Polymarket Promo Code 2026: Sign Up Bonus & Referral Deals

Updated March 2026 — An honest guide to Polymarket promotions, referral links, and how to get the best deal when joining in 2026. We track Polymarket daily and cut through the noise about fake codes circulating online.

Does Polymarket Have Promo Codes?

If you've been searching "Polymarket promo code," "Polymarket discount code," or "Polymarket sign up bonus," you deserve a straight answer: Polymarket does not use alphanumeric promo codes the way sportsbooks like DraftKings or FanDuel do.

There is no POLY2026 or PREDSCOPE50 code you enter at signup for a guaranteed deposit match. Anyone claiming to have such a code on Reddit, YouTube, or coupon aggregator sites is either misinformed or actively trying to mislead you.

This is a deliberate product choice by Polymarket. As a prediction market — not a gambling site — Polymarket's model is built on fee revenue from trading volume, not on high-margin sportsbook bets. The platform's business doesn't lend itself to the same promotional playbook.

What does exist is a referral program, and the platform's fee structure itself is arguably the most valuable "bonus" any new user can receive. We'll cover both in detail below.

Why You Won't Find Promo Codes Elsewhere Either

Unlike a sportsbook that profits from the house edge on every bet, Polymarket makes money from a thin slice of trading volume. The economics simply don't support the kind of aggressive deposit-match promotions you see in sports betting. This isn't a negative — it's actually a sign that Polymarket is built as a trading platform, not a casino.

Polymarket Referral Link 2026

While Polymarket doesn't have promo codes, it does have a referral program. The referral system works as follows: when an existing user shares their referral link and a new user signs up through it and starts trading, both parties can receive benefits.

Our verified Polymarket referral link for 2026:

How the Polymarket Referral Program Works

When you sign up using a referral link:

• Your account is linked to the referring user at the time of registration
• After completing KYC (identity verification) and placing qualifying trades, both you and the referrer may receive trading credits
• The specific amounts and thresholds change periodically — check the Polymarket referral dashboard for current terms
• Referral benefits are typically credited in USDC directly to your account balance

How to Get Your Own Polymarket Referral Link

Once you're a Polymarket user, you can generate your own referral link to share with others:

1. Log into your Polymarket account
2. Navigate to your profile or the referral section (usually under Account Settings)
3. Copy your unique referral URL
4. Share it on social media, with friends, or on your own platform

Each referral that successfully trades earns you a commission. This is the legitimate "bonus" mechanism that Polymarket supports — not promo codes.

How to Sign Up on Polymarket — Step by Step

If you're new to Polymarket, here's the complete sign-up process as of 2026. Polymarket US now requires full KYC following CFTC approval in November 2025.

1. Go to Polymarket via referral link
   Visit polymarket.com/?r=OddsShift to ensure any referral benefits are tracked to your account.
2. Create an account
   Click "Sign Up" and register with your email address. You'll receive a verification email — confirm it before proceeding.
3. Complete KYC (US users)
   US users must verify identity with a government-issued ID, Social Security Number, and proof of address. This is required under CFTC regulations. Non-US users have different verification requirements.
4. Set up your wallet
   Polymarket uses a built-in smart wallet. For advanced users, you can connect an external wallet (MetaMask, Coinbase Wallet, etc.) on the Polygon network. New users are recommended to use the built-in wallet — it's simpler.
5. Deposit USDC
   Fund your account with USDC (USD Coin). You can buy USDC directly on Polymarket via credit/debit card, or transfer from Coinbase, Binance, or another exchange. See our full deposit guide for step-by-step instructions.
6. Browse markets and place your first trade
   Explore active markets on politics, economics, sports, and more. Use the trading guide to understand order types before committing real money. Consider starting with a small position to learn the interface.

Polymarket Deposit Bonus

Polymarket does not currently run a permanent deposit bonus program. There is no automatic "deposit $100, get $10 free" offer running at all times the way some sportsbooks maintain.

However, here's what can work in your favor:

Periodic Trading Promotions

Polymarket occasionally runs time-limited trading competitions and promotional markets with prize pools. Past examples include:

• Leaderboard competitions where top traders win USDC prizes
• Special markets with boosted payouts during major events (elections, World Cups)
• Free-to-play prediction contests during high-profile news cycles

These are announced on Polymarket's official Twitter/X account and in their app. There is no reliable third-party source for these — stick to official channels.

