FAQ
- Can I arbitrage between Betfair and prediction markets?
- Pricing gaps do surface from time to time when identical events trade across both venues. Slippage from currency swaps and execution lag make true arbitrage challenging, though comparative analysis remains a useful edge-building tool.
- Is PolyGram a Betfair alternative?
- Within sports betting, it qualifies — given its multi-category reach and absence of access restrictions. For rapid in-play sports trading, Betfair's infrastructure remains the more mature option.
