The news: Fox Corporation announced a definitive agreement to acquire Roku in a $22 billion cash-and-stock deal. The transaction blends Fox’s powerhouse live content (including sports, news, and entertainment) with Roku’s massive distribution network, creating the third-largest player in U.S. television by viewing share. The deal is expected to close in the first half of 2027, pending regulatory and shareholder approval.

Why it matters: Fox plans to combine The Roku Channel with Tubi, which Fox bought in 2020. This merger will effectively create the largest Free Ad-supported Streaming Television (FAST) platform on the market.

• The merged company will have access to more than 100 million worldwide streaming households; by 2030, The Roku Channel and Tubi are forecast to have a combined 214.2 million viewers (107.8 million and 106.6 million, respectively) per EMARKETER.

• Fox will absorb first-party viewer data and hardware-level identity tracking from RokuOS. This gives Fox sophisticated targeting capabilities that rival tech giants like Amazon and Google. Based on Omdia data, RokuOS owned 31% of market share for SmartTV shipment in 2025, however due to a shift in OS for Walmart's Onn smartTVs, RokuOS is projected to have only 13% market share in 2029.

The impact: Fox and Roku have emphasized that Roku will remain an "open, partner-friendly platform" for competing apps like Netflix, Disney+, and Max. But while competing apps will still live on the platform, Fox will control the underlying AI, discovery engine, and home screen real estate of Roku OS, enabling it to prioritize its own content in user interfaces. Roku OS gives Fox a direct pipeline to push cord-cutters back into the live ecosystem.

Implications for marketers: Previously, media buyers had to split budgets across separate Free Ad-supported Streaming Television (FAST) apps to get maximum reach. Advertisers could now get a centralized, massive inventory bucket capable of reaching budget-conscious streaming and cord-cutting audiences at scale.

Fox will bring Roku’s expertise with formats like shoppable marketing straight to live, high-impact inventory like the NFL, MLB, and breaking news. Marketers can run high-funnel, mass-reach commercials during a live football game while leveraging lower-funnel, interactive performance metrics powered by Roku OS data.

This move signals that simply owning great content is no longer enough to win the streaming wars. To survive, media companies must control the full tech stack; the interface, the data infrastructure, and the monetization engine.
