Breaking: OpenAI fired Leopold Aschenbrenner at 22. Three years later, he manages $5.5 billion

His next 13F files this Friday and the new trades will be posted here

Leopold is quickly becoming one of the best AI investors out there

And it started when he got fired from OpenAI in April 2024 for a leaked memo on AI safety

Instead of moving on, he spent 6 months writing a 165-page document predicting AGI arrives by 2027

Then he launched Situational Awareness LP. Backed by the founders of Stripe and the former CEO of GitHub

Here's what he bought:

• Bloom Energy (BE): powers AI data centers. Up ~1,420%

• Lumentum (LITE): optical components connecting AI chips at scale. Up ~1,335%

• SanDisk (SNDK): storage layer for AI workloads. Up ~3,130%

• CoreWeave (CRWV): GPU cloud for AI training and inference. Up ~166%

• Iris Energy (IREN): AI-focused compute infrastructure. Up ~585%

Every AI model that gets built needs power, somewhere to store data, and compute to run on. He bought all three before anyone else was paying attention

Breaking: Michael Burry says he knows people see him as “the boy who cried wolf.”

But he correctly predicted:

• 2000 Dot Com Crash

• 2008 Housing Crash

• 2021 Meme Stock Collapse

• 2023 Bank Stock Run

Now he says the current stock market feels like the last few months of the Dot Com Bubble

IBM built the greatest machine in history, won $500,000,000, stock hits all-time high, then they turned it off

29 years ago today, Deep Blue was created to surpass humans

Deep Blue was a supercomputer that evaluated 200 million chess positions per second. IBM built it for one purpose: beat Garry Kasparov, the reigning world champion since 1985

Timeline:

• 1996: Kasparov beats Deep Blue 4-2. IBM goes back to the lab

• 1997: IBM rebuilds it from the ground up

• May 11, 1997: Deep Blue wins the rematch. Kasparov resigns in 19 moves

• Next Day: $IBM(IBM.US) stock jumps to a 10-year all-time high

• Kasparov accuses IBM of cheating and demands another rematch

• IBM refuses, shuts the project down, and retires Deep Blue to the Smithsonian

Nobody knew it then, but this was the first time a machine proved it could outthink a human

Never in history has the S&P 500 been carried by fewer stocks

Right now, only 42 of 500 are responsible for pushing the market higher

Historically, that number sits around 100

And those 42 are being led by just 5:

• Alphabet $Alphabet(GOOGL.US)

• Nvidia $NVIDIA(NVDA.US)

• Amazon $Amazon(AMZN.US)

• Broadcom $Broadcom(AVGO.US)

• Apple $Apple(AAPL.US)

Every other time the market got this top-heavy, a pullback followed

The last time it looked like this: the Dot-Com Bubble in 2000

62 years ago today, someone cheated Warren Buffett so he took his entire company

At the time, Buffett was just a minority shareholder in Berkshire Hathaway with a simple plan: buy cheap and sell high.

But that's not how things turned out

In 1964, Berkshire's chairman Seabury Stanton verbally agreed to buy Buffett out at $11.50 per share. Then the letter arrived and it said $11.375. Twelve and a half cents short

Buffett didn't sell. Instead, he bought every share he could find

Timeline:

• 1962: Buffett buys into a dying New England textile mill at $7.50/share

• 1964: Stanton asks Buffett his price. Buffett says $11.50. Stanton shakes on it

• May 6, 1964: The letter arrives at $11.375. Buffett gets furious and starts buying everything he can

• 1965: Buffett owns 38% of the company and takes control. Stanton is out

• 1967: Berkshire buys its first insurance company, National Indemnity, for $8.6M. The pivot begins

• 1985: The last textile mill closes. Berkshire is now a holding company

• Today: BRK-A at $703,435/share

Stanton tried to save $28,125 and ended up losing the whole company
