   Mathematician Alex Gerko's AI-driven XTX lifts him to No. 8 on UK rich list

   Alex Gerko, a 46-year-old mathematician, ranks eighth on the Sunday Times 2026 UK rich list with £16.006bn (about RMB 141.7bn), up £7.261bn from 2025, according to reports citing the list. He owns roughly 75% of XTX Markets, the quantitative market maker he founded in 2015, which uses machine learning to forecast prices and quote liquidity directly to clients; XTX's site says its research cluster has more than 25,000 GPUs, covers over 53,000 instruments across 35 countries, and handles about $250bn in daily trading volume. Its three main UK entities reported combined after-tax profit of about £1.71bn in 2025, but public materials do not break out AI's separate profit contribution, and Gerko's gains largely reflect equity valuation.

   arXiv caps submissions at two per month as AI paper flood strains moderators

   arXiv began enforcing a submission rate limit on October 1, 2026, allowing each submitter at most two papers per calendar month while keeping the existing cap of three active submissions at any time; the rule covers all categories, counts only the person submitting, and rejected papers still consume a slot unless deleted before publication. arXiv calls it a temporary measure: September 2026 brought 40,363 submissions, up from 20,569 two years earlier and 9,869 in September 2016, with cs.AI submissions growing more than sixfold in two years and generating nearly 9,000 support tickets. Editorial Advisory Council chair Thomas G. Dietterich said a small share of authors submit many low-quality, thin or AI-written papers, consuming a disproportionate share of volunteer moderators' time and delaying others by days or weeks; arXiv left Cornell University on July 1, 2026 to become an independent nonprofit and received $17.2 million in pledges in late September, partly to handle AI-generated content.
