What Is Polymarket?
Polymarket is the world’s largest prediction market by trading volume, processing over $44 billion in volume during 2025 alone. Built on the Polygon blockchain, it lets users trade on the outcomes of real-world events using USDC (a US dollar stablecoin).
Polymarket gained massive attention during the 2024 US presidential election, where it became more accurate than traditional polls and was cited by major media outlets.
How Polymarket Works
- Connect wallet — Use MetaMask, Coinbase Wallet, or create an account with email
- Deposit USDC — Fund via crypto transfer or credit card (MoonPay)
- Browse markets — Thousands of active markets across all categories
- Buy shares — YES or NO shares that pay $1 if correct
- Trade freely — Full order book with limit and market orders
- Settlement — Resolved by UMA’s optimistic oracle system
Available Markets
Polymarket has the broadest market selection of any prediction platform:
- Politics — US and global elections, policy, geopolitics
- Crypto — Bitcoin price, ETF approvals, protocol upgrades
- Sports — Major leagues, tournaments, player props
- AI/Tech — Product launches, company milestones, AI benchmarks
- Culture — Celebrity events, viral moments, entertainment
- Economics — Rate decisions, inflation, economic indicators
The US Access Question
Polymarket is not available to US residents per its terms of service. The platform was fined $1.4M by the CFTC in 2022 and subsequently blocked US access.
However, many US users access Polymarket via VPN services. This is a legal gray area — while Polymarket blocks US IPs, using a VPN to access the platform may violate their ToS and potentially US regulations.
If you’re in the US and want a legal option, consider Kalshi instead.
Fees and Costs
- Trading fees: None (cost is in the spread)
- Deposit fees: Gas fees for crypto transfers, ~2.9% for credit card via MoonPay
- Withdrawal fees: Minimal gas fees on Polygon
- No account fees
Who Should Use Polymarket?
Polymarket is ideal if you:
- Are comfortable with cryptocurrency and wallets
- Are outside the US (or understand the VPN implications)
- Want the deepest liquidity and tightest spreads
- Want access to the widest variety of markets
- Don’t need regulatory protection
