ProPetro Holding Corp. (PUMP): Leopold Aschenbrenner Remains Bullish

We just covered the From Fired Researcher to $13.7 Billion King: How Leopold Aschenbrenner Broke the Hedge Fund World and ProPetro Holding Corp. (NYSE:PUMP) ranks 27th on this list.

ProPetro Holding Corp. (NYSE:PUMP) first appeared in the 13F portfolio of Situational Awareness LP in the fourth quarter of 2025. Back then, this stake comprised a little over 910,000 shares. Filings for the first quarter of 2026 show that the fund has made no changes to this stake. The firm operates as an integrated energy services company. It offers hydraulic fracturing, wireline and cementing, other complementary energy completion services, and power generation services to oil and gas producers and non-oil and gas applications, such as general industrial projects and data centers located primarily in Texas and New Mexico. Leopold Aschenbrenner has a bullish outlook on the stock.

In recent months, ProPetro Holding Corp. (NYSE:PUMP) has quietly weaponized the Permian Basin footprint, mechanical engineering expertise, and industrial power infrastructure to transform into a major AI data center and independent microgrid power supplier. The biggest bottleneck for AI data centers is securing power generation assets, with lead times for large-scale industrial turbines stretching into years. ProPetro completely bypassed this bottleneck via a massive corporate catalyst. In April, the firm executed a strategic framework agreement with Caterpillar, locking in access to up to 2.1 additional gigawatts of advanced power generation capacity over the next five years.

While we acknowledge the risk and potential of PUMP as an investment, our conviction lies in the belief that some AI stocks hold greater promise for delivering higher returns and doing so within a shorter time frame.
