How to Sign Up for Polymarket in 2026 (Step-by-Step)

Getting started on Polymarket is more straightforward in 2026 than it's ever been for US users — the platform relaunched in the United States in December 2025 following CFTC regulatory approval, which means American participants can sign up directly without any workarounds. The process still involves a crypto wallet and USDC rather than a standard bank deposit, which makes it different from fiat-native platforms, but once you understand the logic it moves quickly. I've walked through the full onboarding flow and the guide below lays out every step so nothing catches you off guard.

Before diving in, it's worth understanding what you're actually signing up for. Polymarket is a prediction market built on the Polygon blockchain where you purchase contracts on real-world events — elections, economic data, sports outcomes, geopolitical news. The contract price at any moment reflects the market's implied probability of that outcome occurring, and correct predictions pay out $1 per contract at resolution. Our full Polymarket review covers the platform in depth if you want the complete picture before depositing anything.

One heads-up for US users before you start: while you can now sign up and participate freely at the federal level, sports and entertainment contract availability may vary by state due to ongoing litigation between prediction market platforms and state gaming regulators. Nevada specifically has court-ordered restrictions on those market categories. Political and economic markets are unaffected. If sports contracts are your primary interest, check what's available in your state when you log in.

This guide covers everything from wallet setup through your first market position. Before the steps, here are the companion resources worth bookmarking: our Polymarket promo code page for the latest sign-up bonus, the full Polymarket platform review for a complete platform analysis, and our guide on Polymarket's US legal status for the regulatory background. Now let's get into the process.

1. Step 1 — Download a Compatible Crypto Wallet Polymarket works with browser-based and mobile crypto wallets. MetaMask and Coinbase Wallet are the two most commonly used options. Download your preferred wallet as a browser extension (Chrome and Firefox both work) or as a mobile app. Create a new wallet if you don't already have one, and write down your seed phrase — store it somewhere secure and offline. This seed phrase is the only way to recover your wallet if you lose access to your device.
2. Step 2 — Visit Polymarket and Connect Your Wallet Go to polymarket.com and click the sign-up or connect wallet button in the top right corner. Select your wallet type, approve the connection request that pops up in your wallet extension or app, and you'll be taken into the Polymarket onboarding flow. The site never holds your private keys — the wallet connection is non-custodial. US users can connect directly without any geo-restrictions as of December 2025.
3. Step 3 — Complete Your Profile and Email Verification Polymarket will ask you to enter an email address. This isn't used for a traditional login — instead it allows account recovery via a magic link if your wallet becomes inaccessible. Enter a real email you control, confirm it, and your account shell is now live. You can also set a display name at this stage if you'd like one visible on leaderboards.
4. Step 4 — Add MATIC to Your Wallet for Gas Fees Polymarket runs on the Polygon network, which means every transaction requires a small amount of MATIC to cover network gas fees. These fees are tiny — typically fractions of a cent — but your wallet needs some MATIC to function. Purchase MATIC through Coinbase, Binance, or any major exchange and send it to your wallet address on the Polygon network. Make sure you're sending on the Polygon network specifically, not Ethereum mainnet.
5. Step 5 — Deposit USDC Into Your Polymarket Account Polymarket uses USDC as its trading currency. Acquire USDC on the Polygon network and transfer it to your connected wallet address. You can buy USDC on a centralized exchange like Coinbase, then send it to Polygon, or use the in-app onramp that Polymarket provides via third-party services like MoonPay. Once USDC appears in your wallet, click "Deposit" inside Polymarket to move funds into your trading account. Confirm the transaction in your wallet when prompted.
6. Step 6 — Browse Markets and Purchase Your First Contract With USDC deposited, you're ready to trade. Browse market categories — politics, sports, economics, world events — and click any market that interests you. Each market presents a Yes or No position. Click the outcome you believe will happen, enter the USDC amount you want to put in, review the contract price (which reflects the implied probability of that outcome), and confirm the trade. The transaction settles on-chain in seconds and your position appears in your portfolio immediately.

Setting Up Your Crypto Wallet for Polymarket

The wallet setup step is where most newcomers slow down, so it's worth spending a little extra time here. MetaMask is the most widely used option and has extensive documentation, making it the easiest choice for first-timers. Coinbase Wallet is a strong alternative if you're already using Coinbase as your exchange, since it integrates smoothly with the platform.

Once your wallet is installed, configure it to use the Polygon network rather than the Ethereum mainnet. In MetaMask, add the Polygon network through Settings → Networks → Add Network, or use chainlist.org to add it automatically in one click. Coinbase Wallet handles network switching from within the app. After switching to Polygon, any USDC or MATIC you send to your wallet address on that network will show up and be usable on Polymarket.

If you're used to prediction platforms that don't require crypto — like those offering a PrizePicks promo code for a straightforward cash deposit — the wallet setup will feel like more friction upfront. It is. But once it's done, the non-custodial structure means you fully own your funds at every point, which is a meaningful difference from platforms that hold your balance on your behalf.

Depositing USDC: Buying and Bridging Explained

Getting USDC into your Polymarket account is the most technically involved part of this process, and there are two main paths. The simpler route is using Polymarket's native onramp, which lets you buy USDC directly with a debit card or bank transfer without leaving the platform. Availability varies by region, and fees from third-party onramp providers are typically a few percentage points, but the convenience is hard to beat for first-time users.

The second path is buying USDC on a centralized exchange — Coinbase, Kraken, and Binance all support it — and withdrawing to your wallet on the Polygon network. When you initiate a withdrawal from the exchange, always double-check that you're selecting Polygon as the network. Sending USDC on the Ethereum mainnet to a Polymarket wallet configured for Polygon is a recoverable mistake but creates unnecessary hassle and costs extra gas fees. A bridging option also exists if you already hold USDC on Ethereum mainnet via the Polygon Bridge or a third-party bridge like Across Protocol — but this is the most advanced path and not recommended for newcomers.

Polymarket Sign-Up: What to Know Before Your First Trade

Polymarket markets resolve based on publicly verifiable real-world outcomes, determined by the UMA decentralized oracle system. Winning contract holders receive $1.00 per share at resolution; losing contract holders receive nothing. The contract price you see when entering a position reflects the market's implied probability of that outcome — a contract priced at $0.65 implies a 65% chance of resolution in your favor.

There are no platform fees for trading in the traditional sense, but you'll pay a small spread when entering and exiting positions and minor gas fees on each on-chain transaction. These are typically negligible unless you're making many small trades. Withdrawing USDC back to your wallet follows the same process in reverse — you initiate a withdrawal from within the platform, confirm the transaction, and funds return to your connected wallet, where you can send them to an exchange or hold them.

If Polymarket's crypto-native structure feels like too much overhead right now, platforms like those featured with an Underdog Fantasy promo code offer prediction-style markets with standard cash deposits and withdrawals, and are fully available to US residents. They're a different product, but worth knowing about depending on your comfort level with crypto infrastructure.

How to Sign Up for Polymarket: Final Verdict

Polymarket's sign-up process has a steeper learning curve than most prediction platforms, but it's not complicated once you understand the logic behind it. The wallet-first approach is what gives Polymarket its non-custodial edge — you own your funds throughout, and there's no centralized account that can be frozen or suspended. For anyone comfortable with crypto basics, the setup takes under 20 minutes and only needs to be done once. The steps that trip people up most often are network selection when depositing (always confirm Polygon) and forgetting to hold a small amount of MATIC for gas. Get those two things right and the rest is straightforward. With US access now fully restored, Polymarket's depth of markets and global liquidity make it one of the strongest prediction platforms available to American participants.
