Influencer Marketing in 2026: How Creator-Led Media Is Reshaping Advertising

Influencer marketing is no longer competing for a line item in the media plan. It is rapidly becoming one of the largest and fastest-growing advertising ecosystems in the market.

According to the Interactive Advertising Bureau’s 2025 Creator Economy Ad Spend & Strategy Report, creator-led advertising spend in the United States is projected to reach USD $37 billion by 2025, a 26 percent year-over-year increase and nearly four times faster growth than the overall media industry. This figure is materially higher than narrower influencer-only forecasts, because it reflects a broader shift. Brands are no longer paying simply for posts. They are investing in creators as a scalable media and distribution layer.

This matters because it reframes the role influencer marketing plays inside modern marketing organisations. It is no longer an experimental channel sitting alongside paid social. It is absorbing budget traditionally allocated to digital video, display and even television, because it consistently delivers what those channels increasingly struggle to maintain at scale: attention, relevance and trust.

At the same time, tension remains. Fifty eight percent of consumers say they have purchased a product because of an influencer endorsement, yet more than a quarter actively distrust influencer marketing as a category. These insights are drawn from the 2025 Influencer Trust Index published by the National Advertising Division (NAD) of BBB National Programs. The opportunity is massive, but so is the risk. This is why 2026 will not be about growth alone. It will be about professionalisation.

Creator-led media has outgrown the influencer label

The reason the creator economy is expanding so much faster than the broader advertising market is simple. The category has outgrown its original definition.

Creator-led advertising now includes influencer partnerships, branded content, paid amplification of creator assets, affiliate commerce, live shopping, podcasts and long-form integrations. What unites these formats is not platform or placement, but ownership of audience attention.

Creators operate as decentralised media owners. They distribute content natively inside platforms, build habitual viewership and shape cultural relevance at a speed brands struggle to replicate internally. As investment accelerates, the distinction between influencer marketing and digital media buying will continue to blur. The brands seeing outsized returns are already planning for this convergence.

Influence is built through proximity, not scale

Despite the growth of the channel, many brands still rely on outdated assumptions about what influence looks like.

Follower count remains the most visible signal, but it is an incomplete proxy for impact. Different creator tiers drive different outcomes, and effectiveness depends on how those tiers are deployed within a broader strategy.

Industry benchmarks consistently show that nano and micro creators generate higher engagement rates on average. On TikTok, creators with fewer than 10,000 followers regularly achieve engagement rates above 10 percent, while comparable creators on Instagram average above 6 percent. These metrics reflect interaction density and perceived proximity, rather than reach.

Larger creators, by contrast, deliver scale more efficiently, but with lower engagement rates per follower. Their value lies in visibility and awareness, not necessarily depth of interaction.

The implication is not that reach no longer matters. It is that reach and credibility are delivered through different mechanisms. Rather than relying on a single creator tier, brands increasingly assemble portfolios of creators, combining reach-led and proximity-led influence to achieve scale without sacrificing trust.

This approach mirrors how audiences consume media today. Fragmented, personalised and community-led.

How creator scale is actually distributed

Fabulate Discovery data shows that the creator economy is heavily skewed towards smaller creator tiers, with scale coming from volume rather than celebrity.

Across TikTok, Instagram and YouTube, the dataset includes 348.1 million creators, distributed as follows:

• Nano creators (under 10K followers): 313.7 million
• Micro creators (up to 50K followers): 24.6 million
• Mid-tier creators (50K to 500K followers): 3.24 million
• Macro creators (500K to 1M followers): 2.78 million
• Mega creators (1M+ followers): 0.53 million
  
  

This distribution highlights a structural reality. More than nine in ten creators sit in the nano tier, while creators with more than one million followers represent a fraction of one percent of the ecosystem.

The implication for brands is not that smaller creators are inherently better, but that influence at scale is achieved through aggregation, repetition and systems, not through reliance on a small number of high-profile individuals.

What Fabulate Discovery data reveals about creator scale

Fabulate Discovery data reinforces why portfolio-based creator strategies consistently outperform single-creator approaches.

This imbalance is most pronounced on TikTok, which alone represents nearly 80 percent of all creators analysed. On the platform, more than nine in ten creators are nano, reinforcing why discovery, trend participation and volume-based creator portfolios align more closely with how influence actually operates.

Instagram presents a more balanced profile, but still skews heavily towards smaller creators, while YouTube remains a specialist platform built for depth rather than scale.

