Twitch ships native vertical mobile — the format change has its hardware moment

Native 9:16 ingestion, dual-output overlays, and a real chat experience on portrait. The TikTok-Twitch convergence is finally engineered correctly.

Twitch shipped native vertical mobile streaming on March 30. The new ingestion path accepts pure 9:16 sources, the chat experience is finally portrait-native rather than letterboxed, and the discovery feed surfaces vertical streams in a separate carousel from the main directory.

What this means for the streaming gear market: a new build category. The vertical-only stream rig wants a tall ring light, a phone gimbal mount that adjusts on the fly, and a compact mic. Elgato, Shure and Razer all shipped products into this niche in the last 60 days.
