Top 3 Most Popular & Trending Instagram Niches for 2025 (That Can Also Work on YouTube)
If you’ve been endlessly scrolling Instagram Reels for hours (like I just did for 8 hours straight!), you’ve probably noticed certain types of content going insanely viral. After analyzing the trends, I’ve handpicked the top 3 most popular and 12 trending niches that can explode in 2025 — or even sooner — if you start now.
What’s exciting is that these niches are not only goldmines for Instagram, but you can also start a YouTube channel around them. Even better, there’s little to no competition yet, so the opportunity to go viral is huge. Some Instagram accounts in these niches are gaining millions of followers in just a month!
Before You Start: 2 Key Rules for Any Social Media Creator
Before I reveal the top 3 niches, there are two very important points you must understand. These apply to any creator, whether you’re on Instagram, YouTube, or any other platform:
- Find Your Right Interest — Choose a niche based on what you are genuinely interested in, not just because someone else is doing it. For example, don’t jump into gaming just because your friend is making gaming videos. When you work in a field you love, ideas flow naturally, and you’ll never run out of content.
- Create Valuable Content — “Value” means your content should help, entertain, or educate your audience. For example, on my own channel, I share tips and tricks that my viewers can actually use. If your audience learns something from you, they’ll keep coming back.
If you follow these two points, your chances of failing drop dramatically.
Trending Instagram & YouTube Niche #1: Funny AI Celebrity Character Videos
Imagine creating an AI-generated model of a famous celebrity like Cristiano Ronaldo or Lionel Messi, and then making funny short videos with them. Sounds crazy? It’s actually one of the hottest niches right now.
One Instagram creator gained 1 million followers with just 41 posts using this exact idea. They make AI versions of famous people and place them in humorous scenarios, posting the clips as Reels. Every video pulls in millions of views.
On Instagram, this type of content is already killing it. On YouTube, it’s still untapped — but there’s a catch. YouTube’s monetization rules mean you should:
- Always mark your content as “altered content.”
- Use your own real voice for narration. If you rely entirely on AI voiceovers, you might face monetization issues later.
Not sure how to make AI celebrity videos? Just search on YouTube for AI celebrity video tutorials. There are dozens of tools available.
Trending Instagram & YouTube Niche #2: AI Character Giving Daily Tech Tips
This niche combines two powerful trends: AI avatars and practical everyday tips. Here’s how it works:
- Create a permanent AI character model (this will be your “digital host”).
- Use this AI character in every video to share simple but valuable tips — such as protecting your Instagram account, hidden smartphone settings, or new app features.
One creator has already reached 1 million followers with just 188 posts in this niche. The videos are short, to the point, and provide quick solutions that anyone can use.
For YouTube, the same rules apply:
- Mark your videos as “altered content.”
- Use your own voice for better monetization safety. If you must use AI voiceovers, run them through an audio editor (e.g., Audacity) to make them unique and avoid copyright or reuse issues.
Trending Instagram & YouTube Niche #3: Reviewing New AI Tools
AI tools are being launched every week, and people want to know what’s worth using. This niche is simple but incredibly profitable:
- Pick new AI tools as they launch.
- Review their features, show how they solve problems, and demonstrate what they can create.
One creator with just 97 posts already has over 500k followers by reviewing different AI tools. Brands in the AI space are eager to pay influencers to promote their software. If you build a following in this niche, companies will reach out to you directly for sponsorship deals worth thousands of dollars.
You can start on Instagram, YouTube, or both. For YouTube, you can either be the face of your channel or use an AI character. Again, if you use AI-generated voiceovers, make sure to edit them before uploading.
Final Thoughts
These three niches — AI celebrity videos, AI characters giving tips, and AI tool reviews — have massive potential for 2025 and beyond. The best part is, they’re still underexplored on YouTube, giving you the chance to dominate early.
To get started, remember:
- Pick the niche you can stick with long-term.
- Provide value in every video.
- Leverage AI tools for creation, but follow monetization-safe practices.
If you’re ready to create viral Instagram Reels or YouTube Shorts, start experimenting today. Who knows — your first million followers might be closer than you think!
