Today, September 15, 2026, IAB held the industry’s first-ever CreatorFronts at Convene on 360 Madison Avenue in New York — a marketplace event that put creator advertising on the same stage, literally, as IAB’s Podcast Upfront and PlayFronts for the first time ever. That’s not a small gesture. Upfronts are how TV networks have sold ad inventory to Madison Avenue for decades. Creators just got seated at that table.

The data IAB brought with it is the part worth sitting with. US creator ad spend is projected to hit $44 billion in 2026, up from $37 billion in 2025 — roughly a 19% jump, running about four times faster than the overall media industry. And 48% of creator ad buyers now call creators a “must buy,” which puts creator spend right behind paid search and social media in how brands actually plan their budgets.

If you’ve ever had a brand rep hem and haw about “testing creator” as a line item, that language just got a lot harder to justify. Here’s what happened, what the numbers mean, and how to actually use them.

What CreatorFronts Actually Was

Ad-industry upfronts exist to do one thing: get buyers and sellers of ad inventory in the same room before budgets lock for the year. TV’s had them forever. Podcasts got one in IAB’s Podcast Upfront, now in its fifth year. Gaming got PlayFronts. Creators never had a dedicated version — creator ad money got negotiated deal-by-deal, platform-by-platform, without the kind of standardized, industry-wide marketplace moment that tells buyers “this category is real, budget for it now.”

That changed this week. Main-stage programming covered cross-platform creator influence, creator-led media networks, and — genuinely useful for anyone doing deals without a lawyer on retainer — a session from Lowenstein Sandler LLP on the legal questions tangled up in creator contracts right now. Meta, YouTube, Acast, and CyberAgent all had stage time alongside it, which tells you who IAB thinks the buyers in the room actually care about hearing from.

None of that is the headline, though. The headline is IAB putting a number on the category and telling the room it’s growing faster than everything else they’re buying.

The $44 Billion Number, and Why It’s Not Just a Press Release Line

IAB’s data isn’t a one-year snapshot. It’s a trend line, and trend lines are harder to wave off than a single splashy figure:

• 2021: $13.9 billion
• 2024: $29.5 billion — more than double in three years
• 2025: $37 billion — up 26% year-over-year
• 2026 (projected): $44 billion — roughly another 19% jump

Creator ad spend growing roughly 4x faster than the broader media industry, which IAB pegs at around 5.7% overall growth, is the actual story here. Total media budgets are basically flat by comparison. Creator budgets are compounding.

One thing worth being precise about: this figure measures dollars brands intentionally put into creator partnerships — sponsored content, amplified sponsored posts, planned creator adjacencies. It’s not counting affiliate commissions, subscriptions, tips, or merch. So this is specifically brand ad spend, the exact bucket you’re negotiating against when a marketing team says “we don’t have budget for that.”

Worth flagging if you’ve seen an earlier number: IAB’s November 2025 report put creator ad spend at $37 billion for 2025. The $44 billion figure that showed up at CreatorFronts in September 2026 is the 2026 projection — a different year, not a revised version of the same forecast.

What “Must Buy” Actually Means

Here’s the featured stat, and it’s worth unpacking instead of just repeating.

48% of creator ad buyers call creators a “must buy” channel — meaning nearly half the people setting media budgets now treat creator spend the way they’d treat paid search or paid social: a line item you fund by default, not one you have to justify from scratch every quarter. IAB’s data ranks it just behind those two channels, ahead of most traditional formats.

That’s a real shift in language. “Must buy” isn’t “worth testing” or “showing promise.” It’s budget category, same tier as the stuff that’s been locked into media plans for a decade.

How Should You Actually Use This Data When Pitching a Brand?

1. Lead with the trend line, not the headline number. “$44 billion” is easy to tune out. “Creator ad spend has more than tripled since 2021 and is growing 4x faster than the rest of media” is a sentence a brand’s finance team has to reckon with.
2. Name the 48% must-buy stat when a brand hesitates on budget. If nearly half of buyers already treat creator spend as default, “let’s test it small” is a weaker starting position than it was a year ago — say so directly.
3. Use the upfront framing to push for standing budget, not one-off campaigns. TV networks don’t sell single spots at upfronts — they sell season-long commitments. If IAB is treating creators the same way, frame your own pitch as a retainer or ongoing slot, not a single sponsored video.
4. Cite the category growth rate against the brand’s own category, if you can find it. A beauty brand spending flat year-over-year on traditional media while creator spend in their category climbs is a gap you can point to directly.
5. Don’t skip the legal conversation. IAB dedicated stage time to creator-contract legal issues for a reason — this is a good moment to tighten your own rate cards, usage terms, and renewal language before, not after, a brand comes back asking for more.

Who Should Actually Act on This

Creators currently negotiating a brand deal. This is the single most useful moment this year to bring third-party data into a rate conversation instead of just your own media kit numbers. IAB is a trade body brands already trust — that’s leverage you don’t usually get handed for free.

Creators who’ve been told “we don’t have a creator budget yet.” That excuse gets weaker every quarter this trend holds. Worth revisiting brands that passed on you six months ago with this data in hand.

Anyone building brand-deal infrastructure into their workflow. If you’re using platform-native deal tools like TikTok One or navigating YouTube’s replacement for BrandConnect, this is the macro context explaining why platforms keep building more of this infrastructure, not less — the money funding it is actually growing.

Creators outside the most obvious ad categories. LinkedIn’s B2B creator marketplace and Twitch’s expanded Sponsorships program are both evidence this isn’t just a beauty-and-lifestyle phenomenon — the “must buy” shift shows up across categories buyers are funding right now.

Where to Be Skeptical

IAB is a trade association funded by the advertising industry, including the platforms and agencies presenting on its CreatorFronts stage. A report that tells its own membership “this category is booming, budget accordingly” is exactly the report you’d expect a trade body to publish — that doesn’t make the underlying numbers wrong, but it’s the reason to treat $44 billion as directionally real rather than independently audited to the dollar.

It’s also worth being honest about what “must buy” doesn’t guarantee. Forty-eight percent of buyers calling creators a must-buy category is an industry-level shift in budget philosophy. It’s not a promise that your specific rate goes up, or that any individual brand’s budget for you specifically grows this quarter. Macro trend and micro outcome are different things, and this data is genuinely useful for the room-tone of a negotiation — not a guarantee of the number that comes out of it.

And the growth comparison cuts both ways. Four times faster than a media industry growing at roughly 5.7% overall sounds dramatic because the baseline is so low — creator spend is compounding off a smaller number than TV or paid social ever did. Real growth, worth citing. Just not evidence the category has caught up to those channels in total dollars yet.

Our Take

The thing that actually matters here isn’t the $44 billion figure by itself — trade bodies publish optimistic projections every year, and creators have heard “the creator economy is booming” enough times to be numb to it. What matters is IAB putting creator advertising on the same institutional footing as TV and podcast upfronts, with a legal session on the agenda and a stat specifically measuring how brands talk about budget priority.

That’s the part with actual teeth for your next pitch email. Not “creators are having a moment” — a specific, sourced, industry-body number saying nearly half of ad buyers already treat you as a default line item, not an experiment. Use it plainly. Cite it by name. And if a brand still tries to treat your rate like a rounding error on a test budget, that’s exactly the gap between what IAB’s own buyers say and what that particular brand is actually doing — worth pointing out directly, in those words.
