Underdog has been one of the best DFS apps for awhile now in the U.S., and in September 2025, it made a push into the prediction market space with a new product called Underdog Predict.
The idea behind Underdog Predict is pretty simple once you see it in action. You’re trading contracts based on how you think a real game will play out. You choose an outcome, and that selection becomes a contract with a live market price.
Say you take a contract tied to Carolina’s performance, and it’s sitting at $0.26 (or about +285 in American odds format).
That number reflects the market’s view of Carolina’s chances, which basically means the crowd is pricing that outcome around 26%. If you think their chances of winning are higher than 26%, you can buy shares.
If Carolina comes out hot and the sentiment flips, that contract might jump to something like $0.60. At that point, you could close your position. Buying at $0.26 and selling at $0.60 would create a gain of $0.34 per contract.
If you decide to hold and you end up being correct, you win $1 per contract. If it doesn’t, you lose the amount you paid to enter. The exchange fee is already baked into the price, so what you see is what you pay.
Right now, Predict is available across the NFL, college football, NBA, college basketball, MLB, and more. These are all in the Team Picks section of the app.
Underdog also rolled out Culture Markets, which cover non-sports events across politics, awards shows like the Oscars, weather, Fed decisions, and other real-world categories.
One thing that really sets Underdog apart is the cross-product flexibility. Predict is in the same app as Underdog DFS. You can switch modes and even build entries that combine Predict contracts with traditional DFS player selections.
There are still some limitations. Unlike platforms like Kalshi, you can’t set your own price or place limit orders. You’re trading at the current market price, which gives you less control if you prefer setting your own entry point.
In this Underdog Predict review, I’ll walk you through the promo code and sign-up bonus, how it works, what I like, what could be better, and how it compares to the rest of the prediction-market landscape.
Ratings by Category
Overall Rating
74.5/100
Underdog Predictions Picks is a strong new entrant with excellent design and usability, but it still trails the more established prediction exchanges in pricing, market depth, and feature set.
Fees
32/40
Underdog charges a flat $0.02 fee per contract. This is significantly more expensive than Polymarket and Kalshi.
User Experience
12.5/12.5
Underdog is easily the best trading app in terms of usability and functionality.
Market Variety
4/12.5
Underdog offers a limited selection of sports and limited trading options per sport. It also doesn’t offer non-sports prediction markets like the competitors.
Limits & Liqudity
9/12.5
Liquidity is strong almost everywhere, but they have a $25k cap per market, which is tighter than other apps.
Customer Reviews
12/12.5
Underdog has a 4.9 rating in the App Store and an excellent reputation on Reddit and other forums.
Tools & Features
1.5/5
Underdog doesn’t have automation tools or advanced features like other trading apps.
Banking
3.5/5
Underdog is one of the few trading apps with free withdrawals. However, I had to dock points because they offer only a few payment methods.
My Favorite Parts About Underdog Predict
- Awesome UX. The app is fast, intuitive, and easy to move through. Markets load instantly, and everything sits in a layout that feels natural even if you’re new to trading-style products.
- Combos with DFS. You can mix Predict contracts with regular DFS picks in the same entry, something no other major platform offers. If you already play on Underdog, this makes the whole experience feel seamless.
- Strong liquidity. Markets remain active across the board, making it easy to enter and exit positions without hunting for a price. Liquidity holds up even outside the biggest games.
- Accepts Apple Pay. Underdog is one of the few prediction markets that supports Apple Pay, making it easy to deposit straight from your phone.
- Free withdrawals. No matter how you withdraw, there are no fees attached. Some competitors tack on fees here, so this stands out as a selling point.
Where Underdog Predict Could Improve
- No limit orders. You can’t post your own price or place a limit order. All trades execute at the live market price shown, which limits control for users used to maker-style trading.
- Limited market variety. There are fewer markets available across both sports and culture than bigger competitors. If you like niche sports, mentions markets, or other popular markets on apps like Kalshi, the selection may feel tight.
- Higher fees. Each contract includes a fixed exchange fee baked into the entry price, which accrues faster than on percentage-based structures on other platforms.

