Because Peak Mining was the dedicated Bitcoin mining arm of Northern Data AG, its corporate history is completely entangled with the parents and partners.
While Peak Mining hasn't been hit with standalone regulatory fines, its operations have sat directly at the center of the "questionable activity" and restructuring maneuvers involving Northern Data and Tether.
The direct links to verifiable documentation and reporting on the primary allegations and legal matters involving Peak Mining are outlined below:
Peak Mining Controversy
The Ultimate Insider Shell Game
2025
-
Once the 2024 whistleblower lawsuit was dropped, Northern Data and Tether executed the sale of Peak Mining anyway—but used a regulatory loophole to shield it from public view. source
-
The Questionable Activity: In late 2025, Northern Data officially sold Peak Mining for $200 million. When they announced the sale to the public, they entirely omitted who the buyers were. source
-
The Discovery: An investigative exposure by the Financial Times revealed the buyers were three separate shell companies (Highland Group Mining, Appalachian Energy, and an unnamed Alberta firm). Corporate filings showed that the directors of these buying entities were none other than Giancarlo Devasini (Tether co-founder) and Paolo Ardoino (Tether CEO).
-
The Corporate Loophole: Because Northern Data operated on m:access (an unregulated, secondary segment of the Munich Stock Exchange), they were not legally required by German watchdogs to report "related-party transactions". Tether executives essentially bought Peak Mining from a company they heavily controlled, setting prices and terms completely behind closed doors.
The Failed "Elektron Energy" Deal
2024
-
Before Peak Mining was successfully sold, Northern Data attempted to quietly offload the business in a way that raised immediate internal flags. source
-
The Transaction: In August 2024, Northern Data announced it was selling Peak Mining to a firm called Elektron Energy for $235 million.
-
The Fallout: The deal abruptly collapsed. Corporate whistleblowers and market researchers pointed out that Elektron Energy was actually an undisclosed shell company linked back to Tether’s own leadership. Facing intense legal scrutiny from the ongoing California whistleblower lawsuit (which was active until October 2024), Northern Data was forced to let the transaction fall through.
The H100 GPU "Bait-and-Switch" Tax Probe
-
Peak Mining and Northern Data's Swedish units became the target of a major European Public Prosecutor's Office (EPPO) criminal fraud investigation. source
-
The Questionable Activity: In 2023, Northern Data bought 10,000 top-tier Nvidia H100 processors for €400 million. Because Sweden aggressively subsidized and provided massive tax breaks for companies building out Artificial Intelligence (AI) infrastructure, Northern Data avoided roughly €100 million in Value-Added Tax (VAT).
-
The Allegation: EU prosecutors suspect that instead of using these mega-chips for AI workloads, the company diverted the data center capacity to crypto mining operations under Peak Mining.
-
Why it's questionable: In 2023, Sweden strictly revoked tax benefits for cryptocurrency mining. Prosecutors allege Peak Mining deliberately masked their power use and crypto activities as "AI compute" to illegally hang onto massive tax breaks, sparking the major September 2025 office raids and multiple arrests for tax evasion and money laundering.
September 2025
Corpus Christi, Texas
2023 - Present
-
The Asset: A massive 75-acre data center complex with a massive 600-megawatt (MW) grid connection directly into the Texas ERCOT power market.
-
Current Status: It is currently drawing 100 MW of power specifically for active Bitcoin mining, operating as the physical crown jewel of the North American infrastructure.
-
The Resource Controversy: The site utilizes heavy liquid-immersion cooling setups. Public records requests revealed the facility consumed over 11 million gallons of fresh water in a single year (averaging ~127,500 gallons per day), sparking severe local backlash during a regional water crisis.
-
The Tax Loopholes: Under a renegotiated Industrial District Agreement (IDA), the facility completely escaped personal property taxes on its tens of thousands of high-value mining rigs. City ledgers show it paid a meager $2,639 in lieu of taxes over a two-year span.
-
The Ownership Shuffle: To clean up its balance sheet for the 2026 Rumble merger, Northern Data officially offloaded this physical asset into the $200 million Peak Mining sale to Tether-controlled shell companies. However, Northern Data kept a 5-year earn-out option guaranteeing them up to $150 million of the mining profits.
