Polymarket US App Review May 2026: The Complete Guide for US Users

Polymarket is a safe and legitimate prediction market platform for US users. It operates under federal oversight and has been active globally since 2020. The company also received a $2 billion investment from Intercontinental Exchange, which adds another layer of credibility. 

Polymarket left the US market in 2022 after a $1.4 million CFTC settlement over unregistered event contracts, then returned in late 2025 by acquiring QCEX for $112 million. That deal gave Polymarket a licensed US derivatives exchange and clearinghouse, which is the compliance base it needed to serve American users again.

The US Polymarket app is a separate product from the global platform. It launched on iOS in December 2025 and rolled out the Android app in 2026. 

Polymarket is available in all states except Nevada, but sports event contracts can vary by state due to legal disputes with state regulators.

Polymarket Bonuses and Incentives

Polymarket offers a $50 sign-up bonus for new US users who deposit at least $20.

There are no market-type restrictions attached to the offer. You can use the bonus on sports, politics, or any other contract available in the Polymarket app. f you want to see how this stacks up against other platforms, you can check out the best prediction market bonus options currently available.

Polymarket Sign-Up Bonus — Deposit $20, Get $50

New Polymarket US users can get $50 in bonus funds after depositing $20 or more. No promo code is required.

Profits from winning trades placed with bonus funds are withdrawable as cash. The offer isn’t available in Nevada.

Here’s how to claim the Polymarket US welcome bonus.

1. Download the Polymarket app on iOS or Android.

2. Sign up with your email address or phone number.

3. Complete identity verification with your SSN and a government-issued ID.

4. Deposit $20 or more via debit card, ACH, Apple Pay, or wire transfer.

5. Receive $50 in bonus trading funds automatically.

The offer is for new users only, with one bonus per account. 

Daily Liquidity Rewards

Polymarket US runs daily liquidity rewards for traders who post limit orders on eligible markets.

The payout is based on how close your limit orders are to the current market midpoint. Orders placed closer to the market midpoint can earn a larger share of the daily USDC reward pool.

You need at least $1 in accrued rewards before Polymarket issues a payout. The program is available to all users and runs continuously.

Polymarket User Experience

Polymarket is app-only in the US. There’s no desktop site or browser trading, so you’ll need the iOS or Android app to get started.

By default, contracts on the app appear as color-coded probability buttons rather than traditional prices, making it easy to scan prices without much mental math. You can switch the display in Settings if you prefer another view. Polymarket supports percent, cents, American price format, and multiplier formats.

The home screen puts trending markets near the top, along with live events grouped by sport. Navigation runs across the top, with categories such as Home, Politics, NBA, MLB, Golf, NHL, ATP, WTA, EPL, MLS, UCL, La Liga, and more.

There’s also a Live tab for in-progress events. From there, you can filter by sport instead of jumping between categories one by one.

Market pages include price history charts with 1H, 1D, and 1W views. This allows you to see how a market moves after news, injuries, lineup changes, or trading pressure before you enter a position.

The trade slip works in dollars, not contract count. You type how much you want to spend, and the app shows the estimated payout, how many contracts you’re buying, and the current price before you swipe to confirm.

Open trades are available in the Portfolio tab. You can track current value, entry price, and unrealized gain or loss, then sell before settlement if another trader is willing to take the other side.

Order Book and Limit Orders

Polymarket US supports limit orders and gives traders full order book access. The order book shows live bids and asks, including the price, number of shares, and total dollar amount available at each level.

Limit orders give you more control over your entry price. Instead of taking the current market price, you can post the price you want, set an expiration time, and wait for another trader to match it.

This is useful if you’re trading with bonus funds or placing larger positions. A few cents on entry can change your return, and Polymarket gives you a way to avoid taking the first price on the screen.

Polymarket also includes a Trading API inside Settings. After completing KYC, programmatic traders can create Ed25519 API credentials through the developer portal.

That makes Polymarket one of the more advanced US prediction market apps for traders who want both a consumer app and API access.

Polymarket Markets Available

The Polymarket app is built mostly around sports right now. It covers a dozen sports categories, while non-sports markets are still more limited.

