Which social media platform is the biggest in the US in 2026?
Instagram has the largest measured US audience with approximately 145M people showing active interest over the trailing 12 months.
Are these monthly active users?
No. Monthly active users are self-reported by the platforms, defined differently by each and usually published globally rather than per country. This is an independent measure of people showing active interest in the platform within one market.
Why is the age split the important column here?
Because platform audiences differ far more by age than by size, and the age gap between the largest platforms is wide enough to decide a media plan on its own.
Does this include messaging apps?
Yes, where they are classified as social platforms and have measurable US demand. Messaging services frequently rank higher than their advertising inventory would suggest.
How often is the ranking refreshed?
Weekly, from the latest search-behavior data.
