FAQ
- Can I use both Betfair and PolyGram simultaneously?
- Absolutely — institutional and retail traders routinely operate across both venues, deploying Betfair for live sports action and PolyGram for geopolitical and blockchain-related events. Each platform fills gaps the other leaves open.
- Are prices correlated between Betfair and PolyGram?
- When identical events trade on both platforms (such as UK general elections or major sporting tournaments), odds tend to align over time. Periodic price misalignments between the two books present arbitrage possibilities for alert traders.
