Tether-affiliated companies sold Northern Data's mining business, and Rumble subsequently announced its acquisition of Northern Data.

PANews reported on December 19th that, according to the Financial Times, Tether's AI data center company, Northern Data, sold its Bitcoin mining business, Peak Mining, for up to $200 million to companies controlled by Tether founder Giancarlo Devasini and CEO Paolo Ardoino (including Highland Group Mining and Alberta ULC, 2750418). Days after the deal was announced, Rumble, a conservative social media platform in which Tether holds a nearly 50% stake, agreed to acquire Northern Data for approximately $767 million. Northern Data was previously under investigation by the European Union for alleged large-scale tax fraud, which the company denied, stating it was cooperating with the investigation.
