Jesser, a YouTuber with almost forty million subscribers, drew polite applause at Brandcast 2026. When Dwyane Wade took the stage, who has a fraction of that audience on YouTube, the whole hall rose to its feet. On 13 May 2026, YouTube CEO Neal Mohan stood on the Lincoln Center stage in New York and, with the words “Welcome to the YouTube Era”, announced this year’s upfront. Trevor Noah hosted, and Chappell Roan sang.
Custom Sponsorships lets AI dynamically surface creators’ videos that fit a brand’s specific moment. The brand sets the goal, and the model finds the scene. Multimodal ad creation through Gemini, Veo and Nano Banana cuts production costs. The brief goes in as a prompt, and the output is a finished ad. Buy with Google Pay handles checkout on Connected TV. The viewer presses twice and has ordered.
For the creator economy, this is the first upfront where matching, ad production and checkout are explicitly switched to AI-mediated mode. YouTube is redrawing where the creator’s work ends and the media buyer’s work begins.
Custom Sponsorships decide on the brand’s behalf
A brand wants to react to a trend, a season or a cultural moment. Instead of an agency brief and manual searching for creators, AI scans YouTube’s library and “dynamically surface videos tailored to a brand's desired moment”. The creator does not have to agree a partnership in advance. Their organic video can become part of a paid campaign if it semantically fits the Custom Sponsorships matching.
For a creator who consistently publishes on a single topic, a new passive layer of monetisation opens up on top of Custom Sponsorships AI matching. Paid affiliate offers will suddenly pile onto archive content. For a creator who builds a brand as a personal choice, that means losing control. AI decides which brand their video is grafted onto. Contractually it is a murky field, where YouTube has not yet provided a clear opt-out mode.
To support its argument, YouTube says that viewers who see creators talk about a product are 13× more likely to search for the brand and 5× more likely to buy. Coach reports a 60% jump in Gen Z brand awareness, a sixfold increase in consideration and steady acquisition growth in a single quarter.
Affiliate Boost moves monetisation decisions to YouTube
The second novelty, Affiliate Partnerships Boost. The programme amplifies organic videos with tagged products through YouTube Shopping affiliate links. An algorithm with a budget enters the decision about promotion. YouTube sees that a video converts, and pushes it into the feed.
For creators with a working affiliate catalogue, this is a subsidy. For top creators with negotiated brand deals, it is pressure to renegotiate, if an organic boost earns the brand more than the agreed partnership.
A parallel announcement shows where all this is heading. The integration of Costco and Dollar General data into Display & Video 360, in the same package, moves YouTube’s advertising stack towards retail media networks. Affiliate Boost is a creator layer on top of the same commerce funnel.
Buy with Google Pay removes the last barrier
Buy with Google Pay on CTV. The feature enables purchase in two clicks. Conversions from CTV have so far happened via mobile or desktop. Measurement will be simpler, attribution fits into a single session, and ROAS lines up with YouTube on desktop. CTV creatives will start competing for the same budget as the social feed.
For creators on the television screen, the price per slot will be recalculated as CPA against the Custom Sponsorships stack, instead of survey-based “brand uplift”.
Prestige, sport and docuseries replace haul videos
So that brands believe there is something to buy on YouTube, Brandcast showcased a slate of new formats. Trevor Noah World Tour is a prestige travel format wrapped in a comedy world tour. Alex Cooper is bringing Before the Steps, a docuseries following celebrities ahead of the Met Gala (starting spring 2027). Kareem Rahma is shooting Keep the Meter Running, an interview series in New York taxis that launches on the very evening of Brandcast.
Quen Blackwell is coming with Feeding Starving Celebrities 2.0 in autumn 2026. Cleo Abram is shooting another season of HUGE* If True, this time from Antarctica. Johnny Harris is building a six-part cinematic docuseries, The Human Element, also in autumn 2026.
YouTube is betting on the prestige format and sports rights. Erling Haaland’s docuseries Road to World Cup is due in June 2026. Pros vs YouTubers from Jesser arrives in 2027. Dude Perfect will bring a second season of Squad Games, also in 2027. The line between creator and TV show is blurring.
Michael Ruffolo, Head of Creator & Influencer Partnerships at Shopify, wrote on LinkedIn after Brandcast about the telling contrast he saw from the hall. Jesser, with almost forty million subscribers, drew polite applause, while Dwyane Wade, who has a fraction of that audience on YouTube, got the hall on its feet. The advertising world, he says, still defaults to legacy fame, even though the attention graph moved elsewhere long ago. Bruna Vilela, creative producer for YouTube and podcast formats, responded in a comment that one name looks great on a billboard, but the other will actually make someone stop scrolling at eleven at night and click.
Gemini’s GEO was the real sleeper hit of Brandcast
The sleeper hit of Brandcast was Gemini’s GEO, according to Ruffolo. Generative Engine Optimisation is a new version of SEO for an era when users do not search for answers by hand, but get them from an AI assistant. Gemini, ChatGPT, Perplexity, Claude. These models cite creators’ content: reviews, tutorials, comparison videos. What has been optimised for Google search over the last ten years is now being optimised so that an LLM treats it as a trustworthy source.
Ruffolo adds on LinkedIn that if creators’ organic content is to play a central role in how AI systems rank, search and recommend information, a creator strategy stops being only about sponsorship. Creator content becomes what people and AI both use to decide what to buy, where to travel and whom to trust.
A brand buys a creator’s video so that Gemini cites it in its answer to the user. Custom Sponsorships decide the advertising layer; AI decides which creator content it cites as the answer.
AI pulls content according to relevance and citation quality. As Pavlína Louženská writes in the TrendBrews trend report for 2026, curators are the new influencers, “because taste is now basic equipment”. Curators do the choosing. In this layer, taste gains measurable weight.
YouTube now negotiates for creators with AI assistants
Custom Sponsorships, however, run into EU regulation. Article 50 of the EU AI Act applies to all AI-mediated advertising in the EU from 2 August 2026. Every spot in which an algorithm dynamically selects a creator’s clip for a brand campaign must carry a visible disclosure and machine-readable metadata. Penalties reach up to 3% of global turnover or €15 million, whichever is higher. For brands in the EU, this means that Custom Sponsorships in their current form need an extra legal layer.
YouTube has become a platform that negotiates for creators with AI assistants. Custom Sponsorships, Affiliate Boost and Buy with Google Pay form a single stack, in which the algorithm decides which creator is shown where and to whom. Being cited by a machine is becoming a condition of a brand deal.
