What began as a niche internet joke has quietly become a defining feature of today’s online feeds. “AI slop”—a term used to describe low-effort, auto-generated content—has now entered mainstream language. It reflects growing unease over the quality of material flooding platforms like YouTube.

A Kapwing report highlights just how widespread the issue has become. As of October 2025, between 21% and 33% of YouTube feeds may be made up of AI-generated “slop” or closely related “brainrot” videos. These range from repetitive Shorts and spam-like clips to endlessly recycled visuals. They are designed to maximise clicks rather than creativity.

While AI video tools are being used productively in film, advertising, and education, the report points to a parallel ecosystem. Here, creators mass-produce content with simple prompts. Kapwing defines AI slop as careless, low-quality automated content. Brainrot refers to compulsive, nonsensical videos that erode attention through repetition.

To gauge the scale, Kapwing analysed the top 100 trending YouTube channels in every country. It also reviewed viewership, subscribers, and estimated revenue. Furthermore, it tracked the first 500 Shorts shown to a new user account.

The findings reveal stark regional patterns. Spain leads in total subscribers to AI slop channels, crossing 20 million. This is driven by a few highly popular accounts. South Korea, meanwhile, dominates in sheer scale. AI slop channels there generate over 8.4 billion views, far ahead of most countries.

Some individual channels stand out globally. The most-subscribed AI slop channel is based in the US. It publishes Spanish-language, anime-themed videos. The most-viewed channel, however, is based in India—Bandar Apna Dost—which features hundreds of similar videos starring a photorealistic monkey. It has crossed two billion views, with estimated annual earnings above $4 million.

The report also flags concerns for YouTube itself. In tests simulating a new user’s feed, over 20% of Shorts were AI-generated, while nearly one-third qualified as brainrot. As this content increases, questions are emerging around advertiser trust, brand safety, and content quality.

Kapwing concludes that AI slop is no longer a fringe trend. Nearly one in ten fast-growing YouTube channels now rely entirely on AI-generated videos. The challenge for platforms and viewers alike will be preserving originality. They must also learn to evaluate critically what algorithms serve next.
