Adweek, citing fresh data drawn from four separate sources, reports that YouTube has eclipsed Reddit Inc (NYSE:RDDT) as the leading social platform cited by large language models. The development marks a clear change in which social channels supply the human-generated material that AI systems reference when constructing responses.
Reddit had long held a dominant role because of its text-forward, forum-style format. The new report, however, finds that YouTube now appears more frequently in LLM outputs. According to metrics highlighted by Bluefish, YouTube was referenced as a source in 16% of LLM answers over the past six months, compared with 10% for Reddit over the same period.
Adweek’s coverage points to advances in how machines process video content as a key factor. Where LLMs once struggled to incorporate information from visual media, the availability of video transcripts, explainer segments, and other text-based material tied to YouTube videos has made the platform more readily readable by language models. These ancillary text artifacts have allowed video to serve as an effective channel for conveying searchable, machine-consumable knowledge.
The shift has strategic ramifications for organizations that have prioritized forum-driven search engine optimization. Brands and marketing teams that historically focused on text forums may need to reassess their content pipelines to ensure expertise is captured within the searchable and transcript-rich environment of the world’s largest video site. The data reported by Adweek suggests content strategy - particularly for firms seeking visibility in AI-generated responses - may increasingly favor video-derived assets.
Market movement tied to the report was modest: Reddit stock was described as steady and was up 0.4% in afternoon trading on Monday.
The report also includes promotional performance claims for an investment product, noting that, year to date, two out of three global portfolios are outperforming their benchmark indexes with 88% of holdings in the green. It additionally states that a flagship strategy doubled the S&P 500 within 18 months and lists past winners such as Super Micro Computer (+185%) and AppLovin (+157%).
As video-derived text becomes more accessible to LLMs, the channels that feed AI reference frameworks appear to be evolving. The reported data indicate a measurable reordering of social-platform influence in AI citations, with potential implications for content production and digital marketing priorities.
