CleanSpark Reports 10%+ YoY Bitcoin Production Growth, Advanced AI Data Center Strategy In 2025; Produced 622 BTC In December
Calendar year bitcoin production increase of more than 10% year over year
Completes year marked by strategic milestones and entry into AI data centers
LAS VEGAS, Jan. 6, 2026 /PRNewswire/ -- CleanSpark, Inc. (NASDAQ:CLSK), America's Bitcoin Miner® (the "Company"), today released its unaudited Bitcoin mining and operations update for the month ended December 31, 2025.
"December closed 2025 with continued strong operational performance across our mining operations and Digital Asset Management groups," said Matt Schultz, CleanSpark Chief Executive Officer and Chairman. "We grew bitcoin production more than 10% year over year despite ongoing network difficulty increases. Our operational strength and active monetization strategies are creating a durable foundation as we advance AI infrastructure plans in Georgia, Texas, and beyond. We are making strong progress with potential tenants and will continue pursuing strategic energy opportunities to support long-term portfolio growth."
Fast-Acting Demand Response for TVA
In Tennessee, CleanSpark briefly curbed its Bitcoin mining power consumption last month by hundreds of megawatts during one of the coldest days of the year as part of long-established flexible consumption capabilities. The Company powered down operations across 11 sites in the state within 10 minutes of the Tennessee Valley Authority's request, enabled by CleanSpark's customized communications system. CleanSpark's software team developed an integration which allows TVA to swiftly coordinate a curtailment of power including the length and volume needed to be returned to the grid in times of emergency or increased demand due to extreme weather events. This ability is called demand response and helps balance supply and demand, prevents blackouts, and reduces the need for additional power plants or infrastructure.
"This curtailment demonstrates our continued commitment to being a reliable partner to utilities and the communities in which we operate," said Scott Garrison, CleanSpark Chief Development Officer and Executive Vice President. "We take our responsibility seriously to act as good stewards by leveraging our ability to engage in demand response so our local utility partners can keep the lights on when our neighbors need it most. Our ability to respond rapidly reflects the depth of our technology, expertise, and the strength of our operational discipline. We remain focused on advancing processes that enhance efficiency and ensure our operations are fully aligned with the evolving needs of our partners."
Calendar Year 2025 Success
In addition to CleanSpark's previously highlighted achievements in fiscal year 2025, the Company closed out the calendar year with momentum that continues to accelerate its journey.
- Announced evolution from pure-play Bitcoin miner to include AI compute along with the hiring of Jeffrey Thomas as SVP of AI Data Centers
- Selected Submer as first strategic partner for AI data center expansion in North America
- Entered Texas market with acquired rights of a 271-acre site and long-term power supply agreements totaling 285 megawatts for AI data center
- Closed on an upsized $1.15 billion zero-coupon convertible notes offering, empowering CleanSpark to expand its power portfolio
