We’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. We’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.
Underdog Predict follows the same "Yes"/"No" contract format used across top prediction markets, allowing users to trade on sports and cultural outcomes at market-clearing prices. Rather than functioning simply as a retail broker routing all volume to third-party venues, Underdog operates its own in-house, federally regulated exchange: Underdog Exchange (UDX).
Contracts trade on a scale from $0.01 to $0.99, reflecting the crowd-sourced probability of an event occurring. A contract trading at $0.77 implies a 77% consensus probability. A winning "Yes" contract resolves at $1.00, yielding a $0.23 profit per contract (minus applicable trading fees). An incorrect outcome settles at $0.00, meaning your downside is strictly capped at the initial purchase price.
Underdog Predict operates across four integrated layers:
Underdog originally launched prediction markets through a partnership with Crypto.com | Derivatives North America (CDNA), but in March 2026 it acquired Aristotle Exchange and, as of July 2026, now operates its own in-house, federally regulated exchange, self-certifying specific sports event contracts natively while continuing to list other contracts through CDNA.
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, plus college football, college basketball, and other sports like soccer and tennis get a good look-in too. Underdog has stated it plans to keep expanding its market coverage over time, so expect more sports to be added down the line.
What's impressive is the sheer range of sports prediction markets on offer. 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 while you can easily jump between products on the app, your prediction market contracts are traded on a standalone exchange slip completely separate from your traditional fantasy pick entries. Definitely a sleek and unique setup that keeps your trading portfolio clean and organized.
Unlike traditional sportsbooks that hide their cost in a 4.76% juice on standard -110 lines, Underdog Predict utilizes an exchange-based pricing model with two transparent fee components:
Underdog uniquely groups all of its non-sports event contracts under a dedicated "Culture Markets" tab. This centralized interface allows you to trade on shifting real-world probabilities spanning political outcomes, macroeconomic indicators, tech developments, and pop-culture trends.
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. We 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.

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:
This is where you can get bonus entries 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 as bonus entries. However, you should note that these can't be withdrawn as cash.
We'd say that the Underdog app is just as good as the one found in our Fanatics prediction markets review and that’s saying something.
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.
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.
A major trust signal for us is Underdog's regulatory backing. The brand launched prediction markets in 2025 through a partnership with Crypto.com | Derivatives North America (CDNA), a Designated Contract Market (DCM) and Derivatives Clearing Organization (DCO) fully registered with the Commodity Futures Trading Commission (CFTC).
Since then, Underdog has gone further, acquiring Aristotle Exchange in March 2026 to build its own in-house CFTC-regulated exchange, and has now self-certified its own sports event contracts. This gives Underdog a level of institutional security and regulatory oversight rarely seen in the prediction market space.
Underdog’s Prediction Picks are available only when you are physically located in an eligible state and are at least 18 years old. State availability can change, so check Underdog’s current Prediction Picks eligibility list before signing up or placing a trade, rather than relying on an older state count.
Don’t assume that access to Underdog’s fantasy contests tells you whether you can trade Prediction Picks, as they’re separate products with different availability. In September 2026, Underdog stopped offering new fantasy contests in seven states, but said Prediction Picks would remain available in several of them. Check the product shown in the app for your location before adding funds.
In July 2026, Underdog agreed to be acquired by IG Group, a UK-based, FTSE 100 financial technology company that also owns trading platforms like tastytrade, in a deal worth up to $1.3 billion. The agreement includes roughly $1.1 billion upfront (a mix of IG shares and cash) plus a $200 million earnout tied to 2026 performance, with IG also assuming around $160 million of Underdog's existing debt.
The deal is still pending regulatory and antitrust approval, with a close expected in late 2026 or early 2027. In the meantime, Underdog continues operating under its own brand with its existing leadership team, so nothing changes for traders today, but it's worth knowing that a major, publicly listed financial firm is set to become Underdog's parent company, which should only add to the institutional backing behind its prediction markets.
We were pleased to find that Underdog employs bank-grade security protocols to ensure the integrity of every trade, including:
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:
It’s worth noting that, while Underdog lets you use a wide range of payment methods for making deposits for its other services, official Prediction Picks funding options currently include debit and credit cards (including Apple Pay) and Trustly bank transfers.
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.
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.
During our Underdog review, we found that navigating the Underdog Help Center is highly straightforward and backed by an accessible 24/7 customer care team. Below, we’ve outlined the different support channels available to its users.
