Three years after the 7 October 2023 terrorist attacks against Israeli civilians, our monitoring reveals that online antisemitism remains at significantly elevated levels. No platform monitored by OHPI has returned to pre-7 October levels. The initial attacks triggered an enormous surge in antisemitic content, which has continued until today. Antisemitism across the platforms we monitor has risen significantly since the initial post October 7 spike, with the most recent three-months having the highest levels observed in any period since OHPI began monitoring.

Alongside this sustained increase in antisemitism, there have been efforts both online and offline to erase the memory of October 7 and empathy for the victims. Pro-Palestine protests on October 7 2026 were advertised online with imagery glorifying the October 7 attacks and portrayed those responsible as martyrs or honourable fallen soldiers. 

Analysing the data we see that traditional antisemitism remains dominant across most platforms (and in total). This finding is significant in the context of recurring claims that seek to deny or minimise the problem of antisemitism. These claims often suggest the rise can be explained away as a result of anti-Zionist or pro-Palestinian content being “misclassified” as antisemitism. Our data does not support this. The nature of the antisemitism is largely of an older and more traditional kind, from claims of Jewish power to the accusation of deicide.

This is not to accept the argument of misclassification. Too many who argue “anti-Zionism isn’t antisemitism” are pushing for a free pass to engage in antisemitism, of whatever form, without consequences. Pro-Palestinian advocacy need not be antisemitic, yet too many seek to engage in antisemitism under the cover of calling it political advocacy, and too many stand by and allow it. Our data track antisemitism related to Israel, Israelis, Zionism and Zionists as a distinct form of antisemitism, what was once called “new antisemitism”. It is concerning that LinkedIn and Reddit together make up 15% of our data, yet account for 30% of this type of antisemitism. LinkedIn is the only platform where antisemitism related to Israel and Zionism is dominant and consistently accounts for more than 70% of the antisemitic material collected.

The nature and distribution of antisemitism also varies across platforms in other ways. Traditional antisemitism is most prevalent on almost all platforms monitored, but dominates particularly strongly on Gab and Telegram, platforms particularly popular with the far right. Surprisingly most Holocaust denial content is now on mainstream platforms. Rising levels of incitement to violence, particularly material promoting extremist ideologies such as Nazism, can be seen on YouTube and TikTok, usually in comments.

OHPI’s analysis demonstrates that since the spike in online antisemitism after October 7, 2023, there is a new normal where antisemitism is pervasive across social media. Its nature varies across platforms. Understanding the patterns is essential to identifying emerging threats, challenging antisemitic narratives, and informing effective responses. Continued monitoring is critical to ensure corrective measures, including regulation, have a meaningful impact.
