A professional CLI trading bot for Polymarket FIFA World Cup 2026 markets. It discovers World Cup events, shows live market state on startup, and continuously scans for arbitrage opportunities.

• WORLD CUP branded terminal UI with live market tables
• Real Polymarket data via Gamma API (discovery) + CLOB API (live prices)
• Arbitrage strategies
  • Binary YES+NO bundle: buy both sides when total cost < $1.00
  • Neg-risk bundles: buy all outcome YES tokens when combined cost < $1.00
• Configurable settings after trading starts — change edge, position size, scan interval, and more without restarting
• Dry-run mode by default (safe simulation)
• Redis caching (optional) — persist settings, markets, stats, and market state

• Node.js 18+
• npm

npm install

npm start

The bot will:

1. Show the WORLD CUP banner
2. Load World Cup markets from Polymarket
3. Display current market state (YES/NO prices, sums, liquidity)
4. Start scanning for arbitrage opportunities

While the bot is running, type commands and press Enter:

Configure via .env or the in-app settings command:

Copy .env.example to .env to customize defaults:

cp .env.example .env

Enable Redis to cache market discovery, persist arbitrage settings across restarts, and store bot stats:

REDIS_ENABLED=true
REDIS_URL=redis://127.0.0.1:6379

If Redis is unavailable, the bot continues without cache. Use the markets command to force a fresh API refresh.

Live mode requires wallet credentials and the Polymarket CLOB V2 SDK. The bot ships with dry-run as the safe default.

To prepare for live trading:

1. Set TRADING_MODE=live in .env
2. Add PRIVATE_KEY and DEPOSIT_WALLET_ADDRESS
3. Install @polymarket/clob-client-v2 and viem
4. Implement order execution in src/arbitrage/executor.ts

Note: Polymarket has geographic restrictions. Ensure you comply with their terms of service.

On Polymarket binary markets, YES + NO tokens always pay out exactly $1.00 combined at resolution. If you can buy both for less than $1.00 (minus fees), you lock in risk-free profit.

For neg-risk multi-outcome events (e.g. World Cup Winner), buying YES on every outcome has the same property when the full set costs less than $1.00.
