Kalshi Promo Code Breakdown:

The Kalshi welcome offer is about as easy as it gets: trade $10, get $10. After you sign up with a promo code and place at least $10 in trades, they’ll drop an extra $10 into your account to use.

Think of it as a little boost to get you going. You do need to make that first trade to unlock it, but once you do, the bonus usually shows up pretty fast.

A couple of key things to keep in mind:

• It’s only available for new users
• You need to trade $10 to unlock the bonus
• The extra funds are typically site credit (not cash you can withdraw right away)

Overall, it’s a low-pressure way to try Kalshi out—especially if you’re new to prediction markets and want a bit of extra balance to play around with.

Duke vs St. John's — 7:10 PM ET | NCAAB Sweet 16

Duke enters as the higher seed with a championship pedigree, but this spread feels inflated given the Blue Devils' injury concerns. St. John's has proven they can hang with elite competition, and the Red Storm's physicality could exploit Duke's depleted frontcourt rotation. Both teams advanced through the first weekend, but the Johnnies have been undervalued all tournament as a double-digit seed still dancing.

In 2015, teams missing a starter or key rotation piece are 14-22 ATS when favored by 6+ points. Take the points with the Johnnies in what should be a possession-by-possession battle.

Injuries:

🏥 Injuries

🟡 Caleb Foster (Duke) — Questionable, foot fracture, 50-50 to play

🟡 Patrick Ngongba II (Duke) — Questionable, right foot soreness, played 13 minutes vs TCU after 5-game absence

🔴 St. John's — No injuries reported

Pick: St. John's +6.5 — The Blue Devils are dealing with two key rotation pieces banged up, and Foster's potential absence removes a critical ball-handler who averages double figures. Ngongba is clearly not at full strength, managing just 13 minutes in his return. St. John's thrives in physical, grind-it-out games where the total stays under 145, and Duke's 50% health in the frontcourt means fewer second-chance opportunities. In Sweet 16 games since 2015, teams missing a starter or key rotation piece are 14-22 ATS when favored by 6+ points. Take the points with the Johnnies in what should be a possession-by-possession battle.
