I'm using GPT5 Pro to find me the best stocks and startup investments. Asked it to use modern portfolio theory and size investments. —Top Privates [+9.7%]: Databricks, Stripe, Anthropic, SpaceX —Top Publics [+14.2%]: Nvidia, TSMC, Microsoft, Meta Just put $1000 into the stocks!

Prompt: "Check all public / private stock market companies and tell me what I should invest in from first principles reasoning. You have $1000. Please do deep research and present rationale for each investment. Each one should have a target price and expected value. Use advanced math for trading. Draw research from authoritative sources like research and unbiased pundits. Size my bets properly and use everything you know about portfolio theory. Corroborate each decision with a list of predictions about those companies. Your goal is to maximize expected value. Make minimum 5 investments. Write it in a table."

This follows my previous experiment on Polymarket, which seemingly had ~2-4x the expected returns!

(this is just an experiment, I'm aware of the many many flaws with this, but it sets a new baseline)
