Polymarket HFT bot turns $8K into $634K
- GitHub user 0xmovez published a Polymarket Bitcoin arbitrage bot that claims to place paired orders within 20 milliseconds on 5-minute markets. - The repository says the Rust bot buys both UP and DOWN tokens at market-neutral prices, shows 53 forks and 69 stars. - The post fits a broader bot-driven Polymarket market where researchers found about $40 million in arbitrage profits.

A GitHub repository tied to 0xmovez is pitching a Polymarket Bitcoin arbitrage bot built to trade 5-minute markets in about 20 milliseconds. (github.com) The README says the bot places UP and DOWN limit orders at the same time and tries to profit when both sides fill at prices that lock in a spread. It describes the approach as market-neutral, meaning the trade does not depend on Bitcoin finishing higher or lower. (github.com) The code is written in Rust, and the repository says it checks for opportunities 50 times per second. The page also says traders need Polymarket application programming interface credentials and Polygon wallet details to run it live. (github.com) Polymarket’s own documentation shows why speed matters. The platform uses a central limit order book with offchain matching and onchain settlement on Polygon, so prices can move before slower traders react. (docs.polymarket.com 1) (docs.polymarket.com 2) On Polymarket, each share trades between $0 and $1 and represents the market’s implied probability of an outcome. A bot can scan those prices and look for moments when the combined cost of opposite outcomes is low enough to leave room for profit after fills and fees. (docs.polymarket.com 1) (docs.polymarket.com 2) That setup has already drawn automated traders in size. A 2025 research summary cited by Yahoo Finance said arbitrageurs made about $40 million on Polymarket from April 2024 to April 2025 after analyzing 86 million bets. (finance.yahoo.com) (sccgmanagement.com) The same repository page says 0xmovez last updated the project three weeks ago, and GitHub shows 53 forks and 69 stars. Those numbers suggest the code is being copied and tested, even though the page does not verify profits like the viral social posts claim. (github.com) What is verifiable is narrower than the headline. Public sources support the existence of a fast Polymarket bot, the mechanics of how it would work, and a broader market where automated arbitrage has already extracted millions.