Together, these patterns underline a simple truth. The creator economy is not designed around a handful of high-profile influencers. It is built on scale, repetition and proximity.

Growth is exposing the limits of legacy media

The rapid growth of creator-led advertising is not happening in isolation. It is accelerating against a backdrop of declining reach and influence across many legacy media channels.

Ben Gunn, Co Founder and Chief Revenue Officer at Fabulate, believes the shift reflects a deeper change in how audiences consume and trust media.

“What we are seeing is not a sudden love for influencer marketing. It is a response to the reality that traditional media no longer commands attention in the way it once did. Audiences are more fragmented, less reachable through broadcast channels and far more selective about what they engage with.”

Creators, Gunn argues, are filling a gap that traditional media has struggled to adapt to.

“Creator-led content shows up where people already spend their time and it feels native to those environments. That is why creator marketing continues to grow at multiples of the broader media market, even as many legacy channels fight declining audiences and diminishing influence.”

However, Gunn is careful to separate growth from maturity.

“As more budget flows into creator marketing, the expectations on the channel inevitably rise. Brands need to understand who they are working with, how performance is measured and how risk is managed. You cannot scale trust on gut feel alone.”

This perspective points to where the category is heading next.

“The future of this category depends on putting the right systems around it. The goal is not to make creator marketing feel like traditional media, but to give brands confidence as it becomes a core part of the mix. Trust, measurement and brand safety are what will determine whether this growth is sustainable.”

The scale of this shift has consequences. As creator-led advertising absorbs more budget and responsibility, the tolerance for inconsistency diminishes. What once worked as an experimental channel is now being judged by the standards of core media investment.

The real constraints are operational, not creative

If creator-led advertising is growing nearly four times faster than the rest of the media market, why does distrust persist?

The answer lies less in content quality and more in how influencer marketing is executed.

Measurement remains inconsistent. There is no accepted industry standard for evaluating creator performance. Engagement metrics are interpreted differently across teams. Conversion tracking is often crude. Brand impact is measured sporadically rather than systematically.

Vetting is under-resourced. Many marketers spend less than 30 minutes vetting a creator, despite creators publishing thousands of pieces of historical content across platforms. Manual checks do not scale in a market of this size.

Brand safety is reactive. Issues are frequently identified after content goes live, not before partnerships are approved. As creator portfolios expand, this risk compounds.

Workflow has not kept pace with spend. Influencer marketing is still managed through emails, spreadsheets and disconnected tools, even as budgets rival other major media channels. 

In many organisations, the challenge is structural. Teams are set up to run campaigns, not creator portfolios. Procurement processes are built for traditional media buys, not ongoing creator relationships. Risk frameworks have not evolved at the same pace as creator velocity. This mismatch makes scale harder than it needs to be.

Measurement in 2026 will prioritise confidence, not vanity metrics

As creator budgets grow faster than almost any other media category, scrutiny inevitably follows.

The next phase of influencer marketing measurement will not be about collecting more metrics, but about using the right ones to support decision-making. Likes and comments will remain relevant, but increasingly as signals of resonance rather than proof of success.

Attention metrics such as view duration and completion will grow in importance as indicators of message absorption. Brand lift studies will move from occasional experiments to baseline hygiene. Commercial outcomes will be contextualised rather than treated as the sole measure of value.

In a $37 billion market growing at multiples of the broader industry, reporting is not the objective. Confidence is.

Trust is the asset brands are really buying

Trust is what differentiates creator-led media from traditional advertising. It is also what makes it fragile.

Consumers are increasingly alert to undisclosed partnerships, misaligned endorsements and creator behaviour that conflicts with brand values. When trust breaks, it breaks publicly.

In 2026, trust will be protected through process, not instinct. That means documented vetting, proactive brand safety checks, clear disclosure standards and partnerships with creators who already demonstrate genuine alignment with the brand or category.

Finding brand advocates is not a creative exercise. It is a systems problem.

The brands winning in 2026 will build infrastructure, not campaigns

Creator-led advertising is not just growing. It is outpacing almost every other media category.

The question facing brands is no longer whether influencer marketing works, but whether they are equipped to run it at the level the market now demands.

The winners in 2026 will be those who treat influencer marketing as infrastructure. Measured with rigour. Managed with systems. Scaled with confidence.

When a channel is growing four times faster than the market around it, the only real risk left is treating it like an experiment.
