Best Kalshi Markets to Trade Tonight (Mar. 17)
March Madness officially tips off tonight with two First Four games from UD Arena in Dayton, Ohio. Add an eight-game NBA slate and the World Baseball Classic Final, and Kalshi's sports board is loaded with tradable contracts for new users looking to put the BOOKIES bonus to work immediately.
March Madness First Four - Dayton, Ohio
No. 16 UMBC vs. No. 16 Howard — 6:40 p.m. ET on truTV
The winner advances to face No. 1 seed Michigan in the first round. UMBC is back in the NCAA Tournament for the first time since its historic 2018 upset of No. 1 Virginia — the first 16-over-1 victory in tournament history. Howard, meanwhile, is making its second straight appearance out of the MEAC. ESPN's Jay Bilas doesn't give either team much of a chance against Michigan, but the First Four game itself could be tightly contested. Look for Kalshi to offer contracts on the outright winner and total points.
No. 11 Texas vs. No. 11 NC State — 9:15 p.m. ET on truTV
A higher-stakes matchup between two Power conference programs battling for a spot in the Round of 64. Texas brings size and scoring punch through guard Dailyn Swain, while NC State is looking to recreate some of its recent March magic. Sean Miller's Longhorns are the slight favorites. The winner likely faces Purdue or Gonzaga depending on the bracket path. Kalshi's game-level markets — including moneyline-style win contracts and margin-of-victory positions — are available for both First Four games.
Kalshi Billion Dollar Bracket: Enter With Promo Code BOOKIES
Kalshi is also running its Billion Dollar Bracket contest for the 2026 NCAA Tournament, giving users the chance to win up to $1 billion by correctly predicting every game in the bracket. New users who sign up with promo code BOOKIES and claim the $10 bonus can enter the contest immediately after funding their account. The First Four tips off tonight from Dayton, Ohio, making this the last window to register and lock in bracket picks before the Round of 64 begins Thursday.
NBA Tuesday Night (8 Games)
Cleveland Cavaliers at Milwaukee Bucks — 7:30 p.m. ET (NBC)
The final regular-season meeting between Central Division rivals. Milwaukee is coming off a 134-123 win over Indiana powered by 31 points from Giannis Antetokounmpo, though both Giannis and Myles Turner are listed as questionable for tonight. Cleveland dropped a 130-120 decision to Dallas on Sunday but remains atop the East. Donovan Mitchell has averaged 32.8 PPG against divisional opponents this season. Kalshi contracts include the Cavaliers-Bucks over/under at 227.5 total points, priced near $0.53 per share on the over.
Minnesota Timberwolves vs. Phoenix Suns — 8:00 p.m. ET
A Western Conference play-in battle with major seeding implications. Just four games separate third from seventh in the West. Anthony Edwards (knee) is confirmed out for the Timberwolves, but the Suns are also down two starters (Dillon Brooks and Mark Williams). Minnesota's win contract is priced around $0.59 per share on Kalshi, reflecting a lean toward the home team despite Edwards' absence.
Denver Nuggets vs. Philadelphia 76ers — 10:00 p.m. ET
Denver has two full days of rest while Philly is playing its third game in four nights. The 76ers are without Joel Embiid (oblique), Tyrese Maxey (finger), and Kelly Oubre Jr. (elbow) — all confirmed out. Kalshi offers a margin-of-victory contract at Nuggets -13.5, priced around $0.57 per share.
Other NBA games tonight: Detroit Pistons at Washington Wizards (DET -19.5), Miami Heat at Charlotte Hornets (CHA -5.5), Oklahoma City Thunder at Orlando Magic (OKC -10.5), Indiana Pacers at New York Knicks, San Antonio Spurs at Sacramento Kings.
World Baseball Classic Final - USA vs. Venezuela
8:00 p.m. ET on FOX — loanDepot Park, Miami
Team USA faces Venezuela in the WBC championship game, its third straight trip to the final. The U.S. beat the Dominican Republic 2-1 in the semis, while Venezuela rallied to defeat defending champion Italy 4-2. Venezuela's Maikel Garcia leads the tournament in hits with a .435 batting average and 1.110 OPS. Eduardo Rodriguez takes the mound for Venezuela against Mets prospect Nolan McLean for the USA. Yankees captain Aaron Judge called the WBC atmosphere "bigger and better than the World Series." Kalshi offers contracts on the outright winner and game-related outcomes for the WBC Final.
