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.
