Offer Overview

As the excitement of today’s college basketball slate unfolds, new customers have a unique opportunity to capitalize on the action. By registering with the platform, new users can secure a $10 sign-up bonus to use across a wide variety of prediction markets. I always tell bettors that to kick off the process and qualify for the offer, you simply need to create your account and make a first-time deposit of at least $1.

Once your initial deposit is complete, the $10 bonus will be unlocked immediately after you have made $10 in trades on their prediction markets. Whether you are trading on the outcomes of today’s college hoops matchups or predicting tournament futures, hitting that initial $10 trading threshold is all it takes to receive your reward. Best of all, Kalshi’s prediction markets are widely accessible—the platform is available in all 50 states, and users must be at least 18 to play.

Round of 32 Games on Saturday

MatchupProbability
Louisville @ Michigan State34.2% / 65.8%
TCU @ Duke15.1% / 84.9%
Texas A\&M @ Houston18.2% / 81.8%
VCU @ Illinois17.6% / 82.4%
Vanderbilt @ Nebraska53.3% / 46.7%
High Point @ Arkansas15.5% / 84.5%

Beyond trading on straight winners using the probabilities above, you can also look at the game spreads—ranging from Vanderbilt’s tight -1.5 margin to Duke’s massive -11.5 line—and totals that span from 140.5 (TCU/Duke) up to 168.5 (High Point/Arkansas).

If you use your funds on today’s heaviest favorite, a $10 trade on Duke’s high probability would yield a modest $1.27 profit if they advance. Conversely, placing that same $10 on the day’s biggest underdog, TCU, would return a substantial $53.50 profit if the Horned Frogs secure the upset.

Steps to Get a $10 Bonus with the Kalshi March Madness Promo Code

Unlocking your welcome offer is a quick and straightforward process. Follow these simple steps to activate the Kalshi promotion and secure your bonus:

  1. Register Your Account: Create a new account by providing standard personal information. As part of a safe and secure process, you will also need to provide proof of identification to verify your identity.
  2. Enter the Code: Be sure to explicitly enter the promo code DIME during the registration process to ensure your account is linked to the welcome offer.
  3. Make a Deposit: Once your account is set up and verified, fund your wallet by making a first-time deposit of at least $1.
  4. Start Trading: To fully activate the offer, you must make $10 worth of trades on the platform. Keep in mind that you do not have to make any single trade worth $10; a cumulative sum of $10 across multiple smaller trades will easily satisfy the requirement before the $10 sign-up bonus becomes available.

As soon as your total trades reach that $10 threshold, your $10 sign-up bonus will be ready and waiting in your account, giving you extra ammunition for the rest of the tournament.
