Marathon Digital (MARA) acquires Texas power site to pivot into AI data-center development, chasing higher-margin infrastructure contracts.
Bitcoin miner MARA Holdings just agreed to pay up to $600 million for a Texas power site—and bitcoin is no longer the whole point. On July 9, the Nasdaq-listed company announced that its Volt Texas LLC subsidiary had struck a deal with HIF USA for more than 1,200 acres in Matagorda County, approximately 90 miles southwest of Houston. The price, payable in stages tied to permits, site access, and a future data center lease, reveals the real ambition: MARA is moving before the customer is signed.
The site is expected to provide up to 1 gigawatt of grid capacity by October 2027 and up to 2 gigawatts by April 2028, subject to regulatory approvals. MARA plans to develop the campus with Starwood Digital Ventures for high-performance computing and bitcoin mining, with HIF USA retaining a minority interest once an HPC tenant lease is secured. This represents a fundamentally different business from traditional mining operations.
Wall Street signaled its approval immediately. MARA shares jumped almost 10% on July 9, and other miner-turned-infrastructure names moved in tandem: TeraWulf, Bitdeer, HIVE, Cipher, CleanSpark, Riot Platforms, and Hut 8. The rally reflected something more specific than a crypto surge—investors were pricing in power, land, and the possibility of long-term data center leases.
The scale becomes clearer when accounting for MARA's other moves. Once the Matagorda site energizes, it will more than double MARA's energy infrastructure portfolio to approximately 4.8 gigawatts, including its pending acquisition of Long Ridge Energy & Power—a 505-megawatt natural gas plant in Hannibal, Ohio. This acquisition reveals MARA's strategy to own more of the physical stack: generation, grid access, and the land where servers operate.
Yet 4.8 gigawatts is potential, not revenue. MARA still needs regulatory approvals, progress on interconnection, and a tenant willing to sign a long-term contract. Texas has become a magnet for data center proposals because power development moves faster than in many other markets, but ERCOT capacity remains constrained. The tension is clear: the land is valuable precisely because the grid is tight, and the grid is tight because everyone else has noticed the same thing.
The industry pivot accelerated after the 2024 bitcoin halving cut block rewards and exposed mining's weak economics. Cheap power, once a competitive advantage, has become a ticket into AI infrastructure—where hyperscale customers demand capacity they can reserve for years, not a warehouse of machines exposed to coin price volatility. TeraWulf illustrated the appeal that week by signing a 20-year data center lease with Anthropic expected to generate $19 billion in revenue. That is the kind of contract that turns a powered site into something investors can model.
Mining alone was never going to justify campuses at this scale. MARA can still mine bitcoin at Matagorda, and that matters because mining provides flexible demand between larger tenants. But the premium attaches to signed AI compute demand. A mining rig is useful; a hyperscale lease is financeable.
That is why the missing tenant becomes crucial. MARA has secured a shot at a massive powered campus in Matagorda County with Starwood Digital Ventures as a partner. It has also assumed the harder wager: turning access to electricity into contracted revenue before delays, costs, or rival sites erode the advantage. Until a lease is signed, this remains a bet—albeit a very large one.
