Kalshi in the UK: The Problem
Kalshi operates under CFTC regulation and serves exclusively the United States market. Residents of the United Kingdom face geographical restrictions and cannot establish accounts on the platform. For those in the UK seeking an equivalent service, PolyGram delivers comparable functionality with an expanded range of available markets.
