Spreads, Totals, Moneylines, and Parlays, all on Underdog
Starting August. 28, Underdog is rolling out a new offer called “Keep Your Million.” It’s Underdog’s free-to-play survival game, and every eligible customer — all new users, plus most existing users — will receive a virtual $1,000,000 bonus pot to play with.
Football is back on, and so is your chance to instantly call yourself a millionaire… then try and keep it that way. Underdog drops the stash straight into your account with “Keep Your Million.”
Here’s how it works: players pick a question (for example, will Patrick Mahomes throw for higher or lower than 275 passing yards?), then split their million by dragging a slider to divide the pot between Higher and Lower — anywhere from 100% on one side to an even 50/50 split, since all the money has to go somewhere.
Once a pick is submitted before the game starts, it’s locked in and can’t be changed. When the game settles, the player keeps whatever they put on the winning side, and that amount becomes their new pot for the next question. Players make picks across up to 20 questions total, and if they survive all 20, they cash out whatever’s left in Underdog bonus funds. This is a limited-time offer. To get started, use our promo code: BETLSRPM and sign up for a new account today.

The Bonus Funds are credited within 72 hours and, under the current terms, both the original deposit and bonus must be played through 1x within 14 days before the resulting funds can be withdrawn. The offer is for new users only; availability and the maximum bonus vary by state.

Comparison with other prediction markets
Underdog stands out for its focus on sports-based contests and its easy-to-use, fantasy-style interface. While Robinhood and Kalshi offer event contracts tied to financial and political outcomes, Underdog keeps its offerings centered on sports, making the platform straightforward for users interested in sports-focused markets.
For example, compared with Crypto.com, which operates in the broader prediction and crypto space, Underdog offers a more structured, beginner-friendly experience. It may be a good fit for users who prefer a simple mobile interface over more complex trading platforms.

Introduction to Underdog Predict
Founded in 2020 by Jeremy Levine, Brandon Stakenborg, and Trevor John, Underdog quickly emerged as one of the fastest-growing fantasy and prediction platforms in the US. The company modernized the daily fantasy sports experience by combining traditional fantasy competition with streamlined, prediction-based contests, and its signature formats, Best Ball and Pick’em, helped reshape the DFS landscape. Today, Underdog Fantasy is available in around 40 states.
The company attracted backing from high-profile investors, including Mark Cuban, Kevin Durant, and BlackRock, supporting its expansion across multiple US markets. For a time, Underdog looked to expand into traditional sports betting as well, launching a sportsbook in North Carolina in March 2024 with plans to expand to Missouri and elsewhere. The company pivoted, however, partnering with Crypto.com’s derivatives exchange, CDNA, in September 2025 to launch prediction markets, then shutting down its North Carolina sportsbook that December to focus fully on the new business.
That partnership didn’t last long. In March 2026, Underdog acquired Aristotle Exchange DCM and DCO, giving it its own CFTC-registered exchange and clearing organization rather than relying on Crypto.com’s infrastructure. By July 2026, Underdog Predict was running fully on that in-house exchange, a shift CEO Jeremy Levine said would let the company keep more of its trading revenue as it headed into football season.
What is the sports betting industry saying about Underdog?
The industry sees Underdog as a bold innovator in fantasy sports and prediction-style contests. Reports highlight how the brand’s fast-rising formats and growth trajectory reflect wider shifts in gaming and sports entertainment. An analysis by Eilers & Krejcik Gaming described the company as emblematic of “DFS 2.0,” where skill-based contests intersect with event-based outcome markets.
Meanwhile, the status of Underdog’s fantasy product, as well as Underdog Predict and other prediction markets that include sports contracts, may well be affected going forward by evolving legal opinion. Nevertheless, the tone is optimistic about Underdog’s earlier innovations and market potential going forward, tempered by awareness of regulatory complexity and industry disruption.
Underdog website and app experience
The Underdog platform retains its familiar, uncluttered design, with a dedicated Predict tab now positioned alongside Drafts, Pick’em, and Best Ball. Opening Predict brings up a streamlined list of live markets covering sports, politics, economics, and culture. Each market displays a real-time price representing the implied odds of a yes-or-no outcome. Pages load quickly, and the clean layout makes browsing markets feel as straightforward as exploring Underdog’s traditional contests.
The app also makes it easy to switch between its fantasy and trading features without making either side feel disconnected from the rest of the platform. Selecting a market brings up its current price, a simple price-movement chart, and a clearly marked buy button. Compared with platforms such as Kalshi and Polymarket, the experience is more streamlined, with no order book or limit-order functionality. That simplicity could make Predict particularly accessible to existing Underdog users.
