New research from CASM Technology and ISD has found a major and sustained spike in antisemitic posts on Twitter since the company’s takeover by Elon Musk on October 27, 2022.

Powered by the award-winning digital analysis technology Beam – and based on a powerful hate speech detection methodology combining over twenty leading machine-learning models – researchers found that the volume of English-language antisemitic Tweets more than doubled in the period following Musk’s takeover.

In total, analysts detected 325,739 English-language antisemitic Tweets in the 9 months from June 2022 to February 2023, with the weekly average number of antisemitic Tweets increasing by 106% (from 6,204 to 12,762), when comparing the period before and after Musk’s acquisition.
