What Is Polymarket?

How Polymarket Works

Polymarket operates as a peer-to-peer exchange built on the Polygon blockchain. Instead of betting against a house, you trade shares with other users in an open order book. Every market poses a question with a binary outcome — YES or NO — and shares for each side trade between $0.01 and $1.00.

The price of a share represents the market's collective estimate of the probability. A YES share trading at $0.72 means the crowd thinks there's a 72% chance the event will happen. When the event resolves, winning shares pay $1.00 and losing shares pay $0.00.

All trades settle in USDC, a stablecoin pegged 1:1 to the US dollar. You can deposit via crypto wallet, credit card, debit card, or bank transfer through integrated payment providers.

How to Make a Prediction on Polymarket

Making a prediction on Polymarket follows a straightforward process:

1. 1. Create an account — Sign up with your email or connect a crypto wallet. Polymarket supports deposit wallets (no crypto knowledge needed) and proxy wallets for advanced users.
2. 2. Deposit funds — Add USDC to your account via credit card, bank transfer, or by sending crypto directly. Minimum deposits start at just a few dollars.
3. 3. Find a market — Browse by category (politics, sports, crypto, etc.) or search for specific topics. Each market shows the current probability, trading volume, and time until resolution.
4. 4. Buy shares — If you think an event will happen, buy YES shares. If you think it won't, buy NO shares. Enter the amount you want to invest and confirm the trade.
5. 5. Wait for resolution — When the event occurs (or doesn't), the market resolves. Winning shares automatically pay out $1.00 each. You can also sell your shares before resolution if the price moves in your favor.

Understanding Polymarket Prices and Odds

Prices on Polymarket directly represent probabilities. A share at $0.35 means a 35% implied chance. Your potential profit is the difference between your purchase price and $1.00 if you're right.

The order book shows all resting buy and sell orders. The spread (gap between the best bid and best ask) indicates how liquid the market is. Tighter spreads mean you can enter and exit positions with less cost. High-volume markets typically have spreads of 1–3 cents.

What Makes Polymarket Different

• Real money, real stakes — Unlike play-money prediction platforms, Polymarket uses real USDC. This incentivizes accurate forecasting because being wrong costs money.
• Blockchain settlement — Trades settle on Polygon, providing transparency and non-custodial ownership. Your positions are yours — no counterparty risk from the platform itself.
• Central limit order book — Unlike simple AMM-based markets, Polymarket uses a proper order book (CLOB) for efficient price discovery and tight spreads.
• Massive liquidity — As the largest prediction market by volume, Polymarket offers deep liquidity across hundreds of active markets, making it possible to trade meaningful sizes without excessive slippage.
• US-regulated — Since 2025, Polymarket operates as a CFTC-designated contract market in the United States, providing regulatory clarity for American traders.

Risks of Trading on Polymarket

Prediction market trading carries significant risk. You can lose 100% of your investment on any single market. Key risks include:

• Binary outcomes — Unlike stocks that can partially recover, a prediction market share goes to $0 if you're wrong. There's no middle ground.
• Illiquidity — Some markets have thin order books, making it difficult to exit large positions without moving the price against you.
• Resolution risk — Markets occasionally face disputes about how an event should be resolved, which can delay payouts or produce unexpected outcomes.
• Overconfidence — Research shows 85–90% of retail prediction market participants lose money over time. The market is competitive.

How to Research Before Trading

Successful prediction market trading requires more than gut feeling. Before entering a position, consider:

• Liquidity analysis — Is the order book deep enough to fill your order without excessive slippage?
• Spread assessment — How much does the bid-ask spread cost you on entry and exit?
• Wallet signals — Are large, historically-profitable wallets positioned on one side?
• Price momentum — Is the price trending or stable? Sharp moves may indicate new information.
• Time to resolution — How long until the market resolves? Longer timeframes mean more uncertainty.
