ArXiv caps submissions at two per month as AI paper flood overwhelms the preprint server
arXiv limits each author to two monthly submissions after AI-fueled volume reached 40,363 papers in September 2026.
Starting October 1, 2026, arXiv will limit each submitting author to two papers per calendar month across all categories, while keeping the existing cap of three active submissions. Monthly volume reached 40,363 in September 2026, up from 20,569 in September 2024 and 9,869 in September 2016, with cs.AI growing more than sixfold in two years and generating nearly 9,000 support tickets. Moderators report thin salami papers and AI-written text; rejected submissions still count, and authors can face a one-year ban for unverified LLM outputs. arXiv is becoming an independent nonprofit after leaving Cornell, backed by $17.2 million from the Simons Foundation International, XTX Markets, and the Siegel Family Endowment.
- From October 1, 2026, arXiv allows two submissions per author each month.
- September 2026 logged 40,363 submissions, up from 20,569 in 2024.
- cs.AI submissions grew more than sixfold in two years, straining moderators.
- Simons Foundation, XTX Markets, and Siegel Family Endowment pledged $17.2 million.
- Authors can already face a one-year ban for unverified LLM outputs.
