Video advertising on streaming video distributor Roku made strong gains in the fourth quarter -- higher than other digital/OTT competitors on average, according to the company.

“In 2025, video advertising on our platform grew faster year over year than the U.S. OTT and broader digital ad markets,” says the Roku shareholder news letter, referencing Standard Media Index fourth-quarter data for OTT ad revenues.

Roku did not offer financial details, but platform revenue for the company is a “proxy” of sorts for video ad business, says Brian Wieser, media analyst and founder of Madison and Wall.

For the quarter, platform revenue -- of which advertising is around 70% to 80% -- rose 18% to $1.2 billion, with gross profit for platform business up 15% to $646.7 million.

Wieser says excluding political advertising year-over-year results, “we estimate growth would have been several percentage points higher.”

Usage -- streaming hours -- climbed 15% on its platform to 145.6 billion hours, Roku said.

Per Nielsen, The Roku Channel says it is the number two free, ad-supported streaming platform in the U.S. -- second only to YouTube, with a 6.3% share of all ad-supported streaming in December 2025.

Fox Corp.'s free, ad-supported streaming platform Tubi recently said it had a 6.2% share of all ad-supported streaming in the fourth quarter.

Company wide, Roku revenue overall -- including device revenue -- was up 16% to $1.4 billion, with net income of $66 million, versus a $39.1 million net loss.

Adjusted cash flow (earnings before interest, taxes, depreciation and amortization) more than doubled to $169 million.
