The 10 most-cited stats

Community growth

Online communities are no longer a side channel: Reddit alone added more daily users in a single quarter than most apps have in their entire user base, and the software market built to run these communities is growing faster than most enterprise software categories.

Reddit's daily active user base (DAUq) grew 19% year-over-year to 121.4 million in Q4 2025, ahead of the roughly 120 million Wall Street had expected (Reddit Inc., Q4 2025 results).

International users now account for 57% of Reddit's daily actives, with international DAUq up 28% year-over-year to 68.9 million versus 9% U.S. growth (Reddit Inc., Q4 2025).

Reddit's U.S. daily actives still grew 9% year-over-year, reaching 52.5 million in Q4 2025 (Reddit Inc., Q4 2025).

Reddit's weekly active user base (WAUq) reached 471.6 million in the same quarter (Reddit Inc., Q4 2025).

Discord's monthly active user base is estimated at 200 to 260 million as of 2025, since Discord does not publish an audited MAU figure (industry trackers, 2025).

The global online community platform market is valued at $1.8 billion in 2025 and projected to reach $5.2 billion by 2034, a 12.5% CAGR (Verified Market Research, 2025).

The community-led growth platform market reached $1.73 billion in 2024 and is forecast to grow at a 19.4% CAGR through 2033 (Dataintelo, 2025).

94% of community professionals say their community is at least "somewhat successful," though only 17% call it "extremely successful" (CMX Community Industry Report, 2025).

Customer Success now owns community strategy at 19% of organizations, up from 8% in 2022, while marketing still leads at 31% (CMX Community Industry Report, 2025).

Together, these numbers point to a market consolidating around dedicated community infrastructure rather than general-purpose social features bolted onto an existing product.

Engagement

Getting users into a community is one problem; keeping them active is another, and the data shows engagement depends more on structure, such as mentoring, events, and live formats, than on raw membership numbers.

Communities that build in volunteering and mentoring programs see 2.4x more logins than those that don't, based on a benchmark of roughly 1,500 associations (Higher Logic Association Community Benchmark Report, 2025).

Those same communities generate nearly 2x more discussion threads than communities without structured programs (Higher Logic, 2025).

Zoom remains the top platform for community events, used by 65% of community teams, while Bevy adoption nearly doubled to 19% from 11% in 2023 (CMX Community Industry Report, 2025).

Google Meet usage for community events rose to 22% in 2025, up from just 10% two years earlier (CMX Community Industry Report, 2025).

Only 15% of association community members actively participate within any given 120-day window (Higher Logic Association Community Benchmark Report, 2025).

The common thread across this section is structure: communities with clear programming, whether events, mentoring, or a live cadence, consistently outperform communities that rely on membership size alone.

Retention impact

Retention is where community infrastructure earns its budget: apps and brands that add genuine peer-to-peer features consistently report retention gains that outpace push notifications and email alone.

Apps that add community or social features see retention rise by around 37% on average (Business of Apps, 2025).

Well-implemented social features such as forums, chat, and leaderboards are linked to retention rates 30% to 50% above category average (Business of Apps, 2025).

Adding features like forums or in-app chat can boost retention by as much as 2.7x in apps that implement them well (Business of Apps, 2025).

First-year member renewal sits at a median of 75%, nine points below the 84% overall renewal rate across associations (MGI 2025 Membership Marketing Benchmarking Report).

78% of organizations reported an average-or-better first-year renewal rate compared to the previous year (MGI, 2025).

Communities with volunteering and mentoring programs see nearly 2x more contributors, widening the base of members most likely to renew (Higher Logic, 2025).

None of these figures describe something automatic. They describe what happens when community features are built with real staffing, moderation, and program design behind them, not what happens by default.

Monetization

Community and commerce are converging fast, especially inside social platforms, and organizations that treat community as a revenue line rather than a support cost are expanding that line every year.

U.S. social commerce sales reached $87 billion in 2025, up 21.5% year-over-year (eMarketer, 2025).

U.S. social commerce sales are projected to surpass $100 billion for the first time in 2026, an 18% year-over-year jump (eMarketer, 2026 forecast).

TikTok Shop's U.S. sales grew 108% in 2025 to reach $15.8 billion, following 400% growth in 2024 (eMarketer, 2025).

63% of associations expect non-dues, community-driven revenue to increase in the coming year (MGI 2025 Association Outlook Report).

61% of associations rank non-dues revenue generation as their top strategic challenge, the third year running (Association Benchmarking Report, 2025).

