Prediction Market Sites Like Polymarket for October 2026

An Overview of Polymarket

Polymarket is an exchange site where traders can purchase contracts based on real outcomes. There are always two options for these contracts, either Yes or No. During our Polymarket review, we found that you can make predictions across a whole range of topics like sports, crypto, world events, tech, and more. Some exchange sites have a lot of options, whereas Polymarket does seem to have less choice. This is partly because it was unavailable in the US until quite recently, but more and more topics are being added each month.

Polymarket is also a crypto prediction market which means that you can use cryptocurrencies to trade contracts. Sports predictions are often the most popular, which is no surprise given there's a wide range of different sports available to trade at Polymarket. So as you can see there are some positives to Polymarket, but the limited options could have you looking for alternative sites.

How Prediction Markets Work

Prediction markets are exchange platforms where you can trade on the outcomes of real world events. With these sites you can buy and sell contracts which are tied to specific questions. The questions will vary depending on the area that you’re making the contract in. The questions could be:

• Will Bitcoin reach $100,000 by the end of the year?
• Will Manchester City win the Premier League?

Each contract only has two possible outcomes which are either Yes or No. If you think the event will happen then you choose Yes, and if you think it won’t, then you choose No.

How Contract Pricing Works

The price for a prediction will range from $0.01 to $0.99, which reflects how likely other users believe the outcome to be. So the higher the price, the higher the probability that the outcome will be true (according to other users). The prices will change consistently depending on how other users are making predictions. It’s entirely up to you whether you choose to trade the Yes or No contract, the prices are simply there to guide you. The price of the contract will then determine the payout that you receive if you predict the correct outcome.

Top Apps Like Polymarket

If you’re looking to try out a new app that’s similar to Polymarket but offers some different features, here are our recommendations. You can use any of these platforms to make trades on contracts for a variety of topics, but some do focus on specific areas.

Kalshi: Great for Beginner Traders

Kalshi: Pros & Cons

• Fully CFTC-regulated exchange
• Diverse markets including sports, politics, and economics
• Supports PayPal, Venmo, and Crypto deposits
• Highly rated mobile app for iOS and Android

• Trading fees apply to both makers and takers
• Bank withdrawals can take several business days

Kalshi is our first site like Polymarket where you can make predictions based on Yes or No outcomes of specific events. It’s a fairly popular site, mostly because it’s got a very broad range of areas available for trades. We’d say it has a larger variety than Polymarket does, so it’s a great option for anyone who likes to trade on more niche topics.

No matter where you’re based in the US, you can sign up to Kalshi. If you enjoy the social features that come along with trading, then you’ll likely enjoy the rolling chat that this platform has too. You can also pick up a sign up offer too, simply trade $10 and receive a $10 bonus credit.

Crypto.com: Try the Mobile App

Crypto.com: Pros & Cons

• Competition-based promotions
• iOS & Android apps
• Minimalist website design
• Beginner-friendly

• No email support

There is plenty of variety to be found at Crypto.com which you guessed it, is a crypto-focused platform. Although it also offers contracts across various other categories like sport, culture, and politics.

One highlight of Crypto.com is its fantastic mobile app. Using this allows you to make your trades on the go, with just a few taps. We enjoyed the app when we tried it out and it tends to get very consistent positive ratings, indicating that other traders enjoy it too.

Despite it being a crypto-focused platform, you can also use other payment options if you’d prefer. You can even grab a $20 bonus to kick start your trades when you sign up through our links.

OG: A New Prediction Market

OG: Pros and Cons

• Secure and regulated by the CFTC
• No user limiting on trades
• Wide range of market categories
• Welcome bonus for new traders

• Sports contracts are restricted in some states

We think it’s good to include both new and more established sites in our recommendations. OG is a newer platform, and it’s quickly gaining traction with traders. OG offers downloadable apps for both iOS and Android, and the platform is also fully optimized for mobile browsers, so you can load it up in any browser too.

OG also has a few different ways of rewarding new users with up to $100 in bonuses up for grabs. You can pick up these bonuses by completing a number of tasks after signing up. This includes verifying your email address and phone number, completing the KYC verification process, making your first deposit and placing your first trade.

Robinhood: Now Offering Prediction Markets

Robinhood: Pros and Cons

• Fully regulated via CFTC oversight
• Integrated into the main Robinhood app
• 4 billion+ contracts traded within its first year

• Event contracts blocked in Maryland, sports contracts blocked in Nevada

Robinhood is a well established app that’s used for trading crypto, stocks and such. However, the platform has recently expanded into the world of prediction market sites, hence why it’s made this list. Some examples of predictions you can make include major sports leagues, politics, economics and cultural events.

The topics within these areas can vary hugely, anything from “How many weeks will Taylor Swift stay at #1?” to “What team will win the English Premier League?.” You can pick up a welcome bonus too which will be a mystery stock worth anywhere between $5 and $200. All you need to do is sign up and make an initial qualifying trade– simple!

Underdog: A Sports Focused Prediction Market

Underdog: Pros and Cons

• Available in 38 states + DC
• Wide range of prediction markets
• Awesome mobile app
• Quality customer support

• No welcome offer

At Underdog, you can make predictions across two major topics: sports and economics. So if you’re looking to purchase trades in these areas, then this could be the platform for you. You could trade event contracts in major leagues like the NFL, MLB, NHL and NBA. When it comes to economic predictions, this site focuses on business and trade-related contracts.

The one area that Underdog is lacking is promotional offers for users. However, this could be an area where the site improves over time. The app is very easy to use and even has multiple options for the colour scheme, so you can adjust according to your preferences.

Trading derivatives involves risk and may not be appropriate for all. For more information visit: https://www.nadex.com/rules and https://underdogfantasy.com/rules. For Crypto.com Predictions, the term "pick" refers to a product traded on CDNA.

Which Site Like Polymarket Should You Choose?

Now that we’ve talked a little bit about our recommended Polymarket sister sites, let’s discuss how they compare to each other. Four out of five of our alternative platforms offer some form of welcome bonus. For the most part, this includes a bonus credit after making an initial trade.

Kalshi probably has the most variety of any site like Polymarket, with a huge range of topics available to trade contracts on. So if this is important to you, then Kalshi may be your best choice. If you enjoy sports prediction markets, we recommend Underdog or OG, as they both focus on this.

Crypto.com is an obvious choice for trading on crypto-based contracts, although Kalshi also offers this. Other things to consider are the available payment methods for making deposits. If you have a strong preference over one, then it’s worth checking to see which sites offer this before making a decision.
