Linux traffic in the US jumps to 9.8%: bots and AI agents may be behind the surge

Linux's share of internet traffic in North America unexpectedly doubled within a few weeks, reaching a historic high. According to Statcounter, the figure rose from the usual 3–5% to roughly 10% between May and June. However, analysis by Cloudflare suggests this spike is unlikely to stem from more people using Linux on desktop computers.

Cloudflare, whose data is based on HTTP requests, recorded that Linux accounted for 9.8% of US-based internet traffic from July 4 to August 1. This number closely matches Statcounter's metric. But when the company applied a filter to exclude automated requests, Linux's share dropped to 6.4% — a level close to the operating system's typical usage.

The gap between the figures indicates that the growth is driven by programs, not people. A sharp increase over a short period could be explained by one or more large web services expanding automated activity, such as data scraping, web crawling, or cloud workloads. The spread of AI agents — software that performs tasks without human oversight — is likely another contributing factor.

The situation is compounded by Cloudflare CEO Matthew Prince's statement in June that bots have surpassed humans in generating web traffic for the first time. "Welp, that happened faster than I predicted," he wrote on X on June 3. "Thought it would be end of 2027, then early 2027, but agentic traffic growing so fast that bots have now passed human traffic online for the first time."

While no dataset is perfect, both Statcounter and Cloudflare point to a similar trend. This suggests that Linux, traditionally dominant on servers but a niche choice for personal computers, now plays a larger role in automated processes. The exact reason for the sudden rise remains unclear, but the most plausible explanation is the expansion of AI systems and cloud infrastructures, which predominantly run on Linux.
