BioTradingArena – Benchmark for LLMs to predict biotech stock movements
Hi HN, My friend and I have been experimenting with using LLMs to reason about biotech stocks. Unlike many other sectors, Biotech trading is largely event-driven: FDA decisions, clinical trial readouts, safety updates, or changes in trial design can cause a stock to 3x in a single day (https://www.biotradingarena.com/cases/MDGL_2023-12-14_Resmet...). Interpreting these ‘catalysts,’ which comes in the form of a press release, usually requires analysts with previous expertise in biology or medicine. A catalyst that sounds “positive” can still lead to a selloff if, for…
BioTradingArena – Benchmark for LLMs to predict biotech stock movements launched on February 6, 2026 with 35 votes, #639 of 16,627 launches that month and more than 95% of that year's launches.
In plain words
BioTradingArena is a benchmark tool for evaluating how well large language models can interpret biotech stock catalysts—events like FDA decisions and clinical trial results that drive significant price movements. It is designed for researchers and developers working with LLMs who want to test their models' ability to reason about complex medical and scientific information in financial contexts. The tool addresses the challenge that biotech catalysts require specialized expertise to interpret correctly, as seemingly positive news can trigger selloffs if results disappoint on effect size, patient populations, or approval probability.

An open benchmark for evaluating how well LLMs reason about clinical trial results, FDA decisions, and biotech catalysts — and predict the stock price reaction.
Configure and run benchmark strategies against the oncology dataset. Edit prompts to experiment with different approaches. See API to run the benchmark yourself and create your own custom strategies. Single-prompt categorical prediction (very_negative to very_positive).

I've been using AI to analyze every supplement on the marketJan 2026 · pillser.com · ▲94Hey HN! This has been my project for a few years now. I recently brought it back to life after taking a pause to focus on my studies. My goal with this project is to separate fluff from science when shopping for supplements. I am doing this in 3 steps: 1.) I index every supplement on the market (extract each ingredient, normalize by quantity) 2.) I index every research paper on supplementation (rank every claim by effect type and effect size) 3.) I link data between supplements and research papers Earlier last year, I took pause on a project because I've ran into a few issues: Legal: Shady…
Read the Tape – Wordle for daytrading, five blind S&P 500 charts a dayJul 2026 · readthetape.cc · ▲70Read the Tape gives players the same 5 S&P500 stock charts per day to predict.

Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