Underdog Market Variety
Right now, Underdog is offering prediction options across 8 sports leagues with plans on adding more soon:
- NFL
- NBA
- NHL
- MLB
- College football
- College Basketball
- Soccer
- Tennis
Each game comes with three types of prediction choices:
- Outright Winner: Simply pick who will win. Payouts on each side can vary significantly based on what the market thinks is most likely.
- Spreads: Each team's winning margin is adjusted by a set number based on which is more likely to win. For example, if the Eagles are playing the Raiders in an NFL game, the Eagles may have a spread of -7, since they're expected to win easily. Spread contracts tend to be priced closer to 50c on each side.
- Totals: You’re predicting whether the combined score of the game will land above or below the set number. These contracts also tend to be priced close to 50c on each side.
Underdog also offers Combos, which let you pair one prediction contract with 2 or more fantasy picks in the same entry. You can add up to eight fantasy selections.
Underdog also has Culture Markets beyond sports, covering the Grammys, the Oscars, politics, economic data, business headlines, crypto price movements, and more.
Underdog Predict Fees & Limits
Each contract you trade comes with a small exchange fee that is already built into the entry price you see on the screen.
You don’t get hit with extra add-ons at checkout, and there are no surprise charges when a contract settles. What you see upfront is the full cost of the trade.
Fees
Each Predict contract includes a $0.02 exchange fee, and Underdog shows this directly in the estimated entry cost before you confirm a trade.
Settlement is fixed at $1 per contract if the prediction is correct and $0 if it is not. There are no settlement fees, and nothing additional is deducted from the payout.
Limits
Underdog sets a clear maximum entry limit of $25,000, and that cap is displayed right on the trade ticket. You can scale your entry using the quick buttons +$10, +$20, +$50, or type in your own amount if you prefer.
No matter how you adjust it, you cannot go above the $25,000 limit.
How Trading on Underdog Works
Trading on Underdog Predict feels familiar if you’ve ever traded anything with a live price attached. Instead of choosing players or building a fantasy lineup, you’re selecting a real game outcome and entering a contract tied to that event.
The price is always between $0 and $1, and that number reflects the market’s current view of the likelihood of the outcome.
The markets use American odds by default, but you can also switch to percentage view which will show the implied probability of each outcome directly, much like Kalshi and Polymarket.
When you open a market, you’ll see a clean screen with two sides to choose from. You pick the outcome you feel offers the stronger case and enter the amount you want to put in. The app immediately shows the contract cost and the potential $1 settlement if your prediction is correct.
The entry price is basically the market’s temperature check at that moment. If new info rolls in, such as an early momentum swing or a surprising start, the price updates automatically.
Entering a Position
Once you enter a position, the screen switches to show your active contract. You get your entry price, the current live price, and options to add more contracts or close the position. Prices move in real time, so you can adjust quickly if things start trending in a different direction.
Underdog keeps the trading mechanics straightforward. There’s no order book or limit orders, which make things straightforward but gives you a bit less control. You trade at the live price you see, and your position shifts with the market as the game unfolds.
You can close out of your position at any time but clicking the cash out button. Depending on the current price, you may make a profit or be paid out less than you initially traded.
Risk, Price, and Settlement
Every contract has a clear range of outcomes: the most you can lose is what you paid upfront, and the most you can receive is $1 per contract if the prediction is correct.
The overall setup is designed to feel approachable. All pricing is displayed in dollars, fees are already included in the entry cost, and moving in or out of a position takes only a couple of taps.
If you’ve used Underdog’s fantasy interface before, the Predict screen should feel familiar, just with live contract pricing instead of player projections.
My Experience Using the Underdog App
Underdog offers Predict inside the same app where you’ll find its other products, including Champions and Drafts. Everything lives under one roof, which makes the experience feel smooth whether you’re trading event contracts or building out fantasy entries.
The app is also one of the highest-rated in the space, with ratings of 4.9 on iOS and 4.7 on Android.
You just need to make sure you’re in an eligible state. If you open the app from a restricted location, Predict simply won’t appear, even if you can access the rest of the platform.
