41% of LinkedIn long-form posts are AI-written — and it’s an undercount
a pangram study of 1m posts found linkedin leads with 41% ai-generated long-form content, far outpacing x/twitter and substack. the real rate is likely higher, signaling a systemic pollution of professional feeds.
a study of 1m posts from april to june 2026 revealed that 41% of long-form posts on linkedin are ai-generated, compared to 10% on substack. linkedin produced the majority of detected ai content despite making up only a third of the total dataset analyzed. the detection model, pangram 3, boasts a 0.01% false positive rate but is likely more accurate at identifying human text than ai text, suggesting the true saturation is higher. this inundation of 'slop' threatens the utility of professional networks and forces platforms to implement automated moderation against generated content.
