Platform-by-Platform Comparison
1. PolyGram — Best for International Users
PolyGram at polygram.ink offers a streamlined gateway into Polymarket's order books. Notable strengths include:
- Full connectivity to Polymarket's liquidity without owning cryptocurrency
- Credit card deposits available — USDC acquisition handled automatically
- Responsive design across tablets and smartphones
- Multilingual interface spanning German, English, and additional languages
- Typical spread: 1–2 %
2. Polymarket — Largest by Volume
Polymarket commands approximately $100M in daily turnover, establishing itself as the globe's most liquid prediction exchange. Users must connect a digital wallet (MetaMask or equivalent) and hold USDC on the Polygon blockchain. Outcomes are determined through UMA Protocol's optimistic oracle mechanism — generally dependable, though resolution may lag on disputed contracts.
3. Kalshi — US-Regulated
A CFTC-authorised venue delivering legally-sanctioned event contracts exclusively to American participants. Contracts function as formally-registered financial instruments subject to regulatory oversight. Restricted to US-based users with completed identity checks. Bid-ask spreads tend to be marginally wider than those on Polymarket.
4. Manifold Markets — Play Money First
Manifold operates primarily on fictional currency (mana), positioning itself as an educational sandbox for learning prediction market dynamics without capital exposure. A real-money component exists but operates under strict constraints.
