Bitcoin Miners Are Pivoting to AI and High-Performance Computing — Here's Who Is Making the Biggest Moves

Top 10 publicly traded Bitcoin miners by market cap. Source: Bitcoinminingstock.ioAs Tether builds deeper into Bitcoin mining infrastructure, the miners themselves are increasingly looking beyond Bitcoin for revenue. The pivot toward artificial intelligence and high-performance computing has accelerated significantly in 2026, with publicly traded miners redirecting power capacity and data center infrastructure toward AI workloads that offer more predictable revenue than mining in a post-halving environment. CoreWeave was one of the earliest to make this shift, transitioning from crypto mining to cloud and high-performance computing beginning in 2019, and the model it established has since been followed by Riot Platforms, HIVE Digital, MARA Holdings, TeraWulf, and Cipher Mining among others.
The capital commitments being made in 2026 signal that this is no longer an exploratory trend — it is a full strategic pivot for the largest players. Core Scientific announced plans to raise $3.3 billion through senior secured notes to fund data center expansion and refinance short-term debt. Hut 8 revealed it is seeking to raise $3.25 billion in senior secured notes to fund a 245-megawatt AI data center in Louisiana, tied to a 15-year, $7 billion lease agreement with Fluidstack. Most dramatically, analysts from Bernstein stated on Monday that IREN — currently the largest publicly traded Bitcoin miner by market capitalization — will likely phase out its mining operations entirely over time as it scales its AI cloud business. The direction of travel across the sector is clear: the infrastructure built for Bitcoin mining is being redeployed for the AI era, and the miners who move fastest are raising billions to make it happen.
