Prediction Market Arbitrage

Calculate cross-venue arbitrage: gross spread, fee-adjusted net edge, capital required, and the minimum spread needed to survive fees. A 5% gross spread on Polymarket/Kalshi yields roughly 3% net after Kalshi's parabolic taker fee.

Ask your agent

Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this exact tool, with this sample, and verify the artifact.

Run the AINumbers MCP tool `find_prediction_arbitrage`. Task: Identify cross-venue arbitrage opportunities in binary prediction markets.
Call it with arguments: {"policy_parameters":{"venue_a":"polymarket","venue_b":"kalshi","yes_price_a":0.45,"no_price_b":0.5,"payout":1,"stake_total":1000}}
Verify before trusting: call `verify_execution_hash` on mcp.ainumbers.co (https://mcp.ainumbers.co/mcp) with the parameter `claimed_hash` set to the returned `execution_hash`, passing the full artifact the run returned (the object containing `policy_parameters` + `output_payload` + `execution_hash`; equivalently `policy_parameters` + `output_payload` with `claimed_hash`), not the bare hash string.
Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us.