Did I like the app?
I liked using the Underdog Predict app more than I expected to. Deposits and withdrawals worked the same as they always have on Underdog, and getting money in or out never took more than a day. My one real complaint is that the app doesn’t give you much context on why a price is moving, so if you want real research behind a trade, you end up leaving the app to find it.
How to create an account on Underdog Predict
Signing up for Underdog takes just a few minutes. The process takes you from registration to your first trade or contest with a few extra steps. Here’s how to get started:
- Visit the Underdog website or download the mobile app. It works on iOS, Android, and most desktop and mobile browsers.
- Tap “Sign Up” at the top of the homepage or on the app’s opening screen.
- Enter your name, email address, date of birth, and a password.
- Verify your location and age. Underdog checks your location to confirm you are in an eligible state and old enough to play, usually 18 or 21, depending on where you live.
- Complete identity verification by providing the last four digits of your SSN or uploading a valid ID.
- Deposit funds using PayPal, a debit card, or Apple Pay, and then you are ready to go.
If you already have an Underdog Fantasy account, you do not need to sign up again for Predict. As long as you are in an eligible state, the Predict tab appears and works right away.
Providing personal info: What’s needed?
To finish verification, you’ll need to provide a valid email address, your residential address, and proof of identity. That usually means the last four digits of your SSN or a government-issued ID. Since Predict now runs on a CFTC-regulated exchange, the identity checks feel a lot closer to what you’d expect from any regulated trading platform, not just a typical fantasy sports app.
Making your first trade on Underdog Predict
Once your account is funded, placing your first trade on Predict takes just a few taps. Here’s how it works step by step:
- Log in and tap the Predict tab at the top of the app.
- Browse markets by category. You can look through sports, politics, economics, or culture, or scroll the main list to see what is trending.
- Open a market you like and check the price. A price of 60 cents on “yes” means the market thinks there is roughly a 60 percent chance that the outcome will happen.
- Choose yes or no and enter how much you want to put in. The app shows your potential payout before you confirm anything.
- Confirm the trade. Once it goes through, the position appears in your portfolio, and the price updates in real time.
- Decide whether to hold or sell early. You can wait for the market to settle on its own, or sell your position back before that happens if the price has moved in your favor.
Underdog event contracts
Underdog’s event contracts on Predict work like a real market rather than a fixed-payout fantasy entry. Each contract represents a yes-or-no outcome, such as whether a team wins a game or inflation comes in above a certain number, and the price moves up and down based on what other traders think will happen.
If you buy a contract at 40 cents and it settles yes, you get a dollar. If it settles no, you get nothing. You are not locked in either way. If the price moves in your favor before the event happens, you can sell your position and take the profit right away instead of waiting for settlement.
This is different from Classic Pick’em, which still exists as a separate product in the app. Pick’em keeps the fixed-payout format you may already know, letting you pick whether a player goes over or under a stat line, like “Victor Wembanyama over 26.5 points.” Predict is the newer, market-style side of things, and the two run alongside each other rather than one replacing the other.
How to place a contract on Underdog Predict
Placing a specific contract on Underdog Predict works the same basic way every time, but here’s how it goes if you already know what you want to trade:
- Use the search bar or filter by category to find the exact market you’re after, whether it’s a game outcome, an election, or something in the culture section.
- Compare the yes and no prices side by side. Whichever side looks underpriced to you is the one you buy.
- Decide how many contracts you want rather than just a flat dollar amount. Each contract costs whatever the current price is, plus a small trading fee of about 2 cents per contract.
- Confirm the trade, and it shows up right away in your open positions.
- Keep an eye on the price as the event gets closer, and sell your contracts back whenever you want if you’d rather lock in a gain or cut a loss instead of waiting for it to settle.
Differences between Underdog and competitors
Underdog once stood apart from Robinhood, Kalshi, and Crypto.com by focusing exclusively on sports. That distinction has largely disappeared. Underdog Predict now covers sports, politics, economics, and culture, putting its category lineup much closer to what you’ll find on Kalshi than many users might expect.
Where Underdog still stands out is simplicity. Kalshi and Polymarket offer order books, limit orders, and greater market depth for users who want a more traditional trading experience. Predict strips much of that complexity away, allowing users to buy contracts at the current price. That makes it particularly approachable for anyone coming from a fantasy sports background who doesn’t want to learn a new trading interface.
