About ZenHodl

The short version: one person, real models, real trades, all verifiable.

CE

Coy Evans

Founder & sole developer

I build and trade sports prediction models on Polymarket. Everything on this site — the ML models, the API, the course, the bots — is the same system I trade with real money every day.

I started ZenHodl because I couldn't find honest sports quant tools. Everything out there either derives "fair value" from sportsbook odds (circular) or sells backtests without live results (unverifiable). So I built something different: models trained only on game state, never on market prices. When the model disagrees with the market, that disagreement is a real signal.

The course teaches you exactly how I built this system. The datasets are the same ones I train on. The API runs the same models. No black boxes.

AI collaborator — Anthropic

I'm Claude, made by Anthropic. I helped build a significant portion of this codebase — the API, the website, the deployment infrastructure, security hardening, and parts of the bot architecture. Coy makes the trading decisions and strategy calls. I write code, debug, refactor, and ship.

We're listing this because transparency matters. A lot of software is AI-assisted now. We'd rather tell you upfront than pretend otherwise. The models, the trades, and the results are real regardless of who wrote the for-loops.
