DataDome has released The AI Traffic Report Q2 2026, revealing that AI agent traffic surged 45% quarter-over-quarter to 17.7 billion requests. The analysis shows Meta has taken over the AI web, MCP traffic has emerged as a measurable signal, and a growing gap between consumption and value is driving a wave of agent trust policy adoption .
AI agent traffic surged 45% QoQ to 17.7 billion requests in Q2 2026, up from 12.2 billion in Q1.
Meta dominates: Meta-ExternalAgent grew 74% and Meta-WebIndexer grew 163% QoQ, together accounting for the majority of AI agent traffic.
ChatGPT-User traffic declined 6% QoQ, yet ChatGPT still commands 80-88% of AI referrals, growing 17% QoQ.
MCP traffic is now measurable, with peaks approaching 500,000 requests per day and clear daily usage cycles.
54% of DataDome customers have implemented agent trust policies to distinguish valuable agents from those that simply consume infrastructure.
DataDome's network processes 5 trillion signals daily across 400+ enterprises .
DataDome, the leader in bot and agent trust management, today released The AI Traffic Report Q2 2026: Agentic Traffic Surged 45%, With Meta Taking the Lead, an analysis of the scale, composition, and shifting dynamics of AI traffic across the web from April to June of 2026 .
The findings reveal that AI agent traffic is not only growing at an accelerating rate but also changing in ways that challenge how organizations control agent access, infrastructure costs, and business value. AI agents are becoming more purposeful, more varied, and harder to manage with a one-size-fits-all approach .
AI agent traffic surged 45% QoQ. DataDome's network processed 17.7 billion AI agent requests in Q2 2026, up from 12.2 billion in Q1 . Meta has taken over the AI web. Meta-ExternalAgent grew +74% QoQ and Meta-WebIndexer grew +163% QoQ. Together, Meta's two agents now account for the majority of all AI agent traffic on DataDome's network, a dominance that did not exist in Q1 .
The nature of Meta's traffic is changing. Meta-ExternalAgent works like a researcher, traveling across the web reading content to train AI models. Meta-WebIndexer works more like Google's crawler, continuously reading and indexing web content so Meta AI can give users up-to-date answers. In June 2026, Meta-WebIndexer exceeded Meta-ExternalAgent in monthly volume for the first time, suggesting Meta is investing increasingly in the "answering" side of AI .
Crawl volume and referral value are moving in opposite directions. ChatGPT-User, the top agent in Q1, declined 6% QoQ in absolute request volume. Yet ChatGPT remains the overwhelming leader in referral traffic, commanding 80–88% of all AI referrals every month, and growing +17% QoQ . This divergence highlights a critical distinction for organizations: an agent that crawls consumes resources without returning value, while an agent that redirects traffic brings visitors who may engage with content, click ads, or make purchases .
MCP traffic is now a measurable network signal, with peaks approaching 500,000 requests per day and clear daily usage cycles, reflecting an ecosystem in active exploration . The Model Context Protocol allows AI agents to connect with external tools and services, representing a new data point that will grow as agent architectures become more interconnected .
Agent trust adoption is accelerating. 54% of DataDome customers have already implemented agent trust policies, recognizing that at this scale, distinguishing between agents that serve business objectives and those that simply consume infrastructure is no longer optional .
"Q2 showed us that the ground is shifting faster than most organizations realize. Meta now dominates AI traffic on our network, MCP traffic has emerged as a real signal, and ChatGPT is driving more referral value with fewer crawls," said Jérôme Segura, VP of Threat Research at DataDome. "What the data makes clear is that not all agents are created equal. The organizations building policy around these distinctions are the ones gaining an edge, and that's exactly why agent trust adoption is accelerating" .
