StockSpill — track superinvestor 13F holdings, congressional stock trades, and insider buys

The archetype. Concentrated, rarely trades, holds for decades. Any new buy is massive news.

Former OpenAI researcher who built a hedge fund around one idea: AGI is arriving by 2027 and markets haven't priced it in. Bets on the infrastructure of AI — power, compute, silicon — not the models themselves. Grew to $5.5B in disclosed long equity exposure in under 18 months.

The man who broke the Bank of England. Global macro legend who bets on reflexivity — the idea that market participants' perceptions shape the fundamentals they're trying to measure. Massive, fast, and fearless.

Concentrated activist investor who takes massive public positions and fights loudly for change. High-conviction, long holding periods, not afraid to be wrong loudly.
