How Underdog Predict Works

Underdog Predict runs on an event-contract model, similar to platforms like Kalshi and Polymarket. Instead of betting against a traditional sportsbook vigorish, traders buy binary contracts on whether a specific outcome will occur.

The Mechanics

• Price Range: Every contract trades at a price between $0.01 and $0.99, reflecting the market probability of the outcome.

• Settlement Values: If the event occurs, the contract settles at $1.00. If the event does not occur, the contract settles at $0.00.

• Profit Calculation: Your payout is the difference between your purchase price and the $1.00 settlement value.

Worked Example

Suppose you are trading on the Guardians vs. Red Sox game:

1. You look at the market: "Will the Cleveland Guardians win the game?"

2. The market price for "Yes" is $0.60 per contract.

3. You buy 10 contracts at $0.60 each (total outlay = $6.00).

4. Outcome A (Guardians Win): Each contract settles at $1.00. You receive $10.00 total, yielding a net profit of $4.00.

5. Outcome B (Guardians Lose): Each contract settles at $0.00. You lose your initial $6.00 trade.

You can also sell contracts prior to game completion to lock in profits or minimize losses as live game momentum shifts.
