Kalshi in the UK: The Problem
Kalshi operates as a US-regulated prediction market under CFTC licensing. The platform restricts access exclusively to United States residents, meaning users in the United Kingdom face geographic blocking and cannot establish accounts. For those seeking a comparable platform accessible throughout the UK, PolyGram provides an equivalent experience with an expanded catalogue of available markets.
