The Kalshi referral code for April 2026 is BOOKIES. New users who sign up, deposit as little as $1, and complete $10 in total trades receive a $10 bonus credited automatically. The offer works across every available Kalshi market, including tonight’s NBA Play-In Tournament games, the full MLB slate, politics, economics, and more. Kalshi is a federally regulated prediction exchange overseen by the CFTC, not a state-licensed sportsbook, which means it operates in 40+ states including California, Texas, Florida, and Georgia.

Kalshi Markets to Trade Today: NBA Play-In Tournament and MLB (April 15)

The NBA Play-In Tournament continues tonight with two pivotal games. Last night, the Hornets edged the Heat 127-126 in overtime, and the Trail Blazers stunned the Suns 114-110 to clinch the No. 7 seed in the West. Tonight’s winners secure playoff berths—and you can use your $10 bonus from the BOOKIES referral code on any of these markets.

Magic at 76ers: 7:30 PM ET (Play-In 7/8 Game, Prime Video)

Philadelphia is a 1.5-point home favorite at approximately -132 on the moneyline. Joel Embiid remains sidelined, which elevates Tyrese Maxey as the primary scorer (28.3 PPG in Embiid’s absence). Orlando’s Paolo Banchero has a clear size advantage, he hung 32 points on 10-of-18 shooting the last time he played at Philly without Embiid. The winner locks in the No. 7 seed; the loser hosts Charlotte on Friday for the final playoff spot.

Warriors at Clippers: 10:00 PM ET (Play-In 9/10 Game, Prime Video)

The Clippers are 4.5-to-5.5-point home favorites at -205 on the moneyline. Golden State has lost four of its last five and went 1-10 against L.A. over the past two seasons. Kawhi Leonard is day-to-day with an ankle issue but expected to play. Steph Curry returned from a knee injury four games ago and shot 41.7% from three in that span. The loser’s season is over.

MLB Slate: Full Wednesday Schedule

Marquee MLB games tonight include Dodgers vs. Mets (Shohei Ohtani vs. Clay Holmes, 10:10 PM ET on ESPN, the Dodgers are 13-4 and -220 favorites), D-backs at Orioles (Eduardo Rodriguez vs. Kyle Bradish, 12:35 PM ET), and Blue Jays at Brewers (Dylan Cease vs. Chad Patrick, 7:40 PM ET). All tradeable on Kalshi.

Kalshi Promo Code vs. Kalshi Referral Code: What’s the Difference?

Most sites use these terms interchangeably. They are not the same thing.

What Is Kalshi? How It Works

Kalshi is a CFTC-regulated prediction exchange—structurally similar to the Chicago Mercantile Exchange. Instead of betting against a house, you trade contracts against other users on the outcomes of real events.

Each contract is a yes-or-no question. Example: “Will the Celtics win tonight?” If a Yes contract trades at $0.62, the market prices Boston at roughly 62% probability. You buy at $0.62. If Boston wins, the contract settles at $1.00 and you profit $0.38. If Boston loses, you lose your $0.62.

This federal regulatory status is why Kalshi operates in states where traditional sportsbooks are banned, including California, Texas, and Georgia.
