AI Agents Tax the Open Web
Generative search and AI agents increasingly complete research, comparison and discovery tasks without sending users to the underlying websites. Platforms with default distribution, logged-in audiences or unique proprietary data can keep users inside their ecosystems and charge for access to their content. Publishers, review sites, marketplaces and independent ad-supported websites face lower referral traffic, weaker advertising inventory and pressure to pay for customer acquisition. The divide is becoming less about whether a company uses AI and more about whether it owns the user relationship that AI is disintermediating.
