Shares of Reddit slid about 6% on Friday after investors reacted to signs that Meta Platforms is once again attempting to challenge Reddit’s dominance in online discussion forums with a new experimental app called Forum.
The app, currently being tested on Apple’s iOS platform, is tied to Facebook Groups and is designed to facilitate topic-based online discussions and digital communities, according to analysts at Truist.
The move immediately revived longstanding fears among investors that Reddit’s core business model, organizing internet communities around shared interests and public conversations, could eventually face a serious threat from much larger technology rivals with deeper ecosystems, stronger advertising networks, and billions of existing users.

Truist analysts described Forum as “an attempt by the company to compete against Reddit as an online forum for public discourse” and warned that it “represents a new threat.”
The market reaction underscores how closely investors are watching competitive risks surrounding Reddit, whose valuation has increasingly depended on the durability of its highly engaged communities and its growing importance in the AI and digital advertising ecosystems.
Although Reddit shares remain under pressure, falling nearly 40% this year, the decline masks a business that has continued posting unusually strong growth. In April, the company reported its seventh consecutive quarter of revenue growth exceeding 60%, benefiting from improving advertising demand, AI licensing agreements, and stronger monetization of user engagement.
Meta, however, remains vastly larger and financially more powerful. The Facebook parent recently posted quarterly revenue growth of 33%, giving it enormous resources to experiment with new social products and aggressively compete in emerging online formats.
At the center of investor concern is whether Meta can siphon away Reddit’s more casual users — particularly people who visit discussion forums occasionally for advice, recommendations, or answers rather than participating deeply in long-standing communities.
“The risk from this move, if successful, is a gradual erosion of Reddit’s utility for casual users who have less community loyalty to Reddit and simply want answers,” Truist analysts wrote. “This would affect non-core Reddit users more than directly logged-in, habitual users.”
That distinction matters because Reddit’s strongest competitive advantage has historically been the depth and stickiness of its communities. Many of its users are intensely loyal to niche forums focused on topics ranging from finance and gaming to health, sports, and technology. Those communities often develop unique cultures, moderation systems, and user identities that are difficult to replicate elsewhere.
But the broader internet industry is shifting rapidly.
Online discussion itself has become increasingly valuable in the age of artificial intelligence because platforms such as Reddit contain vast archives of human-generated conversations, recommendations, and problem-solving exchanges. AI companies, including OpenAI and Alphabet, have struck licensing deals with Reddit to access that data for training AI models.
That has elevated Reddit from a niche social platform into a strategically important repository of human interaction data.
Meta’s renewed push into forums may therefore be about more than social networking. The company is aggressively integrating AI tools across its products and may view discussion-based communities as both a source of engagement and a future data advantage in the AI race.
The launch of Forum also reflects Meta’s broader strategy of cloning or adapting successful digital formats developed by rivals. Over the years, Meta has borrowed heavily from competitors, including Stories from Snapchat, short-form video from TikTok, and marketplace features from e-commerce platforms. The company also launched Threads in a copy of X’s microblogging format.
This is not Meta’s first attempt at building a standalone community-discussion product. More than a decade ago, the company launched a separate Facebook Groups app before shutting it down in 2017. However, Facebook Groups itself never disappeared and still hosts millions of communities globally.
The difference now is that public online discourse has become more commercially valuable and strategically important than when Meta first experimented with standalone groups.
Reddit, meanwhile, faces growing pressure to prove it can evolve from a culturally influential platform into a durable, large-scale advertising and AI-era business. While user engagement remains strong, investors remain cautious about the company’s ability to fend off competition from much larger technology firms.
The company’s stock decline this year also underpins broader market skepticism toward consumer internet companies outside the dominant mega-cap AI trade. Even firms posting strong revenue growth have struggled to maintain momentum as investors concentrate capital into semiconductor, infrastructure, and frontier AI names.
Still, many analysts believe Reddit retains a structural advantage because authentic online communities are difficult to manufacture artificially. The platform’s culture, moderation dynamics, and years of accumulated user-generated discussions create network effects that competitors may struggle to reproduce.
