The fastest-growing YouTube channels of October 2026

Who gained the most YouTube subscribers in October 2026. MrBeast topped our weekly list for five weeks straight, then a Brazilian creator edged past him. 6 of the top 10 came from Latin America or Spain, and a channel with 70,100 subscribers nearly doubled.

Shanu ChandFounder, TubeGrade & Vidgrade · Data: TubeGrade’s weekly YouTube rankings. The October list is the one built on 2 November 2026: subscribers gained per 30 days, between readings about a month apart (early October to the start of November) · 3 min read

For five weeks in a row, the same name sat at the top of our list of the fastest-growing YouTube channels: MrBeast, adding three to five million subscribers a month.

In the list that covers October, he was second. Lucan Pevidor, a Brazilian creator with 48.5M subscribers, gained about 5.4M in the month. MrBeast gained about 5M.

And he wasn’t the only new name near the top. 6 of the 10 fastest-growing channels in October came from Latin America or Spain. Here’s who grew, by how much, and what the list can and can’t tell you.

How the list works: we compare each channel’s subscriber count with its count about a month earlier and express the gain per 30 days. Only channels over 100,000 subscribers are ranked. Gains are rounded the way YouTube rounds the counts it shows.

Brazil has three of the ten, the most of any country: Lucan Pevidor, Natan por Aí and Gabrielmiranda_ofc. Spain’s TadeVlogs grew +16% in a month, the fastest rate in the top 10. Argentina’s Alejo Igoa and Mexico’s Susy Mouriz complete the six.

One thing to know before reading too much into that. Five of these ten weren’t on any of our September or earlier October lists. That isn’t because they suddenly took off: we added them, with about 2,000 other big channels, on 2 October, and a channel needs a month of readings before we can rank it. October is the first month we can see them at all.

So the fair reading is this: now that our data covers more Spanish- and Portuguese-language channels, they take 28 of the top 100. The United States has 23, and Mexico and India 14 each.

Here is where the steadiest channels sat on every weekly list since the end of September.

Only three channels held a top-10 place on all five October lists: MrBeast, Mark Rober and Stokes Twins. The rest of the top 10 changed from week to week.

As for first place, the gap is smaller than it looks. In that list MrBeast had 524M subscribers, and YouTube shows a count that size in steps of 1 million. Our readings saw it move from 519M to 524M. A difference of 0.4 million sits inside one of those steps. In the next week’s list, built on 9 November, the order was the same: Lucan Pevidor first, MrBeast second.

YouTube rounds public subscriber counts to three significant figures, so for the biggest channels a month’s gain is only accurate to the nearest step. That’s why we show “about”.

Raw gains favour the biggest channels. Look at growth as a share of a channel’s size instead, among the top 100 with over 5 million subscribers:

VocaVoca - Kids Songs & Nursery Rhymes grew +17% in a month, to 10.5M. And CGTN, China’s international state broadcaster, is the only news channel on this short list: +14%, to 9.1M.

A percentage on a channel this big still means a lot of people: +17% of 8.9M is about 1.5M new subscribers.

Our breakout list ranks a different group: channels that started the month with 50,000 to 2 million subscribers, by how fast they grew. Here are the ten fastest.

Nerdy Sage Dos went from 70,100 to 136,000 subscribers in 35 days. Spread over 30 days, that’s +81%. Our readings for it were 35 days apart, so we show the pace, not a calendar month.

Of the 100 breakout channels, 39 were from the United States and 21 from India. For 21 we don’t know the country, because the channel doesn’t show one.

We publish a country’s list once it has at least 50 ranked channels. In the October list, 14 countries had one. Here’s the leader in each.

Each country links to its full list, which updates every Monday.
