Reddit shares slide 6% after Meta drops similar app called Forum

Reddit Inc. (RDDT) faced its first major competitive trial since going public, watching its stock tumble nearly 6% on Friday, May 22, 2026. The sudden sell-off was triggered by news that Meta Platforms has quietly rolled out a standalone iOS app called Forum, a direct, "Reddit-coded" attack on the open online discussion market.

The unexpected launch introduces a new rival right where Reddit is traditionally strongest, shaking investor confidence in the long-term exclusivity of Reddit’s community data and user engagement model.

What is Meta Forum?

Spotted without a formal announcement on the Apple App Store by social media consultant Matt Navarra, Forum is essentially a specialized spinout of Facebook’s massive Groups feature.

Rather than forcing users to navigate the cluttered, algorithm-heavy feeds of the main Facebook or Instagram apps, Forum isolates community-driven, topic-based discussions into a clean, dedicated space.

In a direct nod to Reddit's core appeal, Forum allows users to interact using anonymous handles or nicknames. However, group administrators retain the ability to see the real Facebook identities behind the accounts to curb toxicity.

Bi-directional syncing

The app doesn't split the user base. Any post or comment made inside Forum seamlessly mirrors back to the parent Facebook Group ecosystem and vice versa.

The interface filters out family updates and traditional public social feeds, focusing exclusively on niche Q&A, recommendations, and deep-dive community threads.

The AI advantage: "Ask" and admin assistants

Forum arrives out of the gate with two highly functional artificial intelligence systems built natively into the platform.

The first is Ask, an AI search tab that saves users from having to manually scroll through years of unstructured archives. A user can type a question, and the tool instantly aggregates and synthesizes "real answers from real people" across all the various groups they have joined.

The second tool is an AI-powered co-pilot designed to handle content moderation and community management workflows for group administrators.

According to internal leaks, the app is part of a broader corporate push championed by CEO Mark Zuckerberg to use AI efficiencies to rapidly build and test up to 50 specialized experimental apps to diversify Meta's long-term revenue streams.

Wall Street reacts

While investment banks like Truist noted that Forum is an undeniable gray-zone threat to Reddit, institutional analysts are closely watching the long-term impact on user retention and data monopolies.

Reddit’s premium valuation is heavily propped up by its status as an un-replicable goldmine of authentic, human-generated conversational data. By carving out a separate, clean space for its own billions of Group users, Meta is attempting to prove that Reddit's community model isn't as insulated from direct competition as previously assumed.

Reddit (NYSE:RDDT) shares, which had already faced recent pressure from insider selling cycles, closed the trading session down 5.8%, settling near $543.