The Fee Advantage as a Structural Deposit Bonus

This is worth explaining carefully because it's genuinely valuable:

For active traders, this fee differential is worth hundreds or thousands of dollars per year. It's not a flashy promo code, but it's real money that compounds over time.

How to Get the Best Polymarket Deal

Since there's no promo code to enter, the way to maximize your value on Polymarket is through smart trading practices:

1. Use Limit Orders (Maker Strategy)

When you place a limit order that sits in the order book waiting to be filled, you pay 0% in trading fees. This is the maker strategy. Instead of clicking "Buy" at the current market price, set your desired price and wait. For patient traders, this eliminates explicit trading costs entirely.

2. Start Small to Learn the Interface

There's no minimum deposit, and even $20-50 is enough to explore the platform. New users often make avoidable mistakes (wrong order type, misunderstanding market resolution rules) that are much cheaper to make with small positions. Learn first, scale later.

3. Target High-Liquidity Markets

The bid-ask spread is your main trading cost on Polymarket. In deep, liquid markets (major elections, Fed rate decisions, large crypto events), spreads are often just 1-3 cents. In thin markets, spreads can be 10-20+ cents, significantly increasing your effective cost. Stick to the most-traded markets when starting out.

4. Trade Free Markets First

Polymarket occasionally features free prediction markets — paper trading or contest-style markets that cost nothing to enter. These are valuable for learning market mechanics without real money at risk. Check the "Free" or "Demo" sections when available.

5. Avoid Buying Near Resolution

As a market approaches its resolution date, liquidity often dries up and spreads widen. Entering a position when a market is close to resolving (with high confidence) usually means paying a steep spread premium. The best value trades come from entering early when uncertainty is high and prices are more rational.

Polymarket vs Kalshi Bonuses

Since many traders compare these two platforms, here's how the bonus and fee landscape stacks up:

Bottom line: Kalshi occasionally has more conventional promotional offers, but Polymarket's structural fee advantage makes it cheaper to trade on over any significant time horizon. If you're trading actively, the fee savings on Polymarket outpace any one-time Kalshi bonus after just a few weeks of trading.

For a deeper comparison, see our Kalshi Review and the Best Prediction Markets 2026 guide.

Polymarket Fee Structure

Understanding Polymarket's fees helps you see why the platform doesn't need to offer traditional bonuses — it already offers outstanding value through its pricing model. For the full breakdown, see our Polymarket fees guide.

Why This Is Better Than Traditional Betting

In a sportsbook, the house edge is baked into every line. A 50/50 coin-flip bet might be offered at -110/-110, meaning you bet $110 to win $100. That's a 4.5% vig, and it applies to every single bet, regardless of promotions.

On Polymarket, you're trading against other humans in an open order book. If you place a limit order, you pay literally 0% in fees. The "edge" is only the bid-ask spread between buyers and sellers — and in liquid markets, that spread is a fraction of what any sportsbook charges.

A $100 sportsbook bet costs ~$4.50 in expected value to the house. A $100 Polymarket limit order costs $0. Over 100 trades, that's a $450 difference that stays in your pocket.

Common Questions About Polymarket Codes

Scam Warning: Fake Polymarket Promo Codes

Warning: There are no legitimate Polymarket promo codes circulating online.

A recurring pattern: someone posts a "Polymarket promo code" on Reddit, a coupon site, or a YouTube video. The codes look plausible (POLY100, PMBONUS, etc.). When users try them, they find the codes don't work — because Polymarket has no promo code system.

In more sophisticated scams, a fake "Polymarket" site with a similar domain will accept the code and ask for your wallet credentials or seed phrase. Never enter your wallet seed phrase anywhere except your official wallet app.

How to Verify Legitimate Polymarket Offers

The only trusted sources for Polymarket promotions are:

• Polymarket's official website: polymarket.com
• Official Twitter/X: @Polymarket
• Official Discord (linked from the Polymarket website)
• Verified partners with published referral links (like this page)

If you find a "Polymarket promo code" somewhere that isn't one of the above sources, it's either wrong or a scam. Don't enter it anywhere, and don't click links that claim to apply the code automatically — they may be phishing links.

What About Polymarket Codes on Reddit?

Reddit threads about Polymarket promo codes are nearly always one of three things:

• Outdated — a code from a limited past promotion that has since expired
• Misinformed — someone confusing Polymarket with a sportsbook that uses promo codes
• Deliberate misinformation — posted to drive traffic to scam sites or collect referral cookies

When someone in a Reddit thread claims to have a working Polymarket code, ask them for proof of it working (screenshot from their account) before attempting to use it. Legitimate referral links are transparent about what they are.

