Our comprehensive Underdog Predict review delivers everything you need to know about navigating one of the most innovative sports trading platforms in the United States. If you want a detailed look at how this exchange stacks up against traditional platforms, this guide is for you.
Top Underdog Predict Alternative for October
In this Underdog Predict review, we’ll explore how the brand’s major acquisition of Aristotle Exchange completely transforms your trading experience. You’ll discover how the platform charges a small, flat per-contract exchange fee rather than a percentage-based commission, how the unique hybrid “Combo” features function, and what steps you need to take to clear account verification.
Historically a leader in daily fantasy sports (DFS), Underdog has undergone a massive transformation recently. While the platform initially entered the event contracts space through a partnership with Crypto.com’s U.S. derivatives arm (CDNA), its March 2026 acquisition of Aristotle Exchange (a CFTC-registered DCM and DCO) gives Underdog the regulatory infrastructure for its own exchange and clearing operations.
Underdog now has its own CFTC-regulated exchange, but it also offers contracts through Kalshi and Crypto.com’s CDNA. The exchange behind your selection determines which contract rules apply.
Once inside, you can access binary “Yes or No” contracts across major professional leagues, select collegiate events, as well as new cultural and political markets. Currently, the platform is seeing significant volume on upcoming global tournament and seasonal futures contracts, where traders can predict group winners or qualification outcomes for prominent teams.
Key 2026 Platform Updates:
Native Exchange:
Underdog now owns and operates its own CFTC-registered exchange infrastructure through its Aristotle Exchange acquisition. Its own exchange sits alongside Kalshi and Crypto.com’s CDNA in the platform’s current offering.
Expanded Markets:
In addition to standard sports leagues like the NFL and NBA, the platform’s lineup features dedicated “Culture Markets”, allowing participants to trade contracts on non-sports categories like politics, awards shows (Grammys, Oscars), the economy and business, and crypto prices.
The “Combo” Feature:
Combo Entries let you combine up to eight Prediction Picks with two to eight Fantasy picks, subject to the options available in your account. The two portions settle separately. If Fantasy Cash Out is available, accepting it closes only the Fantasy portion; your Prediction Picks settle independently.
Pending Acquisition by IG Group:
In July 2026, Underdog agreed to be acquired by UK-based IG Group in a deal worth up to $1.3 billion. Underdog is expected to continue operating as a standalone brand within IG’s portfolio once the deal closes, which is anticipated in late 2026 or early 2027 pending regulatory approval.

Underdog Review: A Closer Look at Underdog and Its Prediction Markets
Now that we have established the concept behind prediction markets and confirmed the legal side of things, let us focus this next section of our Underdog review on our latest experience.
Usability: Open Contracts Through the Desktop Site or the Underdog App
First and foremost, it is worth disclosing that you can only execute trades on Underdog prediction markets after passing verification checks and completing your player profile. This can be completed quite easily by clicking on the ‘Verify Now’ prompt when finalizing your first transaction or via your account balance screen.
When working our way around the desktop site, we found that the prediction market layout is open for anyone to view and browse upcoming lines. Once authorized, however, you can then place trades seamlessly on a well-designed desktop site or opt to enjoy the prediction market experience on the go through their unified mobile application.
The desktop site allows you to freely filter through various sports by clicking on the relevant header. This then opens the upcoming schedule and allows you to review futures. Trending games will be shown first, alongside popular contracts. A click on the contract price will then add it to your prediction slip.
Before enjoying the same experience on the go, you will need to download the app. This can be achieved by clicking on the tabs within the footer of the page or heading directly to the App Store or the Google Play Store. Here, you will see the familiar Underdog logo and be able to download it to your device within a matter of seconds. Once loaded, you’ll find the products available in your state together in one app, with a layout designed for smaller screens. Where both are offered, you can switch between fantasy pick-em games and event contracts. Some states offer Prediction Picks without access to Pick’em or Drafts.

Registration: Become a Member of Underdog
Signing up for Underdog is designed to be a quick and easy process. Whether you’re using the mobile app or the desktop site, you can expect to complete your registration and verification in just a few minutes. Follow these steps to set up your account and start exploring the market today:
Visit the Underdog Platform:
Head to the official Underdog website via the links on this page or download the app from the iOS App Store or Google Play Store. Once you’ve done that, tap the “Sign Up” button to get started.
