Why is Reddit the citation cartel?

Reddit commands 40.1% of AI citation share — more than any other single domain. The 2024 licensing deals with Google ($60M) and OpenAI confirmed that Reddit threads are a primary training and retrieval source for every major AI engine.

How do AI engines use Reddit?

ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews retrieve Reddit threads for product comparisons, brand sentiment, how-to queries, and category recommendations. The upvote-downvote system functions as a quality signal AI models rely on.

Should brands have a Reddit PR strategy?

Yes, but the strategy must be native. Reddit communities reject overt marketing. Effective brand presence on Reddit requires genuine participation, transparent disclosure, and subreddit-specific tone calibration.

What happened with the Reddit IPO?

Reddit went public in March 2024, validating the commercial value of its user-generated corpus — the same corpus that makes it the most-cited domain across AI engines.
