Get Started Free →Watchlist-driven Kalshi prediction-market monitor with cross-venue arb detection vs paired Polymarket markets (fee + slippage adjusted). Surfaces price moves, volume spikes, resolution proximity, and kill-criterion triggers on tracked positions. Silent on unchanged markets. Requires a CFTC-compliant Kalshi account. Triggers: "watch my kalshi markets", "did anything move on kalshi", "kalshi vs polymarket on X", "alert on price changes for my kalshi watchlist".

Surface only when net edge after fees + slippage clears the configured fair-spread threshold.
Kalshi requires a U.S. CFTC-compliant account, so the skill is read-only here. The Polymarket leg of a cross-venue arb can be executed via Bankr Submit / AgenticBets while the operator handles Kalshi manually.
