A Silicon Valley wonderkid who built a $45 billion hedge fund by the age of 24 has seen his company unravel just days before his wedding.
Leopold Aschenbrenner’s Situational Awareness fund’s assets have dwindled to an estimated $10 billion after borrowing too much money for AI bets, according to the Wall Street Journal.
Aschenbrenner has for the last two years been considered the oracle of AI, after penning a manifesto about the future of the industry which went viral on the internet and rapidly became required reading in the tech world.
The 2024 essay gained praise from the president’s daughter, Ivanka Trump, while any skeptics of the then-22-year-old were promptly silenced by the success of Situational Awareness.
Everything appeared to be falling into place for the young German-born hedge funder as he lived a life of luxury with his fiancée, Avital Balwit, the chief of staff to the CEO of Anthropic, in their San Francisco mansion.
Aschenbrenner’s honey-gold hair and distinctive monochrome turtlenecks bolstered his image as what one columnist dubbed the reclusive ‘Nostradamus of AI,’ and he quickly accrued a cult following in investor circles.
But the dream came crashing down just as the financial power couple were poised to tie the knot at a lavish ceremony in California this week.
Situational’s fortunes suddenly reversed after its highly leveraged AI investment strategy fell apart. These positions spectacularly backfired when the sector weakened this year.

Falling share prices triggered margin calls from lenders, forcing emergency asset sales that pushed losses even deeper. The resulting liquidity crunch created a self-reinforcing spiral, transforming a market downturn into a full-blown crisis.
Now, as guests gathered in the picturesque seaside town of Carmel for Aschenbrenner’s lavish multi-day wedding celebration, instead of preparing to tie the knot, the Wall Street investor has been scrambling to save his business empire.
Aschenbrenner had planned an extravagant event complete with a Tuscan-style villa ceremony, a luxury forest spa finale and even a pre-wedding intellectual conference where guests would debate the future of AI.
He has instead been rushing to raise cash to meet lender demands, by appealing to some of the world’s biggest hedge funds and selling billions of dollars in holdings to Ken Griffin’s Citadel.
In a letter to his investors on Thursday, Aschenbrenner promised to focus on risk management in future ‘to ensure a higher level of resilience going forward,’ according to the Wall Street Journal.
‘I take full responsibility for these events,’ he reportedly wrote.
The Berlin-born entrepreneur’s rise was meteoric, starting from his early teens when he skipped several grades, graduating high school in Germany at just 15 years old.
He made his way to the US to study computer science at Columbia University, where he graduated as valedictorian at the age of 19.
Aschenbrenner met his fiancée Balwit when they were both young protégés of Sam Bankman-Fried, working for the philanthropic arm of his crypto exchange FTX.
When FTX collapsed, Aschenbrenner joined OpenAI, where he worked in its AI Superalignment team which is responsible for imposing limits on the technology to ensure it does not go rogue and destroy humanity.
He was fired after less than a year for allegedly leaking information to Holden Karnofsky, the husband of an Anthropic executive, in 2024. Aschenbrenner disputes the OpenAI narrative and has insisted he was axed after penning a memo exposing concerns over alleged security gaps at the company.
Soon after his firing, Aschenbrenner wrote his now-infamous 165-page essay, ‘Situational Awareness: The Decade Ahead,’ which predicted the future of AI.

The manifesto stated that AI systems would match or exceed human capabilities by 2027, and reach the status of ‘superintelligence’ by 2030. Aschenbrenner claimed that he was among an elite number of people with a clear view of the future.
‘Right now, there are perhaps a few hundred people, most of them in San Francisco and the AI labs, that have situational awareness,’ he wrote. ‘Through whatever peculiar forces of fate, I have found myself among them.’
After going viral and capturing the attention of Ivanka Trump among hundreds of thousands of other fans, he used the manifesto to raise money for his hedge fund.
His portfolio of investors was impressive – comprising the likes of Patrick and John Collison, the brothers who co-founded payments firm Stripe, along with top AI executives at Meta.
He purchased a mansion in San Francisco’s patrician Nob Hill neighborhood, living close to OpenAI CEO Sam Altman, while his early success turning millions into billions earned him a cult following.
This year, podcaster Tim Ferriss dubbed Aschenbrenner ‘the Nostradamus of AI,’ adding that his viral paper was ‘as close to clairvoyant as you could possibly be.’
However, the vulnerabilities in Situational’s business model were exposed this week.
For every dollar invested, Aschenbrenner reportedly borrowed another three or four dollars – sometimes even more – creating huge exposure to any downturn in the AI sector.
When enthusiasm for AI stocks began to cool this month amid concerns over cheaper Chinese models and questions about future profits, the strategy quickly turned toxic.

Banks issued margin calls.
Rival hedge funds reportedly began sharing information about Situational Awareness’ positions, with some even placing bets that the fund’s favourite stocks would continue falling as it was forced to sell.
The pressure snowballed.
As losses mounted, Aschenbrenner considered increasingly dramatic options, including selling one of his most valuable assets – a $3.5 billion stake in AI giant Anthropic.
Late on Wednesday night, a deal was reportedly struck with investors led by Greenoaks and Sequoia Capital.
By morning, he had changed his mind.
Instead, the fund dumped large portions of its public stock portfolio to repay lenders while holding on to its private investments.
The Daily Mail has reached out to Aschenbrenner for comment.
