What Is the Polymarket $25 Bonus?
| What the $25 Represents | It is a promotional trading credit awarded to first-time account holders. It provides extra capital to trade prediction markets alongside your initial deposit. |
| $10 Qualifying Deposit | To trigger the bonus, you must complete account registration using a valid promo code and make a minimum initial deposit of $10 into your account. |
| Which Funds Get Used First | Your deposited cash is always spent first. The $25 credit only starts covering a position once you’ve used your own balance. Polymarket’s incentive terms describe the same order: existing collateral is used before the credit. |
| Trading-Credit Mechanics | The credit is applied once Polymarket confirms your $10 deposit meets the campaign requirements. You don’t have to place a trade to receive it. There’s no single-trade requirement either: you can spread the $25 across as many positions as you want, in any amount, and it can cover applicable trading fees. |
| Who Qualifies | The offer is available exclusively to new, first-time Polymarket users who complete the identity verification (KYC) process, are at least 18 years old, and reside in an eligible region. |
| Whether It Is Cash | No, the bonus is not cash. It holds no cash value on its own and cannot be transferred or withdrawn directly to a bank account. |
| Expiration | Polymarket has not attached an expiration date to this deposit credit as of September 2026. |
| What Happens After a Trade | A winning trade does not burn the credit. The credit you used on the position comes back to your credit balance, and anything you make above that amount is paid to your cash balance, where it can be withdrawn. If the position loses, the credit used on it is gone |
How Do You Deposit and Withdraw Money on Polymarket?
The main deposit methods in the Polymarket US app are debit card and ACH bank transfer. Its payment system also supports card and Apple Pay transactions, although the exact options shown can depend on the account.
Debit-card and Apple Pay deposits are listed as instant, while ACH transfers can take one to three business days. Verification checks, bank processing, and payment-provider reviews may affect the actual timing.
To deposit:
- Open your profile in the Polymarket US app.
- Select “Deposit.”
- Choose one of the funding methods available to your account.
- Enter the amount and confirm the transaction.
Withdrawal options show up in the account once the funds are eligible. Polymarket checks the available balance and any funding-source requirements before processing the request, so not every withdrawal method will necessarily appear for every user.

Does Polymarket Charge Fees?
Yes. Polymarket uses a maker-taker fee structure: taker orders (filling existing offers immediately) incur a small fee, while maker orders (placing offers for others to fill) add market liquidity and often earn rebates. Fees vary based on volume and contract price—peaking around $0.50 where uncertainty is highest, and dropping near $0 or $1.
Unfilled, canceled, or rejected orders incur no fees, and all costs are displayed upfront before trade confirmation.
Still, when you see repeated complaints about withdrawals, account holds, app stability, or slow support, it’s something to keep in mind before using the Polymarket promo code
Polymarket App Review & Comparison
That said, it’s worth taking individual reviews with a grain of salt. App store ratings are self-reported and can reflect anything from temporary bugs to account-specific verification checks or even outdated app versions.
The gap in the ratings themselves is only a tenth of a star. The difference shows up in the review content: iPhone users mostly flag account and support delays, while Android users report more technical issues and frustration with execution during volatile moments.
| Platform | Current rating | What users are saying lately |
|---|---|---|
| Apple App Store | 4.6 out of 5 (59,000 ratings) | Mostly positive overall, but some users mention issues like account verification delays, withdrawal problems, and slow customer support. |
| Google Play | 4.5 out of 5 (12,900 reviews) | Feedback is more mixed, including app glitches, pricing errors, login issues, and trouble selling during fast-moving markets. |

