Forty-seven percent of marketers now label influencer marketing a “must-buy” line item, not a discretionary test budget. That’s not a rounding error. It’s a structural shift in how media planning gets built, and it means the channel has quietly graduated from experimental to essential in the same conversation as paid search and connected TV.
If you’re still pitching influencer budgets as a separate ask from your core media plan, you’re behind. The buyers who used to hedge — “let’s test it with 10% of the budget” — are now writing creators into the plan before they finalize anything else. Something changed. Let’s unpack what, and why it matters for how you allocate spend next quarter.
What “Must-Buy” Actually Means to a Media Buyer
“Must-buy” isn’t marketing speak for “we like it.” In media planning terms, it means a channel has crossed the threshold where skipping it creates measurable risk — competitive risk, reach risk, or performance risk. TV upfronts used to hold that status. Search did too, once. Now creator spend is being talked about in the same breath.
The shift tracks with broader spend data. Creator ad spend has already blown past the $44 billion mark, and growth is outpacing traditional digital channels by a wide margin, according to recent industry tracking covered in our creator ad spend analysis. When a channel grows faster than the categories it used to borrow budget from, buyers stop treating it as incremental and start treating it as foundational.
When nearly half of buyers call a channel “must-buy,” they’re not describing preference — they’re describing a plan that doesn’t work without it.
IAB’s own forecasting has reinforced this. Creator spend is now projected to outrank traditional TV and display in several media plan categories, a finding we broke down in detail in our piece on the IAB creator spend forecast. That’s a genuinely uncomfortable data point for anyone who still budgets creator as a “nice to have” line under social.
Why the Shift Happened Now, Not Three Years Ago
Three forces converged. None of them alone would have done it.
- Measurement finally caught up. Attribution tooling, TikTok Shop conversion tracking, and platform-native analytics have made creator ROI legible in a way it wasn’t in 2022. Buyers can now defend the spend in a budget meeting without hand-waving.
- Budgets grew fast enough to force structure. When creator line items jump 171% in a single planning cycle, as documented in our report on creator budget growth, finance teams stop treating it as an experiment. They start asking for governance, forecasting, and repeatable processes — the hallmarks of a mature channel.
- Platform risk got real. Buyers who watched TikTok’s regulatory uncertainty unfold learned the hard way that single-platform creator strategies are fragile. That pushed diversification, which in turn pushed more formal, multi-platform planning — the kind of planning that earns “must-buy” status because it’s harder to unwind.
None of this happened in a vacuum. It happened because the operational infrastructure around influencer marketing — contracts, payment rails, brand safety tooling — matured enough to support serious money moving through it.
The AI Layer Nobody Saw Coming
Here’s the part most trend pieces miss: AI didn’t just make creator content cheaper to produce. It made buying decisions faster and more defensible. Ad-tech consolidation driven by AI has cut vendor stacks dramatically, per our coverage of AI-driven ad-tech consolidation, which means the tools buyers use to plan, vet, and pay creators are fewer, faster, and better integrated than they were even two years ago. Fewer platforms to manage means fewer excuses to delay the buy.
There’s also a structural workforce shift underneath all this. Creators aren’t freelancers anymore in the traditional sense — many operate as full businesses with production teams, legal counsel, and their own media buying arms, a trend we’ve tracked in creators as business owners. That professionalization makes them easier to slot into formal procurement processes, which is exactly the kind of friction reduction that turns a “maybe” channel into a “must-buy” one.
Where the Money Is Actually Going
Must-buy status doesn’t mean money floods evenly across the creator landscape. It’s concentrating in specific places, and the pattern tells you something about buyer priorities.
Micro and mid-tier creators are absorbing a disproportionate share of new budget, not because they’re cheaper per post, but because platform algorithms increasingly reward engagement density over raw follower count. We covered this shift in TikTok’s algorithm and micro-creator pricing — the short version is that a 50,000-follower creator with a tight, engaged niche audience is now commanding rates that would have gone to a 500,000-follower account three years ago.
Live commerce is the other major destination for must-buy dollars. TikTok Shop live-selling is converting at roughly 30% versus 2-3% for static ecommerce placements, a gap wide enough that any performance-minded buyer has to take notice. We laid out the mechanics in our analysis of TikTok Shop live conversion data. When a channel converts ten times better than the alternative, “must-buy” stops being a debate and starts being math.
