Public Bitcoin miners cut hashrate 13.4% as AI revenue grows
Public Bitcoin miners cut realized hashrate 13.4% over six months to 319 EH/s, outpacing the network's 10.6% decline, as operators shift power to AI data centers. Core Scientific and TeraWulf now generate majority revenue from colocation and HPC leases, signaling sector evolution beyond crypto.
Quick Take
Public miners' realized hashrate fell 13.4% to 319 EH/s in Q2 2026.
Core Scientific and TeraWulf now earn majority revenue from AI colocation/HPC.
Bitdeer bucked trend, boosting hashrate 44% to 63 EH/s.
Network hashrate declined 10.6%, slower than public miner pullback.
Market Impact Analysis
NeutralThe reported hashrate reduction and revenue shift are structural business developments for public miners rather than direct crypto price catalysts, yielding no clear bullish or bearish market impact.
Speculation Analysis
Key Takeaways
- Public miners' realized hashrate fell 13.4% to 319 EH/s in Q2 2026.
- Core Scientific and TeraWulf now earn majority revenue from AI colocation and HPC.
- Bitdeer bucked the trend, boosting hashrate 44% to 63 EH/s.
- Network hashrate declined 10.6%, slower than the public miner pullback.
What Happened
Public Bitcoin miners cut realized hashrate by 13.4% over six months, dropping from 368.3 EH/s in Q4 2025 to 319 EH/s in Q2 2026. The decline outpaced the network's 10.6% fall, indicating a deliberate shift in strategy. Core Scientific and TeraWulf now generate the majority of revenue from colocation and HPC leases, not mining. This marks a structural evolution as operators repurpose power toward AI data centers. The contraction reflects a strategic reallocation rather than a simple drop in network activity.
The Numbers
Excluding Bitdeer, the cohort's hashrate fell 21.2% to 255.9 EH/s. Bitdeer diverged, increasing realized hashrate 44% to 63 EH/s. Core Scientific reported $136.7M in colocation revenue versus $27.5M from mining. TeraWulf posted $31.9M in HPC lease revenue compared to $12.8M from mining. These figures underscore the revenue shift from block rewards to AI infrastructure services. The divergence between Bitdeer and its peers highlights a split in strategy within the mining sector.
Why It Happened
Weaker mining profitability and surging demand for AI infrastructure since 2022 prompted miners to repurpose power capacity. The post-China mining ban expansion cycle led to overcapacity relative to mining economics. As Bitcoin's halving reduced block rewards, AI data centers offered more stable, higher-margin revenue. Public miners with access to power and data center expertise pivoted accordingly. This pivot mirrors broader trends where crypto-era infrastructure finds new use cases in AI.
Broader Impact
This shift reduces public miners' direct exposure to Bitcoin price swings. It also transforms them into hybrid infrastructure providers, competing in the AI compute market. The trend could accelerate as AI demand outpaces crypto mining returns. Energy grids may see more load dedicated to data centers than hashing. For investors, this may mean lower beta to Bitcoin and new valuation metrics tied to data center cash flows.
What to Watch Next
- Monitor whether smaller miners follow the AI pivot or remain pure-play mining.
- Track Bitdeer's continued hashrate expansion and its impact on mining market share.
- Watch quarterly revenue breakdowns for Core Scientific and TeraWulf for further diversification signals.
