We just covered From Fired Researcher to $13.7 Billion King: How Leopold Aschenbrenner Broke the Hedge Fund World and CleanSpark, Inc. (NASDAQ:CLSK) ranks 17th on this list.
CleanSpark, Inc. (NASDAQ:CLSK) first appeared in the 13F portfolio of Situational Awareness LP in the fourth quarter of 2025. Back then, this position comprised 1.6 million shares. Filings for the first quarter of 2026 show that the fund owned 12.2 million shares in the firm, up close to 650% compared to filings for the previous quarter. CleanSpark operates as a bitcoin mining company in the Americas. It also owns, leases, and operates data centers and power assets. Matthew Schultz, the CEO of the firm, said during the latest earnings call that the quarter represented meaningful progress in the evolution of the firm into a digital infrastructure and data center development company. Schultz said the company has 1.8 gigawatts of currently contracted capacity and had added 25 megawatts of contracted capacity to one of the Metro Atlanta locations last month. He also said the company was focusing on long duration leases with high-quality tenants.
CleanSpark, Inc. (NASDAQ:CLSK) has attracted the attention of Leopold Aschenbrenner in recent months. In the modern compute economy, the ultimate constraint is not chip architecture, but ready-to-plug, utility-approved power. The firm has quieted bear narratives by securing grid interconnects in premium geographic zones. In the May 2026 operational update, management confirmed that the company has officially doubled total megawatts under contract year-over-year. The core asset backing the long-term bull case is the pipeline of 585 MW of fully ERCOT-approved, utility-grade capacity in Texas. This is supplemented by a broader multi-gigawatt expansion platform distributed across institutional sites in Texas and Georgia.
