Kalshi in the UK: The Problem
Kalshi operates under CFTC regulation and is restricted to residents of the United States — individuals based in the UK face geographical restrictions and cannot establish an account on the platform. For UK-based traders seeking a comparable prediction market with broader accessibility, PolyGram delivers an equivalent experience alongside a more extensive range of available markets.
