FAQ
- Can I use both Betfair and PolyGram simultaneously?
- Absolutely — professional traders routinely split their capital between Betfair for live-action sports and PolyGram for political markets and emerging asset classes. The two platforms work synergistically rather than competitively.
- Are prices correlated between Betfair and PolyGram?
- When identical events trade on both venues (general elections, major sporting fixtures), odds tend to align over time. Periodic mispricings between platforms present arbitrage opportunities for alert traders.
