Where Betfair Wins
- Live sports trading: Betfair's real-time markets during competition deliver unparalleled depth — prices shift moment-to-moment as play unfolds
- Horse racing: Betfair's thoroughbred racing liquidity far exceeds what any prediction market platform can match
- UK/EU sporting events: Major tournaments like the Premier League, Six Nations, and Wimbledon tend to see superior depth on Betfair versus prediction markets
- Traditional currency: Traders working in GBP or EUR avoid cryptocurrency mechanics entirely
Where PolyGram Wins
- Political outcome markets: US presidential contests, international political outcomes — substantially more liquidity on Polymarket's central limit order book
- Blockchain and scientific events: Betfair simply does not support these categories
- Unrestricted accounts: profitable traders face no throttling or closure risk
- Worldwide participation without regional restrictions
- USDC payouts — settlements occur on-chain without banking intermediaries
FAQ
- Can I use both Betfair and PolyGram simultaneously?
- Absolutely — many institutional traders deploy Betfair for live sports action and PolyGram for political and blockchain-based events. The two platforms work in tandem rather than compete.
- Are prices correlated between Betfair and PolyGram?
- When identical events trade on both (such as UK electoral contests or major sporting fixtures), odds generally align over time. Periodic mispricings across platforms present arbitrage opportunities for alert traders.
