Streaming consolidates: the $21 billion ad business and Fox's Roku bet

The combined Paramount Skydance and Warner Bros. Discovery ad business is projected to reach $19 billion to $21.6 billion in 2027, up from $18.5 billion to $20.7 billion this year, with streaming growing 20 to 35 percent a year to $8 billion to $9.5 billion while linear ad revenue declines 5 to 8 percent to $11 billion to $12.1 billion, according to analyst estimates cited by MediaPost. Fox and Roku shareholders approved Fox's $22 billion acquisition of Roku, expected to close in the first half of 2027 pending Justice Department clearance, which Variety reported combines Fox's Tubi with the Roku Channel into a far larger free, ad-supported streaming footprint. AdExchanger separately reported Meta is now selling ad slots TV-style, while MediaPost asked whether viewers will tolerate the additional ad minutes streamers are loading.

The crux

The streaming ad market is scaling fast enough to absorb the decline of linear, but only for the sellers with both scale and ad tech, which is why Fox is paying $22 billion for a platform rather than renting one.

Sell-side read

Inventory is consolidating into a handful of scaled sellers, which shifts negotiating power and makes the agentic and programmatic pipes those sellers build, not the shows themselves, the thing publishers and buyers now compete on. Midterm political spend alone is projected to add roughly $300 million to the combined Skydance business.

Watch

The DOJ's review of the Fox-Roku deal and the 2027 upfront, where the merged and consolidated sellers will price a far more automated market.
