Major publicly traded Bitcoin mining firms are pivoting toward artificial intelligence, causing their collective crypto output to plummet by 47% year-over-year. Despite this capital migration into over $50 billion in AI leases, the total Bitcoin network hash rate has staged an 11.7% recovery from its August 6 low.
Public Miners Pivot Over $50B to High-Performance Computing
According to a report by CryptoQuant, five prominent listed mining companies—IREN, Core Scientific, Bitfarms, TeraWulf, and Cipher—produced only 7,075 BTC this year, down from 13,263 BTC during the equivalent period in 2025. IREN, Core Scientific, and TeraWulf each experienced production declines exceeding 50%, while Bitfarms dropped 49% and Cipher decreased by 18%.
These five entities have executed more than $50 billion in AI and high-performance computing (HPC) deals. IREN signed a $9.7 billion agreement with Microsoft and plans to decommission its primary mining fleet by the end of the year. Concurrently, Core Scientific secured power allocation contracts with CoreWeave and AMD, while TeraWulf and Cipher reallocated infrastructure to third-party AI clients.
Hash Rate Bounces 11.7% as Private Competitors Fill the Gap
Despite a major capacity drop, the network's hash rate has demonstrated remarkable resilience. After plunging over 18% from its November 2025 peak to below 900 EH/s on August 6—its sharpest drawdown since the 2021 Chinese ban—the hash rate has rebounded 11.7%, putting it less than 9% off its all-time high. Over half of this gain materialized within the first three weeks of October.
While an estimated 35 EH/s exited the network from AI-focused public miners, the ecosystem absorbed a net addition of 105 EH/s since August. Private miners, state-backed entities, and international operators deploying next-generation hardware filled the deficit. Additionally, pure-play Bitcoin operators like MARA, CleanSpark, Riot, HIVE, and American Bitcoin raised their combined output by 16% year-over-year, bolstered by Bitcoin's price recovery back above $80,000.
Key Takeaways
- AI Pivot: IREN, Core Scientific, Bitfarms, TeraWulf, and Cipher cut BTC output by 47% (from 13,263 to 7,075 BTC).
- High-Value Contracts: AI/HPC lease commitments top $50 billion, led by IREN’s $9.7 billion deal with Microsoft.
- Network Recovery: Hash rate rebounded 11.7% from its 900 EH/s August 6 trough, driven by 105 EH/s in fresh capacity.
- Pure Miners Gain: Competitors such as MARA, CleanSpark, Riot, HIVE, and American Bitcoin boosted production by 16%.
Why It Matters
The massive migration of public mining infrastructure toward AI illustrates how power access has become the single most valuable commodity in digital infrastructure. While bears warned that corporate departures would weaken network security, the fungible nature of hash rate has proven that private capital and international operators will swiftly step in when mining profit margins stabilize. As long as Bitcoin remains north of $80,000, specialized AI hosting and dedicated BTC mining will comfortably coexist without compromising protocol security.
