Netflix Ad Business Booms with Record Q3
Netflix reported strong Q3 2025 results driven by its advertising business, posting 17% year-over-year revenue growth to $11.5 billion and its best ad-sales quarter ever even as a surprise $619 million Brazilian tax charge produced an earnings miss and a stock dip. The company says its ad revenue is on track to double for a second consecutive year, aided by expanded programmatic buying on its in-house ad platform and major content hits (e.g., KPop Demon Hunters and a high-profile boxing event). Netflix is also experimenting with AI-driven ad formats (targeting dozens by 2026), expanding content deals (including exclusive video podcasts from Spotify), and launching new interactive living-room experiences. Co-CEO Ted Sarandos downplayed acquisition speculation, framing Netflix as primarily a builder rather than an acquirer.
Netflix is a major streaming platform; a strong ad-sales quarter and rapid ad-revenue growth materially affect CTV/streaming ad inventory, programmatic buys, and walled‑garden ad strategies—important for advertisers, agencies and ad tech vendors.

Netflix Doubled Ad Revenue in 2025, Sees $3B in 2026

Google/YouTube is rolling out shoppable connected-TV (CTV) ads via Display & Video 360 and Google’s Smart TV ecosystem, using Google Merchant Center feeds to create interactive carousels (QR-enabled) in non-skippable 15-second spots. Netflix reported advertising revenue grew 2.5x year-on-year, surpassing USD $1.5bn in 2025, underscoring rapid ad-monetisation scale as it pursues further growth in 2026 while its proposed Warner Bros. acquisition remains in focus.
