Kalshi in the UK: The Problem
Kalshi operates under CFTC regulation as a US-based prediction market platform. Its service territory is strictly limited to American residents; individuals located 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 greater depth.
