UK Creator Partnerships Forecast at £1.217 Billion. IAB Still Hunting a Shared View

Advertiser investment in UK creator partnerships is on course to clear £1 billion for the first time in 2026, according to a first-of-its-kind IAB UK study published Tuesday. The forecast is £1.217 billion for the year — rounded to £1.2 billion in the trade body's own summary — up 26% from £966 million in 2025.

That 2025 total was already up 20.1% from £804 million in 2024. IAB UK, working with the Institute for Advertising and Media Statistics (IRM), says creator partnerships grew more than twice as fast as UK digital advertising excluding the category (9.6%). Against the official £40.5 billion UK Adspend figure, the £966 million in 2025 was about 2.4% of the market.

The measure is narrower than a casual "influencer spend" headline. For the study, creator partnerships means revenues from campaigns on creators' own digital platforms — production and distribution revenues plus digital rights. It excludes advertising adjacent to creator content, subscriptions, events, product sales, and paid amplification of creator campaigns. Amplification is already counted elsewhere in IAB UK's Digital Adspend (social and online video). Industry experts interviewed for the study said amplification could potentially run two to three times partnership revenues; the report flags that estimate as something to treat with caution.

The UK number landed in the same week as IAB's inaugural CreatorFronts in New York, part of a Global Creator Week spanning 17 markets. On stage and in follow-up reporting, the U.S. framing reused IAB's earlier projection that U.S. creator ad spend will reach $44 billion in 2026 — up from a $37 billion 2025 projection in the November 2025 Creator Economy Ad Spend & Strategy Report, and after the category more than doubled from $13.9 billion in 2021 to $29.5 billion in 2024. Digiday and The Drum both put that $44 billion figure at the center of the New York pitch: standardization of views, measurement, and "buyability" so CFOs will keep writing larger checks.

James Douglas, IAB VP of the Experience Center, told Digiday that preliminary responses to the Trusted Creator Brand Deal Initiative survey — with fuller findings due next month — cluster around three stubborn gaps: what counts as a view, how performance is measured, and creator buyability. In The Drum's account of his keynote, he put it bluntly: a market approaching $44 billion still does not share a single definition of its basic unit of value. "The creator economy built the train before it built the tracks," he said. Improvisation works when the market is small; at this scale, he argued, it "is going to break."

Platform sellers showed up with their own proof points. Digiday reported Meta's Karin Tracy citing a 19% reduction in cost-per-action from creator commerce initiatives — a Meta stage claim, not an independent audit. Ultra Pouches CMO Ankur Goyal framed creators as a creative production line for paid media rather than a separate vanity channel, the better to sell the spend internally.

The commercial read for operators is the gap between the spend forecast and the plumbing. UK partnership revenue is now large enough for IAB UK to publish a dedicated market size. U.S. buyers are being told the category is on a $44 billion track. Neither fact settles what a view is, how much brands actually spend once amplification and adjacencies are added back, or whether board-level buyers can reconcile rate cards across platforms. The £1.217 billion is the new UK benchmark. The unresolved unit of account is what CreatorFronts was selling as the next unlock.
