Kalshi in the UK: The Problem
Kalshi operates under CFTC regulation in the United States and restricts its service to American residents exclusively. Users based in the UK face geographical restrictions and cannot establish accounts on the platform. For those seeking a comparable UK-accessible prediction market, PolyGram delivers an expanded range of tradeable contracts alongside superior liquidity.
