State of Agentic Traffic – April 2026: Agentic browsers generate nearly three-quarters of agentic traffic

The State of Agentic Traffic is HUMAN’s monthly benchmark on how AI agents are showing up across the web. Each edition reports on agent mix, sector destinations, and activity patterns observed across the Human Defense Platform, extending findings from the annual 2026 State of AI Traffic & Cyberthreat Benchmark Report.

This is a monthly report by HUMAN’s Satori Threat Intelligence Team, which monitors all agentic traffic and other observed automated traffic and produces insights surrounding the trends, developments, and the threat landscape.

Key Findings

Across the top 10 agents in April, browser-based agents, led by Perplexity’s Comet and OpenAI’s Atlas, accounted for roughly 71% of observed activity.

Concentration at this level has practical implications. Browser-based agents arrive with user-agent strings, cookies, and session patterns that closely resemble human browsing. For sites receiving this traffic, the relevant questions are which agent is arriving, on whose behalf it is acting, and whether that action is authorized.

This concentration also tells us something about adoption. Agentic browsers are a consumer category, installed and used like any other browser. That is the interface through which users are choosing to run agent-driven tasks.

Comet Browser led all agents in April at 48.12%, followed by Atlas at 21.33%, Claude Chrome Extension at 17.33%, and ChatGPT Agent at 8.55%. The remaining six agents in the top 10 (Genspark, Browserbase, Browseruse Cloud, ManusAI, Hyperbrowser, and Antigravity) collectively accounted for less than 5% of observed traffic.

The media industry captured the most AI agent traffic at 45.62%, with ecommerce following at 38.20%, and travel at 14.12%. Together, these three industries captured 98% of agentic traffic in April, consistent with the pattern identified in the 2026 State of AI Traffic & Cyberthreat Benchmark Report.

Month over month, the sharpest growth came from federal and government services (+254%) and SaaS companies (+41.5%), though each remains a small slice of total volume. Media and e-commerce continue to grow (+13.3% and 6.5% respectively), reinforcing their position as the two dominant destinations. Education saw the largest contraction, shrinking to just 3.2% of its size in March, at -96.8%

Three-quarters of agentic activity (69.57%) touched product and search routes: browsing product listings, reading articles, and running searches. This echoes the annual finding that most agents today are exploring product listings rather than completing transactions.

The remaining activity splits across authentication (9.22%), user account routes (8.55%), miscellaneous (4.82%), content engagement (4.68%), and checkout and payment (3.16%).

Data reflects agentic traffic observed across the Human Defense Platform during April 2026. Agent identification combines behavioral signal analysis, user-agent attribution, and publisher-level integration where available. Sector and route categorization reflects the destination endpoint, not the agent operator’s intent.

The benchmarks above show agentic activity across HUMAN’s Defense Platform. On your own site, most analytics tools can’t distinguish AI agents from human visitors, let alone identify specific agents or classify their intent.

AgenticTrust is HUMAN’s trust and control layer for AI agents. It gives security, fraud, commerce, and marketing teams continuous visibility into every agent session, classifies intent as the session unfolds, and enforces adaptive policies based on what agents are actually doing.
