What a polymarket kalshi arbitrage bot looks for on Kalshi

In practice, the idea is simple: scan the Kalshi order book for YES and NO contracts under the same event and detect when the best asks sum to less than $1.00. When that edge exists, you can theoretically buy both legs and lock in near-cents of risk-free profit after fees. KalshiArb surfaces these opportunities in real time, highlighting when the intra-market edge appears and how much room you have to capture value. Traders still pay Kalshi’s per-contract fee, so the real question is whether the edge after fees remains attractive across the target size.

How intra-market spreads translate into tradable edge

The core arbitrage condition is that bestAsk(YES) + bestAsk(NO) < $1.00. If you can buy both at prices well under 50–60 cents each, the combined outlay leaves a cushion. Kalshi’s price ticks are in cents, and the total potential payoff per contract is fixed at $1.00. With initial alerts, you can act quickly before volatility or slippage closes the gap. KalshiArb helps by monitoring the live book and alerting you when the sum of child prices signals a tradable edge.

Using KalshiArb as a non-custodial tool for edge hunting

KalshiArb is non-custodial: you keep your API keys, funds, and account ownership with Kalshi. Our scanner and autonomous AI agent provide signals and execution guidance, not funds transfer.
