MARA has a major problem. A lawsuit filed on July 22 in the federal court of the Southern District of New York directly targets the mining giant, accused of hiding the true nature of its project in France during the acquisition of Exaion.
The acquisition, finalized on February 20, 2026, cost 148 million euros. The structure: 115 million euros in new shares, 33 million euros to buy existing shares. On paper, it looks like a typical industrial deal. But according to the lawsuit, the Bitcoin mining project at the heart of the operation was never mentioned in official communications. Not a word. And that’s where the issue lies.
François Garcin Demands 11.32 Million Euros
The man behind the lawsuit is François Garcin, founder of Argenthal. He and several affiliated companies — including Athanor, LLC and Argenthal Global Holdings Ltd — are demanding 11.32 million euros for unpaid fees. The mandate he signed in 2025 was clear: to develop MARA’s interests in France, creating data centers for Bitcoin mining. However, according to him, MARA never paid.
Garcin didn’t just send emails. He allegedly coordinated direct discussions with EDF, TotalEnergies, Engie, and other major French energy players. His mission, as he describes it: to convince the French government that the acquisition of Exaion represented a strategic advantage for the country. The discussions reportedly involved the offices of the Élysée and Matignon. Not insignificant interlocutors.
No public response from MARA so far.
Gérard Mestrallet, EDF, and Promised Billions
The court documents go further. Garcin is said to have drafted a strategic letter intended for EDF, a document establishing a direct link between electricity produced in France and future Bitcoin uses. The letter also addressed what the documents call “Token Economics” — essentially, an argument to convince EDF that French electricity and Bitcoin could be a good match.
And then there’s Gérard Mestrallet. The former CEO of Engie became a consultant for MARA in August 2025. According to the lawsuit, he discussed with a senior French official a potential investment program: 4 billion euros over three years, and up to 10 billion euros over a period of five to seven years. Figures that, if officially put on the table, would likely have changed the nature of discussions with Paris.
The lawsuit also mentions Fred Thiel — no title specified in the documents — who allegedly asked Garcin to reassure French authorities that MARA posed no strategic risk to the country. Thiel also wanted to prevent other companies from establishing similar partnerships with French players. Essentially: lock in the market before the competition arrives.
Implications for Foreign Investments in Crypto
The case raises a broader question. If the allegations are true, how did French authorities authorize the acquisition of Exaion without having the full picture? The lawsuit suggests that a communication strategy was specifically designed to influence the perception of French regulators — highlighting economic and energy benefits while downplaying aspects related to Bitcoin mining.
That might be the real issue. Not just the 11.32 million euros demanded by Garcin. But the question of whether the information provided to French authorities during the acquisition’s authorization was complete. That’s another story — and probably not the last.
French authorities have yet to comment publicly. No statement from the Élysée, Matignon, or EDF. Total silence from Paris.
The next steps are unfolding in New York. The judicial developments in the Southern District will likely dictate the pace. And if the documents produced in the proceedings surface, we will soon know if the communication strategy described in the lawsuit was as elaborate as Garcin claims. The 10 billion euros promised to France, for now, have no legal existence.
