Underdog Prediction Markets Review for August: Is Underdog Legit?

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.

A Crash-Course in Prediction Markets

Underdog Predict follows the same "Yes"/"No" contract format used across top prediction markets, but with contracts now settling natively through Underdog's own UDX exchange for sports events, rather than routing everything through a third-party venue.

In practice, that means a contract priced at $0.77 still implies a 77% chance of that outcome, with a correct "Yes" pick netting you a $0.23 profit per share (minus a small per-contract exchange fee) once it matures to a full dollar. Get it wrong, and you lose only what you paid for the contract.

What's different at Underdog is that sports contracts filed through UDX carry Underdog's own CFTC self-certification, while non-sports markets continue to run through its Crypto.com | Derivatives North America partnership, a split worth knowing since it shapes which contracts show up where in the app.

The best picks at Underdog

Predict your favorite sports at Underdog

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.

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, 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.

Culture Markets (Politics, Economics, Crypto, and More)

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.

• Politics Prediction Markets: Given the fast-moving political climate, Underdog features high-profile, near-term political questions. You can buy and sell binary contracts on major upcoming national election benchmarks, key administrative appointments, or the next official party nominees. Things also go down to state-level politics where you can make predictions on prominent regional races. Most of the major options should be available here.
• Economic Prediction Markets: Underdog also lets you trade a range of economic prediction markets. This means you can trade contracts on things like whether there will be a US recession by the end of the year, what the Fed's interest rate decision will be at the end of the month, and even things like the national unemployment rate or jobs added. The platform heavily highlights tech development trends, featuring liquid contract categories tracking major AI model rankings and corporate tech timelines. There's also a select choice of financials available, such as tracking gold or commodity index trends.
• Culture Prediction Markets: We found a decent range of entertainment contract options at Underdog, which tend to focus on specific awards ceremonies. During major entertainment seasons, you can trade contracts on high-profile entertainment events like the Oscars or Grammys, buying "Yes" or "No" positions on categories like Best Picture, Album of the Year, or Best New Artist.
• Climate Prediction Markets: Underdog's climate prediction contracts allow you to make trades on whether the current year will hit specific meteorological milestones. Interestingly, you can pick the specific global temperature ranking, choosing whether the year will finish in first place, second place, or beyond, giving you great flexibility in your environmental trades.
• Crypto Prediction Markets: Leveraging its partnership with Crypto.com’s U.S. derivatives arm, Underdog lists highly competitive cryptocurrency event contracts. Instead of being left out, traders can browse active contract tracks relating to major digital asset movements, such as whether Bitcoin or Ethereum will reach specific milestone values or clear key target ranges by a set date.

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. 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.

Others Deals Found in Our 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 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.

Big Reasons to Download the Underdog App

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.
