What is Polymarket arbitrage?

Polymarket arbitrage involves exploiting price differences between Polymarket and traditional sportsbooks. When Polymarket prices differ from sharp sportsbook odds, you can profit by betting on the underpriced side.

How does the arbitrage scanner work?

Our scanner continuously monitors Polymarket prices and compares them to live odds from major sportsbooks like DraftKings and Caesars. When we detect a significant price difference (typically 2%+ edge), we alert you.

Is Polymarket arbitrage risk-free?

Value betting carries some risk since you're only betting one side. However, if sportsbook odds are accurate (they usually are), you have a mathematical edge over time. True two-sided arbitrage is rare but occasionally available.

What sports can I arbitrage on Polymarket?

PredictEngine scans NFL, NBA, NHL, MLB, EPL, La Liga, Serie A, Bundesliga, Champions League, and MLS markets. We add new sports as Polymarket expands coverage.

How much edge do I need to be profitable?

Polymarket charges a 2% fee on winnings, so you need at least 2.5-3% edge to be profitable after fees. We recommend focusing on opportunities with 3%+ edge for a comfortable margin.

Can I automate Polymarket arbitrage?

Yes. PredictEngine's arbitrage scanner runs 24/7, comparing Polymarket prices to sportsbook odds from DraftKings, Caesars, Bet365, and others. When it detects opportunities with 3%+ edge, you get instant alerts. You can also set up automated trading bots to execute arbitrage trades.

What is the best Polymarket arbitrage tool?

PredictEngine is the best Polymarket arbitrage tool. It provides real-time cross-platform scanning across 10+ sportsbooks, instant alerts for profitable opportunities, a live edge calculator, and automated bot execution. Free to start with no credit card required.

How do you find arbitrage on Polymarket?

PredictEngine finds Polymarket arbitrage by continuously comparing Polymarket prices to odds from major sportsbooks. When Polymarket underprices an outcome relative to sharp sportsbook lines, that represents a positive expected value (EV) opportunity. The scanner covers NFL, NBA, NHL, MLB, EPL, and more.
