Offer Overview

This exclusive offer is specifically tailored for new Kalshi customers who want to step up their game during today’s exciting college basketball slate. By creating your account, you can secure a $10 sign-up bonus to use on any of the massive collegiate matchups hitting the hardwood. Kalshi’s unique prediction markets are accessible nationwide, meaning this welcome offer is available to users in all 50 states, provided you are at least 18 years old to play.

Claiming your welcome reward is a straightforward process designed to get us into the action quickly. To activate the promotion, new users simply need to make a first-time deposit of at least $1 into their account. From there, the $10 bonus will be fully unlocked after you have made $10 in trades on Kalshi’s prediction markets.

Once those initial trades are locked in, your bonus funds hit your account, giving you the extra capital you need to forecast the outcomes of today’s biggest games.

College Basketball Games and Markets for Saturday

MatchupProbability
Saint Louis @ MichiganSLU 13.8% / MICH 86.2%
Louisville @ Michigan StateLOU 36.4% / MSU 63.6%
TCU @ DukeTCU 15.0% / DUKE 85.0%
Texas A\&M @ HoustonTXAM 19.7% / HOU 80.3%
VCU @ IllinoisVCU 18.4% / ILL 81.6%
Vanderbilt @ NebraskaVAN 54.2% / NEB 45.8%
High Point @ ArkansasHP 15.5% / ARK 84.5%

Beyond these standard moneylines, you’ll also see point spreads and totals on the board. For example, Michigan is laying -12.5 points against Saint Louis with a high total set at 161.5, while Duke is favored by -11.5 points over TCU with an over/under of 140.5.

To put this in perspective for our bankrolls: if I trade $10 on today’s heaviest favorite, the Michigan Wolverines, we’re looking at a modest $1.11 in profit. But if we swing for the fences and place that same $10 on the heaviest underdog, the Saint Louis Billikens, a road upset would yield a massive $59.10 payout.

How to Unlock the Kalshi March Madness Promo

Securing your sign-up bonus before tip-off is quick and painless. I always make sure to follow the steps exactly so I don’t leave any money on the table. Follow this simple guide to activate the promotion and start trading:

  1. Register Your Account: Create a new account here by entering your standard personal information. You will also need to provide proof of identification to securely verify your identity.
  2. Use the Promo Code: During the registration process, make sure to enter the promo code SDS to officially opt into this specific welcome offer.
  3. Make a Qualifying Deposit: Once your account is fully verified, make a first-time deposit of at least $1.
  4. Place Your Trades: To unlock your reward, you must make $10 worth of trades on Kalshi’s prediction markets. The best part? You do not need to make a single trade worth $10. We can spread our predictions across multiple games, just as long as the total sum of the trades reaches that $10 threshold.

After your cumulative trades hit $10, your $10 sign-up bonus will be unlocked and credited to your account. From there, you’re ready to use those bonus funds for a real chance at a nice payday on all the exciting matchups throughout the weekend.
