Underdog Predictions Prediction Markets Review 2026: Platform Overview

https://www.strafe.com/esports-betting/reviews/underdog-predicts/

What is the Underdog Predictions platform?

Before we jump into my main review, I wanted to take a moment to talk about the platform and the legality of the platform. Underdog is a well-known DFS platform that has recently introduced prediction markets, which is where users buy binary event contracts based on their predicted outcome for an event. These events cover the spectrum, including sports, economics, crypto pricing, weather, cultural predictions and more. Underdog has partnered with Crypto.com and Kalshi to offer these event contracts.

How do Underdog Predictions work?

The idea behind these predictions is that users need to make a binary choice, such as Yes/No, Higher/Lower, Team A/ Team B, and so on.

For example, will the Seahawks win their game? Yes or no. Will the Dallas Cowboys score first? Yes or no. Who will win an upcoming game: the Lakers or Celtics? And so on.

A simple example is whether a specific team will win their next game, and you can buy an event contract based on your prediction (e.g., Celtics or Lakers). Contracts range from 1 cent to 99 cents, and prices shift as traders start taking positions in one direction or another. You can roughly think of the price of the contract as the “group wisdom” as to whether an event will occur. For example, if the price to purchase a “Celtics win” contract is 68 cents, then the group wisdom is predicting a roughly 68% chance that the Celtics will win.

When the event is done, the contract automatically settles at $0 for incorrect predictions, or $1 for correct predictions. If your prediction is wrong, you don’t get anything. If your prediction is correct, your profit is the difference between the price you purchased the contract for and the $1 settlement, minus fees. For example, if you purchased a contract at 30 cents and you were right, then you get 70 cents for every contact you purchased. E.G., if you purchased 100 contracts and you get 70 cents for each contract for being right, you’d get $70.

Take note that the brand also offers $10 contracts and $100 contracts, and they work the same way as the $1 contracts. For example, with a $10 contract you might pay $4 for a contract, versus the $0.40 you’d pay to purchase contracts that settle for $1.

Are Underdog Predictions legal?

The answer is yes, it’s legal to participate in most states in the U.S., with the exception of Arizona, Colorado, Delaware, Illinois, Kentucky, Maryland, Massachusetts, Michigan, Mississippi, Nevada, New Jersey, New York, Ohio, Pennsylvania, and Tennessee.

Note that if you’re also using this platform for DFS and Pick ‘Em contests, the legality varies across different states. So as an example, someone in Ohio may be able to participate in sports Pick ‘Em contests, but they can’t trade event contracts. If you log into the website or app and you can’t find the prediction markets, it’s likely because Underdog is geofencing you since prediction markets trading isn’t legal in your state.

Now that you have an overview of how it works, let’s jump into my review of Underdog Predictions…

Does Underdog offer bonuses?

If you’re already familiar with Underdog Sports, then you may have seen their advertised bonuses for DFS and pick ‘em contests, such as “spend $x, get $y,” or in some cases you’ll see deposit match bonuses. Unfortunately, this platform doesn’t offer any bonuses to users who are participating in prediction markets, so you won’t find an Underdog Predictions promo code, which is on par with similar platforms. Because the platform is more like a financial exchange, it operates under a different business model and regulatory framework compared to the sports side of the site, so users usually don’t get welcome bonuses. If this changes, I’ll certainly update you here.

Secondly, the brand does offer a referral program, where users can get the equivalent of $10 when they refer their friends. However, you get paid $10 worth of bonus entries into the sports contests, so here again this isn’t applicable to users who are strictly interested in the prediction markets. You can read more about this topic inside my full bonus review.

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.

Meanwhile, take a look at my experience with the app…

Underdog Predictions app review

You have options as to how you want to join and participate on the site, which includes the desktop version of the site, the Android app, or the iPhone app. For this review I took a quick look around the website and found it to be well-designed, quick-loading, and overall it offers a good experience. However, for the bulk of this review I’m focusing on the app. Make no mistake, the desktop version doesn’t lack anything, but I prefer the convenience of the app.

When you log into the app, you’ll find a clean, professional user interface that’s mobile-optimized and beginner friendly. The default design is a white background, but those who prefer a dark theme can change it with a quick tap. Once you log in, you’ll be taken to the lobby, and from there you’ll find the “Team Picks” tab, where you can start exploring prediction markets.

Let me stop and make a note here: it’s a good idea to get verified right away by completing the standard KYC (know your customer) identity verification process, as you’ll be unable to access the prediction markets until you complete this step. You’ll find the “Get Verified” tab inside your account.

This app is among the cleanest I’ve seen, and everything is well-organized so that you don’t feel overwhelmed when you log into the app. At the top of the app you’ll find a search feature and a link to make a deposit, as well as sports listings. At the bottom of the app you’ll find your account information, promos available (which do not apply to prediction markets), a “games” tab and more. Whether you’re here just to make prediction picks, or you want to participate in other features such as the Pick ‘Em contests, it’s easy to switch back and forth between these features in the app.

So, what types of prediction event contracts can you purchase? That’s next…

What types of sports predictions markets does Underdog offer?

As I’ve mentioned before, you can actually purchase event contracts across a wide variety of topics, as wide-ranging as climate, culture, politics and more. However, since Underdog started at a DFS/Pick ‘Em platform, I think that their best event contracts are those that are centered around sports. One of the main advantages in trading on sports event contracts on this platform is that their popularity deepens the liquidity. Simply put, if you’re buying an event contract, the site pairs you with people who’ve taken the opposite position. Popular markets means it’s easier for you to buy and sell your contracts relatively quickly – and that’s important when you want to maximize profit or minimize a loss!

