Vertical Video in 2026: A Format That Stuck

Open your phone. Swipe up. The format is already there. Vertical video, shot tall for the screen it lives on, set to autoplay, designed to be discovered in seconds. The format moved from a niche feature to the dominant social ad surface in less than a decade, and 2026 is where attention and ad dollars meet on its terms.

Before getting into craft or scale, the case for vertical video itself needs to be clear. Three things point in the same direction: audience behavior has settled around short-form, the platform landscape spans 3 distinct surfaces, and ad spend is following both.

The Format Audiences Reach For

Vertical video is the format people choose when they pick up their phone. Pew Research puts Instagram at 50% reach among US adults and TikTok at 37%, with both climbing to 80% and 63% among adults under 30, respectively. TikTok adoption nearly doubled between 2021 and 2025, growing from 21% to 37% of US adults. YouTube Shorts now reaches 72% of YouTube users at least weekly.

The pattern holds across every age group. People scroll to watch, watch to discover, and respond best to quick, creator-led video that feels native to the way they hold their phones. That is the cultural pattern advertising has to meet.

Reels, TikTok, and YouTube Shorts

The vertical video landscape spans 3 distinct platforms, each with its own audience and creative grammar.

Instagram and Facebook Reels sit inside Meta’s social environment, with Reels appearing across both apps and shoppable formats already in place. Reach is broad, with Instagram especially strong among adults under 30.

TikTok is the platform that defined the format. Its Gen Z and Millennial concentration shapes what works in short-form creative, and sets the pattern the rest of the industry adopts. 

YouTube Shorts is the youngest of the three and already commands enormous scale. Daily Shorts views passed 200 billion in 2025, up from 70 billion in early 2024.

Choosing where to invest comes down to where your audience actually lives. Article 3 of the Vertical Video Playbook takes the comparison deeper.

Ad Dollars on the Move

Advertisers have shifted their budgets to align with their audience profile. BIA forecasts US local social ad spend climbing from $36.7B in 2025 to $42.6B in 2026, with more than 70% running through video formats and short-form on TikTok, Reels, and YouTube Shorts, pushing social video revenue past $30.2B. The growth curve continues. INMA, citing eMarketer and PwC forecasts, projects that 70% of display spend will shift to digital video by 2028, driving $146B in short-form video ad spend.

Spend trajectory validates the audience picture. Vertical video sits in the central growth lane through 2028 and beyond.

What Comes Next

Vertical video has earned its place. Audiences reach for it, platforms invest in it, and advertisers are chasing the attention. The opportunity in 2026 is real.

Capturing it takes craft, platform fluency, and a production approach that can keep up with 3 short-form feeds running at once. The question of execution is where the work begins.
