- USDC settlement — funds arrive on-chain without banking intermediaries
FAQ
- Can I use both Betfair and PolyGram simultaneously?
- Absolutely — institutional and retail traders routinely split activity between Betfair for live-event sports and PolyGram for election forecasting and alternative asset classes. The two platforms work synergistically rather than competitively.
- Are prices correlated between Betfair and PolyGram?
- When identical events trade on both venues (UK general elections, major sporting fixtures), quoted odds tend to align over time. Periodic mispricings between platforms generate arbitrage opportunities for nimble traders.