One thing to remember: Polymarket US and the international Polymarket site run separately, so a contract you see on one might not be on the other. Check the U.S. app before you decide where to spend the credit.
How Do Sports Markets Work at Polymarket?
Polymarket sports markets can cover game winners, totals, player statistics, tournament advancement, conference champions, and season-long futures.
Each contract trades between $0.01 and $0.99. A “Yes” contract priced at $0.55 suggests that traders are giving the outcome roughly a 55% chance, while the matching “No” side would be priced around $0.45.
Those prices can change whenever traders react to new information. The September 10 game in Melbourne is a clean example: the Rams flew in roughly 28 hours before kickoff while the 49ers arrived a week early, and San Francisco’s 27-7 win moved NFC West and conference futures in the same session.
Here’s how a payout could work. Say you buy 90 “Yes” contracts at $0.55:
- The position costs $49.50 before fees.
- If the market settles “Yes,” each contract pays $1.
- You receive $90, leaving a $40.50 gain before fees.
- If the market settles “No,” the contracts pay $0 and you lose the $49.50 spent.
You can also sell the contracts before the market settles, provided another trader is willing to buy them. And, depending on how the price has moved, you may receive more or less than you originally paid.
For another sports-focused option, see our DraftKings Prediction review.
How Should You Trade Sports Markets on Polymarket?
Before opening a position, check the market’s settlement rules. These determine how the contract is resolved and can vary by market. For example, some soccer markets use the score after 90 minutes, while others include extra time and penalties. Player markets may also have specific requirements, such as starting the game or meeting an official statistical threshold.
Next, check the spread and available liquidity. A wide spread can make it more expensive to enter or exit, while limited contracts at a given price can result in your order being filled at less favorable prices.
A limit order lets you set the maximum price you’ll pay or minimum price you’ll accept. However, the order may not fill if the market never reaches your price.
Finally, decide on an exit plan before trading. You can hold until settlement, sell if the price moves in your favor, or exit if the trade moves against you. Liquidity can decrease near the end of an event, making it harder to trade at your preferred price.
What Do Polymarket App Reviews Say?
The star ratings are close, but users complain about different things between iPhone and Android.
When we checked the stores on September 18, 2026, Polymarket had a 4.6 out of 5 rating from about 59,000 reviews on the Apple App Store. On Google Play, it was slightly lower at 4.5 out of 5 from roughly 12,900 reviews.

Kalshi vs. Polymarket: What Are the Key Differences?
Neither platform is strictly better than the other; it really depends on how you like to trade.
Kalshi is a bit more flexible when it comes to funding your account, which can make getting started easier. Polymarket, on the other hand, can be more appealing if you’re comfortable placing limit orders and letting the market come to you, especially with its current maker rebate setup.
| Category | Polymarket US | Kalshi |
|---|---|---|
| Federal regulation | Operates through QCX LLC, a CFTC-designated contract market doing business as Polymarket US | Operates through KalshiEX LLC, another CFTC-designated contract market |
| Funding methods | Debit card, ACH, and supported card or Apple Pay transactions | Debit card, ACH, Apple Pay, Google Pay, PayPal, Venmo, Cash App deposits, crypto, and wire transfers |
| Trading fees | Charges executed taker orders and rebates executed maker orders | Charges transaction fees based on expected contract earnings and may also charge maker fees in selected markets |
| Best fit | Traders who want the current Polymarket lineup or prefer using limit orders that sit on the book | Traders who care more about having easier ways to fund their account |

How Did Polymarket Return to the US?
Polymarket returned to the U.S. market in 2025 by acquiring QCEX, a company that owned a federally regulated exchange and clearinghouse.
That exchange, QCX LLC, is now operating under the name Polymarket US and is approved by the Commodity Futures Trading Commission (CFTC) as a Designated Contract Market.
QCEX, QCX, and Polymarket US are related names from the same corporate structure, but they refer to different parts of the business, meaning they don’t refer to exactly the same legal entity.

Earlier Polymarket History
In January 2022, Polymarket reached a settlement with the CFTC that included a $1.4 million civil penalty and a requirement to shut down markets that didn’t meet federal derivatives rules.
The regulator said Polymarket had been offering event-based binary markets without the proper approval to operate as a regulated exchange. Today, Polymarket US runs through QCX LLC, a separate entity that has since been designated as a federally regulated contract market.