Enter Your Account Details:
Create a unique username, provide your email address, and create a secure password.
Provide Personal Information:
To meet regulatory and security standards, you’ll now need to enter your full name and date of birth.
Complete Identity Verification:
You’ll then be prompted to provide additional details, such as your residential address and the last four digits of your Social Security Number (SSN).
Enable Geolocation:
Because Underdog must operate within specific legal jurisdictions, you will need to allow the app or browser to verify your physical location. This ensures you are playing from a state where Underdog Predict is legally allowed to operate.
Fund Your Account:
Once verified, navigate to the cashier section. Underdog makes it easy to add funds using popular methods like Apple Pay, Visa, Mastercard, and Trustly bank transfers. After your deposit is processed, you are ready to start trading!
Funding the Experience: Deposit Using Trusted Methods at Underdog
Once you have created and verified your account, you will need to make a deposit. Currently, this is possible through Visa and Mastercard credit cards, Apple Pay, and direct online banking powered by Trustly. Note that while Underdog also accepts PayPal and Venmo deposits for its fantasy contests, funds deposited via those two methods currently cannot be used for prediction market entries specifically.
Because Underdog uses a unified platform wallet, your deposited balance can be seamlessly applied to both your traditional Daily Fantasy Sports (DFS) contests and your active prediction market event contract slips without needing separate transactions.
We found that the minimum deposit is set at $10 across the board, and no additional fees will be taken. The same is true of withdrawals. However, we also found that you can request to clear your account even if you have under $10 in it.
Bonuses: Built for DFS but Accessible Via a Clever “Combo” Workaround
When looking at
Underdog promos, you will find various “Play and Get” campaigns, active user rewards, and a refer-a-friend program. However, if you are strictly an event contracts trader, the rules require a bit of navigation. Underdog’s official terms explicitly state that all platform Promotion Bonuses, bonus cash, and bonus entries are designed as a substitute for entry fees into fantasy sports contests.
Because of this, you cannot use these promotional funds directly to purchase standalone prediction picks on Underdog Predict. Despite this initial restriction, the official rules outline a legitimate workflow for traders via integrated “Combinations” or “Combo” entries (slips that mix fantasy sports picks with prediction event contract futures). Here’s exactly how the system operates:
The Funding Phase
– You build a Combo entry and fund the transaction using your active Promotion Bonus or Bonus Entries. The platform routes this entry through the fantasy contest node of the slip.
The Clearance Process
– Underdog’s official terms explicitly waive the standard 1x turnover requirement for the portion of the promotional credit allocated to the prediction market event contract future segment of the combo slip.
The Allocation
– This contract-clearing waiver allows those specific promotional funds to safely clear the fantasy restrictions, ensuring that any net winnings generated from the prediction contract side of that combo slip settle directly into your account as immediately withdrawable cash.

Contracts: Understanding Pricing and Payouts
The idea of
prediction markets trading
revolves around successful outcomes and losses, buying and selling, and yes-or-no answers. In this section of our Underdog review, we ensure that you have a full understanding of what to expect.
Sports
Initially, prediction markets were introduced at Underdog with contracts available for the NFL, NBA, MLB, NHL, and CFB. However, the platform’s lineup continues to expand to include major professional and collegiate leagues, alongside dedicated
culture prediction markets. As already established, you can look to open contracts on teams “to be successful” and various game-level or tournament outcomes, such as moneylines, point spreads, point totals, and seasonal futures. Player-stat selections are now available as Prediction Player Picks too, although access depends on your location. Check whether your selection is a fantasy pick or an event contract before entering.
Contract pricing
The price of each contract is based on probability and is valued off a dollar. For example, if a contract has a price of $0.65, it has a 65% expected chance of success. You can buy more than one share at a time, and each will be valued at the same contract price. With this example, purchasing 10 contracts would cost you $6.50 before fees. Underdog applies a small, flat exchange fee per contract on top of this, rather than a percentage-based commission, so your final checkout amount will be slightly higher than the raw contract price.
Payouts
Although it is possible to cash out your contracts early to lock in profits or minimize losses, you must be physically located within one of Underdog’s 46 eligible states or Washington D.C. to execute this feature. If you travel to an ineligible location, you won’t be able to place new entries or cash out until you return to an eligible jurisdiction. Your existing positions remain active and settle normally. If you opt to let your contracts run until the event concludes, you will find that winning payouts automatically settle at a flat $1.00 per contract. Of course, any losses will settle at $0.00, and the contract will be closed.
