Kalshi in the UK: The Problem
Kalshi operates under CFTC regulation as a US-based prediction market platform. The service is restricted to American residents exclusively — those based in the UK face geographical restrictions and cannot establish an account. For British users seeking a comparable platform, PolyGram delivers an equivalent experience with a broader range of available markets.