Traders can take positions on all major sports, NCAAB, NCAAF, WNBA, tennis, golf, UFC, and soccer. If you want to explore how these offerings compare to alternative platforms, taking a look at a breakdown of the best prediction markets can give you a broader look at the industry landscape.

Within each sport, you can trade moneylines, spreads, totals, and futures. Player props are available, including MLB markets for home runs and strikeouts, as well as NBA player props.

Futures are available across most major sports. The NBA futures section includes team-by-team championship probability contracts, an NBA MVP market, and season-long totals.

Polymarket US also offers trading on live sports events. The Live tab shows in-progress events with scores, game time, and current implied probabilities that update during play.

Non-sports markets are more limited at this stage. Polymarket currently covers politics and weather, with markets such as the 2026 House Midterm Winner, international elections, policy outcomes, and weather events for select US cities.

Polymarket US Banking & Fees

Polymarket’s costs come from two places: trading fees and banking fees. The good news is that both are on the lighter side compared with most US prediction market apps. 

Polymarket Trading Fees

Polymarket charges taker fees using a probability-based formula. In plain English, the fee varies with the contract price.

Fees are highest when a contract trades near $0.50, then get lower as the price moves closer to $0 or $1. Polymarket’s taker fee formula is Fee = Theta x C x p x (1 minus p), where Theta is the fee coefficient, C is the number of contracts, and p is the contract price.

In practice, taker fees range from $0.0005 to $0.0125 per contract, depending on the contract price. A trader taking the current price in a balanced 50/50 market pays more than a trader buying a longshot or near-certain outcome.

Maker orders work differently. If you post a limit order and add liquidity to the market, Polymarket doesn’t charge a trading fee. You can earn a small rebate instead.

That makes Polymarket more attractive to traders willing to wait for the price to move. If you’re posting limit orders instead of taking the first price available, your trading costs can drop fast.

Polymarket is cheaper than Kalshi on a similar fee model. Kalshi uses a 7% coefficient, while Polymarket uses 5%, which makes Polymarket roughly 29% cheaper per trade at typical contract prices. We go into more details in our direct Polymarket vs Kalshi comparison.

Polymarket also compares well against FanDuel Predicts, which charges a flat 2% fee on potential payout. For most position sizes and trading styles, Polymarket is the cheaper platform.

Polymarket Deposits & Withdrawals

Polymarket US supports four deposit methods: debit card, ACH bank transfer, Apple Pay, and wire transfer. There’s no listed minimum deposit for debit card, ACH, or Apple Pay.

The daily limit across all methods is $50,000. Every deposit must come from an account in your own name.

Debit card and ACH deposits give you instant buying power, so you can trade right away while your deposit is still being processed. The tradeoff is that withdrawals aren’t available until the deposit fully clears.

For ACH and debit card deposits, clearing usually takes three to four business days.

Polymarket doesn’t charge deposit or withdrawal fees. Wire transfers are the fastest withdrawal option, usually taking one business day.

Debit card and ACH withdrawals take three to four business days. Withdrawals must go back to the original funding source.

Polymarket Customer Support

Polymarket US offers support through email, Discord, and its in-app Help Center. There is no live chat, so users who want instant support may find it a little limited.

Available support options include:

• Email: support@polymarket.us for general US app issues

• KYC/onboarding email: onboarding@polymarket.us

• Discord ticket: Available through the in-app Settings screen

• In-app Help Center: Available through the book icon on market pages

The main Polymarket US customer support email is support@polymarket.us for general US app issues. For account verification or KYC questions, Polymarket lists the email address onboarding@polymarket.us.

Discord is available through the app Settings screen under Join the Discord. From there, you need to open a ticket in the Support sidebar, which creates a private conversation with a Polymarket team member.

Polymarket marks team members in blue font on Discord. The app also warns users not to respond to unsolicited DMs, which is good advice because scam attempts are common in prediction market communities.

The Help Center is available through the book icon on each market page. It’s useful when you want to check rules for a specific contract before placing a trade.

Support was checked more than once during the review period, including during regular US daytime hours. An email response to a sports contract settlement question arrived in about four hours, while the Discord ticket flow was useful for app navigation and account questions. The strongest part of the support test was technical accuracy: the reply addressed the contract’s resolution criteria directly.

