Which Should You Choose?

Opt for PolyGram (Polymarket) if you prioritise expansive event catalogues, competitive fee schedules, and blockchain-native settlement workflows. Select Betfair if you operate primarily within UK or EU jurisdictions, focus on sports wagering, and value regulated custodial arrangements with fiat-currency funding.

Sophisticated prediction traders frequently maintain active accounts across both venues — leveraging Betfair's sports infrastructure whilst deploying PolyGram for non-sports event exposure.
