Step 1
Two platforms disagree on the same event. Polymarket prices YES at 50¢. Kalshi prices NO at 40¢. Buy 100 shares of both and you've spent $90.
Polymarket
KalshiStep 2
Now, if Bitcoin is over $100K, you make $100 on Polymarket; if Bitcoin is under $100K, you make $100 on Kalshi. No matter what happens, you profit $10.
If BTC < $100K
Kalshi pays $100
If BTC > $100K
Polymarket pays $100
Step 3
Regardless of the outcome, you're up $10 on your $90 bet. We're not predicting the future - we're arbitraging the difference.
