YouTube ad growth slows as TikTok and Netflix capture performance budgets
WARC Media reports that YouTube's advertising revenue reached $40.4 billion in 2025, though year-on-year growth is decelerating due to competition from TikTok and Netflix. The platform is increasingly focusing on connected TV and podcast inventory to capture larger advertising budgets despite the shifting competitive landscape.
Key Takeaways
- YouTube's total revenue, including Premium subscriptions, surpassed $60 billion for the first time in 2025.
- Connected TV accounts for 45% of U.S. watch time, with average session lengths exceeding 45 minutes.
- TikTok's ad revenue is projected to overtake YouTube's by 2028 if current growth trajectories hold.
- Shorts monetization is accelerating, with revenue-per-watch-hour in the U.S. now exceeding traditional in-stream formats.
- Monthly podcast viewers on YouTube via TV screens rose 70% year-on-year to 700 million hours.
Why It Matters
The deceleration signals a fundamental shift in how marketers allocate digital video budgets. While YouTube remains the dominant reach vehicle with 2.6 billion users, it is losing ground in lower-funnel performance marketing to TikTok's social commerce integration. Simultaneously, Netflix's ad-supported tier is increasingly competing for the high-end brand awareness dollars traditionally reserved for premium television. YouTube's strategic response—pivoting toward Connected TV and long-form podcast inventory—aims to recapture larger television budgets where it maintains high completion rates and session depth. To maintain its lead, YouTube must bridge the gap between high viewership and direct-response outcomes. Watch for whether YouTube's growing visibility within large language models translates into a durable competitive advantage over Reddit and TikTok in organic search discovery.
Additional Context
The competitive shift coincides with Netflix significantly scaling its advertising infrastructure. Per Ubos.tech in January 2026, Netflix's ad-supported tier reached 94 million monthly active users by mid-2025, with ad revenue more than doubling to $1.5 billion. Netflix executives have expressed confidence that ad revenue will double again to $3 billion in 2026, supported by new formats like AI-generated product placements and interactive video ads. DemandSage reported in May 2026 that roughly 60% of new Netflix subscribers in ad-supported markets now opt for the lower-priced plan, creating a consistent influx of premium inventory for buyers. Podcast consumption is also increasingly migrating to the living room, a trend YouTube appears to be winning. Per Edison Research in July 2026, YouTube officially surpassed Spotify as the most-used podcast platform in the United Kingdom, mirroring a shift that occurred in the U.S. two years prior. Signal Hill Insights further noted in May 2026 that smart TVs have become the second most-used device for podcast consumption among UK users aged 18-34. This behavior reinforces YouTube's dominance in the video-podcast hybrid space, where it currently holds an 81% share of global views according to Zebracat data from June 2026. Meanwhile, TikTok's direct impact on performance marketing continues to intensify through its commerce-first ecosystem. Per Mordor Intelligence in 2026, the global social commerce market is estimated at $2.1 trillion, with TikTok Shop doubling its global revenue in 2025 to reach $64 billion. As eMarketer reported in February 2026, U.S. users aged 18-34 now spend an average of 68 minutes daily on TikTok, driven by live commerce and episodic content. This high dwell time is a direct threat to YouTube's traditional role as the primary destination for long-form creator content and discovery.
