CleanSpark (CLSK) shares surged 10.67% on Monday to close at $14.42, driven by renewed investor optimism over the rapid expansion of artificial intelligence infrastructure. The catalyst was Hut 8 Corp.'s announcement of a $9.8 billion multi-year leasing agreement with an existing high-investment-grade counterparty.
