What Is Keep Your Million?

Keep Your Million is Underdog’s free-to-play survival game.

1. Pick a question – for example, whether a quarterback in this matchup finishes higher or lower than a stated passing-yardage number.
2. Split your million – drag the slider to divide a virtual $1,000,000 pot of bonus funds between Higher and Lower; all of it must be allocated.
3. Lock it in – submissions are final once the game starts and cannot be changed.
4. Keep your winnings – when the question settles, you keep whatever was allocated to the winning side, and that becomes your pot for the next question.
5. Run it back – continue through up to 20 questions and survive all 20 to cash out whatever remains in Underdog bonus funds.

All new users and most existing users are eligible for Keep Your Million, while the 50% deposit match is for eligible new users only who meet the age requirement and live in a participating state.

How Does Underdog Predict Work?

Underdog Predict is a prediction-market exchange, not a sportsbook. We have a few important distinctions to go through.

Underdog Predict (also known as UDX at underdogexchange.com) operates on an exchange model where users buy or sell contracts tied to a real-world NFL outcome. Each contract’s market price directly reflects the implied probability of that outcome occurring. These prices move dynamically as other participants trade, and positions can be held until the event officially settles.

Because it is an exchange, there is no house taking the other side of your position; you trade entirely against other market participants. UDX operates as a regulated venue subject to CFTC regulatory oversight rather than under state gaming licenses. Trading involves risk, including total loss on positions, and nothing on the platform constitutes a recommendation, solicitation, or offer to buy or sell any financial instrument.

Where Can You Trade With Underdog Predict?

Availability is limited to participating states where UDX operates, and eligible users must also meet the minimum age requirement.

While the platform is accessible in many jurisdictions, some states are entirely excluded. The definitive, current list of participating and excluded states is shown during the sign-up process and on underdogexchange.com, so users should always confirm their eligibility there before making a deposit.

The regulatory status of prediction markets is being actively contested in some states. Because legal challenges and regulatory reviews remain ongoing, state availability for Underdog Predict can change at short notice.
