cost savings yields incremental gains. The transformative value comes from rethinking entire workflows to drive top-line growth. This is achieved by either delivering a service much faster or by expanding a high-touch service to a vastly larger audience ("do more").

Agentic commerce isn't just a substitute for existing online shopping. It can unlock new spending from high-income individuals whose primary barrier to consumption is time, not money. By automating purchasing, agents reduce this "time cost of consumption," potentially adding new, incremental dollars to the economy.

The next frontier in e-commerce is inter-company AI collaboration. A brand's AI will detect an opportunity, like a needed digital shelf update, and generate a recommendation. After human approval, the request is sent directly to the retailer's AI agent for automatic execution.

Beyond booking meetings for high-value deals, AI agents can be empowered to handle the full sales cycle for lower-priced products. They can answer questions, provide discount codes, and conduct follow-up, creating a significant, automated revenue stream with no human sales involvement.

Rather than fully replacing humans, the optimal AI model acts as a teammate. It handles data crunching and generates recommendations, freeing teams from analysis to focus on strategic decision-making and approving AI's proposed actions, like halting ad spend on out-of-stock items.
