The largest US Bitcoin miner is betting that flexible power — switching between mining and AI workloads — will define the next phase of digital infrastructure.
MARA Holdings agreed to pay as much as $600 million for a 1,200-acre Texas site, converting a planned green fuel plant into a flexible power campus for Bitcoin mining and artificial intelligence tenants.
"Power is the scarce input in AI," Fred Thiel, chairman and chief executive officer of MARA, said in an April filing. "We are building a differentiated platform designed to maximize the value of every megawatt we control."
The site in Matagorda County, about 145 kilometers southwest of Houston, comes with secured grid rights for up to 2 gigawatts — approvals that can take years to obtain. MARA expects access to an initial 1 GW by October 2027 and the full 2 GW by April 2028, subject to ERCOT approval. The staged payment structure ties most of the $600 million to regulatory approvals, land purchase, and execution of a data center lease with a third-party tenant. HIF Global, the low-carbon fuel developer that originally planned an e-methanol plant on the site, will retain a minority stake.
The acquisition is the latest in a series of major infrastructure moves by MARA. The company is also acquiring the 505-megawatt Long Ridge gas plant in Ohio for about $1.5 billion and has partnered with Starwood Capital Group to develop roughly 1 GW of AI data center capacity. Combined, MARA's potential portfolio could reach about 4.8 GW — more than double its current footprint.
Why flexible power wins
The strategic logic hinges on a simple operational advantage: Bitcoin mining machines can power down in seconds, while a fuel plant or traditional data center must run continuously. That flexibility lets MARA mine Bitcoin when hashprice is favorable — currently at $29.6 per PH/s per day, according to Hashrate Index — and redirect power to AI tenants during peak demand periods or when mining economics deteriorate.
The approach is gaining traction across the sector. Riot Platforms has sold Bitcoin to fund its own data center pivot and signed a 10-year lease with Advanced Micro Devices at its Rockdale facility. Hut 8 secured a 15-year lease valued at roughly $7 billion for its River Bend AI data center campus. Cipher Digital, formerly Cipher Mining, has signed leases with Amazon Web Services and Google for a combined 600 MW of high-performance computing capacity.
The $4.8 billion question
MARA's expansion comes as the industry faces severe pressure on mining profitability. Bitcoin has traded below the cost of production for some miners, JPMorgan analysts said in June, and hashprice remains near historic lows. The company's ability to convert its growing power portfolio into signed tenant leases — rather than relying solely on Bitcoin mining revenue — will determine whether the strategy pays off.
MARA held more than $900 million in Bitcoin on its balance sheet as of recent prices, an asset base that can help secure financing for capital-intensive data center development. The company's price-to-book value stands at 3.5 times, compared with 7.9 times for Hut 8, suggesting the market is pricing MARA's infrastructure pivot at a discount to some peers.
The Matagorda site is expected to begin construction this year, with first power delivery targeted for October 2027. MARA said there is already interest from potential tenants in high-performance computing.
