arXiv Caps Submissions at Two Papers per Author per Month

arXiv is a free preprint server where much of the newest AI research appears first. According to an article on DEV Community published on 10 November 2026, arXiv received 40,363 submissions in September 2026, compared with 20,569 two years earlier, roughly double the volume. The article argues that a flood of AI-generated research papers has been a major driver of the surge. In response, starting on 1 October 2026, arXiv limited each submitter to two new papers per calendar month, while keeping the number of active submissions per submitter capped at three. The article notes that the change matters beyond academia: journalists, investors and product teams often treat phrases like "a new paper on arXiv shows" as evidence, so if more papers carry fake references or unchecked results, downstream readers inherit those problems. The publicly reported measure therefore extends well past the university setting. For now, the information available is limited to this single article, and the summary is based solely on what it states rather than on an official arXiv announcement that could be independently verified.
