ChatGPT just wiped Reddit off its sources. No announcement. 86% of its citations gone in a week. What happened: on August 8 OpenAI changed how ChatGPT searches. It stopped polling the open web for opinions and started firing targeted site searches. Those went from 0.4% to 17% of all queries in one day. Reddit's share fell from 3.8% to 0.5%. The stock is down almost 20% this past month. The takeaway for anyone building or marketing anything: AI might not need your SEO blog or a Reddit thread about your product anymore. Audit how you show up in AI search now. Data: Promptwatch, Aug 2026. #ai #chatgpt #seo #aisearch #reddit - @buildwithneej
