Reading the Arbitrage Opportunity boxes
An arbitrage opportunity appears when the same event is priced inconsistently across two venues β in theory letting you lock in a return regardless of which side resolves true.
Step by step
- Confirm the match. Check that both venues describe the same event β same wording, same resolution date, same resolution criteria. Small differences can mean the markets settle differently, which kills the arb.
- Note the sides. The box tells you which contract to buy on which venue (e.g., YES on Polymarket @ $0.46 + NO on Kalshi @ $0.49). Their combined cost should be less than $1.
- Read the spread. The headline percentage is the gross edge β before any costs.
- Subtract real costs. Trading fees, withdrawal fees, gas, and the price you'd actually fill at (top-of-book size is usually thin and the book walks once you take it).
- Check feasibility. You need pre-funded accounts on both venues β capital rarely moves fast enough between them to chase a live spread.
- Watch timing risk. If the venues resolve at different times, your capital can sit locked between settlements, and one leg may move against you in the interim.
