Leopold Aschenbrenner hedge fund Long on Fuel cells20 May 2026 20:24
Leopold Aschenbrenner is strongly long on fuel cell energy stocks.
Through his hedge fund, Situational Awareness LP, fuel cell energy represents his single largest bullish equity bet.
According to his Q1 2026 13F filing, his absolute top long position is fuel cell manufacturer Bloom Energy (ticker: BE), holding roughly 6.5 million shares valued at $879 million, plus an additional $55 million in call options. Furthermore, he recently disclosed a brand new 10-million-share long position in another fuel cell play, T1 Energy.
The Investment Thesis: "Electrons over Chips" Aschenbrenner—a former OpenAI Superalignment researcher—built his fund around the macro thesis outlined in his famous Situational Awareness essay: the true looming bottleneck for the AI boom isn't chip design, but physical power infrastructure.
His heavy long positions in fuel cells fit into a highly targeted strategy:
Grid Avoidance: Standard utility grid connections for massive AI data centers can face backlogs and waitlists lasting years.
On-Site Power: Solid-oxide fuel cells (like Bloom's) can be deployed directly next to a data center to provide independent, 24/7 continuous power in a fraction of the time.
The "Barbell" Hedge: Strikingly, while he is aggressively long on fuel cells, clean energy, and physical infrastructure, he has heavily shorted the chip sector (holding billions in put options against NVIDIA, AMD, and Broadcom). He is betting that the AI trade is rotating downstream away from overvalued chipmakers and toward the energy providers that actually feed them.
To round out this energy thesis, his fund also holds long positions in natural gas producers (like EQT Corp) to supply the fuel cells, alongside heavily permitted Bitcoin miners being repurposed for their grid capacity.