How Polymarket Referral Bonuses Work

Polymarket's referral program is the closest thing to a traditional "bonus" on the platform. Understanding exactly how it works will help you get the most out of signing up. Here is a detailed breakdown of the referral mechanics as of April 2026.

The Referral Link Format

Every Polymarket referral link follows the same structure: polymarket.com/?r=CODE, where CODE is the unique identifier assigned to the referring user. For example, our referral link is polymarket.com/?r=OddsShift. When you click a referral link, Polymarket tracks the referral via a cookie stored in your browser, so make sure you don't clear cookies before completing registration.

What New Users Receive

When you sign up through a valid referral link and meet the qualifying criteria, Polymarket credits your account with a trading bonus. The current structure works as follows:

• Referral bonus amount: Up to $20 in USDC trading credits for new users who sign up via referral link
• Minimum deposit: You must deposit at least $50 in USDC to activate the referral bonus
• Trading requirement: You need to place at least one qualifying trade (minimum $10 position) within 30 days of account creation
• KYC completion: Full identity verification must be completed before the bonus is credited
• Payout timeline: Once all conditions are met, the bonus is typically credited to your account within 48-72 hours

What the Referrer Receives

The person who shared the referral link also benefits. As of 2026, referrers earn a percentage of the trading fees generated by the users they refer. Since Polymarket's fees are already extremely low, this is a volume-based reward — referrers who bring in active traders benefit the most. The referral commission is ongoing, not a one-time payment, which incentivizes referrers to recommend the platform to people who will genuinely use it.

Bonus Unlock Conditions in Detail

The referral bonus does not appear in your account immediately upon signup. Here is the exact sequence of events:

1. Click the referral link — the referral is tracked via a browser cookie (valid for 30 days)
2. Create your account — register with your email and verify it
3. Complete KYC — submit your government ID, SSN (US users), and proof of address. This process typically takes 5-15 minutes, with approval in under 24 hours
4. Deposit at least $50 USDC — fund your account via credit/debit card, bank transfer, or crypto transfer
5. Place a qualifying trade — buy or sell at least $10 worth of shares in any active market
6. Bonus credited — the USDC bonus appears in your account balance within 48-72 hours after all conditions are met

Wagering Requirements

Unlike sportsbook bonuses that often come with punishing rollover requirements (bet the bonus amount 10x before withdrawing), Polymarket's referral bonus has no traditional wagering requirement. Once the bonus is credited to your USDC balance, it is yours to trade with or withdraw. There is no "play-through" requirement. This is a significant advantage over platforms like DraftKings or FanDuel, where bonus funds are typically locked behind aggressive rollover terms.

Referral Limits and Restrictions

• Each new user can only use one referral link — the first one clicked before registration
• Self-referrals (creating multiple accounts to claim bonuses) are prohibited and will result in account suspension
• Referral bonuses are subject to change — Polymarket may adjust amounts or conditions at any time
• Users in restricted jurisdictions may not be eligible for the referral program
• There is no limit on how many people a single referrer can invite

Step-by-Step: Claiming Your Polymarket Bonus

This detailed walkthrough covers every step from clicking the referral link to receiving your bonus in your account. Follow these steps carefully to ensure your referral is tracked correctly and your bonus is activated.

Step 1: Set Up MetaMask (Optional but Recommended for Advanced Users)

While Polymarket now offers a built-in smart wallet for most users, some traders prefer to use MetaMask for greater control over their funds. If you want to use MetaMask:

• Download MetaMask from metamask.io (browser extension or mobile app)
• Create a new wallet and securely store your 12-word seed phrase — write it down on paper, never store it digitally
• Add the Polygon network to MetaMask (Polymarket operates on Polygon for low gas fees). Go to Settings > Networks > Add Network and enter the Polygon mainnet details, or use the "Add Polygon" button that appears when connecting to Polymarket
• Ensure you have a small amount of MATIC (Polygon's native token) for gas fees — usually less than $0.10 worth is sufficient for dozens of transactions

If you are new to crypto, skip MetaMask and use Polymarket's built-in wallet instead. It handles all the blockchain complexity for you.

