MARA CEO Fred Thiel stated in a July 23 interview with Natalie Brunell that electricity used for artificial intelligence infrastructure generates substantially better returns than the same power devoted to Bitcoin mining. Thiel explained the gap reflects tougher mining economics driven by Bitcoin's scheduled halvings reducing block rewards while electricity remains the industry's largest operating expense. The shift is pushing Bitcoin miners to reposition themselves as data center developers, with power assets now defining competitive advantage rather than mining machines alone.
MARA Acquires Power Infrastructure Below Replacement Cost
MARA began buying sites where it had previously hosted mining equipment in late 2023 and early 2024, often below replacement cost, Thiel said. By the end of 2024, the company owned about 70% of the infrastructure supporting its operations. MARA has partnered with Starwood on a platform targeting about 1 gigawatt of near-term computing capacity, with a path beyond 2.5 GW. The company agreed in July to acquire a Texas site with access to roughly 2 GW of power for digital infrastructure. Thiel rejected the idea that AI will replace mining across MARA's portfolio, stating Bitcoin remains useful in areas with free, stranded or unusually cheap energy because it can absorb power that might otherwise go unused.
Bitcoin Miners Secure Multi-Billion Dollar AI Contracts
TeraWulf signed a 20-year lease with Anthropic for a 401 MW Kentucky campus expected to generate about $19 billion in contracted revenue. CleanSpark secured a 20-year, $6.6 billion lease for its Sandersville, Georgia, site. Hut 8 has fully contracted its 1 GW Beacon Point campus through two 15-year leases worth $19.6 billion during their base terms. IREN raised its 2026 annualized AI Cloud revenue target above $4 billion after signing $2.8 billion of new contracts.
Thiel Identifies Energy Scarcity as Core Industry Challenge
Thiel said concerns over AI facilities often stem from limited information, noting data centers require more capital, complex cooling systems, and firm delivery schedules while facing local opposition over electricity use, water, and noise. His conclusion was blunt: "At the heart of it, though, it's an issue of energy and power." For miners with grid connections and developable land, Bitcoin may increasingly become one use for electricity rather than the only one.
FAQ
What did MARA CEO Fred Thiel say about AI versus Bitcoin mining revenue?
Fred Thiel stated in a July 23 interview with Natalie Brunell that electricity used for artificial intelligence infrastructure generates substantially better returns than the same power devoted to Bitcoin mining, saying "You get a lot more money per electron if you're doing it for AI than for bitcoin mining."
