MARA Holdings, Inc.

MARA Holdings, Inc., formerly Marathon Digital Holdings, is a publicly traded company that operates at the intersection of energy, compute, and digital capital. Founded on February 23, 2010, as Marathon Patent Group, a patent holding firm, the company pivoted in the late 2010s toward blockchain infrastructure and digital assets. Today it is one of the world's largest publicly traded miners of both bitcoin and kaspa, and as of August 2025, it holds the position of second-largest corporate holder of bitcoin globally.

The company's operations span North America, the Middle East, Europe, and Latin America, with a focus on converting excess or stranded energy into digital capital. A notable project is a joint venture that taps 37 megawatts from the Hardin Generating Station, a coal plant in Montana, to power an adjacent Marathon-built bitcoin data center. This move has drawn criticism from environmental advocates concerned about the carbon footprint of bitcoin mining.

MARA's strategy includes aggressive purchases of bitcoin and mining equipment, and the company has expanded into AI compute to monetize its energy assets further. Its headquarters are in Hallandale Beach, Florida. The company trades on NASDAQ under the ticker MARA. [edit]
