What happened

The article discusses the rise of AI agents as the primary users of the internet, shifting from human to agent-driven traffic. It highlights that agents now generate over half of new articles and most code, and AI-referred consumer traffic shows higher engagement. Key examples include Shopify's eightfold growth in AI-driven store traffic and orders from AI-powered searches growing nearly thirteenfold. The piece outlines the emerging 'B2A economy' where businesses must treat agents as first-class customers. It identifies agent infrastructure, payments, fraud, and identity as areas under strain. The article also presents a market map of agent-related technologies and argues that enterprises will need to embrace agent traffic despite current blocking due to fraud concerns.

Key questions for investors and operators

When evaluating transactions, technology stacks, or commercial partnerships in this space, we recommend looking closely at three questions:

How resilient is programmatic yield on unauthenticated traffic (Safari, Firefox, iOS) without relying on legacy third-party cookies?
Are programmatic deal pipes (PMP, Programmatic Guaranteed) cleanly separated from open-auction floor pricing to prevent rate-card erosion?
What technical controls govern AI crawler access, content licensing telemetry, and first-party audience curation?
