MARA reported a $1.71 billion quarterly loss as Bitcoin fair‑value markdowns hit earnings and the company laid out a major push into AI and high‑performance compute. MARA Holdings (MARA) reported a fourth quarter 2025 net loss of $1.71 billion, or $4.52 per diluted share, compared with net income of $528.3 million, or $1.24 per diluted share, in the same period a year earlier.
