Frequently Asked Questions
What is the current arbitrage spread for "Will Germany win Euro 2024?"?
The current gross spread is 5.0 percentage points: Kalshi prices YES at 17¢ and Polymarket prices YES at 22¢. This data updates hourly via Musashi.
How do I trade this arbitrage?
Buy YES on Kalshi at 17¢ per share. Simultaneously sell YES on Polymarket at 22¢. Your locked-in gross spread is 5.0¢ per share because you collect the higher sale price and pay the lower entry price up front. If YES resolves, the long pays $1 and the short owes $1; if NO resolves, both legs expire worthless, and in either case you keep the initial spread before fees and slippage.
Is this arbitrage risk-free?
Near risk-free in theory, but execution risk exists. Both legs must fill before the spread closes. Slippage, position limits, and the time required to withdraw funds between platforms reduce the realized profit. Model your net spread after fees and slippage before committing.
