How is this ranking calculated?
Each channel's public subscriber count today minus the subscriber count vidIQ recorded 30 days earlier, highest first. A channel created during the period counts from zero. The list covers channels whose country on YouTube is South Korea. YouTube rounds public subscriber counts, so gains are measured between rounded numbers.
How often is this list updated?
Once a day. vidIQ last updated the figures on this page on October 30, 2026.
Why is a channel missing from this list?
A channel is left out when vidIQ has no subscriber count for it from the start of the period, when it hides its subscriber count, or when vidIQ does not track it yet. So is a channel whose country on YouTube is not South Korea.
