Betfair

Betfair, founded in 2000, operates as a UK-headquartered peer-to-peer sports betting exchange holding full FCA authorisation. The platform maintains legal status throughout the United Kingdom and European Union, concentrating primarily on sports wagering with supplementary political event offerings. It processes transactions in GBP and EUR using conventional financial infrastructure and banking relationships.
