How much of HN is AI?

As of June 2026, approximately 50% of Hacker News' daily top stories are about AI or AI-generated, representing a significant shift in the platform's content dominated by AI-related announcements, opinion pieces, and AI-written articles. The author conducted systematic surveys in February and June 2026, using AI detection tools to identify both AI-related topics and AI-generated content, finding that AI stories consistently occupy multiple top positions nearly every day. This trend is notably more pronounced than previous tech fads like cryptocurrency and NFTs that appeared on the platform around 2018.
