Underdog has already built a strong reputation in daily fantasy sports, and now the company is stepping into a new kind of sports gaming experience: tradeable event contracts.

This new product, known as Underdog Predict, gives players a different way to engage with sports outcomes. Instead of placing a traditional bet or building a fantasy lineup, users can buy and sell Yes/No contracts tied to real game events, player performances, or season-long futures.

Underdog Predict is powered through a partnership with Crypto.com | Derivatives North America (CDNA). CDNA provides the underlying event contracts, while Underdog delivers them inside its familiar mobile app experience. CDNA is regulated by the Commodity Futures Trading Commission (CFTC), which theoretically allows the platform to operate nationwide, including in states where sports betting is not legal.

At launch, Underdog Predict is currently live in 27 states.

So what does it feel like to actually use Underdog Predict, and what should players know before jumping in? Let’s walk through the experience.

Underdog Predict promo code & welcome bonus

One of the first things new users ask is whether Underdog Predict comes with a sign-up bonus.

Because Underdog’s fantasy contests and prediction-style products all live inside the same app, the current welcome offer can be used across all products on the platform. That means you can use this offer with predictions, Pick’Em, and Draft.

Underdog Predict Promo Code: PLAYUSAPM

New users who sign up for a new account with promo code PLAYUSAPM can unlock the following offer:

  • Keep Your $1,000,000 in Bonus Funds
  • Plus 50% First-Time Deposit Match up to $1,000 (State-Dependent)

Starting Aug. 28, Underdog is giving players a million-dollar bankroll — with one catch: you have to keep it.

The new “Keep Your Million” promotion is a free-to-play survival game available to all eligible new customers and most existing users. Underdog drops a virtual $1 million bonus pot into your account, then puts you in control of how much survives from one question to the next.

How does Keep Your Million work?

The concept is simple: make a pick, split your money and try not to lose it.

Players start by choosing a question tied to an upcoming game. For example, you might be asked whether Patrick Mahomes will finish with higher or lower than 275 passing yards.

You then use a slider to divide your million-dollar pot between the Higher and Lower outcomes. You can put as much as 100% on one side, but every dollar has to be allocated, meaning you can also split the pot 50/50.

Once you submit your selection before the game begins, your allocation is locked. After the game settles, whatever you placed on the winning outcome becomes your new pot. From there, you move on to the next question and try to protect what’s left.

You can play through up to 20 questions, with each correct result carrying your remaining pot forward. Make it through all 20 and whatever survives can be cashed out as Underdog bonus funds.

“Keep Your Million” is available for a limited time, so eligible players can get started by using promo code PLAYUSAPM when signing up for a new Underdog account.

This bonus applies to Underdog’s Fantasy ecosystem, including Team Picks, which is the format Underdog emphasizes most heavily in its prediction-style experience.

Since Predict and Fantasy share the same platform, it’s a seamless way for players to explore the app’s newer contract-style markets while still benefiting from Underdog’s core entry bonuses.

There’s a $1,000 bonus on the table, too

The million-dollar game isn’t the only incentive for new Underdog users. Eligible first-time depositors can also grab a 50% Deposit Match worth up to $1,000 in Bonus Funds.

Getting started requires a minimum $10 deposit, with Underdog matching 50% of the amount deposited. Want the full $1,000 bonus? You’ll need to deposit $2,000.

Once you qualify, the Bonus Funds are credited within 72 hours. There is a catch, though: under the current terms, both your original deposit and bonus must be played through 1x within 14 days before any resulting funds are eligible for withdrawal.

This promotion is for new users only, and the available offer — including the maximum bonus — varies by state. Here’s how Underdog’s current offers break down by state group:

States with JUST Predictions offer (Keep Your Milly only): CT, HI, ID, IA, LA, ME, MT, WA

States with Pick’Em and Predictions offer (Keep Your Milly + 50% Deposit Match up to $1,000 in Bonus Funds): AL, AK, AR, CA, DE, DC, FL, GA, IL, IN, KS, MN, MO, NE, NH, NM, NC, ND, OK, OR, RI, SC, SD, TX, UT, VT, VA, WV, WI, WY

What is Underdog Predict?

