CleanSpark (NASDAQ: CLSK) is a publicly traded Bitcoin mining company that grew from a microcap energy company into one of the top-5 public Bitcoin miners by hash rate through an aggressive acquisition and scaling strategy between 2020 and 2024. Originally focused on energy management software, CleanSpark pivoted to Bitcoin mining in 2020 and has since built major facilities across Georgia and Wyoming, with a stated focus on using sustainable and low-cost energy sources.
Background
CleanSpark was incorporated in 2014 as an energy technology company focused on microgrids and energy management software. Under CEO Zach Bradford, the company made a strategic decision in late 2020 to enter Bitcoin mining as Bitcoin’s value proposition aligned with its interest in energy management. CleanSpark has since sold its legacy energy business and fully committed to Bitcoin mining operations.
Growth Strategy
CleanSpark’s rapid scaling has been driven primarily by facility acquisitions — buying existing mining facilities and expanding their capacity — rather than greenfield development. Key acquisitions include Bitcoin mining facilities in Georgia (multiple sites) and a large Wyoming facility. This approach allowed faster scaling than competitors who primarily built from the ground up.
Sustainability Claims
CleanSpark markets its mining operations as more environmentally friendly than industry averages by:
- Sourcing a significant percentage of power from renewable sources (nuclear, hydroelectric)
- Publishing carbon intensity disclosures and sustainability reports
- Targeting low-cost, low-carbon power contracts
Key Stats (as of 2024)
- Hash rate: 50 EH/s+ (top-5 public miner)
- Miners: 170,000+ deployed
- Facilities: Georgia, Wyoming
