Understanding Underdog Prediction Markets and Underdog Picks:

Underdog gives sports fans a completely different way to interact with the board. Instead of dealing with confusing sportsbook odds, Underdog treats team outcomes like tradeable commodities, while maintaining its famous fantasy Pick'em format.

• Underdog Picks (Fantasy): This is the classic player-driven experience. You select two or more players from opposing teams and pick "Higher" or "Lower" on projected statistics like points, assists, goals, or saves.
• Underdog Prediction Markets (Team Outcomes): Every prediction contract is priced between $0.01 and $0.99, representing the real-time probability of that outcome hitting. You can trade on standard markets like which team will win outright (Moneyline) or who will cover the margin of victory (Spread). A winning contract always pays out a flat $1.00.

Tuesday Night Underdog NBA & NHL Guide:

Using the Underdog promo code DIMERS gives you the capital to take positions on a massive, multi-sport playoff card today.

Tuesday NBA Playoffs

The basketball slate features three games with teams laying heavy numbers.

• Philadelphia 76ers vs. Boston Celtics (7:00 PM ET): The Celtics enter Tuesday as -11.5 point favorites. You can buy contracts on whether Boston will cover that spread, or if the 76ers can keep it closer than the market expects.
• Atlanta Hawks vs. New York Knicks (8:00 PM ET): The Knicks are priced as -6.5 favorites at home against Atlanta. You can pair a prediction on the spread with fantasy picks on the game's key contributors.
• Portland Trail Blazers vs. San Antonio Spurs (9:30 PM ET): The Spurs are massive home favorites at -11.5 against Portland. Dimers' model gives San Antonio an 83% win probability — the most lopsided playoff matchup on tonight's board.

Tuesday NHL Playoffs

The ice slate offers three moneyline trading opportunities spread across the evening.

• Boston Bruins vs. Buffalo Sabres (7:30 PM ET): The Sabres hold a modest home edge at -159 on the moneyline against the Bruins at +150. Dimers projects a 60% win probability for Buffalo.
• Minnesota Wild vs. Dallas Stars (8:00 PM ET): Dallas is a narrow -125 favorite on the road at Minnesota, with Dimers giving the Stars a 54% win probability — the tightest call on the NHL slate tonight.
• Anaheim Ducks vs. Edmonton Oilers (10:00 PM ET): Edmonton is the heaviest hockey favorite of the night at -162 on the moneyline against the Ducks, who offer +148 value. Dimers projects a 60% win probability for the Oilers.
