FAQ
- Can I use both Betfair and PolyGram simultaneously?
- Absolutely — institutional and retail traders routinely maintain active positions across both venues. Betfair serves live-event sports; PolyGram handles longer-duration political and alternative-outcome bets. The two platforms work synergistically rather than competitively.
- Are prices correlated between Betfair and PolyGram?
- When identical events trade on both exchanges (such as UK general elections or major sporting finals), quoted odds tend to align over time. Temporary mispricings between books occasionally emerge, offering arbitrage opportunities for alert traders.
