A brand new entrant into the prediction markets field, Underdog does not yet have a dedicated promo code, as the focus has first been on a flawless launch and regulatory rollout.
As a result, new users won't find a specific welcome bonus tied to Underdog just quite yet, a branch of the main Underdog app's core DFS offering, which includes a plethora of bonuses in the form of deposit matches and bonus entries.
However, given Underdog's history of stellar promotions, we expect an Underdog may have a welcome offer in the future.
Be sure to check back to the VegasInsider's exclusive coverage of Underdog, as trading credits or fee waivers might become available in the 27 states regulators have thus far approved.
Underdog Partners With Crypto.com for Sports Events Contracts
Announced on September 2, 2025, the partnership between Underdog and Crypto.com Derivatives North America (CDNA) marks a major step forward in sports event contract innovation.
The collaboration embeds a full prediction market exchange into the Underdog app — a natural evolution for one of the fastest-growing sports companies in the world.
Now valued at $1.23 billion following a $70 million funding round in March 2025, Underdog has expanded beyond fantasy sports through CDNA’s CFTC-registered market technology, becoming a modern, full-stop sports gaming company.
Founded in 2020 by Jeremy Levine, Underdog made its name disrupting the daily fantasy sports (DFS) space with its pick’em and best ball formats.
The user-friendly Underdog app has attracted millions of users and helped the company gain national market share through its growing product lineup.
Its latest venture into sports prediction markets—spearheaded by CEO Jeremy Levine—targets a larger target audience than previous fantasy market access.
The partnership traces back to mid-2025 discussions as interest in prediction markets surged, driven by the success of platforms like Kalshi and Polymarket.
Underdog's Impressive Expansion Into Sports Events Contracts
Already available for fantasy contests in more than 41 states, Underdog sought a path into even more markets. Thanks to Crypto.com’s Commodity Futures Trading Commission (CFTC) approval to offer prediction markets, Underdog can now expand through its proprietary technology, which is built on the same trusted framework behind its fantasy product.
Prediction markets differ from traditional betting by using a peer-to-peer exchange where contract prices reflect implied probabilities, settling at $1 for correct outcomes and $0 for incorrect ones.
The rollout, targeted for 16 states — including Alabama, California, Florida, Texas, and Wisconsin. Since launch, they’ve expanded to 27 states plus Washington DC.
Industry analysts project that sports event contracts could generate more than $500 million in profit in 2025, complementing a sports market already producing $16 billion annually.
On the product side, the partnership enables existing Underdog DFS players to access prediction markets instantly, meaning no new apps or crypto wallets are required.
As one of the first DFS operators to enter prediction markets, Underdog unites fantasy picks and trading markets into one ecosystem. CDNA, meanwhile, oversees all clearing and compliance, ensuring full federal oversight.
How the Underdog and Crypto.com Partnership Works
Underdog's and CDNA's innovative offerings make for a solid foundational partnership as they comply with the Commodity Futures Trading Commission regulations, combining operational excellence with simplicity and security.
The Underdog app will serve as the front-end interface, allowing users to browse and trade contracts leveraging Underdog's backend technology for real-time price and contract execution.
Also among the most exciting developments, CDNA-issued contracts qualify these trades as commodity futures..
As a result, Underdog's prediction markets are legal in non-betting states, though they will face constant battles from critics of the prediction market community.
How to Sign Up for Underdog
Starting with the existing Underdog app, the company has made it seamless for existing fans already using the DFS pick'em or best ball contests.
For new users, this means starting with a standard Underdog account, which automatically unlocks the prediction markets feature upon verification in eligible states. Though no separate welcome offer exists yet, in the future, this would be the stage to enter a prediction specific promo code for bonuses related to trading markets.
Existing Underdog users in the 27 states where Underdog has launched simply need to make sure they have the latest update in the app store, without re-verification, and can then toggle between fantasy and prediction markets.
With more access on the horizon, be on the lookout here at VegasInsider if your state is not yet eligible.
For new users, below is a quick guide on how to get on the platform today and get acclimated with this unique technology partnership between Crypto.com and Underdog.
- Download the Mobile App: Available in both the Apple App Store and Google Play Store, search for "Underdog Fantasy" where you'll then be prompted to install the app.
- Create a New Account: From here, with the app now open, tap the "Sign Up" button. Enter your email, password, and provide basic information like your first and last name and date of birth. When prompted for a promo code, you can enter one for DFS bonus..
- Verify Your Identity: In order to use Underdog, you will need to verify the last four digits of your Social Security Number and link your phone number via an SMS code. This helps stay compliant with the CFTC, and ensure secure trading in less than two minutes.
- Make Initial Deposit: You will now be prompted to make an initial deposit, with options available such as debit card, PayPal, Trustly, or Apple Pay. With a minimum of $10, funds will appear instantly for trading.
Access the Prediction Market Platform: You are now finally ready to browse markets, which you can find on the "Prediction Picks" tab at the bottom of the app navigation menu. There is a market likely for you already available.
How to Access the Underdog App
Once you have the Underdog app open, navigate to the "Picks" section.
State regulators require Underdog to use geofencing to ensure the prediction markets' features are only available in the 27 states where they are available.
