How this service works
Prediction market cross-venue arbitrage — matches live Polymarket contracts to Kalshi contracts for the same events: both leg strategies, gross cost, Kalshi taker fee, net edge per contract, ARB_CANDIDATE / CONVERGENCE_GAP / ALIGNED verdicts. Optional ?query= topic filter. Deterministic order-book math, no LLM.
Output
A list of matched Polymarket/Kalshi contract pairs for the same event, each with the both-leg trade strategy, gross cost, Kalshi taker fee, net edge per contract, and a verdict of ARB_CANDIDATE, CONVERGENCE_GAP, or ALIGNED. Computed using deterministic order-book math with no LLM involvement.
Example use cases
Real-time surebet detection for political events
“Check Polymarket and Kalshi for any profitable both-leg trades on the 2024 election outcome contracts — I want to see which pairs have a positive net edge after all fees, and flag anything that's an ARB_CANDIDATE so I can act fast.”
Cross-venue convergence monitoring during market moves
“Watch the Fed rate decision contracts across Polymarket and Kalshi and tell me when the spread widens enough to create a CONVERGENCE_GAP — I need the net edge and gross cost upfront so I know if it's worth the capital.”
Systematic arb scanning across all live event contracts
“Scan both markets right now for every event contract pair where there's a mismatch — show me all the ARB_CANDIDATE and CONVERGENCE_GAP verdicts with the two-leg strategy and net profit after Kalshi taker fees so I can rank them by edge.”
