Welcome Offer Explained
For new Kalshi customers looking to get a piece of today’s Final Four games, claiming this welcome offer is incredibly straightforward. To qualify for your $10 sign-up bonus, simply create an account and make a first-time deposit of at least $1.
Here is what makes this unique: Kalshi operates as a federally regulated exchange rather than a traditional sports betting platform. That means their prediction markets are available in all 50 states—you just need to be at least 18 years old to play.
Once you fund your account, the $10 bonus unlocks the moment you complete $10 in total trades on their markets. I love this approach because you can immediately apply your initial qualifying trades to today’s college hoops slate. With a tiny minimum deposit and an easy trading requirement, it is the perfect entry point for fans nationwide to get in the trenches.
Markets for Illinois-UConn and Michigan-Arizona
We have got an unbelievable slate today, with these Final Four matchups taking center stage in Indianapolis, Indiana, at Lucas Oil Stadium. Let’s look at the current lines for the big games:
| Matchup | Probability |
|---|---|
| Illinois vs UConn | ILL 55.2% / CONN 44.8% |
| Michigan vs Arizona | MICH 53.1% / ARIZ 46.9% |
Looking beyond the moneyline, the traditional markets have Illinois favored by 2.5 points against UConn with the game total sitting at 139.5. On the other side of the bracket, Michigan is laying 1.5 points against Arizona in what projects to be a shootout featuring a 157.5 over/under.
Let’s talk potential payouts. If we use our Kalshi funds to trade $10 on today’s heaviest moneyline favorite, Illinois, a winning ticket returns a solid $7.35 profit. On the flip side, if you are hunting for a bigger payout and place that same $10 trade on the heaviest underdog, you’re looking at an $11.40 profit if the Huskies pull off the upset.
Both of these games are true heavyweight clashes. In our first colossal matchup, AP No. 2 Arizona (32-2) faces off against AP No. 3 Michigan (31-3). The Wolverines carry the No. 1 overall RPI ranking in the country, just barely edging out the Wildcats’ No. 2 RPI standing.
In the other matchup, AP No. 7 UConn (29-5) takes on AP No. 13 Illinois (24-8). The Huskies boast a No. 4 RPI spot and a stellar 15-2 home record on the season—though this neutral-site game at Lucas Oil Stadium levels the playing field against a tough Fighting Illini squad that sits right behind them at No. 7 in the RPI rankings.
