How much of YouTube is AI slop now

Quick answer

If your feed has started feeling weird, cats in soap operas, fake movie trailers, the same narrated story with a new thumbnail, you're seeing something real. Here's what the data says, with links to every source.

What 125x is: 125x is a web app at 125x.app. You connect your YouTube subscriptions, and it gives you a feed of the latest videos from the channels you follow, each with a summary: a verdict, the 5 key takeaways, and the spoiler, plus Actionable and Lessons tabs with more tips. You read that and decide what's actually worth opening.

The numbers

• Nearly 1 in 10 of the fastest growing YouTube channels in the world in July 2025 were showing only AI-generated videos. The Guardian counted 9 of the top 100 using data from Playboard (The Guardian, Aug 11, 2025).
• When Kapwing set up a brand new YouTube account, 104 of the first 500 Shorts it was shown were AI slop, about 21%. 165 of the 500, about 33%, were what it called brainrot (Kapwing, AI Slop Report (Oct 2025)).
• Kapwing looked at the top 100 trending channels in every country, about 15,000 channels, and found 278 that post only AI slop. Together they had more than 63 billion views, 221 million subscribers and an estimated $117m a year in revenue (The Guardian, Dec 27, 2025).
• YouTube says more than 1 million channels used its own AI creation tools daily, on average, in December 2025 (YouTube Blog, Neal Mohan's 2026 letter).

What YouTube is doing

On July 15, 2025 YouTube renamed its "repetitious content" monetization rule to "inauthentic content." It lists "AI-generated content made with generic or unoriginal templates giving the impression of mass production" among the things that can't earn money (YouTube Help, channel monetization policies).

In his 2026 letter, CEO Neal Mohan named "managing AI slop" as a priority and said YouTube is building on the systems it uses against spam and clickbait to reduce low-quality, repetitive videos (YouTube Blog, Neal Mohan's 2026 letter). YouTube also started stepping up enforcement against egregious clickbait in December 2024, beginning in India (YouTube Official Blog (India), Dec 18, 2024).

How 125x helps

125x builds your feed from the channels you subscribed to, so you start with people you picked. Every video gets a summary with a verdict (watch, skim, or skip) and the reason, 5 key takeaways, action items, lessons, and the spoiler, which is the thing the title and thumbnail are teasing, just said plainly.

Shorts feeds are where most of the numbers above come from. In 125x you see your subscriptions with the gist of every video up front.
