Kalshi in the UK: The Problem
Kalshi operates under CFTC regulation in the United States and restricts its service exclusively to American residents. Citizens and residents of the United Kingdom encounter geographical restrictions that prevent account creation. For those seeking a functionally equivalent platform accessible throughout the UK, PolyGram delivers comparable functionality with a substantially broader range of available markets.