Step 2: Click the Referral Link

Visit polymarket.com/?r=OddsShift in your browser. Important details:

• Use the same browser you will register with — the referral is tracked via cookies
• Do not use incognito/private browsing mode, as cookies may not persist
• If you are using a VPN, ensure it is set to a non-restricted country (more on this in the mistakes section below)
• The referral cookie is valid for 30 days, but it is best to complete registration immediately after clicking

Step 3: Create Your Account

Click "Sign Up" on the Polymarket homepage. You can register with:

• Email address — the most common method. You will receive a verification email within minutes
• Google account — one-click sign-up via Google OAuth
• Apple ID — available for iOS users
• Wallet connection — connect MetaMask or another Web3 wallet directly

After choosing your method, verify your email address by clicking the link in the confirmation email. Check your spam folder if you do not see it within 5 minutes.

Step 4: Complete Identity Verification (KYC)

US-based users must complete full KYC, which was mandated after CFTC approval in November 2025. The verification process requires:

• Government-issued photo ID — passport, driver's license, or state ID
• Social Security Number (US users only)
• Proof of address — utility bill, bank statement, or official letter dated within the last 3 months
• Selfie verification — a live photo to match against your ID

The automated verification usually completes in 5-15 minutes. In rare cases, manual review can take up to 24-48 hours. You will receive an email notification when your account is approved.

Step 5: Deposit USDC to Activate the Bonus

To activate the referral bonus, you need to deposit at least $50 in USDC. Polymarket supports multiple deposit methods:

• Credit/debit card — buy USDC directly on Polymarket via the MoonPay integration. Processing fee of ~2.5% applies, but it is the fastest method (instant)
• Bank transfer (ACH) — lower fees but takes 1-3 business days to arrive
• Crypto transfer — send USDC from Coinbase, Binance, Kraken, or any exchange to your Polymarket wallet address on the Polygon network. This is the cheapest method (near-zero fees) and takes 2-5 minutes
• Bridge from Ethereum — if you have USDC on Ethereum mainnet, use the Polygon Bridge or a third-party bridge to move it to Polygon. Takes 10-30 minutes

For a full walkthrough of each deposit method, see our How to Deposit on Polymarket guide, or if you need to acquire USDC first, check our How to Buy USDC for Polymarket guide.

Step 6: Place Your First Trade

To complete the referral bonus requirements, place at least one trade worth $10 or more. Here is how to make your first trade:

1. Browse the Popular or Trending tab on the Polymarket homepage to find an active market
2. Click on a market to view its order book, price chart, and resolution criteria
3. Decide whether you want to buy Yes or No shares
4. Choose your order type: Market order (instant fill at current price) or Limit order (set your own price and wait for a fill — this gives you 0% maker fees)
5. Enter the dollar amount you want to trade (at least $10 for the bonus qualification)
6. Review the order details — check the number of shares, the price per share, and the potential payout
7. Click Confirm to execute the trade

Step 7: Receive Your Bonus

After completing all the steps above — referral link click, account creation, KYC, $50+ deposit, and $10+ qualifying trade — your bonus will be credited within 48-72 hours. You will see it as a USDC credit in your account balance. No action is needed on your part after this point; the bonus appears automatically.

Polymarket Promotions Calendar 2026

While Polymarket does not run a fixed promotional schedule like sportsbooks do, the platform has developed a pattern of running special events and promotions around major news cycles and sporting events. Based on past patterns and official announcements, here is what to expect in 2026.

Q1 2026: Super Bowl & March Madness Season

• Super Bowl LX (February 2026): Polymarket ran enhanced markets around the Super Bowl, including prop-style event markets (first team to score, halftime show moments, national anthem duration). Trading volume surged 300%+ during Super Bowl week, creating tighter spreads and better opportunities for new traders
• March Madness (March 2026): NCAA tournament markets on Polymarket saw significant activity. Polymarket introduced bracket-style markets where traders could bet on Round of 64 outcomes through to the championship. A $10,000 prize pool leaderboard ran for the tournament duration
• Referral bonus bump: During Q1 2026, Polymarket temporarily increased referral bonuses to attract new users ahead of the sports season

Q2 2026: World Cup & Midterm Election Primaries

• FIFA World Cup 2026 (June-July): The 2026 World Cup, co-hosted by the US, Mexico, and Canada, is expected to be one of the highest-volume events in Polymarket history. Expect special markets on group stage outcomes, golden boot winner, surprise eliminations, and host country performance. Polymarket has signaled major promotional activity around the tournament
• US Midterm primaries: As primary elections ramp up, Polymarket typically launches new markets and may offer trading competitions focused on political prediction accuracy
• Deposit match events: Historically, Polymarket has run limited-time deposit match promotions (e.g., "deposit $100, get $10 in trading credits") during peak event periods. Watch official channels for announcements around the World Cup

