What Is Trending on TikTok and Instagram in May 2026?

May is one of the busiest months for social because multiple behaviours collide at once.

Audiences are:

• Planning summer
• Revising for exams
• Booking travel
• Shopping seasonal fashion
• Reacting to entertainment launches
• Following music tours
• Searching TikTok like a discovery engine
• Using content to express identity and routine

The biggest mistake brands make is treating trends like random viral moments.

They’re not, they’re behavioural signals.

So instead of asking: “What is trending?” Ask:

Why is this trending, and what does it tell us about what people care about right now?

That’s where useful strategy starts.

Which May 2026 Cultural Moments Should Brands Plan Around?

May 2026 is packed.

But the goal isn’t to jump on everything.

It’s to choose moments that naturally fit your brand, audience and category.

Music and live entertainment

• Harry Styles world tour
• BTS tour
• Bruno Mars, Silk Sonic and Anderson .Paak tour
• Billie Eilish concert film

These moments are driven by fandom.

And fandom is one of the most powerful forces on social.

It comes with:

• Emotion
• Language
• Community
• Behaviour

The smartest brands don’t hijack fandoms.

They understand them.

When you get it right, you don’t just post about a moment.

You become part of the conversation.

Film and cinema

• The Devil Wears Prada 2
• Mortal Kombat II
• The Mandalorian and Grogu
• Michael Jackson biopic

Film isn’t just content.

It’s aesthetic.

It’s identity.

It’s something people want to step into.

The best brands translate that into:

• Styling
• humour
• reactions
• category-specific takes

TV and streaming

• Stranger Things
• Good Omens Season 3
• Spider-Noir
• Lord of the Flies

TV behaves differently.

It builds over time.

It creates:

• Recurring conversation
• Fan communities
• Ongoing content formats

The opportunity isn’t one post.

It’s sustained participation.

Festivals and cultural moments

• Cannes Film Festival
• Brighton Festival
• RHS Chelsea Flower Show
• Hay Festival

These moments signal:

• Outdoor living
• Hosting
• Cultural discovery
• Planning behaviour

This is less about reacting.

More about helping people prepare.

What Trending Songs Should Brands Use in May 2026?

Trending sounds are everywhere.

But using them properly is what matters.

Key tracks include:

• “i love me”
• “RUNWAY”
• “Waiting Room”
• “Fun, Fun, Fun”
• “Never Felt So Alone”

The rule is simple:

Don’t pick a sound because it’s trending. Pick it because it fits the idea.

Use sounds to:

• Enhance emotion
• Match tone
• Increase shareability

Not to replace a creative idea.

The sound should help the content travel.

It shouldn’t be the content.

How Should Brands Actually Use Trends Without Looking Desperate?

The brands that win don’t copy trends.

They translate them.

Every trend should pass three tests:

1. Audience fit

• Would our audience recognise this?
• Would they care?
• Would they expect us to have a point of view?

2. Brand fit

• Can we make this feel natural?
• Does it connect to what we do?
• Are we adding anything useful or interesting?

3. Behaviour fit

• What behaviour is behind this trend?
• Planning, shopping, identity, entertainment?
• How can we contribute to that behaviour?

If it doesn’t pass all three, don’t post it.

Silence is better than cringe.

How Should Brands Build a May 2026 Content Plan?

A strong May plan combines:

• Cultural moments
• Category trends
• Sounds
• Product relevance
• Audience behaviour
• Search intent

A simple weekly structure

Week 1: Summer + launches

• Summer styling
• Watch party content
• Cinco de Mayo hosting

Week 2: Music + exams

• Concert prep
• Study routines
• Energy and snack content

Week 3: Cannes + outdoors

• Red carpet content
• Garden and hosting
• Behind-the-scenes

Week 4: Travel + planning

• Day trips
• Packing
• Reading lists
• Bank holiday content

The key is consistency.

Not one-off trend chasing.

What Should Brands Avoid in May 2026?

Avoid:

• Jumping on fandoms without understanding them
• Forcing products into cultural moments
• Overusing trending sounds with no idea
• Posting generic “relatable” content
• Ignoring TikTok search behaviour
• Using children in content without proper safeguards

Trends aren’t shortcuts.

They’re signals.

How Can Brands Use TikTok Trends for Search Visibility?

TikTok is now a search platform.

That means your content needs to be:

• Searchable
• Clear
• Intent-driven

Use on-screen text and captions like:

• “Best SPF for summer make-up”
• “What to wear to a Harry Styles concert”
• “Easy BBQ recipes for May”
• “Best UK day trips in May”

This helps:

• Users find your content
• AI systems understand it
• Platforms distribute it

The same applies to Instagram:

• Reels captions
• Carousel headlines
• Alt text

Search isn’t separate anymore.

It’s part of social.

TikTok and Instagram Trend FAQs

What are the biggest trends in May 2026?

Summer planning, fandom, food, travel, beauty routines, exam season and creator-led content.

Should brands use every trend?

No. Only use trends that fit your audience, brand and behaviour.

Are sounds more important than ideas?

No. Sounds amplify ideas. They don’t replace them.

How do you make trend content feel original?

Use the format, but add your own perspective, category insight or usefulness.

How quickly should brands react?

Fast, but not rushed. Relevance matters more than speed.

Trends Work When Behaviour Comes First

May is full of opportunity.

But the brands that win won’t be the ones posting the most.

They’ll be the ones understanding what those trends mean.

The pattern is clear:

• Summer is shaping behaviour
• Fandom is driving culture
• Travel is moving from inspiration to action
• Exams are shaping content consumption
• Search is shaping discovery

At Pepper, we don’t treat trends like a checklist.

We treat them like a map.

A map of what people are:

• Thinking
• Planning
• Buying
• Watching
• Sharing

That’s how brands should approach TikTok and Instagram in May 2026.

Not by chasing the feed, but by understanding it.
