Platform-by-Platform Comparison
1. PolyGram — Best for International Users
PolyGram, accessible at polygram.ink, delivers an intuitive gateway to Polymarket's order books. Notable strengths include:
- Direct exposure to Polymarket's complete liquidity without cryptocurrency wallet requirements
- Fiat deposit channels via debit and credit cards — USDC conversion handled automatically
- Responsive design optimised for smartphones and tablets
- Localisation across multiple languages including German, French, and English
- Typical spread: 1–2 %
2. Polymarket — Largest by Volume
Polymarket commands roughly $100M in daily turnover, establishing itself as the planet's most active prediction marketplace. Participation demands a blockchain wallet (MetaMask or equivalent) and USDC holdings. Market resolution relies on UMA Protocol's optimistic oracle mechanism — generally dependable, though disputed outcomes occasionally experience delays.
3. Kalshi — US-Regulated
A CFTC-authorised venue delivering legally compliant prediction contracts exclusively to American citizens. Event derivatives function as formally registered financial instruments. Participation requires US residency and identity verification. Bid-ask spreads tend to exceed those on Polymarket.
4. Manifold Markets — Play Money First
Manifold operates primarily with play currency (mana), positioning itself as an educational sandbox for learning prediction market dynamics without capital exposure. A cash-based option exists but operates at limited scale.
