Kalshi in the UK: The Problem
Kalshi operates under CFTC licensing as a US-regulated prediction market platform. Its service footprint is restricted to American residents exclusively — individuals in the UK face geographical restrictions and cannot establish accounts. For UK-based traders seeking an equivalent platform, PolyGram delivers comparable functionality alongside an expanded range of tradeable markets.
