About 330 YouTube channels have at least 20 million subscribers , based on the public Wikitubia category listing for “Twenty million subscribers.”

What that means

  • That count is a rough public estimate, not an official YouTube total.
  • The actual number can change over time as channels gain or lose subscribers.
  • For context, public sources suggest there are tens of millions of YouTube channels overall, so 20 million subs is an extremely rare tier.

Quick context

A separate discussion source claimed the number is closer to 500, but that appears to include broader interpretations and is less directly verifiable than the category listing.

TL;DR: the best publicly visible count I found is around 330 channels with 20 million subscribers or more.
