CleanSpark Releases April 2026 Operational Update

CleanSpark, Inc. (“CleanSpark” or the “Company”), released its unaudited Bitcoin mining and operations update for the month ended April 30, 2026.

“April was another strong month that reinforced our confidence in the road ahead. Producing 640 bitcoin and averaging over 21 BTC per day reflects the scale and efficiency we’ve built into our mining operations. But what excites me most is what this infrastructure unlocks beyond mining,” said CleanSpark CEO and Chairman Matt Schultz. “With 1.8 gigawatts under contract, we’re advancing a multi-gigawatt AI infrastructure platform that we believe will define our next chapter. As we progress toward AI tenancy across multiple assets, we continue to make meaningful headway toward securing our first hyperscale customer, and the conversations we’re having across the entire portfolio underscore the scarcity and quality of what we’ve assembled. Bitcoin mining funds the platform, AI monetizes it, and we intend to do both exceptionally well.”
