Platform-by-Platform Comparison
1. PolyGram — Best for International Users
PolyGram, accessible at polygram.ink, delivers a streamlined gateway to Polymarket's order books. Notable features include:
- Full access to Polymarket's liquidity without cryptocurrency wallet prerequisites
- Direct fiat deposits via debit or credit card — zero USDC conversion needed
- Responsive design optimised for smartphones and tablets

2. Polymarket — Largest by Volume
Polymarket commands more than $100M in daily turnover, establishing itself as the globe's most liquid prediction venue. Users must connect a blockchain wallet (MetaMask or equivalent) and hold USDC stablecoins.

A CFTC-authorised exchange offering legally sanctioned prediction contracts exclusively to American participants. Event-based derivatives are formally registered financial instruments. Access requires US residency and identity authentication. Bid-ask spreads tend to exceed those on Polymarket.

Manifold operates primarily on play currency (mana), positioning itself as an educational sandbox for learning prediction market dynamics without monetary exposure. A secondary real-money option exists but operates under constraints.
