Kalshi assigns your tier at random once you complete $25 in qualifying trades on prediction markets. Roughly seven of every ten new accounts land on $15, and fewer than one percent reach $500. Plan to have $15 or $35 as your ceiling, and don't sign up expecting more.
One important note is that Illinois blocks Kalshi sports contracts. This means if you're attending White Sox-Cubs, you're unable to trade MLB odds.

White Sox vs. Cubs Odds Today: Kalshi vs. Polymarket

Kalshi prices the Cubs winning at a two cent cheaper price than one of their biggest competing prediction market apps, Polymarket. Another reason I rate Kalshi the best MLB prediction market app is because they often have the better priced odds of the two.
Our Expert White Sox vs. Cubs Pick
Take White Sox yes at 42c or better.
Kevin Gausman starts for the Cubs carrying a 4.53 ERA, and hitters punish him once his splitter flattens. The White Sox lineup slugs better than any team in baseball on a starter's third trip through the order.
The Cubs recently placed Dansby Swanson on the injured list with an oblique issue, thinning the infield behind a contact prone arm.
Chicago's south siders sit atop the AL Central after sweeping Detroit, and their bullpen ranks ninth in ERA with Sean Newcomb and Grant Taylor closing. My credit from Kalshi promo code ACTION goes on the White Sox.
