The SPIN Polymarket promo code rewards new users with a $25 trading bonus once you deposit at least $10. But it’s not the only way to get a trading bonus on the platform.
Polymarket also boasts a refer-a-friend program, which gives the referrer and the friend $25 each to use on the site once the friend signs up and deposits $10+. Users can refer up to 50 friends for a maximum bonus of $1,250.
Here’s a table outlining the differences between the sign-up promo code and the refer-a-friend bonus.
| Polymarket Promo Code | Polymarket refer-a-friend | |

| Bonus amount | $25 per referred friend ($1,250 max) | |

But with the NBA season just getting underway, a top option is making a prediction on the eventual NBA champion.
With long-term markets like this, prices will fluctuate on a daily basis based on the latest on-court action.
But as of writing, the Oklahoma City Thunder and San Antonio Spurs are the clear favorites. The Thunder and the Spurs, led by superstars Shai Gilgeous-Alexander and Victor Wembanyama, respectively, fought it out in a seven-game series in the Western Conference Finals last season.
The Spurs prevailed but ultimately lost 4-1 to the New York Knicks in the NBA Finals.
While the Knicks dominated the postseason to end a 53-year title drought, they aren’t the team in the East with the best per-contract price. That honor goes to the Philadelphia 76ers, who added LeBron James and Jaylen Brown in the offseason.
Here are the prices for the complete top five, as of October 22, 2026.
| NBA Champion at Polymarket | Buy Yes | Buy No |
|---|---|---|
| Oklahoma City Thunder | 24¢ | 77¢ |
| San Antonio Spurs | 23¢ | 78¢ |
| Philadelphia 76ers | 11¢ | 90¢ |
| New York Knicks | 10¢ | 91¢ |
| Boston Celtics | 7¢ | 94¢ |
Polymarket’s US app operates under the oversight of the Commodity Futures Trading Commission (CFTC) as a Designated Contract Market (DCM). However, access to the platform and individual markets depends on location and eligibility.
Polymarket halted operations in the US in 2022 after regulatory action by the CFTC. The company later acquired QCX LLC, which held a DCM licence, paving the way for its return to the US market.
Polymarket returned to the US in a limited capacity in 2025 before expanding access in 2026. Users should check the current state-specific restrictions before signing up or trading.
Since 26 October 2026, users located in Michigan, or whose identity verification (KYC) is tied to Michigan, can no longer trade on sports markets due to a court order. These users can still close existing sports positions and continue trading on non-sports markets. Other location-specific restrictions may also apply.
Polymarket isn’t the only prediction market that has a promo code that will reward new customers with a welcome bonus.

The Polymarket app is available for both iOS and Android users, and is actually the primary way to access the platform, considering the promo code requires you to download it.
During my testing of the Polymarket app, I was impressed by the overall performance and design layout. The app runs smoothly at all times, and I didn’t experience any significant technical issues that hurt the experience of other prediction market platforms.
Polymarket’s app is designed in an intuitive way, so you never feel lost. The home page gives easy access to a range of market categories with a horizontal scrolling menu, or you can use the handy search function, which also highlights popular markets.
Polymarket also highlights top events, such as the World Series, with dedicated hubs that have banners in the “New on Polymarket” section of the home page. I also liked having a “Live” section that you can jump to from the bottom tab. It’s dominated by sports markets, which are broken up into specific categories, with the total live markets highlighted in red.
The sports markets available in the app depend on your location and eligibility. Since 26 October 2026, users located in Michigan, or whose identity verification (KYC) is tied to Michigan, can no longer trade on sports markets, although they can still close existing sports positions and trade on non-sports markets.
Using Polymarket’s app gives players access to useful features. I found push notifications particularly helpful, alerting me to trending markets or big updates to my positions.
A new feature at Polymarket is “Squads,” which has its own section in the bottom menu tab. This is Polymarket’s in-house social feature where you can make group chats with your friends to discuss your latest contracts. Polymarket also recenty expands its crypto market with a significant addition, creating five-minute markets for cryptocurrencies like Bitcoin, Ethereum, Solana, and XRP. Previously, 15-minute markets were the shortest available.

Polymarket is currently offering a $25 trading bonus with a deposit of at least $10, which you can get with our promo code SPIN. But it isn’t the first offer that the prediction market has created for first-time users.
So if you’ve heard about a different Polymarket bonus and are confused about where to access it, let’s run you through some previous offers.
Let’s recap everything we’ve gone over so far. The Polymarket promo code SPIN gives new users a $25 trading bonus with a deposit of at least $10. The platform doesn’t require users to complete a trade with their $10+ deposit, so you can get access to your bonus as soon as you finish signing up and fund your account.
Polymarket’s promo code does require downloading the app to use the promo code, but as I went over in my app overview, it’s the standout option to use the platform anyway.
To claim the Polymarket trading bonus, click through one of our banners and complete the sign-up process, subject to the offer’s terms and eligibility requirements. Before depositing, check which markets are available in your location. In particular, users located in Michigan, or whose identity verification (KYC) is tied to Michigan, cannot trade on sports markets as of 26 October 2026, but can still close existing sports positions and continue trading on non-sports markets. This page is updated regularly, so check back for the latest information on Polymarket promo codes.
