Social media statistics 2026: users by platform, scheduling and MCP

What is the biggest social media platform?

By monthly active users, Facebook is the largest platform in posterly's platform guides at 3.07B, followed by Instagram (3.0B) and YouTube (2.5B+). The figures come from different sources and dates, so treat close neighbours as a tie rather than a ranking.

Not ranked because the guide gives a range rather than one figure: Mastodon (Under 1M).

Only rows labelled monthly active users are ranked. Registered accounts, daily users and audience reach are shown in the tables below but are not comparable with them.

Frequently asked questions

Method and last updated

• Last updated: 30 September 2026, Asia/Dubai (UTC+4).
• Platforms: publish destinations returned by product platform listing with planned networks excluded. Google Drive, Canva and local files are not counted in the "18 platforms" claim.
• MCP tools and actions: post-consolidation surface from product tool counts (stdio versus hosted). Older pre-merge tool-name totals are obsolete for marketing.
• Posts published: count of posts rows where published_at is not null. One row is typically one destination publish, not a unique creative group. Scheduled, draft, paused and failed rows without a publish timestamp are excluded.
• Connected accounts: rows in social account connections. Workspaces: product workspace records. These are not the same as login users or subscription counts. Login-user and paid-plan counts are intentionally omitted from this page.
• Signup to first publish: median hours among the set of users who have at least one published post (n=60). Mean is not quoted (long tail). Negative deltas: none in this pull.
• Publish success: success / (success + failed) from publish logs in the trailing 90 days. Pipeline "started" and "skipped" outcomes are not in the success denominator.
• Platform tables: copied from the key numbers in each posterly platform guide, with the guide's own source, source link and last reviewed date. The reviewed date can be later than the dates of the sources cited. Nothing on those tables is calculated except the order of the monthly active user ranking.
• Industry sources: linked above with publication or field dates. Re-check primary URLs before quarterly refresh.
