Free Streaming Becomes Fox's Main Stage: Tubi, the World Cup Hub and the AdStudio–Fan OS Stack Anchor the 2026 Pitch

A 100M-MAU Tubi takes a solo upfront slot. Fox AdStudio, launched on April 23, binds Tubi, news and sports into one advertising graph. The FIFA World Cup FOX Hub becomes the flagship activation surface.

Fox Corporation has moved the gravitational center of its advertising business onto Tubi, its free ad-supported streaming service. At its 2026 upfront, Tubi took the front of the stage, and the company's new advertising operating system — Fox AdStudio, paired with Fox Fan OS — was built explicitly to fuse Tubi with news, sports and entertainment into a single audience graph.

The FIFA World Cup, which kicks off on June 11, sits on top of that stack as the flagship activation surface: a free, login-free Hub on Tubi that the company now treats as a proof-of-concept for how live events, AI-driven contextual ad infrastructure and a 100-million-MAU free service can compound into a performance-grade business.

The structural backdrop is the steady erosion of cable. S&P Global's Kagan projects that subscribers across the three largest U.S. cable news outlets will fall another 7% to 9% between the end of 2024 and the end of 2026.

As cable thins, reach fragments, and advertisers have begun treating measurable outcomes and incremental reach as the new currency of television. A free, ad-supported streamer that gathers tens of millions of viewers without a paywall converts that currency into revenue without friction. That is why Tubi — not Fox One, the company's subscription streamer — took the central seat at the upfront.

Tubi's solo slot: 100M MAU, 91% incremental reach, double-digit category lifts

Anjali Sud, CEO of Tubi, took the stage to argue that Tubi has reached the scale to anchor an upfront pitch by itself. The numbers Fox put on the board:

• 100 million monthly active users; more than 10 billion hours watched annually
• Fourth among streamers for reach into high-income cord-cutter audiences, ahead of Disney+ and Paramount
• 91% incremental reach on identical campaigns versus linear TV, per third-party measurement
• Category-level ad lifts: retail +21%, QSR +37%, auto +25%, and roughly 4:1 ROAS in CPG
• New ad formats including pause-to-participate units and shoppable in-scene placements

These figures position Tubi not as an experimental sandbox but as a primary buy. The complement is structural: while Fox One uses live sports and news to anchor a paid subscription base, Tubi monetizes the same Fox content and IP a second time through advertising. Subscription and ad-supported, paid and free, sit on a shared audience graph and reinforce each other — and that complementary structure was the through-line of Fox's upfront.

The FIFA World Cup FOX Hub: Tubi's flagship activation

On May 18, Tubi placed the FIFA World Cup FOX Hub at the top of its homepage. It is not a single match-streaming page; it is a curated, time-sensitive destination that reshapes itself before, during and after the tournament.

Live windows, cut-downs, highlights, a 24/7 feed, original documentaries, creator content and classic library titles are all routed through one navigation path. The pitch is continuity — fans, in Tubi's framing, should never lose the thread.

The CTV implementation reinforces that argument. The Hub is pinned into the top navigation strip on the connected-TV home, and a single yellow "Explore" CTA opens the curated rows underneath. The friction normally introduced by login walls and subscription gates is simply absent: from cold open to live match, the path is direct. That is the free, ad-supported model's structural advantage, surfaced as product design.

Live 4K coverage on Tubi covers the opening ceremony and two matches: Mexico vs. South Africa on June 11, and the U.S. Men's National Team vs. Paraguay on June 12. The remaining matches stream across Fox's broader stack — 70 on Fox broadcast, 34 on FS1, and all 104 on Fox One. Tubi carries highlights, replays, and a 24/7 channel of best-of plays alongside FOX Sports' digital originals.

The originals lineup is built to drive both acquisition and retention. ‘Destination World Cup 2026’ follows the USMNT's Weston McKennie, Spain's Marc Cucurella and Wales' Harry Wilson through their pre-tournament arcs. ‘The Other Football,’ a weekly vodcast with NFL veterans Rob Gronkowski and Jameis Winston, takes a comedy angle — two American football stars learning soccer in public.

The creator slate stretches further: ‘Deestroying the Pitch,’ a 1v1 challenge series with YouTube creator Deestroying featuring fans from host cities; ‘Jesser's Ultimate Kick Off,’ a Jesse Riedel-led challenge format exclusive to Tubi; and talkSPORT's ‘How to Win the World Cup,’ where comedian Matt Forde hosts past champions including Emmanuel Petit, Kléberson, Stuart Pearce and Brad Friedel.

The premium library adds the BBC comedy ‘Twenty Twenty Six’ with Hugh Bonneville, the FOX retrospective ‘Summer of '94,’ and ‘Alexi Lalas' State of the Union’ for ongoing match analysis.

"The Hub is Tubi's contribution to that legacy: a free destination designed for a seamless fan experience, where viewers can easily navigate from live coverage and highlights to creator commentary, player interviews, and expert predictions," said Deirdre Hesseldieck, Senior Vice President of Product at Tubi, in the launch statement. The framing matters: ad-supported streaming is being positioned not as fragmented spot inventory but as a stage that absorbs the entire fan journey around a marquee live event.

