About KalshiArb
KalshiArb is an independent third-party arbitrage scanner and execution bot for the Kalshi event-contract exchange. We are not affiliated with KalshiEX LLC. We consume Kalshi's public REST API, compute YES + NO mispricings on every open binary market, rank multi-outcome events by the sum of their mutually-exclusive YES legs, and surface the result as live alerts plus an optional autonomous trading agent.
Why Kalshi specifically
Kalshi is the only U.S. CFTC-regulated event-contract exchange we know of with deep enough order-book liquidity to make arbitrage worth running 24/7. Contracts settle in USD at either $0 or $1, prices are quoted in integer cents from 1 to 99, and the API is public, well-documented, and stable. That combination is rare — most prediction venues are either too thin, too unregulated, or too crypto-native for retail-grade arbitrage to clear fees.
What we do
- Pull every open Kalshi event contract every five minutes and recompute YES + NO ask sums and ranks.
- Fire Telegram + Discord alerts the moment a binary market clears our minimum per-contract edge floor (or a multi-outcome event sums under $1.00).
- For paid Autonomous Agent customers, send both legs as a single batched submission through the customer's Kalshi API key, with bankroll-aware Kelly sizing and a 2% per-leg cap.
What we don't do
- Touch your funds. You keep your Kalshi balance and your API key.
- Promise returns. Past edges do not predict future edges.
- Trade in restricted jurisdictions. The agent geo-fences against Kalshi's state-by-state restrictions and refuses to submit if your IP is in a blocked state.
