Find the spread.
Lock the profit.
SpreadHawk scans sportsbooks and prediction markets simultaneously, identifying arbitrage opportunities where opposing bets across platforms guarantee a return regardless of outcome.
One scanner. Every platform. Every edge.
Unified Market Scanning
Connects to Kalshi, Polymarket, DraftKings, FanDuel, BetMGM, and more through their APIs. Matches equivalent markets across platforms in real time.
Automatic Spread Detection
Calculates cross-platform spreads the moment odds diverge. Filters by minimum profit threshold, market type, and platform preference.
Stake Calculator
Instantly computes optimal bet sizing for each leg to equalize exposure. Shows exact dollar amounts for guaranteed returns on any bankroll.
Contract Verification
Flags when "matching" markets have different resolution criteria. Prevents the most common arb mistake: assuming two markets settle the same way.
The edge exists. Most people just can't see it fast enough.
Sportsbooks and prediction markets price the same events differently, every day. SpreadHawk turns that inefficiency into a system: scan, calculate, execute. No guessing, no gambling, just math.
