There's a new phenomenon of small groups of people who are running these small little quant funds driven by AI models who are making fuck-you returns.

I've personally seen many who are 2x'ing capital in months. Many unsubstantiated rumors also claim SSI is a quant shop too.

Well known quant funds have all tested out LLMs for trading. Some claim it doesn't work. Others， well.. what do we think Jane Street doing with their huge GPU cluster？ On top of that， there's a ton of people asking Claude / GPT what stocks to buy and/or "vibe code me a trading engine". Applies to other financial instruments too： derivatives， futures， crypto， and on the less sophisticated side， prediction masks.
