How to Use Polymarket: Complete Beginner's Tutorial

Using Polymarket is five moves: create an account, deposit funds that become pUSD, read a market, buy Yes or No shares priced between $0.00 and $1.00, then sell early or hold to resolution. Winning shares redeem for $1.00 and losing shares are worth $0.00, so the price you pay is at once your cost, your maximum loss per share and the market's probability estimate. Here is each step as of September 2026.

Who this guide is for, and who can trade

This covers polymarket.com, the main platform, where you trade peer-to-peer on an order book rather than against the house. New to the idea? Start with what Polymarket is. Check eligibility first: it decides which product you can use.

The help center lists 39 restricted countries, among them the United States, United Kingdom, Germany, France, Italy, Australia and Japan. Four are close-only, meaning you may exit existing positions but open no new ones: Singapore, Poland, Thailand and Taiwan. Alberta, British Columbia, Ontario and Quebec are blocked in Canada.

US residents are pointed to Polymarket US, a separate CFTC-regulated designated contract market and derivatives clearing organization. It lists event contracts only, no perpetual futures, settles at $1 or $0 in US dollars, and is not available in every state. See Polymarket US explained.

Polymarket Perps, launched broadly on September 3, 2026, does not permit order placement from the United States or Canada.

The help center strictly prohibits VPNs and similar tools for bypassing these restrictions, treating their use as a Terms of Service violation under Section 2.1.4, so do not attempt it. If your country is not named, read is Polymarket legal where you live.

Step 1: Create your account

The help center lists three sign-up routes as of September 2026.

Google: click Sign Up, select Continue with Google, connect the account.

Email: click Sign Up, enter your address, then the 6-digit code Polymarket emails you.

Crypto wallet: click Sign Up, connect MetaMask, Rabby or Phantom, then sign one message to connect and another to enable trading.

Log in the same way every time, because deposit addresses are tied to your profile.

Never share your 6-digit login code: it opens your account and funds, and Polymarket states support cannot recover funds lost that way. Outside the restricted regions you can open Polymarket, though availability depends on your jurisdiction. US readers should use Polymarket US instead; the free tools in Step 6 work either way.

Step 2: Fund the account

Polymarket trades in pUSD, an ERC-20 token on Polygon backed 1:1 by USDC. USDC or bridged USDC.e from Ethereum, Solana, Bitcoin, Tron and major layer-2 chains is wrapped into pUSD automatically. The flow: click Deposit, pick a method such as Transfer Crypto, select token and network, copy the deposit address, send at least the minimum, then refresh once it confirms.

Three traps: deposit addresses differ per blockchain and transfers to the wrong chain cannot be reversed, so test with a small amount. Each network sets its own minimum, and deposits below it stay pending until the cumulative amount clears the threshold. And Polymarket's own pages disagree on the numbers, with the developer docs listing $2 on most layer-2 chains and $9 on Bitcoin and Tron while the help center quotes different examples, so trust the deposit screen over any article, including this one.

Step 3: Read a market page before you trade

Shares trade between $0.00 and $1.00 and the price is the probability: $0.65 means roughly a 65% chance. Yes and No sum to $1.00 because $1 pUSD of collateral creates one Yes share and one No share. Browse live prices on our markets page; understanding Polymarket odds covers where that reading breaks down.

The headline number is not your fill. Polymarket displays the midpoint of the bid-ask spread, switching to the last traded price when the spread is wider than $0.10. With a best bid of $0.34 and best ask of $0.40 the page reads $0.37, but you buy at $0.40 and sell at $0.34.

Below sits the order book: bids are the highest prices buyers will pay, asks the lowest sellers will accept, the spread the gap. There are no size limits by design, but Polymarket warns there is no guarantee of transacting a desired size without moving the price, or at all without willing counterparties. Our screener filters by volume, price and anomalies so you can skip thin books.

Then read the resolution rules under the order book. Polymarket's guidance is direct: the title describes the question, the rules define how it resolves.

Step 4: Place your first order

Two ways in.

A market order fills immediately. On a buy, Polymarket walks the asks upward from the best price until your spend is used up, then treats that final price as your maximum. It never rests on the book: anything unfilled is cancelled.

