Underdog is the newest addition to the rapidly growing prediction-market space, makes Underdog the first major US fantasy gaming operator to move into event-based contract trading. Long known as one of the top DFS operators in North America, Underdog is now expanding beyond daily fantasy sports and giving users a way to trade on team and player outcomes directly inside the Underdog app.

Using infrastructure from Crypto.com’s CFTC-regulated derivatives exchange, Underdog brings market-style trading into the sports world. Users can buy and sell event contracts with prices that move as other traders react, creating a dynamic marketplace for team and player outcomes.

Because the product is still rolling out, Underdog has not yet released an official Underdog prediction market promo code. RotoGrinders will update this page immediately when the first Predict-specific bonus or code becomes available.

Underdog Prediction Market Promo Code Overview

At this time, Underdog has not released a dedicated Underdog Prediction Market promo code, and no specific welcome offer has been announced for the prediction-market product.

When a code becomes available, new users can create an account in the Underdog app and complete the identity verification process. During signup, you’ll provide your name, address, phone number, a secure password, and the last four digits of your SSN to confirm your identity.

Once verified, you can use any eligible bonus funds in the app and may be able to participate in prediction markets, as long as you are located in a state where Underdog is currently available.

Stay tuned, this page will be updated the moment an official Underdog prediction market promo code or welcome offer is announced.

What Is Underdog’s Prediction Market?

Underdog’s prediction market is Underdog’s new sports event–contract exchange, built directly into the Underdog app.

Users can buy or sell event contracts tied to real-world outcomes, similar to taking positions in a financial market. Each contract represents a “Yes” or “No” answer to a specific sports outcome, like “Will the Eagles repeat as Super Bowl champions” or “Will Josh Allen win NFL MVP?”, and its price moves based on how the market trades.

Users buy in at the current contract price, which rises or falls depending on market sentiment. Riskier predictions cost less, while popular or more likely outcomes cost more. Traders can also choose to sell their position before the market settles, either to lock in a profit or limit potential losses.

When the event settles, users holding the correct outcome are paid out $1 per winning contract, with profits determined by the original purchase price. Those on the losing side receive nothing, mirroring how positions work in a traditional prediction market rather than in a sportsbook.

How Underdog’s Prediction Market Team Picks Work

Team Picks allow users to trade contracts on team-level outcomes, like predicting whether the 49ers will win the NFC Championship or if the Lakers will score 110+ points. Instead of placing a traditional wager, users buy or sell “Yes” or “No” event contracts tied to these real-world outcomes, with prices moving as the market trades.

Player Picks and Totals

Underdog also lets users trade contracts on individual player performances, such as Josh Allen total passing yards, how many touchdowns Dak Prescott will throw, or how many points LeBron James will score in a game. Instead of betting on fixed lines, users buy or sell contracts tied to these stat-based outcomes, and pricing adjusts dynamically based on market sentiment.

Inside the Underdog and Crypto.com Partnership

Underdog has partnered with Crypto.com to bring prediction markets to their users, marking the company’s first expansion beyond daily fantasy sports and into CFTC-regulated sports event contracts. Through this collaboration, Underdog Predict will be available in 31 US states within the existing Underdog app, giving users a new way to trade on sports outcomes.

Underdog and Crypto.com clearly identified prediction markets as the future of the evolving gaming landscape, not only in the US, but around the world. Prediction markets have proven lucrative, with platforms like Kalshi, Robinhood, and Polymarket gaining significant traction.

In this partnership, Underdog manages the consumer-facing experience—including the app interface, product design, and sports audience—while the event contracts themselves are listed and settled through Crypto.com | Derivatives North America (CDNA), a CFTC-regulated exchange.

Because Underdog operates through a CFTC-regulated derivatives exchange, it falls under federal event-contract regulations rather than state sports betting laws. This structure allows Underdog to offer Underdog’s prediction amrkets in 31 states while remaining fully compliant with CFTC oversight.

How the Underdog and Crypto.com Partnership Works

As mentioned, Underdog will provide the client base and front-end experience for its new prediction-markets platform, while Crypto.com powers the regulated exchange infrastructure behind it. Underdog leverages Crypto.com’s expertise operating a federally regulated derivatives exchange, and Crypto.com benefits from Underdog’s established presence in the sports gaming space.

Together, Underdog and Crypto.com work hand-in-hand to make Predict possible. Underdog delivers the interface, app integration, and customer access, while Crypto.com handles the listing, clearing, and settlement of the contracts under federal oversight.

How Underdog’s Prediction Market Differs From Traditional Sports Betting

Underdog offers a very different experience from traditional sports betting at US sportsbooks. Instead of placing bets against the house, users trade event contracts against other market participants. The house does not set the odds, contract prices move based on supply and demand within the market.

With Underdog, users purchase contracts, similar to stocks, picking the outcomes of sporting events with a simple “Yes” or “No” answer. The more popular or likely the outcome appears, the higher the contract price. Riskier or less popular predictions typically cost less.

All Underdog contracts trade between $0.01 and $1.00, with the value fluctuating as the market reacts to new information and trading activity.

Prediction Markets Explained

Prediction markets operate similar to stock markets with purchased “contracts” or stocks on the outcome of certain real-world events like sports. You can purchase a contract for between $0.01 and $1.00 on either side of a host of “Yes” or “No” outcomes for questions like “Will Team A win?” or “Will the total go over 45 points?”

With prediction markets, you buy in at the posted rate and can sell, even before the event settles (is over), in order to gain a small profit or to minimize loss. Once the event settles, those on the right side of the outcome will be paid out $1 per contract. Those on the wrong side go to $0.

Key Features of the Underdog App

As a wing of the highly regarded Underdog DFS platform, Underdog’s prediction market delivers a nice set of key features that not only strengthen the prediction markets brand, but also make its overall trading experience unique and a true pleasure.

Real-Time Market Movement

Just like stock markets, Underdog’s event-contract prices fluctuate based on public sentiment, trading activity, trends, and real-time sports results. As users buy and sell contracts, the market reacts immediately, and pricing adjusts to reflect the most current information. This creates a dynamic environment where users can track movement and respond as conditions change.

User Interface and Accessibility

As one of the top DFS operators in the industry, it’s not a surprise that Underdog features an impressive, simple, modern and intuitive interface for users. The app is extremely well laid out, is user-friendly and perhaps most importantly, approachable and accessible for both casual participants and experienced market users.
