Instagram tests horizontal video on CTV apps to rival YouTube ad revenue

Instagram’s shift to horizontal video marks a strategic departure from its native vertical-first identity to better align with the 16:9 orientation of living room screens. By incentivizing longer horizontal uploads, Meta is positioning Instagram as a viable lean-back entertainment platform rather than a short-form mobile utility. This moves the platform into direct competition with YouTube for CTV ad dollars, which are expected to represent over 40% of global video ad spend by 2030. Success depends on whether mobile-first creators will produce distinct, high-fidelity landscape content for the television app ecosystem. Investors should track creator adoption of 10-minute-plus horizontal uploads as a proxy for the app's CTV stickiness.

The push into horizontal CTV video follows a record-breaking financial period for Meta. According to Meta’s Q1 2026 earnings report from April 2026, the company generated $56.3 billion in total revenue, a 33% year-over-year increase, with family app advertising accounting for $55 billion of that total. During the same quarter, Meta’s family daily active users grew 4% to 3.56 billion, despite regional internet disruptions. Meta’s emphasis on video monetization is timely, as Omdia reported in May 2026 that Big Tech firms are expected to increasingly dominate the CTV landscape, with YouTube alone generating nearly $10 billion in revenue in early 2026.

Competitors are also evolving their television strategies. While YouTube remains the most-watched streaming platform on U.S. televisions—capturing 12.5% of total viewing time per Nielsen's May 2025 Gauge report—short-form rivals are diversifying. Per Kursiv Media (January 2026), TikTok has experimented with vertical-format microdramas through its PineDrama app to capture high-intent viewers, while Instagram separately launched a dedicated TV app for Reels in late 2025. This fragmentation is occurring as eMarketer projections from February 2026 indicate that U.S. CTV ad spending will hit $38 billion in 2026, growing twice as fast as the broader advertising market.

Internal Meta shifts suggest a re-prioritization of long-form video. Tessa Lyons, Instagram’s VP of Product, noted at the May 2026 Scalable Summit that vertical content alone is likely insufficient for television success. This is supported by data from Influencer Marketing Hub (2025) suggesting creators can earn significantly more from content exceeding 10 minutes. As Meta’s capital expenditures are projected to reach $125 billion to $145 billion in 2026, the company is increasingly using AI to facilitate communal viewing through features like auto-translation and dubbing, aimed at making localized creator content globally accessible on larger screens.
