Even before major brands like Apple, Disney, and IBM paused their ad spending on X in the wake of Elon Musk’s endorsement of an antisemitic post, the company formerly known as Twitter had seen its revenues severely impacted by brand safety concerns. According to an October forecast from Insider Intelligence, X ad’s business was on track for a 54.4% year-over-year decline in worldwide ad spending, from 2022 to 2023. With the additional advertiser pull-outs, that decline may be even more significant, analysts now believe.

X is facing a potential loss of sizable ad spend, as a number of advertisers have paused or stopped their ad campaigns on X after owner Elon Musk amplified antisemitic conspiracy theories on the platform. Among the brands who have since stopped advertising on X are Apple, Comcast/NBCU, Disney, Warner Bros., IBM, Paramount, Lionsgate, and the European Commission.
