Fox has agreed to acquire Roku in a deal valued at approximately $22 billion, a transaction that would combine Fox's $16.3B revenue linear broadcast and sports media business with Roku's fast-growing connected-TV operating system. Roku reported FY2025 revenue of $4.7B growing 15.2% YoY with a 43.8% gross margin, though net margin remains thin at 1.9%, suggesting Fox sees strategic platform value well beyond current earnings power. The combined entity would rank as the third-largest television company in the U.S., giving Fox direct ownership of a dominant streaming distribution layer.

The immediate setup is a classic merger arb: ROKU shares should trade toward the implied deal price, with the spread reflecting regulatory risk under current antitrust scrutiny of large media combinations. Watchers should monitor whether DOJ or FCC flags competitive concerns given Fox's ownership of broadcast licenses and Roku's gatekeeper position in connected-TV distribution — that regulatory overhang is the primary variable determining how wide the arb spread stays.