A limit order names your price and waits. The help center's example: the market is at 73 cents, 72 is your maximum, so you post a bid at 72. Limit orders can partially fill, run Good Till Cancelled or Good Till Date, sit in your Portfolio's Open Orders tab, and cancel with the red x. Each market sets its own price increment and minimum order size.

The share math: 100 Yes shares at 40 cents costs $40. Resolve Yes and they redeem for $100, a $60 gain before fees. Resolve No and they are worth $0, losing the full $40.

Makers are never charged; only takers pay. The taker fee is C x feeRate x p x (1 - p), where C is shares and p is price. The rate is 0.07 for crypto, 0.05 for sports, economics, culture and weather, 0.04 for politics, finance, tech and mentions, and 0 for geopolitics. Polymarket's example: 100 crypto shares at $0.50 is a $50 trade carrying a $1.75 fee. The p x (1 - p) term makes the fee largest near 50% probability and smaller toward both extremes. Since the April 28, 2026 upgrade, fees are charged in USDC at match time and show in your trade history instead of being baked into share counts. More in Polymarket fees explained.

Step 5: Manage the position

Sell early. Any time before resolution, a market order takes the prevailing bid and a limit order executes only if a buyer appears at your price. Selling locks in a gain or caps a loss, and gives up the $1.00 you would have collected by holding and being right.

Hold to resolution. Polymarket settles through the UMA Optimistic Oracle: anyone can propose an outcome by posting a bond of typically $750 pUSD, and anyone can dispute it. A 2-hour challenge period follows. If a second proposal is also disputed, resolution escalates to UMA's Data Verification Mechanism for a token-holder vote of roughly 48 hours, with disputed resolutions running 4 to 6 days in total. Winning tokens are then redeemable for $1.00 each.

Nineteen long-dated markets pay holding rewards on top, currently 3.25% annualized, variable at Polymarket's discretion and sampled hourly. Treat that as a tiebreaker, not a reason to hold a position you would otherwise exit. To cash out: Portfolio, Withdraw, recipient address, then token, amount and network, then confirm.

Step 6: Track smarter with the free tools

A market page gives you the price, not who is buying.

Whale tracker: the largest holders with Smart Money Scores, so you can see whether size is on your side. Pair it with the whale tracking guide.

Alerts feed: real-time alerts on large new positions, which often move before the displayed midpoint does.

Screener: filter by volume, price and anomalies to skip illiquid books.

Movers: the biggest 24-hour swings, where spreads widen and market orders fill badly.

Resolution calendar: everything resolving in the next 31 days, so you know when capital frees up.

Leaderboard, plus odds pages such as Fed rate decision odds and 2026 midterm odds.

Mistakes beginners make

Treating the midpoint as your fill. You pay the ask and receive the bid, and on a wide spread the round trip can cost more than your edge.

Market-ordering into a thin book, where the order walks the asks upward until your dollars are spent and you overpay.

Leaving limit orders open on sports, where they are automatically cancelled once the game begins, so a pre-game plan can quietly vanish.

Sizing as though 40 cents were a coin flip. A losing share goes to zero, so stake only what you can lose.

Frequently asked questions

What is the minimum trade on Polymarket?

There is no platform-wide minimum: Polymarket states its order book has no trading size limits and matches buyers and sellers of any amount. Each market does enforce its own minimum order size and price increment. In practice the deposit minimum for your network sets the floor.

Can you lose more than you put in?

Not on the main platform's event markets. A share is fully collateralized and can only fall to $0.00, so your maximum loss is what you paid. Perps are a different product: up to 20x leverage on major crypto, index and commodity markets and 10x on single stocks, liquidation once account equity falls below maintenance margin, the minimum a position must keep, and hourly funding capped at plus or minus 4% per hour. Read is Polymarket Perps safe, model a trade on the Perps calculator, and note that eligible readers outside the US and Canada can open Polymarket Perps subject to jurisdiction.

How long do withdrawals take?

Polymarket's developer documentation states that withdrawals are instant and free, with pUSD unwrapped to USDC and bridged to the chain and token you select. The help center gives the five-step flow but no timing figure, so speed depends on the destination network. Above $50,000 the docs suggest splitting the withdrawal to limit slippage.
