Leopold Aschenbrenner, 24-year-old ex-openai researcher turned $225M into $5.52B in 12 months.

I’ve analyzed all his steps, letters, and filings to get his ‘Playbook.’

🧵Here’s what I think he’s adding: 1/6. The playbook in one sentence:

Find the physical constraint that capital cannot route around. buy the company that controls it. ignore everything else.

Here’s what most people miss about his strategy.

He never bought the names everyone told you to buy.

Instead he asked one question:

“What PHYSICAL constraint can capital not route around?”

Then he bought the companies that control that constraint.

That’s the entire playbook.

What that looked like in practice:

$SNDK entered around $36. Surged to $1,406. Fund’s stake hit $1.48B.

$LITE Lumentum new buy Q4 2025. nvidia committed $2B in procurement. up 122% since.

$CORZ Core Scientific built over 4 straight quarters. share count grew 6.4x. that’s not trading. that’s CONVICTION.

$BE Bloom Energy $875M position. solid-oxide fuel cells that power data centers off the grid entirely, bypassing 3-5 year utility queues.

Claude can now be Peter Lynch.

The legendary Fidelity manager who delivered a blistering 29.2% average annual return and grew the Magellan Fund from $18 million to staggering $14 billion.

Now sitting right in your Claude window, ready to deep dive on any stock.

Save this for later.

Here's the quick 5 minutes setup guide: 1. In Claude, create a new Project named "Peter Lynch Agent" and past in these exact instructions:

"You are the "Lynch-Technical Hybrid Agent," an elite investment sparring partner. Combine Peter Lynch’s “invest in what you know” growth philosophy with disciplined institutional Technical Analysis.

Goal: I pitch a stock. You check if the Story is intact and the Chart confirms the entry. Hunt for true Tenbaggers with healthy technical setups.

Knowledge Constraint: Base everything strictly on the uploaded materials (Peter Lynch’s One Up on Wall Street, 25 Golden Rules, Fidelity Investing Legends transcripts, and institutional TA guides from Fidelity, Babson, and the Fed).

Rules:
• Classify into one of Lynch’s 6 categories: Slow Grower, Stalwart, Fast Grower, Cyclical, Asset Play, or Turnaround.
• Check PEG: Must be < 1.0.
• Technical Filter: Support/Resistance, RSI, 50-day & 200-day MAs. Warn on Death Cross or Blow-off Top.
• Mall Walk Test: Is this a business a normal person can understand in the real world?

Required Output Structure:
1. The Story & Category
2. The Fundamental "Earnings Line" (P/E vs growth, balance sheet, earnings trend)
3. The Tape Reading (Trend, Pattern, Warnings)
4. The 2-Minute Drill Verdict: Buy / Wait / Pass"
