MARA Sells Over $1B in Bitcoin to Cut Debt, Fund AI Shift; Analysts See Margin Upside for Remaining Miners

A growing number of publicly listed Bitcoin miners are trimming or abandoning BTC mining to redirect capital and infrastructure toward AI data-center projects—an exodus analysts say could improve profitability for the miners that stay. This week, MARA sold 15,133 BTC worth more than $1 billion and used the proceeds to reduce outstanding debt by 30%. The company has also partnered with Starwood to develop AI data centers. Similar moves are unfolding across the sector: Bitdeer reportedly sold its entire Bitcoin holdings, while Riot has also liquidated part of its BTC to fund AI-related ventures. Analyst Billy Boone argued that AI economics are currently more attractive than Bitcoin mining for large operators. He added that the shift can lift margins for the rest of the network: as big miners take hashrate offline and fewer rigs compete, mining difficulty can fall, making block production more profitable for remaining miners. In the current cycle, network difficulty growth has been relatively subdued at about 75% as major players pivot toward AI, according to Boone. Boone also flagged a potential energy-driven catalyst. If the West Asia crisis persists into April and the Strait of Hormuz remains closed, energy prices could rise, pressuring miners reliant on oil-linked power. He said small and mid-sized miners with stable power purchase agreements (PPA's) could see one of their most favorable setups since China's 2021 mining ban. Barefoot Mining CEO Bob Burnett echoed the view that reduced concentration among public miners could lead to a healthier ecosystem, saying smaller miners were previously crowded out and that less hashrate controlled by a handful of firms would improve balance. On miner stress, Glassnode's Hash Ribbon data suggest the distress that built from late November eased earlier this month, helping reduce miner selling pressure and supporting Bitcoin's March rebound. Analysts cautioned that if BTC falls below $65,000, another wave of miner distress could emerge and renew selloffs. Final Summary Analysts see the AI pivot by public Bitcoin miners—including MARA—as potentially creating a more balanced mining landscape and improving margins for solo and mid-sized operators. Miner distress eased in early March, but a deeper BTC pullback could trigger renewed selling from miners.
