MARA Holdings experienced a significant 17% increase in after-hours trading Thursday following the bitcoin mining company’s announcement of a substantial agreement with Starwood Capital Group to create AI data centers throughout its United States locations.
Shares reached $9.88 during post-market activity after the partnership was revealed.
Marathon Digital Holdings, Inc., MARA
The arrangement calls for MARA to provide its current data center locations to the partnership. Starwood Digital Ventures — the data center division of Starwood, which oversees assets exceeding $125 billion — will manage design work, construction activities, tenant acquisition, and facility management.
Both organizations will share financing responsibilities and operational duties for the ventures.
The platform anticipates delivering more than 1 gigawatt of IT capacity during the first development phase. Future plans outline potential expansion beyond 2.5 gigawatts.
MARA will maintain the opportunity to invest up to 50% in joint venture initiatives, preserving ownership stakes in assets that produce operating cash flow.
Shifting Toward AI Infrastructure
MARA’s current facilities were primarily constructed for Bitcoin mining operations, but these sites possess something increasingly scarce and valuable: immediate access to substantial power supplies.
Tech companies currently face intense competition to obtain power resources for emerging AI infrastructure, making these locations particularly attractive.
CEO Fred Thiel characterized 2026 as “an inflection point,” referencing both the Starwood collaboration and a separate expansion agreement with Exaion to enhance enterprise AI capabilities.
This strategic direction places MARA within a growing group of bitcoin miners redirecting their infrastructure toward AI and high-performance computing applications. Bitfarms (BITF) underwent a recent rebrand to Keel Infrastructure as part of a comparable transition from mining operations toward HPC and AI data center services.
The movement gained momentum following Bitcoin’s latest halving event, which reduced miner rewards by half. Power costs have climbed while bitcoin prices have declined, and intensified competition has compressed margins throughout the mining industry.
Bitcoin Remains Strategic Priority
The company maintains its commitment to bitcoin operations alongside this new direction.
MARA continues to view cryptocurrency as central to its business model.
Thiel made explicit statements in his Q4 shareholder letter affirming that “Bitcoin remains a core pillar of MARA’s strategy,” emphasizing that the company’s long-term confidence in the asset class continues unchanged.
These remarks accompanied challenging quarterly financial results.
MARA disclosed Q4 GAAP EPS of -$4.52, falling short of Street consensus by $3.35. Revenue totaled $202.3 million, representing a 5.6% year-over-year decline and missing analyst estimates by $49 million.
The quarter’s net loss reached $1.7 billion, contrasting with net income of $528.3 million during Q4 2024. The majority of this loss — $1.5 billion — resulted from a decrease in the fair value of digital assets maintained on the company’s balance sheet.
Adjusted EBITDA registered negative $1.5 billion, compared with a positive $796 million during the corresponding quarter one year prior.
MARA attributed the revenue reduction to a 14% decrease in the average price of bitcoin mined throughout the quarter.
The company operates from its headquarters in Hallandale Beach, Florida.
