I’ve written this Underdog prediction markets review to tell you all you need to know about this brand new service. Perfect for seeing what the hype is all about.
Here you’ll learn how Underdog operates to let you enjoy trading prediction markets for sports, culture, politics, economics and beyond. I’ll highlight the brand’s legality and security before touching on fun things like promo offers, mobile apps and much more. All you need to see if Underdog is right for your prediction markets needs.
A Crash-Course in Prediction Markets
While plenty of sports fans are used to traditional betting lines, prediction markets work a bit differently. Instead of locking in static sportsbook odds, you are participating in a live, player-driven financial exchange. On the Underdog Predict platform, the crowd's collective trading activity creates a shifting percentage chance for real-world outcomes, allowing you to buy and sell sports event contracts just like shares on a stock market.
At Underdog, every single trade is simplified into a straightforward, binary "Yes" or "No" choice. For example, you might buy a "Yes" contract stating that the 49ers will win their next game, or a "No" contract predicting they’ll lose.
The price of each individual contract scales directly between $0.01 and $0.99, perfectly mirroring the market’s implied probability. If the 49ers are heavy favorites with a 77% implied chance of winning, a "Yes" contract will cost you $0.77. If they pull off the win, your contract automatically matures to a full dollar ($1.00), leaving you with a $0.23 profit per share.
On the flip side, if you back a massive underdog with a low 23% chance of winning, your contract only costs $0.23 to buy, but hitting that correct prediction nets you a much larger $0.77 profit per share. Best of all, you don't have to worry about separate exchange trading fees cutting into your margins, as all operational transaction costs are built straight into the contract prices.
Many Kinds of Prediction Markets in This Underdog Review

The best picks at Underdog
![Underdog Predictions]()
Predict your favorite sports at Underdog
Underdog may be better known for its fantasy sports and even regular sportsbook services, but it has recently made the brave move into the prediction markets realm. This was launched in September 2025 in conjunction with Crypto.com and here are the main kinds of prediction markets featured at Underdog:
Sports Prediction Markets
The bulk of the prediction markets at Underdog are devoted to sports which isn't surprising considering the brand's background. You'll find in-depth coverage of the NFL, NBA, NHL and MLB here, and other sports like soccer and tennis get a good look-in too. Underdog has also been expanding its markets to include everything from the Olympics to fighting, motor sports and golf.
What's impressive is the sheer range of prediction pick markets on offers. As well as picks for things like the game winner, spread and total points, you might be able to find player prediction picks for things like rushing yards, passing yards, receiving yards, anytime touchdown and so on. Just note that the availability of such markets will be determined by the state that you are trading from.
It's also worth noting that you can make combo entries when you trade a predictions market contract and two or more fantasy picks. Definitely not the kind of thing that you see at too many prediction markets sites.
You can also get Exclusive Prediction Picks which are unique prediction markets that tend to become available for the biggest sporting encounters. For example, the recent Super Bowl between the Seahawks and Patriots had exclusive prediction picks for things like Big Game MVP, will there be a safety, and even the total number of fourth down conversions.
Politics Prediction Markets
Given the current ferocious political climate, it's little surprise that Underdog would make political prediction markets a key part of its appeal. This means that you can make your predictions on all of the big political questions of the moment, such as who will be the US presidential election winner in 2028, and who will be the next Democratic presidential nominee.
Things also go down to state-level politics where you can make predictions on things like who will be the Maine Democratic Senate primary winner and who will be the next governor of California. Some of the political markets might not be as 'spicy' as you get with some rival brands, but most of the major options should be available here.
Economics Predictions Markets
Underdog also lets you make your predictions on a range of economics markets. This means that you can trade contracts on things like whether there will be a US recession by the end of the year, what the Fed's decision will be at the end of the month, and even things like the unemployment rate and jobs added in a particular month.
I noticed that Underdog has a real focus on AI developments and it frequently features markets for things like the best AI model, OpenAI IPO date and so on. There are all of the usual other markets so that you can make your predictions on the largest company at the end of the year.
There's also a limited range of financials available such as what the Gold Index Value will be at a particular time, but perhaps not as much choice as you get at other prediction markets sites. Still, there's enough here for most newbies and casual traders.
Culture Prediction Markets
I found a decent range of culture prediction markets at Underdog, although they tend to be focused upon specific awards ceremonies. It was Oscars season at the time of my writing this Underdog prediction markets review and so you were able to trade contracts on things like best picture winner, best supporting actor winner and even best film editing winner.
You should expect to find a similar choice for things like the Grammys where you can make your predictions on the album of the year, best new artist and so on. Again, there might not be some of the weirder cultural prediction markets that you get at some rival sites, but Underdog covers most bases.
Climate Prediction Markets
At the time of writing this Underdog prediction markets review, the brand only had one climate market open. This allowed you to make trades on whether the current year will be the hottest on record. Interestingly, you could pick the ranking so that it could be in first place, second place and so on down to sixth place and beyond. Good for getting a little extra flexibility in your climate trades.
Crypto Prediction Markets
I was a little bit underwhelmed by the fact that there weren’t any crypto event contracts available at the time of writing this Underdog prediction markets review. This is fairly unusual considering that the brand has teamed up with Crypto.com to create the whole Prediction Picks service.
I’m guessing that it’s just a temporary blip as few things get people talking as much as cryptocurrencies. So check back here to see when you can make predictions about when the Bitcoin bubble will burst and so on.

