An independent project that brings professional-grade weather forecasting to retail Polymarket traders.

What we do

WIN Weather Bot is a desktop application for Windows that helps traders capture the spread between slow weather forecasts and fast Polymarket order books. The bot pulls 138 individual forecast model runs every day, collapses them into 4 calibrated ensemble probabilities, compares those to the live CLOB, and executes trades within sub-3 seconds when an edge appears.

Why we built it

Polymarket weather markets are systematically inefficient for one structural reason: forecast runs are released on a fixed schedule (ECMWF 19 UTC, GFS every 6 hours, etc.), but retail order flow takes 30–90 minutes to reprice. That gap is consistent, measurable and exploitable — if you have the same data the institutional desks have, at the same latency. Our software puts that data pipeline in reach of every individual trader.

How we are funded

We are fully self-funded. No VC investors, no external shareholders. The company is bootstrapped by subscription revenue from its users. This means we answer to one constituency only: the people who actually use the bot.

Who we are

WIN Weather Bot is operated from Italy. The team is small and intentionally so — software development, ensemble research, customer support and infrastructure are handled by a tightly knit group with backgrounds in quantitative trading, meteorology and software engineering.

What we are not

We are not affiliated with, endorsed by, or partnered with Polymarket, Polymarket Holdings, Blue Sky Trading or any of their affiliates. We are an independent third-party tool that interoperates with the Polymarket API exactly the way any other client would. The Polymarket trademarks belong to their respective owners. See the full legal disclaimer for details.
