IREN Mines 1,521 BTC in January as Bitcoin Miners Race to 50 EH/s With AI and HPC Pivot

The Bitcoin mining industry kicked off 2025 with a dramatic display of scale and ambition, as IREN Limited reported mining an astounding 1,521 BTC in January alone — nearly triple its December output — while simultaneously racing to integrate AI and high-performance computing into its infrastructure strategy.

TL;DR

• IREN mined 1,521 BTC in January 2025, up from 529 BTC in December 2024, generating approximately $52 million in revenue
• The company maintained an average operating hashrate of 29 EH/s with a 75% hardware profit margin
• IREN is on track to reach 50 EH/s within five months, with direct-to-chip liquid cooling installation for AI and HPC workloads underway
• Hyperscale Data reported approximately $1.9 million in January Bitcoin mining revenue while transitioning to HPC services by September 2025
• Bitfarms engaged consultants Appleby Strategy Group and World Wide Technology to evaluate HPC and AI conversion of its North American data centers

IREN’s Explosive January Output

IREN Limited delivered what may be the most impressive January production numbers among publicly traded miners, mining 1,521 BTC compared to just 529 BTC in December 2024. The company’s average operating hashrate reached 29 EH/s as of January 25, 2025, maintaining a hardware profit margin of 75% despite rising electricity costs.

Total revenue for January came in at approximately $52 million, with the company’s efficiency metrics reflecting the benefits of its upgraded fleet and expanded capacity. Co-CEO Daniel Roberts emphasized the ongoing demand for IREN’s cloud and colocation services, particularly given the company’s strategic power portfolio positioning it for dual Bitcoin mining and AI infrastructure revenue streams.

The company is advancing two major infrastructure projects: the 1.4 GW Sweetwater Project and the expansion of the 750 MW Childress Project. IREN is installing direct-to-chip liquid cooling systems designed to support both Bitcoin mining and AI and HPC workloads, reflecting the broader industry trend of miners diversifying beyond pure cryptocurrency production.

The Mining-to-AI Pivot Accelerates

January 2025 marked a clear acceleration in the trend of Bitcoin miners repurposing their energy infrastructure for AI and HPC applications. Bitfarms explicitly announced partnerships with Appleby Strategy Group (ASG) and World Wide Technology (WWT) to evaluate its North American data centers for potential partial or total conversion to HPC and AI operations.

Bitfarms CEO Ben Gagnon framed the shift as transformational, noting that long-term HPC and AI contracts would monetize the company’s energy assets with steady cash flows and earnings streams that create a more resilient business model. The company has already pushed back construction timelines at its Sharon, Pennsylvania site from 2025 to 2026 specifically to accommodate potential HPC integration.

Hyperscale Data, Inc. also reported approximately $1.9 million in January Bitcoin mining revenue while actively transitioning its business model toward providing HPC services to power AI solutions, with a target completion date of September 2025. The company’s pivot represents the growing recognition that energy infrastructure originally built for Bitcoin mining can serve as a foundation for the AI computing boom.

Hashrate Arms Race Intensifies

The competitive dynamics of Bitcoin mining tightened considerably in January. IREN’s target of 50 EH/s within five months would place it among the largest publicly traded miners globally. Meanwhile, Bitfarms reached 15.2 EH/s by month-end, energizing new sites in Sharon, Pennsylvania and Baie-Comeau, Quebec to bring its total operating capacity to 386 MW.

HIVE Digital Technologies maintained 5.7 EH/s with plans to explode to 25 EH/s following its 200 MW hydro-powered acquisition in Paraguay. The company mined 102 BTC in January while building its HODL portfolio to 2,657 BTC valued at $271 million at month-end Bitcoin prices near $102,000.

The aggregate hashrate growth across these public miners alone represents a substantial increase in network computing power, contributing to the ongoing rise in mining difficulty that continues to pressure smaller, less efficient operators.

Staking and Validation Services Expand

The broader digital asset infrastructure landscape saw notable developments in staking services during January. Bit Digital reported approximately 21,568 ETH actively staked in native staking protocols as of January 31, earning a blended annual percentage yield that contributes to the company’s diversified revenue model spanning both Bitcoin mining and Ethereum validation.

The UK’s amended Financial Services and Markets Act, which took effect on January 31, formally separated crypto staking from the definition of a collective investment scheme, removing a major regulatory barrier for staking service providers in the British market. This regulatory clarity coincided with Japan’s Coincheck launching its Ethereum staking service on the same date, signaling growing mainstream adoption of staking infrastructure alongside traditional mining operations.

Why This Matters

January 2025 represents a watershed moment for the Bitcoin mining industry. The convergence of record Bitcoin prices above $100,000, massive hashrate expansion, and the accelerating pivot toward AI and HPC infrastructure suggests that mining companies are rapidly evolving from single-revenue cryptocurrency producers into diversified digital infrastructure providers. The companies that successfully balance Bitcoin mining profitability with AI infrastructure development will likely emerge as the dominant players in this new landscape, while those that fail to adapt risk being squeezed out by rising difficulty and operational costs. The dual revenue model — cryptocurrency production plus computing services — may define the mining industry’s future.
