In October, the Antisemitism Research Center (ARC) by CAM monitored 669 antisemitic incidents across the globe, an average of 21.6 incidents per day. Compared with October 2024, a 0.7% decrease in incidents (674 in October 2024 vs. 669 in October 2025) was recorded. From January 1 to October 31, 2025, a total of 5,785 incidents were tallied, 6.4% higher than the 5,439 incidents recorded from January 1 to October 31, 2024.
75.5% of the incidents the ARC recorded in October were linked to far-left ideology, followed by the Islamist (12%), unattributable (8.7%), and far-right (3.9%) categories. The data showed that the end of the war in Gaza following a U.S.-brokered ceasefire deal had no impact on levels of far-left antisemitism driven by hatred of the Jewish state.
266 antisemitic incidents were recorded in the United States in October, representing a 76.2% increase from the 151 incidents tracked in September. Compared with October 2024, the ARC monitored 12.2% fewer U.S. incidents (303 in October 2024 vs. 266 in October 2025).
143 antisemitic incidents were recorded in the United Kingdom in October, marking a 45.9% increase from the 98 incidents monitored in October 2024 and a 38.8% increase from the 103 incidents tracked in September 2025.
October saw significant action by governmental bodies worldwide to combat antisemitism. In the United States, federal officials opened a wide-ranging civil rights probe into antisemitism, while a bipartisan congressional resolution was introduced condemning Hamas’s violence against Palestinian civilians in Gaza. The U.S. Department of Education reached an agreement with the University of Virginia establishing new accountability measures and education initiatives to ensure a safer environment for Jewish students on campus. Following the deadly Yom Kippur terrorist attack at a Manchester synagogue, the British government advanced a new comprehensive plan to address rising antisemitism nationwide, and also announced targeted reforms within the National Health Service. In Germany, the government pledged a historic $1 billion for Holocaust survivor home care, strengthening long-term support for victims.
A series of new research studies published in October painted a stark picture of antisemitism’s global reach and evolving manifestations. A nearly one-year investigation found X had become “one of the most effective tools for spreading antisemitism in history,” while a separate report warned extremist groups were increasingly exploiting AI to amplify anti-Jewish propaganda. In the UK, official data confirmed Jews suffered the highest rate of religious hate crimes in England and Wales, and a new study documented a surge of antisemitic incitement on social media following the Manchester attack. In the U.S., a Washington Post poll revealed growing fears of antisemitism were prompting more Jews to hide their identity in public. Meanwhile, in Germany, researchers exposed neo-Nazi rappers using TikTok, Instagram, and Spotify to propagate hate speech and antisemitic narratives.
