The 130 Yemen-based X accounts and 67 WhatsApp business accounts identified by TTP offered high-powered rifles, grenade launchers and other military equipment for sale. Many of the arms dealers were subscribers to X Premium and users of WhatsApp Business – services that are supposed to be moderated. A few of the Houthi-linked arms dealers interacted with Musk himself on X. When Musk posted a video of himself firing a Barret .50-caliber sniper rifle in September 2023, three arms dealers replied to him advertising their own guns, which included two AR-15s. TTP found that the vast majority of the Houthi-affiliated arms dealers’ accounts on X and WhatsApp were created after the layoffs at both companies.
