Polymarket Overview
Polymarket is the world's largest prediction market by trading volume, founded in 2020 by Shayne Coplan in New York City. The platform operates on the Polygon blockchain, with all positions denominated and settled in USDC stablecoin.
After a $1.4 million CFTC fine in 2022 and a three-year ban on US users, Polymarket spent its exile becoming a global powerhouse — processing over $3 billion in monthly trades by October 2025 and attracting $2 billion in investment from the Intercontinental Exchange, owner of the New York Stock Exchange.
In July 2025, Polymarket acquired QCEX for $112 million, purchasing the CFTC regulatory infrastructure needed to re-enter the US market legally. The US beta launched in December 2025. As of May 2026, Polymarket is valued at approximately $20 billion and processes over $15 billion in combined monthly volume.

Polymarket US Legal Status
Important: There are two separate Polymarket products. The global Polymarket (polymarket.com) is NOT available to US users. Polymarket US is a separate CFTC-regulated product available via the iOS app to eligible US residents only.
Polymarket's US re-entry followed a carefully executed regulatory strategy. In July 2025, it acquired QCEX — a CFTC-registered Designated Contract Market and Derivatives Clearing Organization — giving it the same type of federal infrastructure that Kalshi has held since 2020.
The CFTC issued an Amended Order of Designation for QCEX on November 25, 2025, and Polymarket began rolling out US access in December 2025. The rollout is phased via waitlist, with hundreds of thousands of users still awaiting access as of May 2026.
In March 2026, Polymarket signed a landmark deal with MLB as its Official Prediction Market Exchange Partner, including official data rights via Sportradar — a significant sign of institutional legitimacy.
How Polymarket Works
Polymarket uses an automated market maker (AMM) model built on the Polygon blockchain. Users trade Yes and No shares, each priced between $0.01 and $0.99 USDC. A share representing the correct outcome pays $1.00 USDC at resolution; the incorrect outcome pays $0.00.
All settlement occurs via smart contracts, meaning payouts are instant and automatic — there is no human counterparty or central clearinghouse holding your funds. This is why Polymarket can offer instant withdrawals while traditional platforms take days.
For Polymarket US users, the mobile interface is designed to abstract the blockchain complexity. You deposit USDC and trade as on any other platform, with the on-chain mechanics running in the background invisibly.
Markets Available on Polymarket
Polymarket offers a more globally diverse market mix than any US competitor. As of May 2026, the platform hosts over 3,000 active markets:
- Sports: NFL, NBA, MLB (official partner), soccer, international sports
- Politics: US elections, 2026 midterms, global elections, geopolitical events
- Crypto: Bitcoin, Ethereum, Solana, and altcoin price predictions
- Economics: Fed decisions, inflation, GDP, employment data
- Geopolitics: International relations, conflict outcomes, trade policy
- Science & Tech: AI benchmarks, scientific discoveries, space events
Note: The Polymarket US beta app currently prioritises sports markets. Political, economic and other categories are expected to expand throughout 2026 as the CFTC framework develops for US users.
Polymarket Fees Breakdown
Polymarket's fee structure is its single biggest competitive advantage over every US competitor:
- Trading fee: 0% on most markets — revenue comes from the spread
- Network gas fee: Polygon network fees — typically under $0.01 per trade
- Deposit fee: None on Polymarket (USDC conversion on your exchange varies)
- Withdrawal fee: None — instant USDC to your wallet
Compared to Kalshi's 0-7% per trade fee, Polymarket is dramatically cheaper for active traders. The only cost is the spread between the buy and sell price on each market, which is tightest on the highest-volume markets like major sports and elections.
The USDC requirement does add a one-time conversion cost (typically 0-1% on major exchanges like Coinbase) but this is offset by savings on trading fees within a few trades.

Polymarket vs Kalshi — Full Comparison
Our recommendation: Start with Kalshi if you are new to prediction markets and want the simplest US experience. Add Polymarket once you are comfortable, to access lower fees and global market depth.
Expert Verdict
Polymarket is the world's most sophisticated prediction market and its US re-entry is a watershed moment for the industry. The near-zero fee model, instant settlement, and unmatched global market depth make it the clear choice for experienced traders who are comfortable with crypto.
The rating deduction reflects the USDC requirement (a real barrier for many US users), the waitlist-only access, and the iOS-only US app. These are all temporary limitations that will ease throughout 2026 as the platform scales. Polymarket is a strong buy for the medium term — the product quality is undeniable.