Q3 2026: Summer Markets & Tech Events

• Crypto and tech markets: Bitcoin halving cycle effects, major tech earnings, AI milestones — Polymarket runs special markets around these events with occasional leaderboard competitions
• Olympic-related markets: If relevant international sporting events are active, expect themed promotions
• Back-to-school trading competition: Polymarket has previously run "fantasy prediction" competitions targeting younger demographics returning from summer break

Q4 2026: US Midterm Elections

• November midterm elections: This is Polymarket's peak period. The 2024 presidential election drove over $3.5 billion in trading volume. The 2026 midterms — covering all 435 House seats, 33-34 Senate seats, and numerous governorships — will generate enormous activity
• Election prediction contests: Expect free-to-play prediction competitions with substantial USDC prize pools. Polymarket ran similar contests during the 2024 election cycle
• Enhanced referral rewards: Referral bonuses are likely to be temporarily increased during peak election season to capitalize on organic interest in prediction markets
• Special resolution markets: Watch for "speed markets" that resolve within hours of polls closing — high-action opportunities for experienced traders

Maximizing Your Polymarket Bonus

Once you have signed up and received your referral bonus, here are proven strategies to make the most of your initial capital as a first-time trader. These approaches minimize risk while helping you learn the platform effectively.

Strategy 1: Start With High-Probability Events

As a new trader, your first goal should be capital preservation while learning the interface. High-probability events — markets where one outcome is trading at 85-95 cents — offer a relatively safe way to earn your first profits:

• A market trading at $0.92 for "Yes" means you invest $0.92 to potentially win $1.00 — an 8.7% return if the event occurs
• These markets have lower variance, meaning your initial capital is less likely to experience dramatic swings
• Look for events with clear, unambiguous resolution criteria — "Will the Federal Reserve cut rates in June 2026?" is better than subjective markets with interpretation risk
• Check the market volume and liquidity before entering: higher-volume markets have tighter spreads and are easier to exit if you change your mind

Strategy 2: Use Limit Orders for Zero Fees

This cannot be emphasized enough: limit orders on Polymarket carry 0% maker fees. For every trade you place, you should be asking "Can I use a limit order instead of a market order?"

• When you place a limit order, you specify the exact price you are willing to pay. Your order sits in the book until someone else trades against it
• Set your limit price 1-2 cents better than the current ask price. For a market with Yes at $0.65/$0.67 (bid/ask), place a limit buy at $0.66. You get a better price than market order AND pay zero fees
• Limit orders also protect you from slippage — the risk that the price moves between when you click "buy" and when the order executes
• The trade-off: limit orders may not fill immediately. For time-sensitive trading (breaking news events), market orders are sometimes necessary

Strategy 3: Diversify Across 3-5 Markets

Do not put all your capital into a single market. Prediction markets, like any form of trading, carry uncertainty. Diversification reduces the impact of any single loss:

• Split your capital across 3-5 uncorrelated markets — for example, one political market, one economic market, one sports market, one tech market, and one cultural/entertainment market
• Avoid correlated positions — if you bet "Yes" on the incumbent winning re-election AND "Yes" on the incumbent's party winning the Senate, those two positions are highly correlated. A single election surprise could hit both
• Position sizing: No single position should exceed 25-30% of your total capital as a beginner. With $70 ($50 deposit + $20 bonus), that means no single trade larger than $17-21
• Leave some dry powder: Keep 20-30% of your account in uninvested USDC. New opportunities arise constantly, and having cash available lets you act quickly without selling existing positions at bad prices

Strategy 4: Compound Your Returns

As your winning trades resolve, reinvest the profits into new positions rather than immediately withdrawing. Compounding works powerfully even with modest returns:

Strategy 5: Track Your Performance

Keep a simple spreadsheet or notes file tracking every trade: the market, your entry price, your reasoning, and the outcome. After 20-30 trades, patterns will emerge — you will see which types of markets you predict well and which ones you consistently get wrong. Double down on your strengths and reduce exposure to your weak areas. Many successful Polymarket traders attribute their edge to systematic self-review rather than any single brilliant prediction.

Polymarket vs Kalshi vs Robinhood Sign-Up Bonuses

If you are comparing prediction market platforms in 2026, here is a comprehensive comparison of sign-up offers, referral bonuses, and fee structures across the three major platforms.

Which Platform Bonus Is Actually Worth the Most?

