a16z Unveils B2A Economy: AI Agents Emerge as the Internet's Main Users

Venture capital firm Andreessen Horowitz (a16z) has introduced a transformative economic framework dubbed the Business-to-Agent (B2A) economy, signaling a shift where artificial intelligence agents become the primary consumers of digital services. According to a research report published on November 13, 2026, by a16z partners Olivia Moore and Justine Moore, autonomous agents are increasingly replacing human users in decision-making processes, including product selection, service subscriptions, and financial transactions. This evolution suggests that the traditional internet architecture, designed for human interaction, is rapidly pivoting toward a system optimized for machine-led consumption.

Statistical Surge in Agent-Driven Traffic

The shift toward a B2A model is supported by significant growth metrics across major digital platforms. Data reveals that Shopify witnessed an 8-fold year-on-year increase in AI-driven store traffic during the first quarter, while orders specifically generated through AI search mechanisms rose by nearly 13-fold. Furthermore, cybersecurity firm HUMAN Security reported an 8-fold spike in agent-based browser traffic between August and October. These figures underscore the transition of AI from simple assistants to active economic participants capable of executing complex workflows on behalf of their human counterparts.

Key Beneficiaries of the Agentic Shift

The a16z report identifies four primary sectors positioned to capitalize on this emerging economic structure. As agents require specialized protocols for payments and verification, the blockchain and cryptocurrency sectors are expected to play a critical role in providing the necessary trustless infrastructure for these machine-to-machine interactions. The identified categories include:

• Agent Models: The foundational LLMs and specialized frameworks that power autonomous logic.
• Native Agent Products: Innovative services designed exclusively for agent use rather than human interfaces.
• Optimized Traditional Businesses: Legacy enterprises that adapt their APIs and storefronts to be "agent-readable."
• Agent Infrastructure: Tools focusing on security, identity verification, and decentralized payment rails.

The Role of Blockchain in B2A Commerce

Industry analysts suggest that the rise of the B2A economy will necessitate the integration of smart contracts and stablecoins to facilitate instantaneous, micro-transactional payments between agents. Unlike traditional banking systems, which often involve manual approvals and delays, blockchain networks offer the high-frequency settlement layers required for autonomous software. This synergy between Artificial Intelligence and Web3 technology is likely to redefine how value is exchanged across the global digital landscape.

AI agents will replace users in deciding which products to use, which services to subscribe to, and where to spend.

The emergence of the B2A economy marks a fundamental change in the digital ecosystem, moving beyond human-centric design toward a more automated and efficient marketplace. As AI agents continue to scale their presence, the focus for developers and investors will likely shift toward building the underlying infrastructure—ranging from decentralized physical infrastructure networks (DePIN) to specialized agentic protocols—that will support this new era of autonomous internet commerce.
