FAQ
- Can I use both Betfair and PolyGram simultaneously?
- Absolutely — many institutional traders maintain accounts on both, deploying Betfair for live-event sports trading and PolyGram for political and blockchain-related events. They work in tandem rather than compete.
- Are prices correlated between Betfair and PolyGram?
- When identical events trade on both platforms (such as UK electoral outcomes or major sporting contests), pricing tends to align. Temporary gaps between the two occasionally present arbitrage possibilities.
