How a 3 bet arbitrage calculator works on Kalshi

A 3 bet arbitrage calculator examines the YES and NO sides of a binary contract and the pair's combined fair value. When the best ASK for YES plus the best ASK for NO is below $1.00, the calculator highlights an edge by suggesting you buy both sides. The resulting payoff is locked in as soon as you own both legs, minus Kalshi’s per-contract fee. This is the core of intra-market arb on Kalshi: a defined risk with a known payoff if the event resolves as you predicted.

Practical use cases and setups

In practice, traders can apply the calculator to single binary markets or to mutliples under the same event ticker where child YES prices sum to less than $1.00. The KalshiArb toolkit feeds you live price deltas and can generate alerts when the edge becomes actionable. A typical workflow involves placing paired limit orders to buy YES and NO when the edge is detected, then monitoring for fills and handling slippage and partial fills within Kalshi’s CLOB.

Fees, limits, and risk considerations

Edge doesn’t mean guaranteed profit after fees. Kalshi charges a per-contract fee that reduces the net edge, and spreads can tighten during high-volume events. Position limits and market rules may affect the ability to simultaneously hold both sides on every contract. Always factor in the final payout of $1.00 and the potential for resolution disputes or settlement timing when planning a strategy.

FAQ

What exactly is a 3 bet arbitrage calculator in Kalshi terms?
It’s a tool that assesses the combined prices of YES and NO on a single binary market to identify when the sum is less than $1.00, signaling a risk-defined edge. The calculator helps you plan how to buy both sides to lock a profit once the market settles.
Do I need to be a KalshiArb customer to use this calculator?
The concept is universal, but KalshiArb provides an implemented workflow with alerts and latency-optimized data. You can replicate the logic with Kalshi’s REST API data, but KalshiArb packages it as a non-custodial scanner + AI agent.
Are there risks that can erase the edge after fees?
Yes. Fees, slippage, partial fills, and settlement timing can erode the gross edge. Edge is defined pre-fee; after fees and any market frictions, the net profit may be smaller or not realized.
How does this interact with Kalshi’s settlement rules?
Settlement is determined by Kalshi’s written resolution rule and data sources, not by oracles. The calculator’s edge is about entering the position when prices imply a profitable setup under those rules.
