CleanSpark Inc. (NASDAQ:CLSK) surged 22.38% in after-hours trading following announcements about its strategic shift toward AI infrastructure. The stock’s rally coincided with news that CleanSpark is expanding its data center operations in Texas and securing up to 890 megawatts of utility-scale power capacity in Houston, signaling a pivot from Bitcoin mining to high-growth AI infrastructure. CEO Matthew Schultz highlighted progress in transitioning the company into a digital infrastructure and data center development firm, emphasizing "strong momentum" at its Sandersville site and plans for additional capacity. While Cantor Fitzgerald and H.C. Wainwright recently lowered price targets due to Bitcoin mining challenges and wider Q1 losses, analysts maintained Overweight/ Buy ratings, citing AI-related catalysts as a key upside driver.
