What an arbitrage calculator does for Kalshi markets

An arbitrage calculator translates the price of YES and NO contracts into potential profit when the sum is under $1.00. On Kalshi each side is priced in cents, and the calculator lets you input current bid/ask for YES and NO, then computes the guaranteed edge if you buy both legs. The key idea is the edge equals one minus the sum of the two legs, expressed in dollars. Operators often look for conditions where the combined price is below $1.00 and still profitable after the per-contract fee.

How to feed inputs and read outputs

To use the tool effectively, you input the best bid/ask for YES and NO from the market book. The calculator then outputs the maximum risk-free spread you can lock in by buying both sides, minus fees. Look for edges that persist across multiple contracts in the same event, and note how the total price approaches $1.00 as the event nears resolution. This helps you decide whether to place a hedge now or wait for a more favorable cross-side delta.

Interpreting alerts and timing for Kalshi

Alerts based on sub-$1.00 sums are most valuable when they fire in real time. The calculator helps you quantify how much you stand to gain per contract if the market moves toward parity, after Kalshi’s fee curve. In practice, you’ll use alerts to act quickly on favorable edge conditions, especially in high-volume events where spreads compress briefly. Remember that resolution timing and rule-based settlement source determine final payoff, not the calculator alone.