Crypto.com falls somewhere in between. It offers substantial market depth across crypto and other categories, but that functionality is part of a much larger crypto exchange that can feel overwhelming if you’re only interested in trading a few event contracts. Underdog’s advantage remains its familiarity and accessibility, particularly for sports fans who already use the app—even though Predict is no longer limited to sports.
Sports selection at Underdog
The sports selection looks a little different depending on which side of the app you’re using. Pick’em and Best Ball still cover a huge range, from the NFL, NBA, MLB, and NHL down to college football and basketball, golf, MMA, boxing, NASCAR, and esports. If you want player props across a long list of sports, that side of Underdog hasn’t changed much.
Underdog Predict’s sports markets are narrower for now. You’ll mostly find contracts tied to the NFL, NBA, NHL, MLB, soccer, tennis, and basketball, built around things like game winners and series outcomes rather than individual player stat lines. It’s a smaller list than what Kalshi or Polymarket offer on the sports side, and a lot smaller than Pick’em’s own prop catalog, but it will probably grow as Underdog keeps building out the new exchange.
What could be added?
Predict could benefit from expanding beyond sports, particularly by adding more markets focused on economics and culture. It could also introduce basic trading features, such as limit orders, that are already available on platforms like Kalshi and Polymarket. On the sports side, expanding into leagues such as cricket, rugby, and additional soccer competitions would help Predict better compete with the broader range of options available through Pick’em.
Tips and strategies for traders
Trading well on Underdog Predict comes down to reading prices correctly and not getting irrationally attached to a position. A price of 70 cents on “yes” means the market already thinks that outcome is likely, so the real question is whether you think the true odds are actually higher or lower than that.
Watch for markets where the price seems off from what you’d expect based on the news or the matchup. Those small gaps are where you actually make money, rather than just picking whatever team or outcome you personally like.
Don’t feel like you have to hold every contract until it settles. If a price moves in your favor early, there’s nothing wrong with selling and locking in the gain instead of waiting around and hoping it holds. The same goes in reverse if a position starts going against you.
It also helps to spread your trades across a few categories rather than putting everything into one sport or event. Sports markets can be noisy and swing hard on a single injury report, while things like politics or economics tend to move more slowly and give you more time to think. And keep the small per-contract fee in mind, since it adds up if you’re making many small trades.
Underdog customer support
Underdog keeps customer support simple and accessible. You can reach the team through live chat in the app or on the website, by email, or via social media on X. There is also a detailed Help Center with FAQs covering the most common topics, including deposits, withdrawals, contract and contest rules, and account verification.
In testing, response times were solid, with most questions answered within a few hours. The support team came across as friendly and knowledgeable, handling both basic and more technical questions about Predict without issue.
Security and safety
Underdog takes security seriously on both the app’s front and back ends. Accounts use encryption, two-factor authentication, and biometric logins, and personal data is handled the way you’d expect from any regulated finance app at this point.
The bigger change is on the regulatory side. Predict runs on its own CFTC-registered exchange and clearing organization, built from the Aristotle Exchange acquisition earlier in 2026, so trades on Predict are overseen at the federal level rather than falling under state fantasy sports rules. Classic Pick’em and Best Ball still operate under the older state-level fantasy sports framework, so the two products actually sit under different regulatory umbrellas even though they live in the same app.
Underdog also keeps customer funds separate from its operating accounts and offers the usual responsible gaming tools, such as deposit limits, session timeouts, and self-exclusion. Altogether, it feels like a platform that takes both money and compliance seriously, on the fantasy and trading sides.
My verdict on Underdog Predict
Underdog Predict is a legit, well-built entry point to prediction markets, but it’s still finding its footing as a standalone product. The category spans sports, politics, economics, and culture. It holds up well against Kalshi, and having its own CFTC-registered exchange gives it real staying power rather than just renting infrastructure from someone else.
What it does have going for it is the same simple, mobile-first feel that made Pick’em and Best Ball popular in the first place, making it an easy entry point if you’re already using Underdog and are curious about prediction markets.
Underdog Predict FAQ
Yes. You can log into your Underdog account from any device, including desktop, iOS, or Android, and everything syncs automatically in real time.
It depends on the market. A sports contract usually settles within 30 minutes after the game ends. Still, one tied to politics, economics, or culture can take days, weeks, or even months to settle, since it only does so when the real-world event it’s tracking actually happens.
Deposits and withdrawals are free, but Predict does charge a small trading fee of about 2 cents per contract on both buys and sells. There’s also a $4 monthly inactivity fee if you haven’t used your account in 18 months, so it’s not entirely fee-free like the rest of the app.
Of course! You can hold as many open positions as you want across different markets, and each one settles and pays out on its own.
