Requires a Polymarket wallet private key and proxy wallet address, simulated trading is safe, but real funds are at risk if run live with a funded wallet.
This project is a trading bot that looks for mispriced weather bets on Polymarket, a prediction market platform where people trade on the outcome of real world events. The bot reads official weather forecasts from the National Weather Service, compares them to the prices being offered on Polymarket's temperature markets, and uses a betting strategy called the Kelly criterion to decide how much to wager when it spots a market where the price does not match what the forecast suggests. Trades are simulated and logged to a local file so you can review performance before risking real money. To run it, you install its dependencies with npm and create a configuration file holding your Polymarket wallet credentials, along with settings like how far a price has to be off before the bot acts, how many trades it makes per run, and which cities it should watch. The bot checks on startup that your wallet credentials look valid before doing anything else. Once built, it can be run in a paper mode that only shows signals without trading, a simulated live mode that trades against a starting balance to track hypothetical profit and loss, or set to run automatically on a repeating timer. A small local dashboard is included that reads the simulation results and displays them in a browser. The readme also mentions a separate paid version of the bot with more advanced risk controls, broader market coverage, and deeper monitoring, available by contacting the author directly through Telegram. The free version described in this repository does not state a specific software license for its code.
A TypeScript bot that compares National Weather Service forecasts to Polymarket temperature market prices and simulates Kelly-criterion trades on the mismatches.
Mainly TypeScript. The stack also includes TypeScript, Node.js, Polymarket API.
The readme does not state a specific license, so terms of use are unclear.
Setup difficulty is rated moderate, with roughly 30min to a first successful run.
Mainly developer.
