How to Bet on Polymarket: Your First Trade in 10 Minutes (2026)

Polymarket is a prediction market: you trade shares in the outcome of real events, such as an election, a match or a rate decision, with other users rather than against a bookmaker. This guide walks through the first trade, from checking you are allowed to use it to withdrawing your money.

WhaleSays is independent and not affiliated with Polymarket. All facts about the platform are linked to Polymarket's documentation. This is education, not financial advice.

What you need: a country where Polymarket is open, about 10 minutes, a way to pay (a card, or USDC from an exchange) and money you can afford to lose.

Step 1: Check your country is supported

Polymarket restricts trading from certain locations because of sanctions and local regulation. Its geoblock documentation splits them into two groups:

• Blocked completely: sanctioned jurisdictions such as Iran, Syria, Cuba and North Korea. No new orders and no closing of positions.
• Close-only: a long list including the United Kingdom, France, Germany, Australia, Italy, Singapore and the United States on the main site. You can close positions but not open new ones.

Several more places are close-only on the website but not the API, such as Ireland, Japan, the Netherlands and South Korea.

Our availability page turns this into a country-by-country answer and is updated when the rules change.

Do not try to get round a block. Using a VPN to get around a block breaks Polymarket's terms. If your country is restricted, stop here.

Step 2: Create an account

On Polymarket's site, choose to sign up. Polymarket's docs describe accounts created with an email or Google login, or by connecting an external wallet such as MetaMask or Rabby. Pick the option you are comfortable securing.

Two warnings from Polymarket 101:

• Polymarket is non-custodial, so your funds are secured by your private key. Never share it with anyone.
• If you lose access, recovery may be possible through the official recovery tool for some account types. Do not rely on it.

Only sign up on the real polymarket.com address, and be wary of messages offering to "help" with your account.

Step 3: Deposit funds

Polymarket trades in pUSD, a token backed by USDC on the Polygon network. In practice you deposit USDC or another supported asset, and it is converted for you (pUSD docs).

How much? A $20 first deposit is a sensible minimum. It sits well above the network minimums, which Polymarket lists as $2 on most chains, $7 on Ethereum and $9 on Bitcoin or Tron. It is also a first-deposit threshold that some promotions and referral programs use. Start small whatever you choose.

There are two common ways to fund an account:

Method	How it works	Watch for
Card, through a provider such as MoonPay	You buy USDC with a card inside the deposit flow	The provider sets its own fees and limits
USDC from an exchange	You send USDC from Coinbase or another exchange to your Polymarket deposit address	Use the right network, and send only supported assets

Polymarket does not charge to deposit, but intermediaries such as Coinbase and MoonPay may (fees page).

If you send from an exchange, copy the deposit address shown in Polymarket for the right network and send a small test amount first. The deposit docs warn that sending unsupported tokens "may cause irrecoverable loss." If you pick the wrong token, there is an official recovery tool.

Step 4: Find a market

Each Polymarket event is a question, and each market inside it is a Yes or No condition (markets and events). Browse by category, search for a topic, or start from what others are trading:

• Our events page lists the biggest events with live odds.
• The whale feed shows $10,000+ trades as they happen, and our whale guide explains how to read them.

Before you buy anything, open the market and read the resolution rules. Polymarket's docs say: "the market title describes the question, but the rules define how it resolves." Check the end date, the source of truth and any edge cases.

Look also at the order book. A narrow gap between the best buy and sell prices (the spread) means a liquid market. A wide gap means you pay more to get in and out.

Step 5: Buy Yes or No shares

A share costs between $0.00 and $1.00. That price is the market's implied probability, and the winning side pays $1 per share (prices and order book).

A worked example

Yes is trading at 40¢ and you spend $20.

• You get $20 ÷ $0.40 = 50 shares.
• If Yes wins, they pay 50 × $1 = $50. Profit: $30, before fees.
• If No wins, they are worth $0. You lose the $20.

Buy No if you think the chance is lower than the market says. Our odds guide shows how to convert prices to probabilities and decimal odds.

Market order or limit order?

	Market order	Limit order
What it does	Fills immediately at the best available price	Fills only at your price or better
Speed	Instant	May wait, or not fill at all
Price control	You pay the spread	You name the price
Fee	Taker fee	No fee while it rests (maker)

A limit order that fills the moment you place it is still a taker trade and pays the fee. Both order types are described in Polymarket's order docs. Orders can partially fill, and you can cancel unfilled ones at any time. Markets also have a minimum order size and price step.

For a first trade, a limit order a cent or two better than the market is a good way to learn. A market order is simpler when speed matters more than price.

You can sell before the event ends to lock in a gain or limit a loss. When a market resolves, winning shares are redeemable for $1 each and losing shares are worth $0 (resolution). An undisputed resolution usually takes about two hours after a proposal. A disputed one takes longer: if it goes to a vote, there is a 24 to 48 hour debate period and then a vote of about 48 hours.

Step 6: Understand the fees

Polymarket charges a fee to takers (orders that fill immediately) on most markets, and none to makers. The formula, from the fees page, is:

fee = C × feeRate × p × (1 − p)

where C is the number of shares and p is the price.

Category	Taker fee rate
Crypto	0.07
Sports, Economics, Culture, Weather, Other	0.05
Politics, Finance, Mentions, Tech	0.04
Geopolitics	0 (fee-free)

On our 50 shares at 40¢ in a politics market, the fee is 50 × 0.04 × 0.40 × 0.60 = $0.48. At 50¢ the fee peaks, and near 0¢ or $1 it shrinks toward zero. Our fees guide has worked examples at 50¢ and 90¢, plus the rebate tiers for frequent traders.

Step 7: Withdraw your money

When you are done, withdraw from your Polymarket balance:

1. Sell your shares, or wait for the market to resolve.
2. Choose the destination network and token, such as USDC to your exchange.
3. Confirm the receiving address carefully. Each withdrawal address is set for a specific destination.
4. Send a small test amount first if it is your first time.

Polymarket's withdrawal docs explain that pUSD is unwrapped to USDC and swapped on the way out, and that the interface enforces less than 10 basis points (0.1%) of difference in the output amount. Some exchanges no longer accept pUSD directly, so withdraw as USDC unless you know yours does.

Polymarket charges no fee to withdraw USDC, though your exchange and the network may have their own costs.

Step 8: Know the risks before you start

• You can lose everything you stake. A 90% price still fails one time in ten.
• Prices are opinions. They show what traders will pay, not what will happen.
• Resolution can be disputed. Edge cases are decided by the rules, and disputes can take days.
• Thin markets cost more. Wide spreads and large orders can move the price against you.
• You hold your own keys. Lose them and you may lose access.
• Rules change. Fees, rebates and country lists can change without notice.
• Tax and law are local. Check what applies to you and keep records of your trades.

Set a budget before you begin, and treat it as spent. If trading stops being fun, stop.

When you are ready, open your account and make that first small trade. After that, follow where big traders put their money and learn more in our guides.
