How much does Reddit weigh in AI answers for B2B?

The deals behind the headlines

Reddit licenses its data to AI companies. That makes its content easy for those companies to use, not automatically dominant in every answer.

• Google, February 22, 2024: “Google now has access to Reddit’s Data API” ^[1]. Terms were not disclosed; the “$60 million a year” figure comes from press reports.
• OpenAI, May 16, 2024: OpenAI “will access Reddit’s Data API” and bring Reddit content into ChatGPT ^[2].
• Reddit’s IPO filing: data licensing arrangements signed in January 2024 with “an aggregate contract value of $203.0 million”, over two to three years ^[3].
• Litigation: in October 2025, Reddit sued Perplexity and other companies, alleging they scraped Reddit content from Google’s search results ^[4].

What studies measured

Reddit’s weight depends heavily on the engine, the topic and the month.

• Volatility. Semrush tracked 230,000 prompts over 13 weeks: ChatGPT cited Reddit in close to 60% of responses in early August 2025, then around 10% by mid-September ^[5].
• After the drop. Semrush’s Reddit study then ranked it No. 1 on Perplexity (4% share), No. 2 on ChatGPT search, which Semrush calls SearchGPT (13%) and No. 3 on Google AI Mode (9%) ^[6].
• AI Overviews. In Ahrefs’ June 2025 data, Reddit and Quora ranked high only in AI Overviews (7.4% and 3.6%), outside the top 10 for ChatGPT and Perplexity ^[7].
• B2B questions. Orbit Media tracks 72 B2B buyer questions weekly across four AI assistants (13,184 citations in total). In its latest weekly run, Reddit was “0% of Claude’s citations, 0% of ChatGPT’s, 3% of Perplexity’s, and 1% of Gemini’s”, although across the whole dataset Reddit was still Perplexity’s third most cited domain ^[8]. The author describes the results as directional.

One number to avoid: a chart circulated in 2025 presented Reddit as “40.1% of LLM citations”. The percentages in that chart add up to far more than 100%, so it cannot be a share of all citations.

What we measured in a B2B category

At the baseline of our published case study (a US B2B SaaS vendor in ITSM), we collected 12,985 citations across four AI assistants and Google AI Overviews. The two most cited domains were youtube.com (390) and reddit.com (373). For that category, Reddit threads were part of the answer. For another category, they may not be. See the case study.

What to do as a B2B brand

• Check before acting. Run your buying questions and list the cited URLs. If no Reddit thread appears, Reddit is not your priority.
• If threads appear, read them. Note which threads, which subreddits, and what is said about you and your competitors.
• Participate openly. Answer questions as a named employee or expert, disclose your affiliation, follow each subreddit’s rules. Undisclosed promotion is usually removed and damages trust.
• Fix the facts elsewhere too. Threads often repeat what is on review sites and comparison articles. Make sure those are accurate.
