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.
• Alternative Prediction Market Promos:
  • The Kalshi referral code "DIMERS" has been extended through May 2026, unlocking a popular $10 prediction market bonus.
  • The new Polymarklet promo code "DIMERS" is now live as well, unlocking $20 for new users.

Tuesday Underdog UCL, 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 UEFA Champions League

The Champions League brings premier European action to the afternoon board. Please note that for these soccer markets, the outcome is based on 90 minutes plus stoppage time (does not include extra time or penalties).

• Arsenal vs. Atletico Madrid (3:00 PM ET): Prediction markets are seeing massive volume today—over $1.37 million traded—favoring the Gunners. Arsenal holds a 60% probability (60¢) of winning the match outright, while Atletico Madrid sits at an 18% probability (18¢), and a Tie is priced at 24% (24¢). If you are trading goal totals, Over 2.5 goals is slightly favored at 51% (51¢) versus the Under at 49% (50¢). Alternatively, you can back Arsenal to win by over 1.5 goals on the spread at a 36% probability (36¢).

Tuesday NBA Playoffs (Round 2)

The basketball slate features two games with teams laying points to advance in the second round.

• Cleveland Cavaliers vs. Detroit Pistons (7:00 PM ET): The Pistons enter Tuesday as slight -2.5 point favorites. You can buy contracts on whether Detroit will cover that spread (priced at a 61% probability), or if the Cavaliers can pull off the upset or keep it within a bucket.
• Los Angeles Lakers vs. Oklahoma City Thunder (8:30 PM ET): The Thunder are massive home favorites, laying -15.5 against the Lakers. Dimers' model gives Oklahoma City an overwhelming 88% win probability — the most lopsided playoff matchup on tonight's board.

Tuesday NHL Playoffs (Round 2)

The ice slate offers a prime moneyline trading opportunity this evening.

• Minnesota Wild vs. Colorado Avalanche (8:00 PM ET): Colorado holds a strong home edge at -187 on the moneyline against the Wild at +184. Dimers projects a 62% win probability for the Avalanche to secure the victory tonight.
