Polymarket Review 2026
The Global Prediction Market for US Traders
Polymarket is the world's largest prediction market by trading volume. Its US-licensed QCEX platform makes it accessible to most American traders, with the deepest liquidity on major global political and economic events. The trade-off: USDC settlement, state restrictions (NY blocked, waitlist-only), and a 2% per-trade fee that cuts into returns. This review covers everything a US trader needs to decide.
Polymarket quick numbers — 4.3/5
- Deepest liquidity on global political events
- Widest range of global markets (not just US)
- CFTC-licensed via QCEX for US traders
- Active global trader base: tight spreads on major markets
- Fiat on-ramp (no crypto wallet needed for QCEX)
- Strong app experience on iOS and Android
- 2% taker fee on every trade (including losers)
- USDC settlement: fiat conversion adds friction
- New York blocked; AZ, TN, MD restricted

Two versions of Polymarket — which one US traders use
- CFTC-licensed Designated Contract Market
- Available to US residents (excl. NY; some restrictions)
- KYC required (government ID)
- Fiat on-ramp available: no wallet needed
- USDC on Base under the hood
- ACH withdrawal to USD bank account
- On-chain on Polygon (was) / Base (current)
- Not available to US residents
- Requires crypto wallet (MetaMask, Coinbase Wallet)
- No KYC for basic access
- UMA oracle-based resolution
- Global user base including US excluded users
US residents must use QCEX. Using the original Polymarket as a US resident violates its terms of service. The QCEX product launched after Polymarket acquired the CFTC-licensed QCEX entity in December 2025.
Polymarket QCEX fee structure
Polymarket charges a ~2% taker fee on every trade: buy or sell, win or lose. This is the main fee disadvantage vs Kalshi, which only charges on winning trades.
Fee drag on active traders: If you trade in and out of positions, the 2% applies each time. A trader who enters and exits a position pays ~4% in fees (2% in + 2% out) before any profit consideration. For buy-and-hold traders who enter once and hold to resolution, the fee is paid once on entry only.
State availability for Polymarket QCEX
TX, FL, CA, GA, CO, VA, PA, OH, IL, and most others
AZ, TN, MD, MA: litigation pending
New York: fully blocked as of May 2026
QCEX is also currently invite-only (waitlist) nationally: you can sign up and wait for approval, which typically takes 1–7 days. New York residents should use Kalshi or Robinhood instead.
Common Polymarket questions
Is Polymarket legit and safe for US traders?+
Polymarket QCEX is CFTC-licensed and legal for most US residents (excluding NY). Backed by a16z, Founders Fund, and other major investors. The platform has processed billions in global trading volume. USDC on Base adds some complexity vs Kalshi's simpler USD model. See the full safety guide for details.
Do I need crypto to use Polymarket?+
For QCEX: no: the built-in fiat on-ramp lets you deposit USD via bank account or debit card and withdraw back to USD. No MetaMask or crypto wallet needed. The USDC conversion happens behind the scenes.
Is Polymarket better than Kalshi?+
For global political events (US and international elections, major geopolitical outcomes): Polymarket typically has deeper liquidity. For US domestic markets (Fed rate, economic data, weather): Kalshi is often more liquid and has simpler USD settlement. Many serious traders use both. New York residents and traders in restricted states must use Kalshi.
How do I withdraw money from Polymarket QCEX?+
QCEX Withdraw → bank account → enter amount. Polymarket converts USDC to USD and sends via ACH (3–5 business days). Alternatively withdraw USDC to a crypto wallet and convert via Coinbase.
