How Do You Trade on Kalshi?

Kalshi allows players in North America to buy and sell shares of contracts centered around real-world outcomes. These outcomes cover sports like college basketball, pop culture, the political landscape, economy, and weather. The best comparison I have for Kalshi is that it's similar to a stock market. A major difference between Kalshi and online sportsbooks is that Kalshi doesn't set implied probabilities. On a sports betting site, the house sets the odds, whereas the volume being traded on Kalshi prediction markets is what sets implied probabilities.

Ways to Trade March Madness First Four Prediction Markets

I already mentioned the various Kalshi prediction markets available for the NCAA Tournament. The Tennessee vs. Virginia March Madness prediction I like most today is Tennessee wins by over 1.5 points NO (1.86x). In particular, I feel good about this Tennessee vs. Virginia prediction because it's backed by Action Network expert Ryan Minion, who says:

"I think Tennessee is being over-valued in this spot, given its first half versus Miami (OH), and Odom’s perimeter defense allowing an outlier shooting performance to a mediocre Raiders squad. I feel good backing Virginia getting 1.5 points, and I'm most concerned about the impact Ament will make at both ends of the floor."