So, what sports are covered in the prediction markets? Take a look:

✅ NFL

✅ NBA

✅ NHL

✅ MLB

✅ CFB

✅ CBB

✅ Soccer

✅ Tennis

Across these sports, you can purchase event contracts related to who wins a match or game, spreads, total points, and predictions for individual players, such as points scored or total rushing yards. This list is similar to what you’ll find at PrizePicks, which you can read about in this PrizePicks Predictions prediction market review.

Take note that while the platform features Pick ‘Em contests for esports, at this time there aren’t esports event contracts available. I expect that will likely change in time, and that the platform will offer event contracts on the esports that are already on the site, such as DOTA 2, CS2, League of Legends, Valorant, and Call of Duty.

One really nice feature that makes Underdog standout from other sports prediction markets platforms is the “Combo” pick. This is where you make a prediction pick alongside two or more fantasy picks. You’ll be hard pressed to find this feature on the big prediction platforms like Polymarket and similar sites.

Now before you can get started trading event contracts, you’ll need to fund your account. And that brings us to the next part of my review…

Review of Underdog Predict’s payment options

When you’re ready to fund your Underdog Predictions account, you’ll be able to choose credit cards, debit cards, Apple Pay, and Trustly. I’m a little disappointed that other popular options such as PayPal aren’t available, but the platform must comply with regulatory measures. You’ll see the same options available on similar platforms, which you can read about in my Fanduel Predicts prediction markets review.

For withdrawals, you generally need to withdraw using the same method you used to fund your account, such as a debit card or a bank transfer. These options usually clear in 48 to 72 hours. It’s worth noting here that due to regulatory compliance, your predictions market wallet will be separate from your other activities on this platform. Depending on what you’re predicting, this account may be held by Underdog or Crypto.com, which is a regulated platform that has partnered with Underdog Sports to offer prediction markets.

What are Underdog’s fees for trading event contracts?

In most cases, it appears that you’ll pay a fee of $0.02 for each trade you make, which means you pay this fee for every contact you buy and sell.

For example, if you buy 100 contracts for 30 cents each, that’s $30 you need to spend. However, you’ll also have a $0.02 fee per each of those contracts for a total of $2. In this example, purchasing 100 event contracts will cost you a total of $32. If you exit these contracts early – meaning you sell them to someone else – then you’ll pay another $0.02 per contract.

This two cent fee is pretty standard on many predictions platforms, so I feel relatively neutral about it. Other platforms, such as Polymarket, don’t charge makers, which are the people who add liquidity to the market. Platforms like Kalshi charge makers and takers, with makers often getting lower fees. So while Underdog’s fees are fairly average, it would be great if they lowered them for makers – but it’s not a dealbreaker for me.

Now let’s turn to another important part of my Underdog Predictions prediction markets review…

Review of Underdog’s customer service experience

The first thing I noticed about Underdog’s help and support is that they have a relatively large amount of self-help documentation on the site in the form of FAQs, and you can easily search through these documents. The self-help documents should be able to answer most of your basic questions, such as how to complete common tasks such as depositing or withdrawing from your predictions account.

If the self help documentation doesn’t answer your question, then you can click on the live chat button that’s featured on nearly every page of the site and app. I appreciated that the live support feature told me that the platform was experiencing a higher than normal volume of inquiries, and that it offered up a relatively helpful AI agent. The real test came when I requested a human agent. Despite being warned about the high volume, I was pleasantly surprised to get an agent – and an answer to my question – in about seven minutes. That’s much better than waiting hours to days for someone to reply to an email, so overall I rate this to be a very good experience.

And now here’s an important question…

Reviewing site compliance: Is Underdog Predictions a safe platform?

The short answer is yes, Underdog Predictions is safe. Now let me share with you the longer answer…

Underdog Sports, LLC (doing business as Underdog Fantasy) was founded and launched in 2020 by Jeremy Levine, and it’s headquartered in Brooklyn, New York. By 2022, this company had reached nearly a half a million dollar valuation, and recently this rapidly growing platform hit a $1 billion valuation. In short, yes, this is a reputable company.

The second thing you need to know is that Underdog has partnered with Crypto.com and Kalshi to offer prediction markets. These platforms are regulated by the CFTC (Commodity Futures Trading Commission), so this regulatory framework applies to Underdog Predictions. Since regulatory oversight is provided by the United States federal government, you know that Underdog Predictions is safe and compliant with the law.

Now a few final thoughts for my review…

Wrapping up my Underdog Predictions app review

Overall, I really like the Underdog Predictions app (as well as the website), as it simplifies the process of buying and selling event contracts. While Underdog Predictions does offer a variety of event contracts covering culture, business, finance, climate, and more, I think the people who will benefit the most from using this platform are those who are interested in sports. Your most active prediction markets are going to be sports oriented on this platform, which makes it easier for you to enter and exit these contracts. In addition, sports lovers will appreciate having all their DFS, Pick ‘Em contests, and sports predictions markets all housed in one sleek, user-friendly app.

When you’re ready to jump in to start trading event contracts, all you have to do is tap the Underdog banners on this page to get started. You never know, maybe I’ll take a position on the other side of your event contracts, and we’ll see who’s right!
