The history of CleanSpark: origins, milestones and its 2026 business

CleanSpark spent years developing energy and microgrid technology before making a decisive move into Bitcoin mining in 2020 through the acquisition of ATL Data Centers.

How CleanSpark developed

The company mined its first Bitcoin in December 2020 and expanded its fleet and data-centre footprint through additional acquisitions and new sites. Over time, Bitcoin mining became the dominant focus of the business.

CleanSpark in 2026

By 2026, CleanSpark operated large-scale US Bitcoin-mining infrastructure, concentrating on computing efficiency, power procurement and site development.

Why the history matters

The company’s pivot is an example of how energy-management expertise can be redirected toward power-intensive computing, although cryptocurrency mining remains exposed to Bitcoin prices, network difficulty and energy costs.