A tenfold conversion gap between live commerce and static ecommerce isn’t a trend to watch. It’s a budget reallocation waiting to happen.
The Retention Argument Buyers Aren’t Talking About Enough
Most coverage of creator spend focuses on acquisition — reach, impressions, conversion. But the must-buy case gets stronger when you look at retention. Data on what’s being called the “creator middle class” shows mid-tier creators outperforming top-tier talent on both ROI and audience retention, according to findings in creator middle-class performance data. That’s a durability argument, not just a cost-efficiency one. Buyers who’ve been burned by one-off celebrity creator deals are gravitating toward repeatable, mid-tier partnerships precisely because they hold up campaign after campaign.
The Risk Side of the Ledger
None of this means influencer spend is risk-free just because it’s popular. If anything, must-buy status raises the stakes on governance.
Platform concentration risk hasn’t gone away — it’s arguably grown more urgent as budgets scale. Brands leaning too hard into one platform’s creator ecosystem are exposed to policy changes, algorithm shifts, and regulatory action outside their control, a point we’ve stressed in platform risk and creator diversification. A must-buy channel still needs a diversified buying strategy underneath it.
Compliance is the other pressure point. As creator budgets scale into the tens of millions for individual brands, FTC disclosure requirements and platform-specific labeling rules become a genuine legal exposure, not a checkbox. The FTC’s endorsement guidelines haven’t loosened just because spend has grown; if anything, enforcement scrutiny tends to track dollar volume. Any brand treating creator marketing as must-buy should be treating creator compliance the same way.
Content supply is quietly becoming its own risk category too. With estimates suggesting the creator population is approaching 100 million globally, buyers face a genuine vetting problem, one we explored in the creator supply glut analysis. More supply means more noise, more AI-generated low-quality content competing for the same feeds, and a harder job separating signal from filler. Substack’s recent crackdown on AI-generated “slop” content is an early warning sign for anyone relying on creator-generated UGC at scale — a theme covered in Substack’s AI content purge.
What This Means for Your Next Planning Cycle
If influencer spend is must-buy in your category, treat it with the same rigor you’d apply to any core media line: forecasted budgets, defined KPIs, vendor consolidation where it makes sense, and a documented compliance process. The days of “let’s throw some budget at a few creators and see” are over for brands operating at scale.
Practically, that means:
- Build creator spend into your annual media plan from day one, not as a mid-year add-on.
- Diversify across platforms to reduce single-point-of-failure risk.
- Prioritize mid-tier creators for retention and repeatable ROI, reserving top-tier talent for launch moments.
- Formalize disclosure and compliance review as part of the creator onboarding process, not an afterthought.
- Use frameworks like the IAB creator marketplace framework to standardize how you vet and brief creators across teams.
Industry benchmarking resources are worth watching too. eMarketer’s ad spend forecasts and Statista’s creator economy datasets are useful for building the business case internally, and platforms like Sprout Social publish regular benchmarking reports that help contextualize your own performance against category norms.
Frequently Asked Questions
FAQs
What does “must-buy” mean in influencer marketing budgets?
It means buyers now treat creator spend as a required, non-negotiable part of the media plan rather than a discretionary test. Nearly half of creator buyers currently use this designation, reflecting the channel’s shift from experimental to foundational.
Why are brands increasing influencer budgets so quickly?
Better measurement tools, faster AI-driven ad-tech consolidation, and proven conversion data (particularly in live commerce) have made creator ROI easier to prove and defend internally, which accelerates budget approval cycles.
Are micro-creators really outperforming larger influencers?
In many cases, yes. Platform algorithms increasingly reward engagement density over follower count, giving micro and mid-tier creators pricing power and retention advantages that used to belong exclusively to larger accounts.
What’s the biggest risk of treating influencer marketing as must-buy?
Over-concentration on a single platform and under-investment in compliance are the two biggest risks. Must-buy status increases dollar exposure, which raises the stakes on both platform diversification and FTC disclosure compliance.
How should brands budget for influencer marketing going forward?
Treat it like any core media line: build it into annual planning, diversify across platforms, prioritize mid-tier creators for retention, and formalize compliance review as part of standard creator onboarding.
The brands winning right now aren’t the ones with the biggest creator budgets — they’re the ones who moved creator spend into core planning before it became mandatory. Start there: pull influencer spend into your next annual plan as a governed line item, not a test.
