Snapchat Launches Topic Chats to Join Trending Conversations

Snapchat has rolled out Topic Chats, a new way for users to jump into public conversations about trending moments while keeping their personal profiles private. The feature appears across the app (chat shortcuts, search, Stories and Spotlight) and aims to blend the intimacy of private messaging with the reach of public discussion, while limiting direct contact from strangers.

Topic Chats let Snapchat users tap a yellow “Join the Chat” button and enter a public conversation focused on a trending subject — think sports highlights, viral memes or breakout TV moments. When you join, the chat looks and behaves like a normal Snapchat conversation: you can send messages, react, and view related Snaps. Topic Chats also surface Spotlight videos tied to the same topic, creating a loop between discovery and discussion.

Over the coming weeks the feature will roll out in the U.S., Canada and New Zealand. Snapchat will flag which of your friends are participating in a given Topic Chat, and any chat you join moves to the top of your Topic Chat page so you can return quickly.

Safety, privacy and moderation

Snapchat’s product design tries to keep the best of both worlds: public conversation without exposing your profile to everyone on the platform. Profiles remain private; users who aren’t your friends can’t add you or send direct messages. The company also says Topic Chats will be moderated, a critical control given the history of public chat threads attracting harassment, spam and misinformation.

That said, moderation at scale is difficult. Public, high-velocity conversations about breaking events can generate hostile or misleading content faster than moderators can act. Topic Chats’ success will depend on moderation techniques (automated filters, human review, and proactive detection) and the company’s ability to tune signals without over-censoring legitimate discussion.

For casual users, topic chats lower the friction to join cultural moments: instead of friending strangers or posting publicly from a personal account, you can participate in a focused conversation while your profile stays private. For creators and brands, Topic Chats create a new channel to surface Spotlight clips and amplify content tied to trending moments. For social researchers and platform designers, Topic Chats are an interesting experiment in combining ephemeral chat dynamics with public discovery.

Two practical scenarios illustrate the change:

• A viewer watching a reality TV episode can tap into a Topic Chat, share a reaction Snap, and see related Spotlight clips, all without exposing their friend list.

• During a major sports event, fans can aggregate play reactions, coordinate meet-ups or share clips, while still keeping direct messages and profile details locked down.

Potential Challenges and Considerations

1. Moderation scale: Topic Chats will need fast, effective moderation to prevent harassment and misinformation. Automated systems may help, but human oversight remains necessary for nuanced cases.

2. Echo chambers and toxicity: Public chats can amplify loud voices; product signals (who’s shown in a chat, ranking of messages) will shape whether discussions stay civil or become toxic.

3. Privacy expectations: Users must understand the exact privacy boundary — what remains private, what metadata is visible, and how participation affects discoverability.

4. Product complexity: Introducing public chat layers onto a private-messaging-first app can change social norms and long-standing user expectations about safety and intimacy.

Topic Chats reflects a broader trend: platforms built for private messaging are experimenting with controlled public surfaces to capture cultural moments and increase time-in-app. Snapchat’s approach attempts to minimise exposure risk by keeping account privacy intact and moderating content. If it works, Topic Chats could offer a replicable model for other messaging-first networks trying to enable public participation without sacrificing user trust.
