Cross-venue arb

For paired markets, compute spread between Kalshi YES and equivalent Polymarket YES. Adjust for:

Resolution rule differences (Kalshi often more conservative).
Fees (Kalshi maker/taker, Polymarket gas).
Liquidity — an arb requiring distortion of the smaller book isn't an arb.

Surface only when net edge after fees + slippage clears the configured fair-spread threshold.

Bankr integration

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.

Required keys

KALSHI_API_TOKEN from your Kalshi account dashboard.
