There was no press release and no keynote. One morning last week, an app called Forum appeared on Apple’s App Store, and by Friday it had a name in Silicon Valley: Meta’s quiet answer to Reddit. The company confirmed it was testing the product, and the market did the rest.
The app is a standalone version of Facebook Groups, wrapped in a Reddit-style interface: threaded discussions, sorted feeds, and communities organized by interest. It launched as a test on iOS, requires a Facebook account, and posts made in Forum appear in users’ groups on the main app. Meta describes Forum as “a dedicated space built for deeper discussions, real answers and communities you care about.”
The reaction came quickly. Reddit shares fell almost 6 percent on Friday, the day the app’s existence became widely known, on concern that Meta could create an alternative venue for the discussions that have made Reddit valuable. Truist analysts wrote in a note that the app is “an attempt by the company to compete against Reddit as an online forum for public discourse” and represents a new threat, warning of a gradual erosion of Reddit’s utility for casual users if the app succeeds.
What Forum is
Forum pulls a user’s existing Facebook Groups into a focused feed, stripping away the algorithmic mix of friends, pages and ads that fills the main app. Discussions are organized by group, with posts, replies and the ability to pick up where a user left off. Meta says the feed surfaces “what real people are saying, not just what’s trending,” a direct swipe at the broadcast-style content that dominates other platforms.
The app comes with two AI features. An “Ask” tab lets users pose questions and receive answers compiled from discussions across groups, so someone researching a purchase or a health question gets a synthesis of what members have said. A second assistant helps group administrators moderate content and manage their communities. Both are built on Meta’s Llama models, according to the company.
Forum is U.S.-only for now, and it is not the company’s first attempt at the format. Meta, then known as Facebook, launched a standalone Groups app in 2014 and shut it down in 2017. The difference this time is the competitive context: Reddit has gone public, reached profitability and become the default destination for product research and niche advice, ground that Facebook Groups used to own.
Why Reddit, and why now
Reddit’s rise has been one of the quieter stories in social media. The company went public in 2024, posted its first quarterly profit in late 2025, and has built a business on search-driven traffic: millions of people append “reddit” to their Google queries and land on threads written by strangers. Meta wants that audience, and it wants it without building a new community from scratch.
The strategic bet is that Facebook Groups already contain the discussion Reddit hosts, just buried inside a platform built for broadcasting. Forum extracts those conversations into a focused app and gives them Reddit’s mechanics: organized topics, replies and the feel of a forum rather than a feed. Meta has done this before with Threads, which pulled Instagram’s social graph into a Twitter-style app and now claims a large share of the short-form text market.
The differences are structural. Reddit offers pseudonymity; Forum is tied to Facebook identities, though users can post under nicknames that administrators can unmask. Reddit’s value lies partly in its neutrality and its archive of accumulated answers; Forum’s lies in Meta’s scale, with billions of Group memberships already in place. Analysts see the trade-off as Forum’s core problem: it starts with community but lacks the anonymity that made Reddit the place people ask honest questions.
The market math
The competitive math is a study in asymmetry. Reddit is a public company whose revenue depends on keeping users and advertisers inside its own walled archive. Meta can lose money on Forum for years, as it did with Threads, and absorb the cost. Truist’s warning captures the realistic threat: not that Reddit users defect en masse, but that casual users, the ones who visit for a quick answer rather than community loyalty, start finding those answers on Meta’s properties.
Meta’s launch timing also connects to its broader restructuring. The same week, the company announced an AI-focused reorganization touching thousands of employees, and Forum is part of a strategy of spinning out smaller standalone apps after years of consolidating everything inside Facebook and Instagram. Threads, the Edits video editor and now Forum form a pattern: launch focused apps, let them compete, and grow whatever survives.
Bottom line
Meta’s Forum is a direct, if quiet, challenge to Reddit, and the market priced it in on day one. The app has real advantages, starting with the billions of Group memberships it can draw on, and real liabilities, starting with the identity question that made Reddit’s pseudonymous forums work. Forum does not need to beat Reddit to matter; it only needs to capture enough casual discussion to dent the economics that Reddit’s valuation rests on.
