French deal expands MARA’s AI and cloud ambitions
MARA Holdings has finalized its acquisition of a controlling stake in French computing infrastructure provider Exaion, marking a significant step in the Bitcoin miner’s pivot toward artificial intelligence and cloud services.
The transaction, first announced in August 2025, gives MARA France a 64% stake in Exaion following regulatory clearance. EDF Pulse Ventures, the venture arm of French energy giant EDF, will retain a minority position and remain a commercial partner.

The agreement also introduces new strategic ties. NJJ Capital, the investment vehicle of telecom entrepreneur Xavier Niel, will acquire a 10% stake in MARA France as part of a broader partnership. Exaion’s board will now reflect the updated ownership structure, with representation from MARA, EDF Pulse Ventures and NJJ, alongside company leadership.
The move positions MARA more firmly in Europe’s regulated data infrastructure landscape, where demand for AI workloads and sovereign cloud capacity continues to rise.
Miners diversify as economics tighten
The acquisition underscores a broader trend among publicly listed Bitcoin miners seeking to reduce reliance on block rewards.
Since the 2024 halving cut mining subsidies in half, operators have faced shrinking margins amid higher network difficulty and energy costs. As a result, several companies have begun repositioning their energy infrastructure and data centers to support AI cloud and high-performance computing services.
HIVE Digital Technologies has reported that expanding its AI operations helped cushion volatility in Bitcoin markets. CoreWeave, once tied to GPU crypto mining, has transformed into a major AI infrastructure provider. Other firms, including Hut 8, TeraWulf and IREN, have similarly repurposed mining capacity for AI-driven workloads.
For MARA, Exaion provides immediate exposure to established computing infrastructure and enterprise customers, rather than building capacity from scratch.
Rising mining difficulty adds pressure
The timing is notable. Bitcoin mining difficulty recently climbed roughly 15% to 144.4 trillion, rebounding from an earlier drop tied to winter storms in the United States that temporarily reduced hash rate. Higher difficulty
strengthens network security but also increases the computational effort required to mine new blocks.
For miners, that translates into thinner margins, especially when combined with post-halving reward reductions and fluctuating Bitcoin prices.
The shift toward AI and data center services offers a potential hedge. Unlike mining revenues, which depend heavily on Bitcoin’s price and network conditions, AI contracts can provide more predictable cash flow.
