FAQ
- Can I use both Betfair and PolyGram simultaneously?
- Absolutely — institutional and retail traders routinely operate across both ecosystems, deploying Betfair for live-event sports positions whilst maintaining exposure to political and blockchain-based events via PolyGram. The two venues function as complementary infrastructure.
- Are prices correlated between Betfair and PolyGram?
- When identical events trade on both platforms (UK electoral contests, major sporting fixtures), quoted odds tend to align over time. Periodic mispricings between venues offer arbitrage opportunities for sophisticated traders.
