KalshiEX, the platform, makes a bit more money from losers because they subsidize sophisticated winners through their market maker program.

Kalshi Trading LLC, the market maker which is fully owned by KalshiEX and has no independent online presence, makes money from losers in the same way as traditional gambling platforms. Kalshi's claims that this is an independent company are obviously absurd. (It's fair, I think, to say that the structure of the market limits their ability to make windfalls from severe mispricing.)