Fox AdStudio: an audience graph designed to unify the portfolio

The reason Tubi can headline the pitch is that Fox AdStudio, which launched on April 23, gathers Fox's entire portfolio into one advertising graph. Fox introduced the platform alongside a new brand positioning — ‘passion into performance’ — designed to reframe the conversation from inventory to outcomes.

In an ADWEEK interview, Jeff Collins, Fox's ad sales chief, made the strategic case directly: the Fox News audience is distinct from the Tubi audience, and both are distinct from the entertainment and sports audiences. The point is complementarity. Bundle the four, and the result is large incremental reach paired with strong campaign performance — an effect Fox says it has seen "in pockets" and is now productizing at scale and at efficiency for advertisers.

Stephano Kim, Fox's chief strategy and operations officer for ad sales, described AdStudio as a three-layer architecture: (1) a Fox audience graph carrying real-time contextual, behavioral and identity signals; (2) a central intelligence layer that uses LLMs to combine knowledge of Fox's platforms with historical campaign performance; and (3) an automation layer that runs always-on measurement and reporting.

Delivery is buyer-shaped. Advertisers can plug AdStudio into their existing platforms, or work through a Fox-supplied interface — Kim's principle is that Fox's data, media and audiences should sit "where buyers transact today" rather than forcing a new workflow.

Agentic media planning and buying is the next layer. Kim said Fox is already in conversations with multiple agencies, large platforms and direct advertisers about how each side wants to plan and trade with AI agents. Collins framed the move as continuous rather than disruptive: given the platform Fox has built over the past year, the step into agentic execution is not a long one. The substantive shift is in the sales conversation — moving past the 30-second spot to ask how to harness a moment like the World Cup as a campaign creative platform.

Fox Fan OS: AI inference at the second, wired into the ad graph

At the upfront, CTO Melody Hildebrandt positioned Fox Fan OS as the higher-order operating system that sits above AdStudio. She defined it as an agentic, AI-native media OS with two surfaces: Fox Fan Studio on the consumer side and Fox AdStudio on the advertiser side.

The technical core is the way video is processed. Fox runs real-time AI inference against its raw video at the second level, extracting topic, talent, mood and "vibe," then cross-references that signal against performance data. The output is a continuous read on what is working with fans — usable in both content programming and advertising at the same time. For advertisers, the resulting stack offers a unified audience graph, scene-level contextual targeting, full-funnel measurement across more than 20 data partners, and direct integration with brands' own AI agents.

Fox says more than 1,000 campaigns have already been measured through AdStudio, with double-digit lifts on offline outcomes including in-store visits and purchase. In a market shaped by NBCUniversal's and Disney's outcome-and-AI narratives, this is Fox's bid to join that conversation without compromising its stated position of not chasing scale for its own sake.

Fox One's complement: sports fans staying for news

The data emerging from Fox One — the paid streamer — backs the Tubi-led narrative rather than competing with it. Fox One launched last fall around the NFL season, and internally Fox expected activity to soften once football wrapped. The actual pattern broke that assumption: viewers who arrived for sports stayed for news.

On Fox's most recent earnings call, CEO Lachlan Murdoch told investors that more than half of Fox One viewership in the fiscal third quarter came from news. Pete Distad, CEO of Fox's streaming operations, added more granular detail: a typical Fox One news viewer returns about 3.5 times per week and watches more than 10 hours of Fox News Channel. The average Fox One subscriber skews younger than the traditional cable customer, though older than the mobile-and-social-first Gen Alpha cohort.

The product is being reshaped around that behavior. On mobile, Fox One has rolled out topic-based discovery — instead of asking users to scrub through hours of linear news to find a segment, the service groups content by interest into short, navigable units. An "Ask Fox" feature lets users describe what they want and surfaces a tailored content guide in response. Fox is also planning to migrate the multi-view and real-time data interactions it is building for World Cup coverage onto future news events, starting with the U.S. midterms.

Fox News' digital footprint underpins the strategy. The network averages 3.1 million weekday primetime viewers — ahead of NBC; FoxNews.com pulls 143 million monthly unique visitors; and Fox News has accumulated 4.5 billion YouTube views over the past year. The audience is no longer cable-defined. Across Tubi (free) and Fox One (paid), Fox is assembling an integrated viewing structure that runs news, sports and entertainment through one ad graph.

Implications for the Korean media industry

The Fox playbook makes a single argument: free ad-supported streaming, live events and AI-driven ad infrastructure do not generate advertiser pull as independent assets. They generate it when bundled. In a market where cable decline is structural, simply adding another OTT brand will not shift the advertising balance.

Three points sharpen the read for the Korean market. First, in K-content global distribution, a dual structure — paid subscription plus FAST — is hardening into a default, and the pricing leverage shows up when both channels feed the same advertiser graph. Second, the combination of live events (sports, news, awards) with ad-supported streaming is becoming the center of gravity for new ad inventory, which means second-level metadata extraction and scene-level contextual targeting are emerging as a competitive axis Korean operators have not yet had to compete on. Third, the sales motion itself is migrating from 30-second-spot transactions to agentic planning and buying conversations — and that migration will force both media reps and platforms in Korea to rebalance their technical and commercial talent.

The first U.S.-hosted World Cup in 30 years is the credibility test for Fox's digital transformation. The question Korean operators face is structurally similar: as the next wave of global sports and cultural events arrives, in what order will they layer them onto their own live, FAST and AI-ad stack — and at what point in that sequence will revenue and viewing data both come back?