Once you tap it, you will unlock a dashboard of live markets, filterable by sport (i.e., MLB, NFL, NBA, etc.), browse real-time prices, and see the implied probabilities of each option. If you want to take a deeper dive, say on props, you can also search.
In one really cool feature, you can mix your games as the tab integrates with your fantasy lineup builder, allowing combo entries where a Predict contract matches a DFS pick.
Also, be sure to turn on push notifications for price alerts when markets are volatile, as in a sportsbook, prices are always changing as well.
Underdog Prediction Picks
Prediction Picks, Underdogs' new prediction markets product, is transforming passive fans into active traders by letting them buy and sell event contracts on real-world outcomes, ranging from sports to political outcomes.
Unlike fixed-odds betting or crypto trading, which require a blockchain, prices in prediction markets fluctuate based on supply/demand, immediately reflecting crowd wisdom in real-time.
Let's take a closer look at some of the key terms you should know about:
- Contracts: The one thing you should be clear on is contracts, the core asset of prediction markets. These are essentially digital shares that get you in the game and are tied to binary outcomes, such as "Team A Wins" or "Player X over Z state." Just like in financial markets, the game is to buy low and sell high, selling anytime before settlement to lock in profits. Multiple contracts can be purchased to grow your position, but all buy/sell activity must be done prior to the event starting. Fees apply per trade, and the Underdog combo features let you play on Predict with more picks simultaneously.
- Payouts: All correct predictions yield $1 per contract, while incorrect selections get $0. Your net profit will be $1 minus the purchase price/fees. As an example, if you buy at $0.70, the payout of $1 nets $0.30 per share. Processing time takes up to 24 hours post settlement, with profits immediately credited to your balance for reinvestment.
Implied Odds: Contract prices also reflect the implied probability of the events happening (or not), and there are no traditional +EV odds in play here. As an example, a $0.55 price on "yes" implies a 55% chance of success. If you think that is mispriced, this would present a buy opportunity if you think the probability is higher.
Examples of Underdog Prediction Picks
Now, let's take a closer look at a couple of hypothetical but realistic examples of NFL markets. Using Underdog’s model, the following examples assume a $10 entry across 10 contracts, plus a $0.20 fee. This is NOT investment advice, rather an example on how these markets work.
Winning Contract Example:
You trade on “Pittsburgh Steelers to win vs. Los Angeles Chargers” in Week 10 of the NFL season, with the Steelers priced at $0.30 (implied 30% odds), reflecting what you see as undervalued odds for Aaron Rodgers in primetime. You buy 10 contracts: $3.00 + $0.20 fee = $3.20 total.
The Steelers win 24–21; each contract pays out $1, totaling $10. Net profit = $10 − $3.20 = $6.80.
Losing Contract Example:
Using the same game, you take a contract on “Aaron Rodgers over 210.5 passing yards” at $0.60 (60% implied odds), backing the “yes.” You buy 10 contracts: $6.00 + $0.20 fee = $6.20 total.Rodgers throws for only 190 yards, so your contracts expire worthless. Total loss = −$6.20.
What Sports Will Be on Underdog's Prediction Market?
With the launch of Underdog's prediction market, customers can now trade sports event contracts based on their opinions across all major sports, including the NFL, college football, NBA, MLB, and more.
Prices continuously reflect real-time market sentiment, allowing Underdog users to buy or sell contracts instantly as opinions shift.
Still in its early stages, Underdog debuted prediction markets with football in September, added MLB in October, and integrated the NBA later that month. Underdog is expected to have a full slate of sports by mid-2026.

Rising Popularity of Prediction Markets
Far from being the only operator in the prediction markets space, there is no doubt that the industry has exploded in popularity in 2025.
Blending a mix of finance, crypto, and sports fandom, the industry is now thought to be a $2 billion sector, with sports driving around 60% of the total volume.
In terms of the competition, Kalshi leads the way with $1B+ in monthly trading volume, in large part thanks to their Robinhood partnership, making them legal in all 50 states.
Polymarket is next up on the list, with $3.6B in 2024, led by the US election trading. Sports betting giants are also now getting into the mix, with DraftKings and FanDuel soon launching their own operator-owned platforms for prediction markets.
Underdog Banking Options
Just like its fantasy product, Underdog offers streamlined and secure banking options designed for live trading with low fees.
Focusing on fiat currency over crypto, Underdog remains compliant with CFTC regulations and intentionally excludes credit card payments.
Currently, only debit cards (including Apple Pay) and Trustly can be used for prediction market deposits and withdrawals.
Underdog Deposits
- Debit Cards (Visa/Mastercard, including Apple Pay): $10 minimum
- Trustly (Online Banking): $10 minimum
Underdog Withdrawals
- Trustly: 1–3 days
Responsible Trading Practices on Prediction Markets
Just like with DFS or sports gambling, trading on prediction markets requires discipline and managing your emotions. With real-time user sentiment swinging markets' implied probability, certain markets can be wildly volatile with price shifts of 20% or more, regularly.
Some tips for responsible trading on prediction markets include starting small, diversifying across different markets, and tracking implied probabilities over true probabilities once markets settle.
Underdog also does a great job as an operator of deploying tools to assist in responsible trading, including the ability to set deposit/loss limits, time-out periods, self-exclusion lists, and lockout periods.
