Create an AI Agent for Automated Prediction Market Betting on Polymarket
Build an AI agent that monitors prediction markets, analyzes odds, and places strategic bets automatically based on your criteria.
What You'll Build
Your AI agent will run 24/7 to analyze prediction markets and execute betting strategies. It can:
- Monitor market odds constantly and identify favorable betting opportunities across multiple markets
- Place bets automatically when odds meet your specific criteria or strategy rules
- Research events and outcomes by browsing news, social media, and data sources to inform decisions
- Track performance and notify you about wins, losses, and portfolio changes via email or Slack
Before You Start
- An Everna account (sign up at app.everna.io)
- A Polymarket account with funded wallet
- Budget for betting (start small, $50-$100 recommended)
- Email or Slack for notifications (optional)
Risk Warning
Prediction markets involve financial risk. Only bet what you can afford to lose. Set strict spending limits and monitor your agent closely. Past performance does not guarantee future results.
How to Set It Up
Create Your Agent
Go to app.everna.io and click New Agent. Give it a name like "Polymarket Betting Bot" or "Prediction Market Trader".
Define Your Betting Strategy
Tell your agent exactly how to bet. Be specific about markets, odds thresholds, bet sizes, and risk limits. Here are three example strategies:
Strategy 1: Value Betting on Undervalued Outcomes
"Monitor all US politics markets on Polymarket every 30 minutes. Research each event by checking recent news articles and social media sentiment. When you find an outcome that seems undervalued (your analysis suggests 60% probability but market odds show 40%), place a bet of $25. Never bet more than $100 total per day. Send me a Slack notification with your reasoning before placing any bet."
Best for: Informed bettors who want AI to do research and identify value
Strategy 2: Arbitrage Opportunities
"Monitor the same events across Polymarket and other prediction markets. When you find an arbitrage opportunity where you can bet on both outcomes and guarantee a profit (accounting for fees), execute both bets immediately. Maximum bet size $50 per opportunity. Only take arbitrage with at least 3% profit margin. Track all trades in a spreadsheet and email me daily summaries."
Best for: Low risk, guaranteed small profits from price differences
Strategy 3: Event Driven Betting
"Watch for specific trigger events in technology markets. When a major tech company announces earnings, immediately check related prediction markets (stock price, product launches, executive changes). Within 5 minutes of the announcement, analyze the news and place bets on outcomes you think the market has not properly priced yet. Bet up to $75 per event. Focus on markets with high volume. Send me instant notifications for all trades."
Best for: Capitalizing on breaking news before markets adjust

Best Practices for Prediction Market Betting
Start with Small Bets
Begin with $10-25 per bet while you learn how your agent performs. Increase bet sizes gradually after you see consistent results.
Set Strict Daily Limits
Always include a maximum daily spending limit in your strategy (eg. "Never bet more than $100 per day"). This prevents runaway losses.
Require Notifications Before Betting
Have your agent send you a notification with reasoning before placing bets. This lets you cancel bad trades and learn from its decision making.
Focus on High Volume Markets
Bet on markets with lots of activity and liquidity. Low volume markets can have wide spreads and unpredictable outcomes.
Track Everything
Have your agent log every bet, reasoning, outcome, and profit/loss to a spreadsheet. Review weekly to refine your strategy.
Avoid Emotional Markets
Markets driven by hype or fear (viral events, celebrity drama) are often mispriced. Stick to markets with clear data and fundamentals.
Common Issues and Solutions
Agent is placing too many bets too quickly
Add rate limits to your strategy like "Wait at least 1 hour between bets" or "Maximum 5 bets per day". Also increase the minimum confidence threshold.
Bets are failing or timing out
Check your Polymarket wallet has enough funds and gas. Verify your agent has proper authentication. Try reducing bet sizes if markets have low liquidity.
Agent is not finding good opportunities
Your criteria might be too strict. Lower confidence thresholds slightly, expand to more market categories, or increase monitoring frequency.
Losing money consistently
Pause your agent immediately. Review all trades to identify patterns in losses. Adjust your strategy, reduce bet sizes, or focus on different types of markets. Consider paper trading first.
