How Underdog Predict Works

Underdog Predict functions as a regulated prediction market where users buy and sell financial event contracts tied to real-world sporting outcomes. Instead of traditional American odds (e.g., -110 or +150), prices are represented as dollar values between $0.01 and $0.99, directly reflecting the market's implied probability.

Event Contract Settlement Rules:

• Every contract pays out $1.00 if the specified event occurs.

• Every contract pays out $0.00 if the event does not occur.

Worked Example

Suppose you are looking at an event contract for the Boston Celtics to win the game outright.

1. Buy In: Market demand sets the current "Yes" contract price at $0.60 (implying a 60% probability).

2. Execution: You purchase 100 "Yes" contracts at $0.60 each, for a total cost of $60.00.

3. Settlement if Boston wins: The contracts settle at $1.00 each. Your 100 contracts return $100.00, generating a net profit of $40.00 ($100 payout minus your $60 purchase price).

4. Settlement if Philadelphia wins: The contracts settle at $0.00. Your return is $0.00, resulting in a loss of your initial $60 purchase.

You also have the flexibility to sell your contracts back to the market prior to game completion to lock in profits or cut potential losses as real-time momentum shifts.

76ers vs. Celtics - Markets to Watch

When trading the October 10, 2026 clash between Philadelphia and Boston at TD Garden, several core event-contract categories offer key trading opportunities:

• Buy "Yes" or "No" positions on whether Boston will defend home court or if Philadelphia will secure the road victory.

• A high-velocity market settling within the opening minutes of the first quarter based on which squad lands the initial basket.

• Predict whether the combined final score will cross key benchmark point thresholds.

• Short-duration contracts focusing specifically on lead status or point totals at the end of the 1st quarter or 1st half.

• Individual event contracts tied to key player milestones, such as whether a starter achieves a specific threshold in points, rebounds, or assists.

Is Underdog Predict Legal in Your State?

Yes. Underdog Predict operates as a federally compliant prediction market exchange. Because event-contract trading is governed under financial regulatory frameworks rather than state-by-state sports betting legislation, it is legal in significantly more jurisdictions than traditional online sportsbooks.

Underdog Predict is available in 46 U.S. States plus Washington D.C.

Excluded Jurisdictions

Underdog Predict is available nationwide except in the following four states:

• Arizona

• Michigan

• Nevada

• New York

If you reside in any of the other 46 states or Washington D.C., you can legally register, deposit, and trade event contracts using Underdog promo code WSNPLAY.

Responsible Risk Management

While event contracts offer a regulated financial framework for sports forecasting, trading involves financial risk. Manage your risk responsibly with these core principles:

• Only trade funds you are fully prepared to lose. Establish weekly or monthly deposit limits before placing orders.

• Avoid allocating your entire account balance to a single event contract or game outcome.

• Ensure you understand the exact settlement rules and conditions for every market before opening a position.

• Underdog Predict provides account tools to set trading limits, take timeouts, or self-exclude if trading ceases to be safe or enjoyable.
