For OpenAI's commerce features to succeed, it's not enough to build one-click checkout. They must fundamentally retrain hundreds of millions of users to trust a new purchasing workflow inside a chatbot, breaking deeply ingrained habits of searching on ChatGPT then buying on Google or Amazon.

AI agents shop based on optimized specs, not human heuristics like brand trust. This shift to "agentic commerce" could neutralize the power of major brands like Walmart and Amazon, and eliminate the interpersonal relationships that sustain local, small businesses.

It's a mistake to think of an agent as 'User V2.' Most enterprise and consumer agents (like ChatGPT) are inherently multi-tenant services used by many different people. This architecture introduces all the complexities of SaaS multi-tenancy, compounded by the new challenge of managing agent actions across compute boundaries.

To enable agentic e-commerce while mitigating risk, major card networks are exploring how to issue credit cards directly to AI agents. These cards would have built-in limitations, such as spending caps (e.g., $200), allowing agents to execute purchases autonomously within safe financial guardrails.

A core pillar of modern cybersecurity, anomaly detection, fails when applied to AI agents. These systems lack a stable behavioral baseline, making it nearly impossible to distinguish between a harmless emergent behavior and a genuine threat. This requires entirely new detection paradigms.

The next phase of AI will involve autonomous agents communicating and transacting with each other online. This requires a strategic shift in marketing, sales, and e-commerce away from purely human-centric interaction models toward agent-to-agent commerce.

For years, businesses have focused on protecting their sites from malicious bots. This same architecture now blocks beneficial AI agents acting on behalf of consumers. Companies must rethink their technical infrastructure to differentiate and welcome these new 'good bots' for agentic commerce.

Amazon is suing Perplexity because its AI agent can autonomously log into user accounts and make purchases. This isn't just a legal spat over terms of service; it's the first major corporate conflict over AI agent-driven commerce, foreshadowing a future where brands must contend with non-human customers.

The financial system is unprepared for the coming wave of AI agents. These agents will perform tasks and require payment, creating trillions of micropayments. Current infrastructure from Stripe, Visa, or Mastercard cannot handle this volume, creating a massive opportunity for new protocols to facilitate the 'agent economy'.
