Marathon Digital's $730M Trading Volume Surge Propels Stock to 158th Rank Amid Strategic Exaion Acquisition for AI Expansion

Marathon Digital Holdings (MARA) closed 0.89% higher on August 13, 2025, with a trading volume of $730 million, representing a 72.94% surge from the previous day’s activity. The stock ranked 158th in trading volume across the market. The move followed the announcement of a strategic investment in energy firm EDF’s data center and cloud subsidiary, Exaion.

MARA secured a 64% controlling stake in Exaion through an upfront cash investment of approximately $168 million, with an option to acquire an additional 11% by 2027 for $127 million. The partnership aims to leverage Exaion’s infrastructure to expand MARA’s capabilities in AI/high-performance computing (HPC) and cloud solutions. EDF will retain a minority stake and continue as a client, while the transaction is slated to close in Q4 2025. Legal and financial advisors from Darrois Villey Maillot Brochier, Stifel Financial Corp., and Coblence avocats are supporting the deal.

Exaion, established in 2020, operates four data centers and 1,250 GPUs, offering Web3-based services and private cloud environments. Its Sherbrooke, Canada, facility houses a quantum computer from Quandela. The company’s alignment with renewable energy and modular infrastructure aligns with MARA’s focus on stranded energy assets, such as its Texas and North Dakota cryptomine powered by flared natural gas. The acquisition is expected to accelerate international deployment of Exaion’s commercial services.
