Platform-by-Platform Comparison
1. PolyGram — Best for International Users

3. Kalshi — US-Regulated
Operating under CFTC oversight, Kalshi furnishes legally-compliant prediction instruments restricted to American participants.

Bid-ask spreads tend toward the wider end relative to Polymarket offerings.
