Fox buys Roku for $22B, forging a FAST streaming giant
The deal merges Tubi and The Roku Channel into a single operator that controls more than half of the US FAST market.

Fox Corporation has agreed to acquire Roku for 22 billion dollars in a deal that instantly reshapes the free ad supported streaming landscape. By folding Roku's device and platform business into its own Tubi operation, Fox creates a single ad supported giant that, according to eMarketer, will control more than half of the FAST market in the United States. For an industry that has spent years fragmenting audience attention across dozens of ad supported channels, this transaction concentrates reach, data, and pricing power in one place almost overnight.
Roku built its business as the operating system that powers a huge share of connected televisions sold in the United States, giving it a rare vantage point: it sits between viewers, content, and advertisers on nearly every smart TV screen. The Roku Channel grew out of that distribution advantage into one of the largest FAST services in the country, paired with an ad tech stack and audience data products that agencies have relied on for cross publisher planning. Fox, meanwhile, built Tubi into a major ad supported streaming service sitting alongside its broadcast networks, cable channels, and sports programming.
What Fox is buying is not simply another content library or streaming app. This is a vertical merger that puts the platform layer, the device and operating system layer, and ad supported programming under a single corporate roof. Roku's hardware and OS dominance in connected TV distribution now sits directly inside Fox, alongside Roku's ad tech and audience data and Fox's own content and Tubi's existing scale. Few single transactions have combined that many layers of the CTV stack at once.
Consolidating FAST Inventory
For marketers, the immediate question is inventory concentration. Tubi and The Roku Channel have operated as competing FAST destinations with separate ad stacks, separate measurement partners, and separate deal terms, which gave buyers leverage to shop pricing and negotiate independently across both. Under Fox ownership, buyers should expect consolidation of ad sales teams, unified data products, and likely pressure toward bundled buys spanning both platforms rather than standalone deals. eMarketer's coverage frames this explicitly as a redrawing of power in CTV and ad supported television, not an incremental tuck in acquisition, and that framing matters because it signals structural change rather than a minor product integration.
Leverage In Upfront Talks
The deal also reshapes leverage in upfront and programmatic negotiations. Roku has functioned as a key independent measurement and device data source that agencies used to plan and validate reach across multiple publishers, in part because it was not owned by any single content company. If that data and inventory now sits primarily inside a Fox owned stack with majority FAST share, agencies lose some of that independent reference point. Competing platforms, including Amazon's Freevee successor efforts, Paramount, and Peacock, will face a larger, more concentrated rival when courting the same advertising budgets, which could push them toward their own consolidation or partnership moves to keep pace.
What Marketers Should Do
Why it matters: marketing teams should reassess CTV media plans now, since Fox's combined Tubi and Roku Channel footprint changes the calculus on reach, frequency, and pricing power across the FAST category. Media buyers should ask their current Roku and Tubi representatives how integration will affect existing deal terms, rate cards, and measurement access in the near term, rather than waiting for the deal to close. Treat this acquisition as a signal to diversify FAST partners and maintain relationships across other ad supported platforms, rather than assume the status quo inventory landscape and pricing dynamics will hold steady through the transition.
