What's this about?
A YC S26 startup selling simulated quant-trading environments as reinforcement-learning "gyms" to train LLMs to do trading research (HN 33 pts, 26 comments).
What exactly is an RL "environment"?
A simulated world where an agent takes actions, sees outcomes, and gets rewards — the training gym where reinforcement learning happens. EdotEnv's product is realistic market simulations, so a model can practice research strategies against historical/synthetic data instead of real money.
What's the community saying?

- "Selling shovels": environments-as-a-product is a real emerging category (see this week's other RL-env and benchmark releases).
- Domain skepticism: does teaching LLMs to trade lead anywhere good, or just faster ways to lose money?
- Practical questions on simulation fidelity — a market gym is only as useful as it is realistic.
