A law enforcement raid targeting Northern Data AG, a Frankfurt-listed technology firm backed by Tether Holdings SA, occurred in late September 2025. The operation was led by German prosecutors and involved multiple European agencies, with a focus on Northern Data’s offices and related facilities. Here is our report.
Purpose and Context
Prosecutors are investigating whether Northern Data misrepresented the use of roughly €500 million (about $586 million) worth of NVIDIA AI chips. The alleged issue centers on whether the chips, which the company claimed would be used for artificial intelligence and cloud computing (eligible for tax breaks), were actually employed for cryptocurrency mining at their Swedish site. This type of misrepresentation could constitute tax fraud, since Sweden ended tax incentives for crypto mining but maintained them for data center AI operations starting in 2023.
Tether’s Role
Tether Holdings SA, issuer of the USDT stablecoin, is the majority shareholder in Northern Data. Although named in reports due to its investment, Tether stated it is not involved in Northern Data’s day-to-day management and was unaware of the investigation prior to the raid. Tether clarified that Northern Data represents only a small part of its diverse investment portfolio, with no direct operational overlap.
Historical and Industry Implications
Northern Data previously focused on cryptocurrency mining but began shifting toward AI and cloud computing in response to changing energy costs and regulatory pressures. The raid is part of a broader crackdown following accusations about past governance, including fraud and tax evasion allegations from former directors, which were previously withdrawn. The scrutiny reflects heightened regulatory risks at the intersection of digital asset infrastructure and emerging AI tech, especially for companies with crypto origins now seeking to rebrand as AI service providers.
