First Four Predictions via Kalshi
The First Four kicks off with Prairie View A&M vs. Lehigh and Miami (OH) vs. SMU, and our expert picks highlight Prairie View A&M +2.5 and Over 164.5 in Miami (OH) vs. SMU as top opportunities. Lehigh and SMU remain safer bets, but traders can use the Kalshi promo code ACTION to test both longshot and safer predictions in these college basketball matchups. Traders can also download a printable March Madness bracket to track the First Four matchups and the main tournament while using the Kalshi promo code ACTION to test their predictions.
Prairie View A&M vs. Lehigh Expert Pick: Prairie View A&M +2.5 (47%): Prairie View A&M and Lehigh enter the First Four on strong runs, with the Panthers fueled by improved health and elite defensive intensity, while the Mountain Hawks rely on dominant post scoring from Hank Alvey and dynamic perimeter play from Nasir Whitlock. Despite Lehigh’s offensive firepower, Prairie View’s full roster, defensive versatility, and momentum make them the team to back in Dayton.
Miami (OH) vs. SMU Expert Pick: Over 164.5 Points (47%): Miami (OH) enters the NCAA Tournament as a confident, mentally tough 31-1 mid-major, relying on sharpshooting and half-court execution to compete against stronger teams. SMU’s superior athleticism, speed, and inside scoring, however, likely gives them the edge, making a high-scoring, fast-paced game—and the over—the most probable outcome.
Champions League Matches to Trade
In the Champions League, Bayern Munich vs. Atalanta, Liverpool vs. Galatasaray, and Tottenham vs. Atlético Madrid offer prime opportunities to trade in real-time prediction markets. Our expert pick favors Bayern Munich to continue their dominant run, while Liverpool and Tottenham present safer or balanced trades. New users can use the Kalshi promo code ACTION or Kalshi referral code ACTION to follow these picks on one of the best prediction market apps.
Bayern Munich vs. Atalanta Expert Pick: Bayern Munich (73%): After a 6-1 first-leg rout, Bayern Munich is poised to secure the tie at home, continuing a dominant Champions League run highlighted by prolific scoring and consistent offensive firepower. With Atalanta focused on Serie A and recent defensive lapses, Bayern’s attack should shine again, making a home win highly likely.
