Top 50 Most Subscribed YouTube Channels

The number of subscribers a YouTube channel has clearly indicates its success and popularity among its audience. Simply put—the more, the better.

So, which channels are King when it comes to subscribers? We’ve put together a list of the most subscribed channels based on data from Wikipedia.

Let’s take a look.

Top 100 YouTube Search Terms Globally

Below, we’ve compiled a list of the most searched YouTube terms in June 2025. It’s based on search volume data obtained from Semrush’s Keyword Analytics for YouTube tool.

Of course, this data fluctuates over time and the most popular search terms change. So, if you want fully up-to-date data, we’d highly recommend using Semrush’s tool to find it.

The data in the following list is for global search volume rather than regional search volume. The data was also gathered specifically from YouTube searches, not from Google searches.

OK, let’s get into it.

Key YouTube Statistics

• Kids Content Dominance: 6 out of the top 50 channels (Cocomelon, Kids Diana Show, Vlad and Niki, Like Nastya, ChuChu TV, Pinkfong) are children’s content, collectively commanding over 771 million subscribers.
• Multi-Billion View Gap: Despite having fewer subscribers (294M vs 395MM), T-Series has nearly 4 times more total views than MrBeast (297B vs 83B views), highlighting different engagement patterns between individual creators and media companies.
• Language Distribution: While English remains prominent, Hindi is the second most common primary language among top channels, with 9 channels primarily producing Hindi content, reflecting India’s growing digital presence.
• Creator vs Brand: Of the top 50 channels, approximately 40% are individual creators or personality-driven channels (like MrBeast, PewDiePie, Mark Rober) while 60% are corporate/brand channels, showing both paths can lead to massive success.
• Content Volume Variation: There’s a massive disparity in video output – some top channels like Mark Rober have just over 200 videos total, while others like SET India and Zee TV have over 150,000 videos, suggesting quality vs quantity strategies can both work.
• Educational Entertainment: Channels mixing education with entertainment (Mark Rober, 5-Minute Crafts) show strong performance, with Mark Rober achieving 68M subscribers with just 210 videos, demonstrating high per-video value.

How Marketers Can Leverage YouTube Stats

YouTube statistics offer a goldmine of valuable information for marketers, providing insights that can significantly enhance their strategies and campaigns. Here’s why YouTube stats are crucial for marketers:

• Audience Understanding: Stats reveal detailed information about the audience, including demographics, preferences, and behaviors. Marketers can gain a deeper understanding of who is watching their content, and this enables them to create campaigns that are more targeted and personalized.
• Identify Trends: Stats provide real-time insights into current trends and popular topics. Marketers can capitalize on these trends by aligning their content with what captures the audience’s attention. This ensures that campaigns remain relevant and engaging.
• Optimized Search Strategies: YouTube is a search engine in itself, and understanding popular search terms can inform SEO strategies. Marketers can enhance discoverability and YouTube search rankings by tailoring their video titles, descriptions, and tags to align with the terms actively searched by their audience.
• Content Optimization: By analyzing stats, marketers can pinpoint the types of content that resonate most with their audience. Insights into the most-viewed videos, popular search terms, and subscriber patterns can empower marketers to optimize their content strategy for maximum impact.
• Collaboration: Understanding which channels are the most popular can aid marketers in identifying valuable collaboration opportunities. Partnering with a YouTuber with a substantial audience can significantly contribute to the growth of their (marketer’s) channel.

How to Find YouTube Keywords

Semrush’s Keyword Analytics for YouTube is great for finding search term data for YouTube keywords quickly and easily. This tool is a separate app, so you’ll need to access it via the Semrush App Center. Then, open the tool and you’ll get three options:

• Keyword Research
• Fast growing keywords
• Top Videos

Click “Get started” within the “Keyword Research” box.

On the next page, choose to see data for the past month by clicking the “Last Month” tab.

This will give you a better idea of trends over a longer period of time. At the top right of the screen, select a specific region or “All Regions” to view global keyword data.

Now, you’ll get a list of keywords with the “Search Volume” and “Competitive Rate” (a score out of 100 indicating how much competition there is for the term).

“Fast growing keywords” is another great feature that allows you to identify trending keywords that are surging in popularity.

You’ll then see a list of keywords with their “Search Volume” and the extent of volume increase during your selected time period.
