MARA Holdings witnessed a dramatic after-hours stock surge on Thursday, with shares jumping nearly 17% after the digital currency mining firm announced a major collaboration with Starwood Capital Group to develop AI-focused data center facilities across its U.S. properties.
The stock touched $9.88 in extended trading sessions following the partnership announcement.
Marathon Digital Holdings, Inc., MARA
Under the agreement’s framework, MARA will contribute its existing data center real estate assets to the collaborative enterprise. Starwood Digital Ventures — the dedicated data center arm of Starwood, which manages over $125 billion in assets — will take the lead on design, construction, lease negotiations, and facility operations.
The two companies will jointly fund and manage these infrastructure projects.
The platform is expected to deliver more than 1 gigawatt of IT capacity in its initial phase. Future expansion plans call for capacity growth surpassing 2.5 gigawatts.
MARA retains the option to invest up to 50% in specific joint venture projects, allowing it to maintain ownership interest in revenue-producing operational infrastructure.
Strategic Pivot Toward AI Infrastructure
MARA’s existing facilities were originally constructed for Bitcoin mining purposes, but these sites now possess a critically scarce resource: direct access to large-scale power capacity.
As major technology companies aggressively pursue power resources for next-generation AI infrastructure, these mining facilities have gained unexpected strategic value.
CEO Fred Thiel described 2026 as marking “an inflection point,” referencing both the Starwood partnership and a separate agreement with Exaion to enhance enterprise AI capabilities.
This strategic repositioning aligns MARA with a wider industry trend of cryptocurrency miners repurposing their infrastructure for AI and high-performance computing uses. Bitfarms (BITF) recently rebranded to Keel Infrastructure as part of a similar shift from mining toward HPC and AI data center operations.
This industry-wide transformation accelerated after Bitcoin’s most recent halving event, which cut mining rewards in half. When combined with rising energy costs, weakening cryptocurrency prices, and heightened competition, mining sector profit margins have experienced significant pressure.
Cryptocurrency Operations Continue
Despite this infrastructure diversification, MARA continues its cryptocurrency mining business.
In his Q4 shareholder letter, Thiel made clear that “Bitcoin remains a core pillar of MARA’s strategy,” stressing the company’s continued belief in digital assets remains unwavering.
This strategic statement came alongside disappointing fourth quarter financial performance.
MARA posted Q4 GAAP EPS of negative $4.52, missing analyst expectations by $3.35. Revenue came in at $202.3 million, down 5.6% from the prior year and falling short of forecasts by $49 million.
The company recorded a net loss of $1.7 billion for the quarter, a stark reversal from net income of $528.3 million in Q4 2024. Roughly $1.5 billion of this loss resulted from fair value markdowns on digital assets held on the balance sheet.
Adjusted EBITDA came in at negative $1.5 billion, versus a positive $796 million in the same quarter last year.
MARA attributed the revenue miss to a 14% decline in the average price of bitcoin mined during the quarter.
The company is based in Hallandale Beach, Florida.
