Why Automate Sports Betting?
Sports markets on Polymarket move fast during live games. Scores, injuries, and momentum shifts cause rapid price swings. A bot reacts in milliseconds while manual traders miss opportunities.
Cross-platform odds comparison is the killer feature. Bots scan DraftKings, FanDuel, Pinnacle, and Polymarket simultaneously, finding value bets that would take manual traders hours to discover.
Setting Up Your Sports Bot
In PredictEngine, create a bot and select sports markets. Choose your sport (NFL, NBA, soccer, etc.) and configure: minimum value edge (e.g., 5% vs sportsbooks), position size per game, and maximum daily exposure.
The bot integrates with PredictEngine's sports arbitrage scanner, which compares odds across platforms in real-time and identifies value opportunities automatically.
Live Game Trading
Sports bots can trade during live games. Set pre-game targets and the bot executes when prices reach your levels during gameplay. This captures in-game value created by scoring events.
Example: Pre-set a buy on Lakers YES if price drops below $0.35 during the game. When the opposing team takes a lead and Lakers YES dips, your bot buys automatically before the price recovers.
Sports Bot Strategies
Value betting: buy when Polymarket implies worse odds than sportsbooks. Arbitrage: take opposite positions on Polymarket and a sportsbook for risk-free profit. Closing line value: trade based on where the line is moving.
PredictEngine's AI can generate sports strategies from plain English. Example: "Trade NBA games where the favorite is at least 7% cheaper on Polymarket than DraftKings."
