What is Kalshi?
Kalshi is a financial exchange platform where users buy and sell shares of contracts on prediction markets. To translate that to the NCAA Tournament, you predict an outcome in college basketball in an attempt to win money, similarly to a stock market.
Whenever you buy a share of a prediction market contract, you make a trade. Use the Kalshi referral promo code ACTION and unlock $10 to trade with once you place your own $10 prediction.
Another important note about Kalshi is the house doesn't decide the implied probabilities on your wagers. Instead, that distinction falls on the volume that's traded on each individual market.
Expert Sant Louis vs. Michigan Prediction to Make on Kalshi Today
Of all the Round of 32 games today, Saint Louis vs. Michigan at 12:10 p.m. ET on CBS catches my eye most. Michigan had a scare in their Round of 64 game before pulling it together, while Saint Louis upset Georgia and won by a dominant 25 points.
Action Network expert Mike McNamara has a Saint Louis vs. Michigan prediction of Michigan wins by over 12.5 points NO (1.90x), which is one I firmly back to trade on at Kalshi today:
"The Billikens were arguably the most impressive team of day one of the NCAA Tournament, and I expect them to put forth another strong performance on Saturday in the Round of 32.in terms of covering this double-digit number? I see plenty of value on Saint Louis to hang tough and keep this inside single digits throughout."