Is There a Underdog Prediction Markets Welcome Offer?
Lots of prediction markets sites will tend to omit welcome offers for new customers. This is the case at Underdog as the brand doesn’t currently have any kind of sign up bonus that you can use for prediction markets. I will, of course, update this guide if and when such a deal becomes available. But for now, you will have to fund your trading purely with your own cash.
Others Deals Found in My Underdog Prediction Markets Review
Prediction markets brands don’t typically offer the same range of promos for existing customers as their sportsbook counterparts. While this is certainly true of Underdog, the brand does have a few deals that could keep things interesting. Here are just a few examples, but be sure to check the terms and conditions of each deal to ensure that it can be used for prediction markets:
Referral Deals
This is where you can get bonus credit from Underdog by bringing a friend to the site for the first time. How it works is that you have to get your unique referral code from Underdog and then send it to a friend.
From here, your friend has to download the Underdog app, register their first account while entering your referral code and username in the relevant box. Once they have gone on to deposit a minimum of $10, you will receive your rewards.
This deal acts as a kind of 'guarantee' for if you don't like what you find at Underdog. It's a promo that will offer you a refund of up to $100 but it can only be claimed within 48 hours of making your first trade.
Big Reasons to Download the Underdog App
I’d say that the Underdog app is just as good as the one found in my
Fanatics prediction markets review
and that’s saying something. What I like most about the app from Underdog is that it combines everything from its regular sportsbook and fantasy sports service to the new prediction markets option.
The Underdog app is available for all modern iOS and Android devices and is downloadable from the App Store and Google Play. Upon downloading the app, you'll find it simple to sign up or login, and then it's effortless to swipe through all of the many different prediction markets, and executing your trades is as simple as tapping your mobile screen.
All other tasks such as making deposits, contacting customer support and putting in withdrawal requests can be carried out easily from within the app. So while the Underdog website offers you a reasonable straightforward way to trade from your browser, the brand's app makes it way more convenient.

Is Underdog Prediction Markets Safe?
During our review of the platform, we quickly realized that safety and regulatory compliance are the cornerstones of the Underdog ecosystem. Unlike traditional sportsbooks that operate under state-by-base gaming licenses, Underdog’s prediction market integration represents a shift toward federally overseen financial derivatives. Below we take a closer look at what we discovered as we tested this platform for ourselves.
The Underdog & Crypto.com (CDNA) Partnership
A major trust signal for us is Underdog’s 2026 partnership with Crypto.com | Derivatives North America (CDNA). CDNA is a Designated Contract Market (DCM) and Derivatives Clearing Organization (DCO), fully registered with the Commodity Futures Trading Commission (CFTC). This partnership allows Underdog to offer sports event contracts that are federally regulated, providing a level of institutional security rarely seen in the prediction market space.
Legality: Where Can You Trade on Underdog?
Because Underdog’s Prediction Picks are classified as event contracts rather than sports wagers, they operate under the U.S. Commodity Exchange Act. This allows the platform to exist in many states where traditional sportsbooks are restricted.
Underdog Prediction Picks are available to residents aged 18+ in most U.S. states. However, due to the evolving legal landscape and state-level challenges regarding "sports-themed" derivatives, the platform is currently unavailable in: AZ, CO, DE, IL, KY, MD, MA, MI, MS, NV, NJ, NY, OH, PA, and TN.
How Underdog Protects Your Data & Capital
We were pleased to find that Underdog employs bank-grade security protocols to ensure the integrity of every trade, including:
- Encryption:
The app and site use 256-bit SSL encryption to protect personal data and financial transactions.
- Segregated Funds:
In alignment with CFTC standards, user funds are held in segregated accounts, ensuring they are protected and available for withdrawal at all times.
- Privacy Compliance:
Underdog maintains a transparent privacy policy that adheres to modern data protection standards, ensuring your information is never sold to third-party marketers.
Responsible Trading: Tools for Success
Underdog treats prediction markets with the same rigor as financial trading. We found that the platform provides a robust suite of Responsible Trading tools to help you manage your risk:
- Deposit Limits:
Set daily, weekly, or monthly caps on how much capital you can move into the exchange.
- Cooling-Off Periods:
Take a voluntary break from the platform ranging from 3 days to 9 months.
- Self-Exclusion:
For long-term protection, users can opt for a permanent self-exclusion of 1 year to a lifetime.
Funding Your Prediction Markets Trades
It’s worth noting that, while Underdog lets you use a wide range of payment methods for making deposits for its other services, only debit cards that include Apple Pay as well as Trustly bank transfers can be used for your prediction markets trading.
The good news is that you can add funds to your account from a respectable minimum of $10 at a time, and that the deposits should go through instantly and without charge. Perfect for getting straight into the prediction markets trading action.
Speedy Withdrawals Found in This Underdog Prediction Markets Review
Once your markets have settled or you’ve executed your trade early, you will be ready to make a withdrawal of your returns. Note that the minimum withdrawal is $10 but you shouldn’t ever be hit with any processing  Underdog prediction market fees .
You’ll usually be expected to make a withdrawal back to the same payment method used for your deposits, and it’ll rarely take longer than three working days for the funds to come back into your account.
Getting Help at Underdog
While it’s easy enough to use the Underdog prediction markets service, it’s also good to find that you can get in touch with the brand’s customer care team 24/7. The simplest way to get in touch is to use the live chat service but there is also email support that should give you a speedy response.
Just remember to check the FAQ section on the Underdog site as this has a wealth of detailed information about all aspects of the brand’s services. For example, there is a specific section devoted to Prediction Picks that is well worth a closer look.
