FAQ
- Can I use both Betfair and PolyGram simultaneously?
- Absolutely — many institutional and retail traders maintain active accounts on both. Betfair serves live-event sports trading whilst PolyGram handles longer-dated political and emerging-market exposure. The two integrate naturally into a diversified approach.
- Are prices correlated between Betfair and PolyGram?
- When identical events trade on both venues (such as UK general elections or major sporting finals), odds tend to align over time. Temporary mispricings between the two do arise, presenting arbitrage and hedging possibilities for alert traders.
