Twitch Initiates Alpha Testing for Vertical Video Streams, Challenging TikTok and Reels

Livestreaming giant Twitch, an Amazon subsidiary, has officially begun alpha testing its highly anticipated vertical video format. This strategic move, first announced at TwitchCon earlier this year, sees initial tests going live with a select group of streamers, signaling a major platform evolution aimed at competing directly with short-form video powerhouses like TikTok, Instagram Reels, and YouTube Shorts.
Findings from market intelligence provider AppSensa reveal that recent Twitch builds contain references to these vertical video tests, including details on new features such as a dedicated vertical theater mode and the ability to seamlessly switch between Twitch’s classic and new vertical video formats. Users encountering the feature are greeted with educational prompts, confirming its experimental status.
While the current implementation is limited to a small number of channels, Twitch has confirmed that these tests are underway and are slated to expand to a broader user base later in the year. This initiative marks a significant step for Twitch, as it seeks to diversify its content offerings and capture a larger share of the rapidly growing vertical content market.
