MARA Holdings has finalized its acquisition of a 64% stake in French computing infrastructure operator Exaion, marking a significant shift towards artificial intelligence (AI) and cloud services. The deal, initially agreed upon in August 2025 with EDF Pulse Ventures, was completed after securing the necessary regulatory approvals, as announced by MARA on Friday.
The acquisition is part of a broader strategy by MARA to diversify its business beyond Bitcoin mining, a move that has become increasingly necessary as the mining industry faces growing economic pressures. French energy giant EDF will retain a minority stake and continue as a customer of Exaion, while NJJ Capital, the investment vehicle of telecom entrepreneur Xavier Niel, will acquire a 10% stake in MARA France.
A New Governance Structure
The new ownership structure will be reflected in Exaion’s board composition. The company’s board will now include three representatives from MARA, three from EDF Pulse Ventures, and one from NJJ Capital. Exaion’s CEO and co-founder will also hold a seat, alongside Xavier Niel and MARA CEO Fred Thiel.
Bitcoin Miners Embrace AI and Cloud Computing
The pivot to AI and cloud services is not unique to MARA. Several Bitcoin mining companies are exploring similar strategies to diversify their revenue streams. After the 2024 halving, which cut block rewards in half, and the subsequent rise in network difficulty, the economics of Bitcoin mining have become increasingly challenging. Companies like HIVE Digital Technologies and CoreWeave have already reported strong financial results from their AI operations, even during periods of weaker Bitcoin prices.
HIVE, for example, has leveraged its existing infrastructure to expand into AI and cloud computing, which has helped cushion the impact of volatile Bitcoin prices. CoreWeave, another prominent player, has transitioned from crypto mining to become a major provider of AI infrastructure, capitalizing on the declining demand for GPU mining.
Repurposing Mining Facilities
Other firms, including TeraWulf, Hut 8, IREN, and MARA, are repurposing their mining facilities and energy capacity to support AI data centers. This shift not only provides a steadier revenue stream but also aligns with the growing demand for high-performance computing (HPC) in the AI sector. In November 2022, CleanSpark announced plans to raise approximately $1.13 billion to fund the expansion of its Bitcoin mining and data center operations, signaling a trend towards integrated services in the tech and finance industries.
Bitcoin Mining Challenges Persist
Despite these strategic moves, Bitcoin mining remains a competitive and challenging field. The mining difficulty, a measure of how hard it is to mine new Bitcoin blocks, recently increased by 15% to 144.4 trillion. This uptick, which followed an 11% drop earlier in the month, underscores the ongoing pressure on miners to maintain profitability.
The higher difficulty level reinforces Bitcoin’s security but also increases the computational effort required to mine new blocks, further squeezing margins for operators already grappling with rising costs. The earlier drop in difficulty was attributed to severe winter storms in the United States, which disrupted power grids and forced many miners offline, leading to a temporary reduction in hash rate.
Looking Forward
MARA’s acquisition of Exaion and the broader industry trend of pivoting to AI and cloud services highlight the evolving landscape of the tech and finance sectors. As Bitcoin mining becomes more challenging, companies are seeking innovative ways to leverage their existing infrastructure and expertise. The success of firms like HIVE and CoreWeave suggests that the transition to AI and cloud computing can provide a viable and profitable alternative, ensuring long-term sustainability and growth in a rapidly changing market.