I’ve used Underdog for fantasy contests for a while, so I was genuinely curious how Underdog Predict would fit into an app I already knew inside and out.
The transition turned out to be smoother than I expected. You don’t feel like you’re jumping into a different product or learning a new layout. You tap into Underdog Predict and the whole thing feels familiar right away, almost like it’s been part of the app the entire time.
Interface & Navigation
When I started clicking around, the layout felt exactly like what I’ve come to expect from Underdog. It’s intuitive and easy to navigate. You can switch between leagues right at the top, and each tap loads the new slate immediately, so it never feels clunky or slow.
When I opened a specific game, the live context popped up immediately. I saw the score, game clock, down and distance, and field position all in one glance.
Right under that was a gold liquidity tracker, like 12.2K, showing how much activity that market was getting. It is a small touch, but it helped me quickly gauge how engaged other users were in that event.
Underdog also makes it obvious when you are in a Predict market.
There is a small blue icon under each market tile that links the contract to Crypto.com Derivatives North America (CDNA), the regulated exchange behind the product. It is a subtle cue that helps separate these markets from standard DFS picks.
Each market was laid out as two outcomes side by side, each with a live price. I could switch the view into an American-style pricing format like +335 or -358, which I actually used a few times because it gave me another way to interpret the contract value.
Tapping the small “i” icon brings up a clean breakdown explaining how contract settlement works: entry cost, number of contracts, the baked-in exchange fee, and the fixed $1-per-contract settlement if the prediction ends up being correct.
The trading breakdown was simple to follow, and I never had to guess what any of the numbers meant.
Opening a Trade
When I selected an outcome, a bottom sheet opened with a simple entry panel. It showed:
- The contract price
- The estimated payout
- The implied multiplier
- and the full cost, including the exchange fee.
Everything was laid out in dollar terms, so I didn’t have to decode anything.
I could type an amount manually or use the quick buttons (+$10, +$20, +$50). The numbers update instantly as you adjust the entry. When I confirmed, the trade executed immediately at the live price shown, without any order book or pending state.
Managing Positions
After I entered a contract, the game tile showed the number of active picks at the bottom, like “0 picks” or “1 pick.”
When I tapped back into that same event, the screen shifted from the standard two-outcome layout into a ticket-style view.
That view showed the exact details of the position I had just opened, so I could see everything tied to my entry in one place.
Underdog Predict Banking: Deposits, Withdrawals, Payout Speed
Underdog uses a separate banking system for Underdog Predict, so not all Underdog DFS banking options are available.
This is the key thing to understand before you start trading, since deposits and withdrawals for Underdog Predict run through a different setup than the rest of the platform.
Deposits
Only certain deposit methods can be used for Predict, and the list is narrower than what you get on the fantasy side.
Allowed deposit methods include debit cards, Apple Pay, and bank transfer via Trustly.
Venmo funds, credit cards, and PayPal deposits are not supported for Underdog Predict.
Withdrawals
Underdog states that withdrawals for Underdog Predict are handled the same way as regular Underdog withdrawals, although there are a few specific rules to keep in mind.
You can withdraw through PayPal or through Trustly using online banking. The minimum withdrawal amount is $10, and every withdrawal is free with no additional fees.
Payouts can take up to 3 days, but they are usually faster, in my experience.
For security, you must confirm the withdrawal by clicking the link sent to your email within 10 minutes. If you don’t confirm within that window, the request is automatically canceled.
Underdog Background
Underdog Fantasy launched in 2020, led by Jeremy Levine, the same founder behind Draft and StarStreet.
Right out of the gate, Underdog aimed for a fantasy platform that was easy to get around and didn’t drag the way traditional options often do. It caught on quickly, and Underdog became especially popular in the Best Ball space.
Over the next few years, the platform added daily pick formats, season-long contests, and a few other simple game types. Even as the options expanded, the app stayed easy to navigate, which helped it stand out from more traditional DFS sites that can feel heavy or dated.
In September 2025, Underdog launched Underdog Predict, a new way to trade $0 to $1 event contracts on sports outcomes. Underdog is a registered FCM offering event contracts. Trades are placed on CDNA, a registered DCM, powered by UDM Services, LLC.
