Nothing Ever Happens: A Polymarket 'No' Trading Bot

This asynchronous Python bot automates the process of betting 'No' on non-sports markets on the Polymarket platform. It features a robust safety system to prevent accidental live trading and includes a dashboard for monitoring positions. The project is designed for easy deployment on Heroku and is released as public domain software.
Key Points
- The bot executes a specialized strategy of buying 'No' outcomes on standalone, non-sports Polymarket events.
- A multi-layered safety model requires BOT_MODE, LIVE_TRADING_ENABLED, and DRY_RUN flags to be specifically configured before real orders are transmitted.
- The system includes a built-in dashboard and recovery mechanisms to handle order transmission and state persistence.
- The project is optimized for Heroku deployment with dedicated shell scripts for lifecycle management and logging.
- The software is released under a CC0-1.0 license for entertainment purposes, with a strong disclaimer regarding financial risk.
Sentiment
The community is mostly skeptical that the strategy can generate real profits, but views the project with amusement and appreciation as a clever meme. The dominant sentiment is that efficient market theory likely eliminates any edge, though a minority argues persistent behavioral biases could create exploitable inefficiencies. There is broad consensus that the project is entertaining and well-executed even if it is not a sound financial strategy.
In Agreement
- Prediction markets systematically overprice dramatic 'Yes' outcomes because people enjoy betting on exciting events, creating a persistent bias toward No being undervalued
- The project serves as a useful open-source template for building custom Polymarket bots regardless of whether the specific strategy works
- There is empirical evidence from sports betting that 'boring' bets (unders, favorites) tend to offer better long-term returns than exciting ones due to entertainment-seeking bettors
- A backtester reported the strategy showed positive returns on paper, though practical challenges like thin liquidity and unknown resolution timing complicated real-world execution
- The bot is a fun, self-aware meme project that has successfully nerd-sniped the entire community into debating market theory
Opposed
- If 73% of markets resolve to No and No shares are priced around 73 cents, the expected value is zero — the resolution rate alone tells you nothing about profitability
- This is 'picking up pennies in front of a steamroller' — small consistent wins get wiped out by occasional catastrophic losses, similar to selling naked options
- Rational actors and arbitrageurs will quickly correct any systematic mispricing, so any edge from this strategy would be short-lived
- Prediction markets are fundamentally unregulated gambling platforms where insiders and the house always win — ordinary participants should simply not play
- The strategy ignores opportunity cost: money locked up in slow-resolving bets earns zero return versus the risk-free rate, eating into any theoretical profits
