Bitcoin Miners Flee Block Rewards for Predictable Data Center Revenue

Publicly traded Bitcoin miners are rapidly pivoting away from block rewards and transaction fees toward more predictable revenue streams tied to data center colocation and high-performance computing. According to BlocksBridge Consulting, a cohort of public miners tracked by them saw their realized hashrate fall 13.4% in the second quarter of 2026 compared to the fourth quarter of 2025. This decline is even steeper when excluding Bitdeer, which saw its hashrate jump 44%, from 19 EH/s to 63 EH/s.

The divergence reflects a broader strategic split in the sector as some operators continue to bet on Bitcoin mining economics while others have concluded that their power contracts, cooling systems, and physical infrastructure are more valuable when deployed for AI workloads and cloud computing tenants. The shift is evident in the revenue mix of prominent miners like Core Scientific and TeraWulf, where non-mining activities now dominate their income.

While Riot Platforms and Bitdeer remain early in the transition, with Bitcoin mining still accounting for the majority of their revenue, the industry appears to be bifurcating between miners that have successfully converted to AI infrastructure providers and those still relying on crypto-native economics. The current capacity reduction is seen as an unwinding of the expansion cycle that followed China's Bitcoin mining ban in 2021.
