Kalshi in the UK: The Problem
Kalshi operates under CFTC regulation as a licensed prediction market in the United States. The platform restricts access exclusively to American residents through geographical enforcement — residents of the United Kingdom face account creation barriers and cannot participate. For those seeking a functionally equivalent platform accessible within UK jurisdiction, PolyGram provides comparable market depth alongside broader geographic availability.
