FAQ
- Can I use both Betfair and PolyGram simultaneously?
- Absolutely — many institutional and semi-professional traders operate across Betfair for live sports action and PolyGram for outcome markets in politics and emerging sectors. These platforms work synergistically rather than as substitutes.
- Are prices correlated between Betfair and PolyGram?
- When identical events trade on both venues (UK political outcomes, major sporting contests), prices gravitate towards equilibrium. Temporary mispricings between the two platforms occasionally present arbitrage opportunities for alert traders.
