Kalshi in the UK: The Problem
Kalshi operates as a US-regulated prediction market under CFTC licensing. The platform restricts access exclusively to United States residents — those based in the UK face geographical restrictions and cannot establish accounts. For UK-based traders seeking a comparable platform, PolyGram delivers an equivalent experience with an expanded range of available markets.