Underdog Predict is Underdog’s entry into sports-based prediction markets, and it may appear under the name Team Picks in states where the product is available.

The concept is simple: players can trade contracts based on future sports outcomes, such as:

  • Will Team X beat Team Y?
  • Will a player score 20+ points?
  • Will a team make the playoffs?

Instead of betting against a sportsbook, you’re participating in a market where each outcome is represented by a contract priced between $0.01 and $0.99.

If a contract is priced at $0.75, that reflects a 75% implied probability.

Players choose Yes or No, buy positions, and can potentially sell those positions later if the market shifts.

Underdog team picks example

What Does an Event Contract Look Like in the App?

Underdog event contracts are presented as straightforward questions, making them approachable even for users new to prediction markets.

  • For example: “Will Seattle win Super Bowl 2026?”

You pick Yes or No, then decide how much you want to invest at the current contract price.

This structure makes Underdog Predict feel less like betting and more like trading a sports opinion in real time.

Real-Time Pricing: The Trading Element Players Notice Most

One of the biggest differences between Underdog Predict and online sportsbooks is that pricing is dynamic.

Contract prices move throughout the day based on market activity, breaking news, injuries, and overall demand.

That creates opportunities for players to:

  • Buy low when prices drop

  • Sell high before an event ends

  • Exit early to limit losses

It’s a format that rewards users who stay plugged into sports news and like a more interactive style of play.

How Contracts Settle (Win or Lose)

When an event ends, contracts settle in a simple way:

  • Winning contracts settle at $1

  • Losing contracts settle at $0

Profit is calculated as:

  • ($1 – purchase price) × number of contracts

Because losing positions become worthless, players should approach markets carefully and manage risk responsibly.

Who Is Underdog Predict Best For?

Underdog Predict is built for sports fans who want something more flexible than static parlays or traditional betting lines.

It’s especially appealing for:

  • DFS players already using Underdog
  • Sports bettors curious about market-style trading
  • Fans who enjoy reacting to live news and shifting odds

Users must be at least 18+ (or 19/21 depending on the state). Players who want to trade on events outside of sports would be better suited at Kalshi or Fanatics Markets.

MLB icon

College Football icon

Users can engage with prediction markets on college football matchups, buying and selling contracts on outcomes across major games, tapping into dynamic pricing that updates through the event.

College Basketball icon

College Basketball

While less prominent than pro sports, Underdog’s prediction offerings cover college basketball outcomes too, allowing fans to trade on game results with market-based probabilities rather than static lines.

You can also find a few events based on other major American and international sports like soccer, MMA, golf, and boxing. The events can cover a wide range of scenarios and outcomes, such as:

  • Game outcomes
  • Playoff advancement
  • Seasonal outcomes
  • Player statistics

Notably, other prediction markets like Kalshi and Polymarket cover a wider range of events. Standard categories, besides sports, include politics, technology, entertainment, financials, economics, the weather, and more. However, Underdog Predict focuses solely on sports events, which aligns with its core business model, seeing as it is one of the biggest fantasy and sports betting platforms in the U.S.

Pros of using Underdog prediction markets

There are many advantages to using Underdog Predict, most notably:

  • Everything is built around sports outcomes, making it cleaner than broader prediction platforms.
  • Players can enter and exit positions like an exchange rather than being locked into final bets.
  • CDNA provides the regulated contract structure behind the scenes.
  • Underdog’s app design is polished, familiar, and easy for DFS users to navigate.
  • All trading is done in USD, lowering the learning curve compared to crypto-based markets.
  • Underdog Predict may confuse some users looking for a standalone prediction app. These picks are embedded in Underdog's fantasy platform.
  • Underdog Predict will not be a great fit if you want to make predictions on culture, crypto, or the weather.
