Bitkern Group Pivots from Bitcoin Mining to AI Data Centers
Bitkern Group, an Austrian company founded by Stefan Kern, has shifted its focus from Bitcoin mining to AI-ready data centers. The company reports around 50 million euros in revenue, having operated mining infrastructure at over 20 sites since 2017. Through its new venture, Castellan Intelligence, Bitkern builds data centers for hyperscalers and neoclouds. The transition is driven by the stability of long-term contracts (15-20 years) compared to volatile mining earnings. Listed miners like Core Scientific or Iren have seen significant valuation increases. The article discusses the growing demand for AI infrastructure, the energy challenges (with gas power plants being built behind the meter in the US), the high capital costs (up to 26 million euros per AI data center with GPUs), US export restrictions on chips, and the trend towards sovereign AI with open-source models. The company faces criticism from residents and climate activists regarding energy consumption.
The article highlights the strategic shift of a crypto mining company into AI data center infrastructure, reflecting a broader industry trend. It provides insights into the growing demand for AI compute capacity, the economics of data centers, and the challenges related to energy and capital. This is highly relevant to AdTech/MarTech as AI infrastructure underpins the future of digital advertising and personalized experiences.

Crypto Miner Iren Shifts to AI Infrastructure
CNBC Pro contributor Todd Gordon reports that Iren is transitioning from bitcoin mining to AI infrastructure, with AI cloud services revenue nearly doubling to $33.64 million in fiscal Q3. The company announced a five‑year agreement with NVIDIA to deploy Blackwell GPUs across 60 megawatts in Texas and granted NVIDIA a 5‑year right to buy up to 30 million shares at $70 (up to $2.1 billion). Microsoft reportedly signed a $9.7 billion deal to access Iren’s Nvidia GB300 chips, and Iren agreed to purchase $1.8 billion of equipment from Dell. Revenue forecasts project rapid growth through fiscal 2029, though Gordon notes the company’s financials remain messy. The piece mixes fundamental disclosure with technical chart analysis and personal trading disclosures from Gordon, founder of Inside Edge Capital, LLC.
Tour of AI Data Center Highlights Infrastructure Supply Chain
CNBC toured CoreSite’s NY3 AI-optimized data center in Secaucus, New Jersey, and reported how hyperscaler demand is driving a surge in AI-focused data center infrastructure. CoreSite (owned by American Tower) and facility designers like Prime Data Centers described power sourcing, cooling, fiber connectivity, chips, and networking as the five critical buckets for modern AI centers. The story cites major vendors and customers — Amazon, Alphabet, Meta Platforms, Microsoft, OpenAI, Anthropic — and supplier companies benefiting from the buildout including Nvidia, Broadcom, Corning, GE Vernova, Eaton, Schneider and Dover. The article includes recent vendor financials and strategic deals (Corning fiber supply deals, Broadcom–Meta partnership, GE Vernova orders), and emphasizes solutions such as liquid cooling and fuel cell power as responses to rising energy and thermal demands.
AI Data Center Boom 'Stress‑Tests' Insurers and Lenders
Rapid private-capital financing and large-scale deals for AI data centers are creating capacity and risk strains for insurers and lenders. McKinsey estimates global data-center spending could reach $7 trillion by 2030, and Preqin data show private infrastructure data-center deals were consistently above $10 billion last year, including a $40 billion consortium purchase of Aligned Data Centers involving Nvidia, Microsoft, BlackRock and xAI. Insurers say concentrating tens of billions in single campuses has created capacity and underwriting challenges, while new financing structures—such as GPU-backed loans—raise lifecycle and opacity risks. CoreWeave announced an $8.5 billion investment-grade GPU-backed deal. Industry participants (insurers, brokers, law firms, and senators) have raised concerns about off‑balance-sheet financing, concentration risk, and potential second‑order litigation for downstream investors.
