They Say Gartner is Dead. Clearly, They Haven’t Checked Their LLM Sources.

An investigation into what sources LLMs like ChatGPT and Claude actually use when answering cybersecurity market research questions. After testing 15+ cybersecurity categories, the author found that LLM recommendations closely mirror Gartner and Forrester Magic Quadrant leaders, with over 50% of cited sources being vendor-authored content. For emerging categories like AI SOC, 100% of sources were vendor-written. The research also reveals a strong US-centric geographical bias, even in European LLMs like Mistral Le Chat. The conclusion: LLMs don't provide independent market analysis — they repackage analyst reports and vendor SEO content, creating a self-fulfilling prophecy that favors large, well-optimized brands over smaller or non-US vendors.
