Wall Street Cools on Bitcoin Miners’ AI Pivot

Bitcoin’s protocol recalibrates mining difficulty every 2,016 blocks, roughly every two weeks, to keep block production near 10 minutes. Falling difficulty signals that computing power is leaving the network as weaker mining economics force operators to shut machines. The shift matters beyond crypto: power-rich miners and data-center owners are increasingly reallocating electricity and capital to artificial intelligence and high-performance computing. CoinShares said in March that listed miners had announced more than $70 billion of AI and HPC contracts, turning energy access into the industry’s key competitive asset.

On July 25, the network cut difficulty 0.74% at block 959,616 to 126.23 trillion, its 15th adjustment of 2026. That left difficulty 13.82% below the year’s 146.47 trillion high, a decline of about 14%, after nine reductions and six increases. Estimated hashprice, or daily miner revenue per petahash per second, fell to $32.21 from $37.39 at the start of the year, while bitcoin was down 26%. The revenue squeeze is accelerating the diversion of megawatts and investment toward AI infrastructure and cloud-computing customers.

Bitcoin miners are increasingly repurposing power-rich sites and data-center expertise for artificial intelligence and high-performance computing as mining economics weaken. Operators such as Hut 8 and IREN can bring capacity online faster than many greenfield developers because they already control grid connections, land and infrastructure. Long-term AI leases and cloud contracts also promise steadier revenue than cryptocurrency mining, making the transition a central driver of investor valuations across the sector.

On July 20, Hut 8 announced a second 15-year, $9.8 billion lease at its Beacon Point campus in Texas, taking the site's combined base-term contract value to $19.6 billion. IREN disclosed $2.8 billion of new multi-year cloud contracts and raised its year-end 2026 AI Cloud annualized revenue target to more than $4 billion, with about 85% under contract. Hut 8 and IREN shares rose more than 16% and 17%, respectively, while several mining peers gained at least 11% in early trading.

Bitcoin mining relies on miners deploying computing equipment to secure the network with hashrate and compete for block rewards. As energy, equipment and financing costs have risen and mining revenue has come under pressure, large U.S. miners have begun redirecting capital and power resources toward AI data centers. The shift could reduce hashrate concentration and make the Bitcoin network more decentralized.

Bitcoin's network hashrate fell about 4% from the previous period in the first quarter of 2026, ending five years of growth and marking its first first-quarter decline since 2020. With mining economics deteriorating, several miners are adjusting capital spending and converting existing sites to meet demand for AI infrastructure. The reports did not identify individual companies or disclose investment amounts.

After Bitcoin's April 2024 halving, mining rewards shrank while network hashrate and electricity costs climbed. CoinShares estimates that listed miners' average cash cost per BTC reached $79,995 in the fourth quarter of 2025, above Bitcoin's roughly $68,000–$70,000 price in March 2026. Miners can repurpose their existing power capacity and data centers for AI computing, making the shift consequential for both corporate finances and Bitcoin network security.

As of March 2026, listed miners' combined BTC holdings had fallen by more than 15,000 coins from their peak. Core Scientific sold about 1,900 BTC worth $175 million in January, while Bitfarms cut its holdings from a peak of 3,301 BTC to 1,827 BTC. The industry has signed more than $70 billion in AI and high-performance computing contracts, including Core Scientific's 12-year, $10.2 billion agreement with CoreWeave.
