What Is the Polymarket $25 Bonus?

Who Is Eligible for the Polymarket Promo Code?

New players must meet each criterion below to activate their Polymarket code:

Is Polymarket Legally Operating in the US?

Polymarket US operates through QCX LLC, a CFTC-designated contract market. The platform returned to the US market in 2025 after acquiring the exchange’s federal designation, and it continues to operate under that same regulatory framework today.

In July 2026, a federal judge issued a preliminary injunction blocking Minnesota from enforcing a new law that would have banned prediction markets starting August 1. Polymarket and Kalshi can continue operating in the state while the case moves through court.

State challenges have picked up since then. On Sept. 25, the Sixth Circuit ruled that Ohio and Tennessee can apply their gambling laws to Kalshi’s sports event contracts, and on Oct. 2 the Ohio Casino Control Commission sent cease-and-desist letters to Polymarket and nine other platforms.

Polymarket US sued Ohio officials in federal court on Oct. 16, arguing that federal commodities law overrides the state’s gambling rules and that Ohio’s licensing requirements violate the Commerce Clause. Ohio’s governor has said the state will act against operators that keep offering sports contracts, and Ohio is one of the states excluded from the GRINDERS offer.

Other suits are pending. On Sept. 24, New York sued Polymarket, arguing that it operates without the required state license. On Oct. 21, Baltimore sued Kalshi and Polymarket, becoming the first U.S. city to sue prediction market platforms directly. Baltimore is in Maryland, which is one of the states excluded from the GRINDERS offer as well.

The fight is headed toward the Supreme Court. On Oct. 7, 39 states and D.C. urged the justices to take up a New Jersey case involving Kalshi. The Court granted Kalshi a 28-day extension on Oct. 30, so its response is now due Dec. 7. Status as of Nov. 2, 2026.

What Do Polymarket App Reviews Say?

The star ratings are not close this time, with iPhone users at 4.6 out of 5 and Android users at 3.8, and they complain about different things.

When we checked the stores on October 26, 2026, Polymarket had a 4.6 out of 5 rating from about 63,000 reviews on the Apple App Store. On Google Play, it was noticeably lower at 3.8 out of 5 from roughly 14,000 reviews.

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 also 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.

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, Apple Pay and wire transfer 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:

1. Open your profile in the Polymarket US app.
2. Select “Deposit.”
3. Choose one of the funding methods available to your account.
4. 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 GRINDERS and depositing real money.

What to Trade Your $25 Credits With: My Polymarket Picks for this Week

Picks, prices and combo by Stephen Pierce, as of Monday, Nov. 2.

Once the credit lands in your account, you can use it as collateral on eligible markets in the Polymarket US app, including sports.

Here are my four Polymarket picks for Saturday and Sunday, with kickoff times, channels and the prices I saw on Monday, Nov. 2.

• 🏈 BYU vs. Utah (Saturday): This is a huge Big 12 matchup, with two top-10 teams fighting for College Football Playoff berths. BYU is the road underdog at Rice-Eccles Stadium, and I have the Cougars winning a tight game at 36¢ in the noon ET kickoff on ABC. At that price the risk is plain, since a BYU contract at 36¢ loses the full 36¢ if Utah wins at home.
• 🏈 Alabama vs. LSU (Saturday): This is another great matchup, with two SEC powerhouses that both have the playoff on their minds. I think LSU has the better offense this season, and I expect the Tigers to win a surprisingly high-scoring game at home at 67¢. Kickoff is at 3:30 p.m. ET on ABC. At 67¢ the price is steep, and an Alabama win would cost most of the position.
• 🏈 Miami vs. Notre Dame (Saturday): I think Notre Dame is overrated this season, and Miami looks a little better. Miami is not in the toughest conference, but I think the Hurricanes get the edge and win a close game in South Bend at 35¢. Kickoff is at 7:30 p.m. ET on NBC and Peacock. The market gives Miami a 35% chance, so a Hurricanes contract at 35¢ carries real risk.
• 🏈 Packers vs. Patriots (Sunday): This is one of the best games to watch this weekend, and both teams have looked great over the last month. I think New England’s young quarterback throws too many interceptions, and I have the Packers stealing this one on the road at 42.5¢. Kickoff is at 4:25 p.m. ET on FOX from Gillette Stadium, with Tom Brady on the call. Green Bay is the road team, so a Packers contract at 42.5¢ carries real risk.

