Abstract

Leopold Aschenbrenner, a 24-year-old former member of FTX’s Future Fund team and later an OpenAI employee, has become one of the most talked-about figures in AI investing. His fund, Situational Awareness LP, grew its publicly disclosed holdings from $255 million in Q4 2024 to $5.5 billion by Q4 2025—an extraordinary surge in just one year. Aschenbrenner, who graduated top of his class from Columbia University, was involved in the effective altruism movement, much like SBF. After FTX’s collapse, he joined OpenAI’s Superalignment team but was fired in 2024 over internal disagreements regarding AI safety. Shortly after, he published a influential 165-page essay on AI and the path to superintelligence, which led him to establish his AI-focused investment fund. Situational Awareness LP’s strategy is highly concentrated, with 86% of its portfolio in its top ten holdings. It focuses on upstream AI infrastructure—such as energy, computing power, and hardware—rather than application-layer companies. Notable positions include Bloom Energy (which saw a 10x gain), several Bitcoin mining firms transitioning to AI compute (like Core Scientific and Bitdeer), and a short position on Infosys, betting AI will replace IT outsourcing. Aschenbrenner’s story mirrors that of other brilliant young figures in tech and finance, but unlike SBF—now imprisoned—he has pivoted successfully into the AI boom, turning disruption into opportunity.

Have you heard of Leopold Aschenbrenner?

He is currently one of the hottest names in the AI investment circle — the 24-year-old's Situational Awareness LP fund had a publicly disclosed portfolio size of 'just' $225 million in Q4 2024, but in the disclosure for Q4 2025 released last month, this number had rapidly grown to $5.5 billion.

What few know is that Leopold Aschenbrenner was once also part of the crypto world — he previously worked for the FTX Future Fund team under FTX, until the collapse of FTX.

The AI Prodigy from a Family of Doctors

Leopold Aschenbrenner was born in Germany to parents who are both doctors.

In 2021, the 19-year-old Leopold Aschenbrenner graduated first in his class from Columbia University with dual degrees in Economics and Mathematical Statistics. During his time at Columbia, he co-founded the university's chapter of "Effective Altruism" (EA).

"Effective Altruism" was a principle often espoused by FTX founder SBF. Perhaps due to shared beliefs, Leopold Aschenbrenner joined the FTX Future Fund team in February 2022. This was a charitable initiative created by the FTX Foundation to advance effective altruism. Leopold Aschenbrenner worked in this team until just before the FTX blow-up in November 2022.

In 2023, having left FTX, Leopold Aschenbrenner turned to OpenAI, now a leading AI company, joining the Superalignment team led by luminaries Ilya Sutskever and Jan Leike. This team focused on technical breakthroughs to guide and control AI systems smarter than humans.

In April 2023, OpenAI's internal communication system was hacked, but the company did not disclose this publicly. Leopold Aschenbrenner promptly submitted a memo to the OpenAI board, arguing that OpenAI's security measures were insufficient. He later stated that this memo led to disagreements between the board and management over security issues, and he himself received a warning from HR.

In April 2024, OpenAI fired Leopold Aschenbrenner for alleged information leaks, but he countered that the so-called "leak" was actually him sharing a "brainstorming" document with three external researchers solely to solicit feedback. OpenAI claimed the dismissal was unrelated to the security memo Leopold Aschenbrenner had previously submitted, while he stated that someone explicitly told him the memo was the main reason for the firing. Just one month later, the Superalignment team disbanded, and other prominent AI researchers, including Ilya Sutskever, also left OpenAI.

Interestingly, Leopold Aschenbrenner's conflicts with OpenAI didn't end there; his fiancée, Avital Balwit, is now the Chief of Staff at Anthropic, OpenAI's biggest competitor... and FTX was also an early major investor in Anthropic.

Leaving the Tech Frontlines, Entering the Investment World

In June 2024, just two months after leaving OpenAI, Leopold Aschenbrenner wrote a massive 165-page paper titled "Situational Awareness: The Decade Ahead". The paper contained multiple chapters, predicting the emergence of Artificial General Intelligence (AGI), envisioning the path from AGI to superintelligence, describing four major risks facing humanity, outlining methods for humanity to cope with superintelligence, and expounding on the principles of "AGI Realism".

The paper "Situational Awareness: The Decade Ahead" sparked significant discussion in Silicon Valley, and Leopold Aschenbrenner's reputation soared. Subsequently, in September 2024, Leopold Aschenbrenner founded the namesake fund Situational Awareness LP and became its Chief Investment Officer, focusing on investment opportunities in the AI industry chain.

There is no public information on the initial fund size of Situational Awareness LP, but according to mainstream media reports like WSJ and Fortune in mid-2025, the fund's total assets under management (AUM) were approximately $1.5 billion at that time. LPs included Stripe's co-founders Patrick Collison and John Collison, former GitHub CEO Nat Friedman, and renowned investor Daniel Gross.

