How Kalshi Works
Kalshi lets you trade yes-or-no contracts on real events: elections, weather, economic data, pop culture, and sports. You buy a contract when you expect an outcome to happen and sell when you don't. Prices move with the market, so you can lock in gains or cut losses before an event even ends.
Because Kalshi runs as one of the federally regulated prediction market apps exchanges under the CFTC, it behaves more like a trading floor than a bookmaker. That structure strips out the traditional house edge and lets traders set their own prices.
In fact, Underdog recently went live with their own prediction market exchange. This is a sign that prediction markets are only going to increase in popularity over time, as more platforms seek CFTC regulation approval.
Is Kalshi Legal?
Yes. Kalshi operates legally nationwide with the following exceptions: AZ, IL, MA, MD, MI, MT, NV, and OH. This means the Kalshi promo code ACTION is redeemable in 42 states, in addition to Washington D.C. today, July 25, 2026.
Trading Padres vs. Marlins on Kalshi
Today's matchup gives new traders a live event to test the markets. San Diego rolls in swinging hot bats, with Manny Machado and Xander Bogaerts anchoring the lineup. Meanwhile, Miami keeps clawing toward .500 behind a rotation that has flashed real upside since the All-Star break concluded.
Kalshi lets you trade the result directly. Back the Padres to win, side with the Marlins at home, or trade the game total, all in a few taps. Prices shift as lineups drop and first pitch nears, so early traders often grab the best value before the market catches up. Watch the contract move in real time, and sell your position mid-game if the score swings your way.
You can also ride the momentum into other markets. Trade a division race, a player milestone, or the next headline event once first pitch settles.
