Reach Is Out, Attention Is In: What Jupiter Festival Miami Means For 2027 Budgets

U.S. creator ad spend is projected to hit $43.9 billion in 2026, and a growing slice of it — $24.3 billion across on- and off-social amplification — is really ad buying with creator-made creative. That number, laid out in the IAB's 2025 Creator Economy Ad Spend & Strategy Report and first cited by Digiday, is the clearest evidence yet that the "reach is dead" talk at the first Jupiter Festival Miami isn't just conference patter. The money has already moved.

The festival ran Oct. 6–9, 2026, at the Miami Beach Convention Center, drawing more than 2,300 media, entertainment, and sports leaders, per its organizers. MCH Group, Art Basel's parent, took a 20% stake in June. The IAB signed on as a founding partner; YouTube was the founding sponsor.

What did speakers actually say about reach?

BBC Studios' senior VP of digital, Jasmine Dawson, put it flatly on a Day 1 panel: "Reach should not be the primary KPI." Her distinction — "building an audience is not fandom and fandom is not audience" — matters because big reach numbers say nothing about whether anyone does anything next.

Adelaide CEO Marc Guldimann added a measurement frame on Day 2: "If you want to rate the quality of an opportunity, look at the probability of attention." His AU metric scores placements 0 to 100 on attention and outcomes, and on Oct. 14 — a week after Miami — Adelaide launched a partner designation program matching survey and outcome data directly to AU.

Analyst Evan Shapiro went furthest, unveiling his 2026 Creator Ecosphere Map on stage Oct. 8 after previewing it in a post titled "The Era of Reach is Over. Welcome to The Affinity Era."

How big is the creator-as-inventory shift?

YouTube Ads' head of creator and creative, Amanda Tarpey, said marketers are "waking up" to creators' trust and authenticity — "There's a lot of experimentation, but the infrastructure is not standardized." That second sentence is the real story for paid media teams.

The IAB found 48% of creator ad buyers now treat creators as a "must buy," behind only paid search and social. Digiday's breakdown of the report shows:

• $13.2 billion of the 2026 total goes to paid amplification on social, up 48% from $8.9 billion
• $11.1 billion goes to amplification beyond social, up 56% from $7.1 billion

One correction worth keeping: YouTuber Hudson Matter claimed "almost half of the world is on YouTube." DataReportal puts ad reach near 2.77 billion monthly — roughly a third of the world, closer to half of internet users. Use the smaller figure.

What's happening with streaming and sports inventory?

Transmit co-founder Scott Young said streaming lets buyers "aggregate valuable ad supply that would have otherwise gotten lost," singling out women's sports on free ad-supported streaming. Transmit's software builds in-stream units like picture-in-picture placements without adding ad breaks, and the company joined the Google Ad Manager Technology Partner Program — meaning formerly direct-only premium sports inventory is entering programmatic pipes.

One claim needs a flag: WNBA chief growth officer Colie Edison said customers are "three times more likely to purchase from a brand that they support." No underlying study could be located. Treat it as a claim, not a benchmark.

There's a budgeting catch, too. NBCUniversal Telemundo's Claudia Chagui described turning Rockefeller Center into a FIFA World Cup fan village. EMARKETER projects U.S. ad spending growth slowing from 15.6% in 2026 to 9.4% in 2027, warning CTV budgets built on tournament and midterm inventory should expect normalization.

Why does top-of-funnel spending matter now?

Former LVMH North America CEO Anish Melwani described luxury's drift toward "more lower funnel performance," while insisting great brands "understand how much you have to keep doing at the top." Shapiro predicted "an explosion of premium vertical content in the next 18 months." And NBCU Rock Studios' Andrew Gottlieb offered the sharpest caveat for AI-scaled creative: "AI can do a lot, and it can create a lot of content, but it can't make people care about that content."

IAB CEO David Cohen tied it together on Day 3: "The one thing that we simply cannot do is the same thing that we've done year-over-year." Per festival co-founder William Mellis, Cohen also called for a common cross-platform ad currency.

Here's what nobody said on stage: BBC Studios, YouTube and Transmit were sponsors, and Adelaide and NBCUniversal sell the alternatives. That doesn't make them wrong — sellers see shifts first because they must prove value. But treat "reach is over" as a hypothesis. Attention scores and affinity grades are better questions than "how many saw it," yet none is an answer until tied to incremental sales in your own accounts.

Miami 2027 is already on the calendar. By then, expect the argument to shift from whether reach is wrong to which replacement is right.
