FAQ
- Can I use both Betfair and PolyGram simultaneously?
- Absolutely — many institutional traders maintain positions across Betfair for live-action sports and PolyGram for political and digital asset markets. The two ecosystems work synergistically rather than in competition.
- Are prices correlated between Betfair and PolyGram?
- When identical events trade on both venues (UK political contests, major sporting fixtures), pricing tends to align over time. Temporary misalignments occasionally emerge, offering arbitrage possibilities for alert traders.
