Recently, I paid attention to a quite interesting move in the mining industry - MARA Holdings has just completed acquiring a 64% stake in Exaion, a data infrastructure provider from France. This transaction was initially agreed upon in August 2025 and has just been fully approved.

What’s notable here is the rather complex ownership structure. EDF Pulse Ventures still holds the role of minority shareholder and customer. But the interesting part is NJJ Capital - the investment firm of telecommunications billionaire Xavier Niel - will hold a 10% stake in MARA France. This is a well-structured three-way alliance, with Fred Thiel (CEO of MARA) and Xavier Niel himself expected to sit on the board along with other representatives.

Why is this important? Because it’s a different step compared to pure mining. Miners are now seeking to diversify revenue streams - they can no longer rely solely on block rewards. Bitcoin mining difficulty has just increased by about 15% to 144.4 quintillion, putting pressure on profit margins as energy costs continue to rise.

MARA’s approach is very clear: leveraging existing infrastructure and energy to build data centers aimed at AI. Instead of just mining Bitcoin, they can provide GPU computing capacity for enterprises that need large-scale data processing and AI. This creates a more stable revenue stream, less dependent on crypto price volatility.

This trend has become quite evident. Other mining companies are doing the same - HIVE Digital reports strong growth driven by AI initiatives, CoreWeave has fully shifted from mining to providing AI infrastructure. Even companies like TeraWulf, Hut 8 are restructuring their assets along these lines.

The governance structure in the MARA-Exaion deal is also cleverly designed. MARA, EDF Pulse Ventures, and NJJ Capital will each have a seat on the board, along with Exaion’s leadership. This arrangement ensures that different stakeholder interests are represented, while maintaining operational continuity.

Looking more broadly, what’s happening here is a fundamental shift. The cryptocurrency mining industry is evolving from a one-dimensional model (just mining) to an integrated model (mining + computing infrastructure). The MARA-Exaion alliance, with NJJ Capital’s participation, is a clear example of this trend.

For investors, this provides a clearer vision: instead of relying solely on Bitcoin price cycles, mining companies can build diverse revenue streams from high-value computing services. That’s why this transaction is important - it shows how crypto businesses can survive and grow more sustainably in a volatile market.
