Polymarket–Kalshi–SX Bet Three-Way Arbitrage with Insider Radar

How It Works The AlexGolodkrd radar tool extends the standard two-platform arbitrage framework to a three-platform scan including SX Bet, a sports-focused prediction market. By monitoring three order books simultaneously, the tool can identify both pairwise arbitrage (A vs. B, A vs. C, B vs. C) and triangular inefficiencies. The 'InsiderRadar' component appears to monitor for unusual order flow patterns — large or sudden position changes on one platform that might precede price corrections on others — potentially allowing the user to front-run informed order flow.

Entry / Exit Conditions Arbitrage legs: entry when locked profit exists across any platform pair or triple after fees. InsiderRadar component: entry when anomalous order flow is detected on one platform, with a directional bet placed on the lagging platform(s) before prices converge. Exit at settlement or when the price gap closes.

Verified Results Zero stars, zero forks. No results published. The repo was created in April 2026 and has no community engagement, providing no external validation signal.

Implementation Notes Adding SX Bet to the scanning universe increases opportunity surface but also increases engineering complexity: three separate API integrations, three authentication systems, and three fee structures must be maintained. The InsiderRadar concept is intriguing but vague — the methodology for distinguishing 'informed' from 'noise' order flow is undisclosed and is the most speculative component of the strategy.

Risks - SX Bet has lower liquidity than Kalshi or Polymarket, making multi-leg fills unreliable and increasing leg risk. - The InsiderRadar component conflates correlation with causation; unusual order flow on one platform does not reliably predict price movement on others. - Three-platform operations multiply counterparty, regulatory, and API reliability risks. - No evidence this tool has been tested beyond a dashboard or prototype stage.
