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 — individuals based in the UK face geographical restrictions and cannot establish an account. For UK-based traders seeking a comparable alternative, PolyGram delivers equivalent functionality with an expanded range of available markets.