According to the 13F filings disclosed by Situational Awareness LP (a quarterly disclosure document required by the SEC for funds with AUM exceeding $100 million), in Q4 2024, Situational Awareness LP's total publicly disclosed holdings were 'only' $255 million. However, in the Q4 2025 holdings disclosure released on February 16 this year, that number had grown to a staggering $5.5 billion.

Considering that Situational Awareness LP was not long established in Q4 2024, the fund likely had some capital reserves beyond the disclosed $255 million position. But even taking the mid-2025 AUM of around $1.5 billion as the starting line, the fact that the disclosed position grew to $5.5 billion by Q4 of the same year is astonishingly fast.

Portfolio Analysis: Traces of the Crypto World Remain

Situational Awareness LP disclosed its main 29 holdings in the 13F filing; details can be seen in the chart below.

As shown, Situational Awareness LP's bets on AI are not concentrated on the more hyped application layer but are focused further upstream on the foundational infrastructure chain.

  • The top ten holdings of Situational Awareness LP account for a high 86% of the portfolio, indicating a highly concentrated strategy, primarily deployed in energy, computing power, optical communications, and storage.
  • The largest position, Bloom Energy, focuses on solid oxide fuel cell (SOFC) and electrolyzer (SOEC) technology. Driven by growing demand from AI data centers, the company's performance has consistently exceeded expectations, and its stock price has risen over 10 times since the end of 2024.
  • Hot picks like Nvidia, Microsoft, Amazon, and Google do not appear in the holdings; it seems Situational Awareness LP prefers relatively "less popular" targets.
  • The only disclosed short position by Situational Awareness LP is an options-based short on Indian software services exporter Infosys, seemingly betting that the development of Claude Code and Codex will replace traditional IT outsourcing work.

Another clue somewhat connected to the crypto world is that the holdings of Situational Awareness LP include several Bitcoin mining companies, such as Core Scientific, Cipher Mining, Iren (formerly Iris Energy), and Jihan Wu's Bitdeer.

Unfortunately, what Situational Awareness LP is evidently interested in is not these companies' direct crypto-related businesses but is betting on miners' transition into AI computing centers — in an environment where the AI trend is booming and the crypto market is sluggish, more and more mining companies are actively transforming by leveraging their existing resource advantages in land, computing power, and electricity. Here's a preview: we will have another article on this trend soon.

Diverging Paths of Fate, Reconstruction of Belief

Looking back at Leopold Aschenbrenner's career, it's hard not to think of another once-glorified young prodigy, SBF — both worked at FTX, both believed in effective altruism, and both delivered remarkable investment results. But after one misstep, SBF is now a prisoner, facing decades-long sentencing ahead. On the other hand, Leopold Aschenbrenner's life took a different fork in the road following FTX's overnight collapse, but fortunately, this seems to be a path more suited to him.

Time does not rewind, and fate never offers a chance to restart. Some are forever left in the ruins of the old era, while others are forced off their original track, only to unveil a completely new story.

As part of the Crypto industry, the thought that comes to my mind is — the industry is currently at a moment of unprecedented confidence shattering, a time of breaking and building. Some leave in disappointment, some watch hesitantly, but others are actively embracing new technological waves and narrative shifts. History often works this way; the collapse of the old story is often the birth moment of a new one. The reconstruction of belief is, in its own way, another opportunity.

Yao Shunyu's 88 Days

Yao Shunyu, a 27-year-old AI expert with a background from Princeton and OpenAI, joined Tencent in September 2025. Within 88 days, he led a major overhaul of Tencent’s AI strategy and organization, resulting in the release of Hunyuan Hy3 preview—a MoE model with 295B total parameters and 21B active parameters, supporting up to 256K context length. The launch came after Tencent leadership, including CEO Ma Huateng and President Martin Lau, openly criticized Hunyuan's earlier underperformance—citing slow development, over-reliance on superficial benchmark optimization, and poor generalization in real-world applications. Internal adoption was low, with key business units like WeChat and gaming seeking external AI solutions. Yao reshaped Tencent’s AI approach by integrating previously siloed teams, dissolving the ten-year-old Tencent AI Lab, and establishing new units focused on AI infrastructure and data. Hy3 preview was developed using co-design principles, closely aligned with product teams to ensure practical usability from the start. It has already been integrated into core products like Yuanbao, QQ, and enterprise tools. The release signals a shift from chasing rankings to building usable, scalable AI grounded in Tencent’s ecosystem. While external partnerships (like with DeepSeek and OpenClaw) helped retain users temporarily, the focus is now on making Hunyuan a reliable internal foundation. The real test lies in sustaining this new organizational momentum amid fierce competition from Alibaba, DeepSeek, and others.