Fees
Like any tradable assets, prediction markets revolve around pricing, and Underdog keeps things straightforward by charging a small, flat exchange fee per contract rather than a percentage-based commission. This fee is added to the contract price at checkout, so there are no surprise deductions once you’ve confirmed your trade. However, the below is an example of what to expect from a successful contract based on Underdog’s own published fee example
10x contracts purchased at $0.65:
$6.50
Exchange fee ($0.02 per contract):
$0.20
10x successful contracts:
$10.00
Total profit ($10.00 – $6.70):
$3.30
This is just a hypothetical example, and it’s important to keep in mind that profits are not guaranteed and actual exchange fees may vary by contract. When a contract hits a successful outcome, the winnings will settle into your available in-app balance immediately. Note that if you decide to request a withdrawal from the platform, standard external banking withdrawal processing times can take up to 72 hours to clear.
Combos
Combos let you submit one or more Prediction Picks alongside at least two Fantasy picks. Review the rules and potential payouts for both portions before confirming, as they have different settlement arrangements. If Fantasy Cash Out is available, it applies only to the Fantasy portion of your Combo. The Prediction Picks settle and pay out independently, so accepting a Fantasy Cash Out doesn’t close those positions.
Support: Reliable Support Is Available at Every Turn
While the platform routes all inquiries through a unified help interface rather than keeping separate department lines for event contracts, Underdog features an entirely dedicated support directory specifically for Underdog Predict questions. You will be able to get in touch with agents around the clock through the 24/7 live chat feature. Initially, you will be presented with past chats, common FAQs, and the option to share your current query with Underdog’s automated Fin AI Agent.
If unable to assist, we found that you can request to be connected with a live agent. Generally, responses are swift, but during busy times, we have seen responses take up to 30 minutes. Alongside the live chat widget, you can also reach the team directly via email for more complex portfolio issues. Away from direct messaging, you’ll also find a help center, which provides clear answers to some standard issues.
Verdict: Underdog Delivers a Premier Native Prediction Exchange
Underdog secures a pioneering role in the event contracts space through its major acquisition of Aristotle Exchange, taking direct control of a federally regulated DCM and DCO license pipeline. Operating across 46 states plus Washington D.C. with a straightforward, flat per-contract fee structure, the platform integrates CFTC-regulated binary contracts on major sports and culture markets directly into its unified app environment.
Also worth noting is that Underdog itself is set to change hands, having agreed in July 2026 to a deal worth up to $1.3 billion with IG Group, though it’s expected to keep running independently under the new ownership once the deal closes.
We also liked that Underdog offers unique “Combo Entries” that give traders a way to put fantasy promotional funds toward an entry that includes a prediction market pick. Supported by 24/7 live chat and email assistance, this innovative hybrid design delivers a secure and highly versatile ecosystem that is well worth exploring.
Underdog Review FAQ
Prediction markets allow you to open positions based on possible outcomes of upcoming fixtures. At Underdog, this includes opening contracts based on teams you believe will be successful and various game-level or tournament outcomes like point spreads and seasonal futures.
Yes. Although nothing is guaranteed, you can secure a real money payout with every successful contract. Winning contracts automatically settle at a flat $1.00 per share, meaning your possible net profit is determined by the discount you secured on your initial probability-based purchase price.
It depends on your destination. You must be physically located somewhere the relevant Underdog prediction product is available to place trades. Traveling to another supported state doesn’t automatically prevent you from trading.
Underdog agreed in July 2026 to be acquired by UK-based IG Group in a deal worth up to $1.3 billion, though it’s still pending regulatory approval and isn’t expected to close until late 2026 or early 2027. Nothing changes for existing users in the meantime, and Underdog is expected to keep operating as its own standalone brand under IG’s ownership once the deal does close.
Underdog Prediction Picks are available in 46 states plus Washington, D.C. You must be 18+ and physically located in an eligible jurisdiction to trade. They aren’t available in Arizona, Michigan, Nevada or New York, or in Ontario and U.S. territories.
While you cannot use promotional funds directly to purchase standalone prediction picks, Underdog allows you to bypass this via integrated ‘Combo Entries’ that mix fantasy sports picks with prediction market event contract futures.
