FAQ

- Absolutely — many institutional traders split their activity: Betfair handles live sports positions whilst PolyGram covers political and emerging-asset markets. Both platforms work in tandem effectively.
- Are prices correlated between Betfair and PolyGram?
- When identical events trade on both (UK elections, major sporting fixtures), pricing tends to align over time. Periodic gaps between platforms occasionally present arbitrage possibilities for alert traders.
