How Underdog Predict Works

Underdog Predict operates as a financial prediction market using binary event contracts rather than fixed odds or point spreads. Every market asks a simple "Yes/No" question about a sports event.

Market Mechanics

• Contract Value: Every contract is priced between $0.01 and $0.99 prior to or during the game based on market probability.

• Settlement: When the game ends, the contract settles at either $1.00 if the event occurs (YES), or $0.00 if it does not (NO).

• Profit: Your potential profit equals $1.00 minus your purchase price per contract.

Worked Example:

Suppose you want to trade on whether the Washington Mystics will score over 80.5 points against the Sky.

• You buy a "YES" contract priced at $0.60.

• If the Mystics score 81 or more points, the contract settles at $1.00, netting you a $0.40 profit per contract ($1.00 payout - $0.60 purchase price).

• If the Mystics score 80 or fewer points, the contract settles at $0.00, resulting in a loss of your $0.60 purchase price.

Chicago Sky vs. Washington Mystics - Markets to Watch
