Discover how to profit from price discrepancies between prediction markets like Kalshi and Polymarket. Learn to identify opportunities, calculate real profit after fees, and mitigate execution risks.
Arbitrage: Free Money (Maybe!)
Prediction markets offer unique arbitrage opportunities. Prices on platforms like Kalshi and Polymarket, while theoretically reflecting probabilities, sometimes diverge. This is where you come in! Oddspool.com is a great tool to spot these juicy discrepancies.
Finding the Edge: Kalshi vs. Polymarket
Imagine Kalshi prices 'Elon to Mars' at 10% while Polymarket has it at 15%. Oddspool.com shows you this. Buy on Kalshi, sell on Polymarket! But wait...
Fees & Slippage: The Profit Eaters
Fees are the silent killer. Both platforms charge fees. Calculate net profit. Let's say buying 'Mars' on Kalshi costs $0.10 (10%) + $0.01 fee, and selling on Polymarket nets $0.15 (15%) - $0.01 fee. Real profit: $0.03. Slippage (price changing during execution) can further erode gains. Always factor this in!

Execution is Key: Speed and Strategy
Arbitrage windows close fast. Use market orders cautiously; limit orders are often better to control price. Consider the 'Pope' market (7%?!) – news breaks fast! Also, watch platform rules; Kalshi and Polymarket have different contract structures.
Risk Management: Don't Be Greedy
Diversify! Don't put all your eggs in one 'Supervolcano' (19%!) basket. Start small, learn the ropes, and gradually increase your stake. Arbitrage is about consistent small wins, not overnight riches. Remember, even 'sure things' can go south. Good luck, and may the odds (and Oddspool) be ever in your favor!