At face value, Kalshi's $25 referral bonus looks slightly better than Polymarket's $20. But the real comparison is about total cost of trading, not just the sign-up bonus:

Robinhood's prediction market offering (launched via event contracts in 2025) charges no explicit fees but has a very limited selection of markets — typically only major political and economic events. If you want variety and depth, Polymarket or Kalshi are the better choices. If you are already a Robinhood user and want to dabble casually, their event contracts are a fine starting point.

For detailed platform breakdowns, see our Kalshi Review, Robinhood Prediction Markets guide, and the comprehensive Best Prediction Markets 2026 ranking.

Common Promo Code Mistakes to Avoid

Based on thousands of user reports and community discussions, here are the most frequent mistakes people make when trying to claim a Polymarket bonus or referral reward. Avoid these pitfalls to ensure your sign-up goes smoothly.

Mistake 1: Using Expired or Fake Promo Codes

This is the single most common mistake. As we have explained throughout this guide, Polymarket does not use alphanumeric promo codes. There is no text box at signup where you enter a code. If someone on Reddit, YouTube, TikTok, or a coupon site gives you a code like "POLY2026" or "PMBONUS50," it is not real. You will waste time trying to find where to enter it, because the entry point does not exist.

What actually works: referral links in the format polymarket.com/?r=CODE. These are URLs, not text codes. You click them; you do not type them into a box.

Mistake 2: VPN Interference

Using a VPN can cause problems with Polymarket registration and bonus activation:

• Geographic restrictions: If your VPN routes through a restricted country, your account may be flagged or registration may be blocked. Polymarket is available in the US (since CFTC approval) but is restricted in some jurisdictions
• KYC mismatch: If your VPN location does not match the country on your identity documents, KYC verification may fail or be delayed
• Referral tracking: Some VPN configurations block or interfere with cookies, which means the referral link may not be properly tracked to your account. If you must use a VPN, ensure it allows cookies from polymarket.com
• Best practice: Disable your VPN during the registration and first deposit process. You can re-enable it afterward for regular browsing if desired

Mistake 3: Not Meeting the Minimum Deposit

Signing up via a referral link but depositing less than the required minimum ($50 USDC as of April 2026) means your bonus will not activate. Many new users deposit $20 or $30, thinking any amount qualifies, then wonder why they did not receive the bonus. Always check the current minimum deposit requirement — it is displayed on the referral landing page and in the account dashboard under the referral section.

Mistake 4: Sending Funds to the Wrong Wallet or Network

This is a costly and unfortunately common error for crypto newcomers:

• Wrong network: Polymarket operates on the Polygon network. If you send USDC on Ethereum mainnet to your Polymarket wallet address, the funds may not appear. Always double-check that you are sending on Polygon (also called Polygon PoS)
• Wrong token: Send USDC (USD Coin) specifically, not USDT (Tether), DAI, or other stablecoins. Polymarket's trading system uses USDC exclusively
• Wrong address: Copy your Polymarket wallet address directly from the app's deposit page. Do not manually type wallet addresses — a single wrong character means the funds are sent to someone else (or lost forever)
• Recovery: If you send funds on the wrong network, they are sometimes recoverable but the process is complex. Our deposit guide covers this in detail

Mistake 5: US Restrictions and CFTC Compliance

Since Polymarket received CFTC approval in late 2025, US users can trade legally — but with specific requirements:

• Full KYC is mandatory for US-based users. You cannot trade (and therefore cannot qualify for the referral bonus) without completing identity verification
• Certain market types may be restricted for US users based on CFTC classification. If a market is unavailable in your jurisdiction, it will not count toward your qualifying trade requirement
• Tax reporting: Polymarket profits are taxable income in the US. This does not affect your bonus, but many new users are surprised by this. See our Prediction Market Taxes guide for details

Mistake 6: Clearing Cookies Before Completing Registration

The referral link works by setting a cookie in your browser. If you click the referral link, then clear your browser cookies (or switch browsers, or switch devices) before completing registration, the referral will not be tracked. Best practice:

1. Click the referral link
2. Complete registration, KYC, and first deposit in the same browser session
3. Do not clear cookies or use browser cleaning tools until after your first trade is placed

Mistake 7: Trying to Stack Multiple Referral Links

You can only use one referral link per account. Clicking multiple referral links before signing up does not stack bonuses — only the most recent (or in some cases, the first) referral link is tracked. Do not waste time trying to combine offers from different sources. Pick one trusted referral link and use it. Ours: polymarket.com/?r=OddsShift.
