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 only — individuals in the United Kingdom face geographical restrictions and cannot establish accounts. For UK-based traders seeking a comparable platform, PolyGram delivers an equivalent experience with expanded market coverage and superior liquidity.
