90% of the betting volume on Kalshi is betting on sports. I know how prediction markets work and how they're different that traditional sportsbooks, but they ultimately allow customers to do the same things.

If you are saying Kalshi isn't a sportsbook because the house isn't on the other side of the bet, you might as well argue that DraftKings isn't a sportsbook because they don't actually track your wagers in a book.
