How a free arbitrage calculator mindset works on Kalshi

A free approach to arbitrage on Kalshi starts with the basic invariant: the best YES ask price plus the best NO ask price should equal $1.00 in a fair market. When that sum dips below $1.00, you can consider buying both legs to lock in the spread. This section covers the mechanics of that edge, including how to read the order book, what a meaningful spread looks like in cents, and how fees affect the guaranteed portion of the profit. Keep in mind that Kalshi is a CFTC-regulated US market with USD settlement, so any calculator-based method must respect settlement rules and per-contract fees.

From free concept to real-world workflow

In practice, a free-or-low-cost arb workflow starts with scanning for markets where bestAsk(YES) + bestAsk(NO) < $1.00. If you see a 0.60/0.38 or similar combination, your gross edge is around 0.02–0.04, before fees. The next step is to verify that the markets are open, ensure there are no position limits blocking your size, and confirm that the settlement rule is straightforward. This section walks through a sample setup, including how to size a two-leg play, how to account for Kalshi’s fee curve, and how to avoid self-trade scenarios in a high-speed environment.

FAQ

What exactly is an arbitrage opportunity on Kalshi right now?
An arbitrage opportunity exists when the best YES price plus the best NO price is below $1.00, allowing you to buy both sides and lock in a risk-defined edge after fees.
Is there a truly free arbitrage calculator for Kalshi?
You can conceptually work through edge calculations without a paid tool, but real-time, reliable automation for alerts and execution typically requires a paid tool or service that integrates with Kalshi APIs.
Do YES + NO alerts mean guaranteed profit?
No. Edges depend on spreads, fees, settlement timing, and market dynamics. The edge is defined as the guaranteed cents after costs, not a guaranteed dollar amount.
How does KalshiArb help with timing and execution?
KalshiArb provides non-custodial alerts and automation that streamlines detection of favorable spreads and helps you act quickly within Kalshi’s rules and fee structure.
Are there risks to relying on arbitrage alerts?
