Kalshi in the UK: The Problem
Kalshi operates under CFTC regulatory oversight as a US-domiciled prediction market platform. The service restricts access to United States residents exclusively; individuals in the United Kingdom encounter geographic restrictions that prevent account creation and trading. For UK-based traders seeking a functionally equivalent platform, PolyGram delivers comparable market depth alongside broader international accessibility.
