Fox just dropped $25 billion to buy Roku - in reaction, Fox stock ($FOXA) fell about 18% because of the hefty price tag, setting $4 billion of Fox's market cap on fire.
What Fox gets. Tubi has 100M monthly active users. Roku has 100M streaming households. Stack those together and you get the fourth biggest streaming platform with a 5.2% market share, overtaking Amazon Prime (3.8%), and just shy of Disney (number 3 at 5.3% market share incl. Hulu and ESPN ). But it still is quite a bit smaller than the market leaders with YouTube at 13.2% and Netflix at 8.3%. (All numbers Nielsen Gauge, March 2026).
Fox also gets Roku's OS, AdTech, and first-party audience data.
What Roku gets. Roku gets saving. Walmart ate Vizio, Amazon has Fire TV, Google has Android TV. Roku's independence was becoming a liability. Now it has a deep-pocketed parent, content to anchor The Roku Channel, and live sports baked right in.
The catch. Fox is borrowing $12 billion - that's a lot of debt for a company betting on ad revenue. And Roku's platform neutrality - the reason every streaming app plays nice with it - is now an open question. Will Netflix and Disney keep distributing through a Fox-owned OS?
For buyers. CTV advertising just got more consolidated. Expect greater audience reach, higher prices, fewer third-party streamers on Roku and more bundled Fox/Roku packages.
For AdTech vendors. Business will likely be as usual. Roku largely relies on Amazon (DSP), The Trade Desk and Yahoo (DSP) for advertising distribution, and Tubi does with several DSPs as well. Roku does have the OneView DSP (from the DataXu acquisition), and could theoretically ramp it up more to save payouts to partners. But it has de-emphasized OneView in the past, and the companies have said they are committed to an "open, partner-friendly platform" - for whatever that's worth. Always remember, one's skin is closer to one than one's shirt.
Overall, a smart deal with real execution risk. Watch the debt, the antitrust review, and whether Netflix and Disney pulls their apps.