The pattern holds across both consumer social commerce and B2B association revenue: community-adjacent income is growing faster than the baseline it sits inside, even as most organizations still call it hard to generate.

Moderation and trust

Trust is the resource that makes every other statistic on this page possible: as user-generated content scales, so does the infrastructure required to keep it safe, credible, and free of manipulation.

The global content moderation services market was valued at $9.7 billion in 2023 and is projected to reach $13.4 billion by 2026, roughly a 13% CAGR (Grand View Research, 2024).

Yelp filtered out nearly 500,000 suspected AI-generated reviews globally in 2025 (Yelp Trust & Safety Report, 2025).

Yelp closed more than 1.3 million user accounts for Terms of Service violations in 2025, a 138% increase from 2024 (Yelp Trust & Safety Report, 2025).

Yelp's reports to other platforms about suspicious review activity rose 45% year-over-year, and partner platforms acted on 60% of them (Yelp Trust & Safety Report, 2025).

Yelp users contributed 22 million reviews in 2025 alone, every one screened by the same detection systems (Yelp Trust & Safety Report, 2025).

82% of consumers say they have abandoned a brand over privacy or trust concerns, and no digital sector cleared 50% consumer trust in 2025 (Thales Digital Trust Index, 2025).

Meta's AI systems applied moderation or context labels to roughly 180 million pieces of content across Facebook and Instagram in a recent six-month window, while enforcement mistakes fell 50% between Q4 2024 and Q1 2025 (Meta, cited 2025).

Large enterprises accounted for 61% of the content moderation services market's 2025 value, reflecting where compliance and brand-safety spending concentrates (market analysis, 2025).

Every one of these figures reflects investment, not luck. Trust and safety outcomes scale with the resources a platform or brand puts behind them, which is exactly why moderation now shows up as its own budget line rather than a shared cost with support.

AI in communities

AI has moved from an experimental add-on to the default tool in a community manager's stack within about a year, reshaping how communities are moderated and how users expect to be engaged.

93% of community professionals now use AI tools in their day-to-day work, up from 81% the year before (CMX Community Industry Report, 2025).

88% of organizations are using AI in at least one business function, and 65% regularly use generative AI (McKinsey State of AI, November 2025).

AI content-moderation systems now reach roughly 94% accuracy in English-language content, letting human moderators focus on escalated edge cases (industry analysis, 2025).

TikTok's automated systems detected and labeled 35% to 45% of AI-made content on the platform by late 2025, up from about 18% in early 2024 (industry analysis, 2025).

The AI-specific content-moderation software segment is projected to grow from $3.07 billion in 2025 to $3.88 billion in 2026, a 26.6% CAGR (market analysis, 2025).

72% of U.S. teens have tried an AI companion app, and 52% use one regularly (TechCrunch survey, 2025).

Even so, 86% of leaders say their organizations are not fully prepared to adopt AI in day-to-day operations, a gap worth watching as AI tools spread through community teams (McKinsey State of AI, November 2025).

FAQ

How many people participate in online communities?

Participation scale varies by platform: Reddit reported 121.4 million daily active users and 471.6 million weekly active users in Q4 2025, while Discord is estimated at 200 to 260 million monthly active users (Reddit Inc., 2026; industry trackers, 2025). Within branded and association communities specifically, day-to-day participation is much shallower, with only about 15% of members active in any given 120-day window (Higher Logic, 2024), which is why community teams increasingly design for a smaller, highly engaged core rather than raw membership size.

Do online communities improve retention?

The available data points that direction: apps that add community or social features see retention rise by around 37% on average, and well-implemented features like forums or in-app chat can boost retention by as much as 2.7x (Business of Apps, 2025). Association research shows a similar pattern, where first-year member renewal sits nine points below the overall renewal rate, which suggests that early engagement inside a community strongly influences whether that gap closes (MGI 2025 Membership Marketing Benchmarking Report). Results depend on how the community is built, moderated, and staffed, so these figures describe a pattern, not a promise.

How fast is the community software market growing?

The global online community platform market was valued at $1.8 billion in 2025 and is projected to reach $5.2 billion by 2034, a 12.5% compound annual growth rate (Verified Market Research, 2025). The community-led growth platform segment is growing even faster, from $1.73 billion in 2024 at a 19.4% CAGR through 2033 (Dataintelo, 2025), reflecting how much infrastructure investment is shifting toward community as its own category rather than a bolt-on feature.
