How the arbitrage calculator here reveals edge in binary markets

The arbitrage calculator here is designed to compare the best YES and NO prices on a single Kalshi binary market. When the sum of the best ask prices is under $1.00, buying both legs guarantees a small, risk-defined edge. The calculator translates those prices into a per-contract profit range after accounting for Kalshi’s fee curve. You’ll see the edge compress as prices approach 50 cents, and widen when one side trades far from parity. In practice, this means you can buy YES at 0.40 and NO at 0.55, with a guaranteed minimum upside once settlement occurs, minus fees.

Interpreting YES and NO prices under $1.00 with the calculator

Kalshi markets are designed so that YES and NO sides are complementary and sum to about $1.00 at fair value. The arbitrage calculator here highlights when that balance is off, showing the guaranteed profit from a simultaneous buy of both sides. Since each contract settles to $1.00 for the winning side, the calculator helps you quantify potential returns and visualize the impact of the per-contract fee, which varies with price.

Using the calculator to plan an intra-market spread

For intra-market arb, use the calculator here to compare the two legs of a binary market and confirm the edge before placing orders. The tool helps you avoid slippage by using the best available prices and factoring in liquidity. You can also apply the same logic to across-child markets under a single event_ticker, where the sum of child YES prices falls short of a full $1.00, enabling a combinatorial arb.

FAQ

What exactly does the arbitrage calculator here measure?
It measures the edge from buying both YES and NO when their best prices sum to less than $1.00, accounting for Kalshi’s fee curve and settlement mechanics.
Do I need to connect my Kalshi API to use the calculator here?
The calculator here can be used with public market data, but for executing trades you would use Kalshi’s API with proper authentication and signing.
Is the edge guaranteed when using the calculator here?
No. The calculator highlights a potential edge under current prices, but edge depends on liquidity, fill risk, fees, and settlement timing.
Can I apply this to combinatorial markets under one event_ticker?
Yes. The calculator can assess sums across child YES prices to see if a complete set offers a risk-defined spread.