Underdog Predict sits inside the same Underdog app as the fantasy products. Users can move between fantasy entries and market-based contracts without switching platforms, making the whole setup feel natural and familiar.
Underdog Predict vs. Kalshi: Side-by-Side Comparison
I’ve spent a lot of time using both Underdog Predict and Kalshi, so I compared them across the areas that matter most.
- Interface. Underdog lays out each market the same way it lays out its fantasy contests, with the score, clock, and key game info right above the two outcomes and a blue CDNA badge showing you’re in Underdog Predict. Kalshi feels more like a traditional trading platform, built around category hubs and deeper menus instead of a game-first layout.
- Price display. Underdog gives you a cent-style view like 0.42 or 0.67, plus the option to switch to an American-style display. Kalshi offers multiple display formats, including probability- and payout-based options, but it generally presents more data on-screen.
- Order types and control. Underdog executes every trade at the live price you see. There’s no limit order system, no order book, and no ability to post your own price. Kalshi offers more control. You can fire an instant order or set a maker order on the book and wait for a match. That flexibility is the biggest real-world difference between the two.
- Fees and cost structure. Underdog uses a flat model, with a small CDNA exchange fee already built into the entry price, so what you see upfront is your full exposure. Kalshi uses a maker-taker setup, where maker orders can cost less but only fill if another user matches your posted price.
- Sports trading markets. Underdog Predict offers team picks, spreads, and totals. Kalshi offers a much wider range of prediction options, including season-long questions and league-wide outcomes.
- Sports coverage. Underdog Predict markets are available for major leagues displayed in the app (NFL, NBA, NHL, college sports, soccer). Kalshi covers all of those plus niche categories like chess, esports, and motorsport. It also offers non-sports categories like politics, economics, tech, climate, and more.
- Social and community features Underdog Predict don’t include social tools. Kalshi has an Ideas feed, verified trader profiles, and a public leaderboard.
Underdog Predict FAQ
What is Underdog Predict?
Predict is Underdog’s new product, launched in September 2025, that lets you trade event contracts tied to real sports outcomes. Instead of drafting players, you’re choosing an outcome from a live game and trading a contract priced between $0 and $1.
How do these contracts work?
Each contract has a live price between $0 and $1 that reflects the market’s view of the outcome. If you enter at $0.28 and the price climbs to $0.60, you can close the position or hold through the finish.
How do prices move in real time?
Prices shift as the game swings and market activity changes. Everything updates instantly inside the interface. If the game is live, you’ll see the contract move without any lag.
Are Underdog Predict separate from the fantasy side?
They live in the same app but operate as a separate product. Underdog Predicts uses a different system and displays a small blue CDNA badge under each market. You can move between fantasy and predictions without switching accounts.
Which sports are supported?
The current list includes the NFL, NBA, NHL, MLB, soccer, college basketball, and college football. Whatever appears in the top navigation bar within the Underdog Predict lobby is available for trading.
What types of markets does Underdog offer?
Each game comes with three options: team picks, spreads, and totals. All three sit right on the main market screen.
What does entering a trade look like?
Selecting a side opens a bottom sheet that shows the contract price, estimated return, implied multiplier, and the full entry cost, including the CDNA fee. You can enter an amount manually or use the preset buttons, such as +$10 or +$20.
How do I track an open position?
Your active picks show up on the game tile right after you enter. Reopening that event switches the layout to a ticket-style view with your entry price, current value, and options to add more or close the position. Everything updates in real time.
How do fees and limits work?
Each contract includes a small CDNA fee baked into the entry cost, so the price you see is your full exposure. There are no extra charges at entry, exit, or settlement. The maximum you can put into a single trade is $25,000.
Which deposit methods are allowed?
Underdog Predict accepts only certain methods: debit cards, Apple Pay, and bank transfer via Trustly. Money added through Venmo or credit cards cannot be used for Underdog Predict.
How do withdrawals work?
Withdrawals run through the same process as Underdog’s fantasy side, with a minimum of $10. You can cash out through PayPal or Trustly, and processing typically takes 48 to 72 hours.
