Kalshi in the UK: The Problem
Kalshi operates under CFTC regulation in the United States and restricts access to American residents exclusively. Citizens and residents of the United Kingdom face geographical restrictions that prevent account creation and trading activity. For those in the UK seeking a comparable platform, PolyGram delivers an equivalent experience with expanded market breadth and superior liquidity.