Tax documents are available directly in Settings. That’s a useful feature for traders who need trade history and tax records at the end of the year.

Polymarket US Quick Overview

Polymarket Final Verdict

Three years away from the US market, Polymarket came back with the most trader-friendly fee structure in the space, an interface that doesn't make you trade with one hand tied behind your back, and enough liquidity on major sports markets to take it seriously as a primary platform.

The sports product is where Polymarket US makes its bones. Player props, live trading, a full order book, and price history on every contract. For a trader who spends most of their time on the NBA, MLB, or the major soccer leagues, Polymarket US is a tough act to follow in terms of combined cost and execution quality.

Polymarket US is early-stage in the best and most literal sense of the word. Two non-sports categories, no live chat or desktop platform. Those aren't dealbreakers, but they're the difference between a finished product and one that still has a runway ahead of it. Polymarket knows what it's building toward. The question is how fast it gets there. 

None of this is a free pass, though. Step outside sports, and the menu thins out to two categories. Desktop users don't have a product to work with yet. And anyone who's ever needed to sort out a live account issue knows exactly how much a missing live chat hurts when the clock is ticking. 

The takeaway is simple: if sports trading is where you spend most of your time and you want the best possible combination of fees, tools, and liquidity, Polymarket is the call. If you want to trade Fed decisions and culture markets on the same platform where you're fading NBA spreads, Kalshi covers more ground than any other platform right now. Either way, Polymarket's return to the US market has made the space more competitive, and that's good for everyone trading in it.

Responsible Risk Management

Polymarket US contracts are fully funded upfront. When you place a trade, the money is already committed, and a contract that resolves against you can lose the full amount you put in.

The good news is that you can’t lose more than your funded position. Polymarket doesn’t let you go into debt or owe more than you deposited.

Polymarket US doesn’t currently offer account-level deposit limits or loss limits. That makes risk management your responsibility from the start.

Watch for common warning signs. If you’re chasing losses, raising position sizes after a bad run, or trading markets you don’t understand just to stay active, it’s time to step away.

Tax documents are available through the Settings screen, which is worth checking before year-end. Profits from prediction market trading on a CFTC-regulated platform are generally taxable income in the US, and Polymarket doesn’t withhold taxes automatically.

WSN supports safer trading habits. Set a budget before you deposit, and treat that number as your limit, not a target you need to reach.

How We Rate Prediction Markets

We don’t score prediction market apps based on screenshots, press releases, or a five-minute tour of the home screen. Each platform gets tested with money deposited, positions placed, and enough time inside the app to see where it works and where it gets annoying. 

For the Polymarket app review, we deposited $1,000 via debit card and traded across NBA game winners, MLB player stats and positions, NBA futures, and politics markets over three weeks. We tested limit order execution, checked order book depth at multiple price levels, and verified withdrawal speed by initiating a bank transfer on a Tuesday and logging its clearing time.

Customer support is tested with non-trivial questions about contract settlement rules, KYC edge cases, and order-handling behavior. We measure response time and technical accuracy, not whether the team is friendly.

The final score is broken down by user experience, markets, bonuses, banking, and customer support. We don't weigh them equally because traders don't experience them in the same way. Some categories show up every single trade. Others you only notice when something goes wrong.

Why You Should Trust Us

Prediction markets were generating real trading volume among serious players years before anyone outside the space noticed. We were there early, which means we've watched this space go from a niche corner of crypto to a federally regulated product backed by some of the biggest names in finance. That context matters when you're evaluating a platform like Polymarket, because the story of how it got here is as important as where it is now.

We've made money on these platforms and lost money on these platforms. We've had withdrawals that cleared in hours and withdrawals that took four days longer than the FAQ said they would. We've opened support tickets that were resolved within minutes and others that got lost in a queue. When something shows up in a review on this site, it's because someone on our team experienced it firsthand, not because a PR team sent over talking points.

Prediction markets are still new enough that the difference between a good platform and a bad one isn't obvious from the outside. Our job is to make that difference visible before you deposit, not after.
