TikTok maintains its position as the dominant short-video platform with 121 million monthly active users, while LinkedIn has emerged as the fastest-growing platform in 2026 with a 14.2% increase in users. The social commerce sector has exploded to $82.3 billion in revenue, driven by in-app purchasing features across Instagram, TikTok, and Pinterest.