At these prices, and before fees, $10 buys about 28 BYU contracts at 36¢, about 15 LSU contracts at 67¢, about 29 Miami contracts at 35¢ or about 24 Packers contracts at 42.5¢. Each contract pays $1 if the pick wins, so the same $10 would return about $28, $15, $29 or $24 on a win, and a losing contract pays $0

Beyond these four picks, sports markets can cover game winners, totals, player stats, tournament advancement, conference champions, and season-long futures.

Non-Sports Markets on Polymarket Right Now

It’s not just sports; you’ll also find markets on politics, finance, tech, crypto, culture, weather, and plenty of other real-world events, though what’s listed changes over time.

_{These markets are subject to change according to volume and number of trades. Last verified: November 6, 2026}

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, as this week’s picks table shows. Miami at 35% means traders give the Hurricanes roughly a one-in-three chance, while LSU at 67% is the home favorite, and both numbers can move as injury reports and lineup news come in.

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.

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.

Polymarket Pros and Cons

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.

Polymarket Promo Codes FAQs

What is the Polymarket promo code and referral code?

The Polymarket promo code GRINDERS is the code new users enter in the promo or referral code field during Polymarket US signup. Enter it at registration and deposit at least $10 to get the $25 trading credit.

It’s one credit per person, and you must enter it before the deposit. Polymarket also runs a separate Refer-A-Friend program, where your referral code is your own username once your account is active.

Can I withdraw the $25 Polymarket bonus directly?

No. The credit isn’t withdrawable cash. You must trade an amount equal to the $25 credit before any resulting profits become withdrawable, and if a trade made with the credit loses, the credit used on that trade is gone.

Does the $25 Polymarket bonus expire?

Yes. The $25 credit expires 30 days after it is added to your account, so any unused credit is lost after that.

Is Polymarket legal in the US?

Polymarket US operates through QCX LLC, a CFTC-designated contract market, and is available in over 40 states. Some states are challenging prediction markets in court, including Ohio, where Polymarket US sued state officials on Oct. 16, and New York, which sued Polymarket on Sept. 24, so availability can change. The GRINDERS offer is not available in AZ, IL, MA, MD, MI, MT, NV, OH, and WA.

Does Polymarket have sports betting?

Not exactly. Polymarket US offers sports event contracts, not traditional sportsbook bets. These can include game winners, totals, player stats, and futures.

For standard sportsbook betting, check out our guide to the Top 11 Best Mobile Sports Betting Apps.

Does Polymarket charge fees?

Yes. You pay a fee when you take an order. If you place a maker order, you may earn a rebate. Unfilled orders aren’t charged.

How long do Polymarket deposits take?

Debit cards are usually instant. ACH transfers take 1-3 business days, depending on your bank and verification.

Is Kalshi better than Polymarket?

It depends. Kalshi offers more ways to fund your account, while Polymarket can be better for maker rebates and limit-order trading. The better platform is usually the one with the best prices and liquidity for the specific market you want.

What if my $25 Polymarket bonus credit doesn’t show up?

Check that your deposit has fully cleared — the credit is added after the qualifying $10 deposit is confirmed, which can take longer for ACH transfers than for debit card or Apple Pay. If the deposit has cleared and the credit still isn’t showing after 24 hours, contact Polymarket US support through in-app chat or support@polymarket.us with your account email and the deposit date.

How long does KYC verification take for the Polymarket promo code?

KYC is usually quick — most users complete it in a few minutes during signup. Delays can happen if the information submitted doesn’t match your ID, or during periods of high signup volume. If verification is still pending after 24 hours, reach out to Polymarket support directly, since the promo code credit can’t be applied until KYC is complete.

Can existing Polymarket users redeem the GRINDERS promo code?

No. The code must be entered during new-account registration — it cannot be added to an account after signup. Existing users aren’t eligible for this specific offer, though Polymarket’s separate Refer-A-Friend program may offer other incentives for current account holders.
