One in four math preprints now acknowledge AI use, up from 4% just five months ago

In March, fewer than 5% of math papers posted to arXiv disclosed any use of artificial intelligence. By August 20, that number had crossed 24%. That’s not a gentle upward trend. That’s a vertical line on a chart that would make a growth-stage startup jealous. The data comes from a preprint titled “The Gold Rush in AI4Math: Where Are We Now?” authored by Jiashun Jin, Zheng Tracy Ke, and Bingcheng Sui, which analyzed 32,944 mathematics submissions to arXiv between March 1 and August 20, 2026. The findings paint a picture of a discipline in the middle of a rapid, and largely voluntary, transformation. The numbers behind the shift The headline stat, 24.14% of math preprints acknowledging AI by August, is striking on its own. But the more telling metric is what the researchers call “substantive AI contributions,” meaning cases where AI didn’t just proofread or format but actually contributed to the mathematical work itself. That figure jumped from 1.39% in March to 14.09% by August 20. In other words, roughly one in seven math papers now features AI doing real intellectual heavy lifting. Out of the 32,944 submissions analyzed, 3,575 confirmed some form of AI usage. Of those, 1,712 invol...
