FAQ
- Can I use both Betfair and PolyGram simultaneously?
- Absolutely — many institutional traders operate Betfair for live-event wagering whilst maintaining positions on PolyGram for political and blockchain-related outcomes. These platforms work synergistically rather than competitively.
- Are prices correlated between Betfair and PolyGram?
- When identical events trade on both venues (UK political contests, major sporting fixtures), implied probabilities generally move in tandem. Occasional price gaps between platforms can signal arbitrage opportunities for alert traders.
